general description

introduction andoverview

UM␣ link is an SNMP adapter designed formanagement of UPSs manufactured byMGE UPS SYSTEMS. UM␣ link allowsconnection of four UPSs to a networkstation running an SNMP-basedmanagement software such SOLUTION-PAC, MANAGEMENT-PAC or HP Open Viewto monitor the status of the UPSs as wellas to configure them.

UM␣ link is equipped with built-in SNMPagent software and processing hardware,an Ethernet port, and four communica-tions ports for UPS connections,permitting management of the UPSsfrom␣ a network manager station usinga␣ standard management protocol.

about this release ofUM␣ link

This release of UM␣ link implements manynew features and enhancedfunctionalities which are summarizedhereafter:

◗ Dual power supply: Two Input ACpower adapter’s sockets allow to havetwo different source of power to supplyto the UM␣ link SNMP adapter.

◗ Serial Line Internet Protocol (SLIP)available on the COM1 UM␣ link serialport. This Internet protocol is used to runIP over the serial RS-232 cableinterconnecting UM␣ link with anothersystem such as an UM view Out-of-Bandmanagement application.

◗ BootP client: This Internet protocolallows UM␣ link to discover some startup

information, such as its IP addresses,from another system which acts as abootP server (for example an UM viewmanagement application).

◗ Trivial File Transfer Protocol(TFTP): This Internet protocol is used totransfer configuration data to the UM␣ linkAdapter from files found on a host system.

◗ IETF standard UPS MIB: The InternetEngineering Task Force (IETF) haspublished a new portion of theManagement Information Base (MIB) formanaging Uninterruptible Power Supply(UPS) systems. These objects are part ofthe UPS MIB defined in RFC1628 and areimplemented in this UM␣ link releasemaking mib2.33 MIB subtree availablefrom a management application.Configuration parameters allow yourUM␣ link adapter to send standard SNMPIETF traps or entreprise specific MGEtraps to any manager on the network.

◗ Shutdown / restart sequences: Thisfunctionality allowing automaticmanagement of scheduled on/offsequences has been implemented to beused with latest release of MGE UPSs.

◗ UM␣ link serial communication toUPSs has been improved to handle moreMGE varieties of UPS models.

The installation of UM␣ link consists of anumber of steps, which are described inthe following sections.

connection to network

One port is provided for connection to anEthernet network. For installationflexibility, this port is equipped with twoconnector types: (1) an RJ-45 connectorfor use with the unshielded twisted-pair(UTP) cable and (2) a BNC connector foruse with the thin coaxial cable. You canuse only one connector at a time. If youuse the BNC connector, do not use theRJ-45 connector. Vice versa, if you usethe RJ5-45 connector, do not use the BNCconnector.

You may disconnect the network cablefrom one connector and connect it to theother connector anytime, even duringthe course of UM␣ link’s operation.UM␣ link detects which connector is beingconnected to the network andautomatically switches network datatransfer through this connector.

Connecting to UTP cable

Normally, the RJ-45 connector should beconnected to the network through a

10BASE-T Ethernet hub. The cable thatconnects to the hub is a straight-throughUTP cable (see the UTP cable wiringdiagram at the end of the manual).

You may also connect the RJ-45connector directly to a 10BASE-Tinterface (Ethernet adapter) in the PC thatruns SOLUTION-PAC, MANAGEMENT-PACor open view. In this case, the UM␣ linkand the PC are the only two nodes on thenetwork. If you select this type ofconnection, use a cross-wired UTP cable(see the UTP cable wiring diagram at theend of the manual).

Connecting to thin coaxial cable

Note: If you leave any open end on theT-connector, attach a 50-ohm terminatorto this end.

connecting to UPSs

Each UPS is equipped with acommunications (COM) port. Four COMports are provided on the UM␣ link forconnection to four UPSs. If you haveinstalled more than four UPSs on your

RJ-45 connector to Ethernet hub

network, use additional UM␣ links toconnect them.

Caution: You should use the cablessupplied with the UPS to connect theUM-LInk to the UPSs. Mark these cablesclearly to avoid mistakes. These cablescan only be used for communicationbetween the UM␣ link and MGE UPSs (andnot necessarily other vendors’UPSs).

You can also use standard 3-wire straight-through serial cables.

There are many other ways to connectUPSs to your UM␣ link adapter depending

To UPSor mains

on the model and location of thesesystems:

◗ You can connect a Merlin Gerin“2␣ Contacts” UPS through a specificadapter which converts these drycontacts to RS-232 ascii commands.

◗ You can use a “UM sensor” interfacewhich will provide externally supplieddry contacts and other information suchas temperature and humidity to yourUM␣ link adapter.

◗ You can also establish connection to aremote UPS using automatic responsemodems.

connecting AC␣ poweradapter

There is no power switch on the UM␣ link.The power is turned ON as soon as theAC power adapter is connected.

Caution: Check the input AC powervoltage before you connect the AC poweradapter. The voltage and rating of the ACpower adapter are indicated on its label.If the specifications of the input ACpower and the AC power adapter are notcompatible, do NOT connect the AC


power adapter. You will risk damage toboth the AC power adapter and theUM␣ link. Change to a proper AC poweradapter or contact your reseller to obtaina correct one.

You have also possibility to use a secondAC power adapter with same specificationas the one which is provided with yourUM␣ link package. In that case, the firstavailable source which is connected tothe UM␣ link will supply power to theSNMP adapter. If a power failure occurson this source, UM␣ link will automaticallyswitch the power entry to the secondsource.

Not all of MGE UPSs have outputcompatible with the power adapter plug.You may have to purchase specificCE22/FT-UL adapters.

checking LED lights

A power-on self test (POST) should takeplace when the AC power adapter isconnected. A successful completion ofthis test indicates that there is no problemwith the UM␣ link. You can proceed to thenormal operation of UM␣ link.

◗ If POST successfully completes, each ofthe “COM” LED lights should flash once,starting from LED “1”, then LED “2”, LED“3”, LED “4”; afterward, they should flashone more time in the backward direction,starting from LED “3”, then LED “2”, thenLED “1”.

Subsequently, (1) the “power” LED lightshould be ON, (2) the “link” LED lightshould be ON (if the UTP cable isconnected and the power of the Ethernethub to which the UM␣ link is connected isturned ON), (3) the “Tx” LED light shouldblink (when there is network data goingthrough the UM␣ link), (4) the “collision”LED might occasionally blink (whenheavy network traffic occurs), and (5) the“COM” LED lights (of the COM ports thatare connected to the UPS in operation)should also blink.

◗ If POST fails, all four “COM” LED lightsshould flash continuously. Refer tosections “Power-on LED display sequence”and section “Using diagnostic program”for instruction details.

checking NMSconnection

The network manager system (NMS)should be running an SNMP-basednetwork management program such asSOLUTION-PAC, MANAGEMENT-PAC(programs specifically designed tomanage the UPSs through UM␣ link) or HP-open view.

The SNMP agent software inside UM␣ linkcontains a set of default configuration.This default configuration includes an IPaddress and Community Name, amongothers, that screen access from an NMSto the UM␣ link (and in turn, to the UPSs).

If your NMS uses the same configuration,you should be able to see the UPSs(those connected to UM␣ link) on thescreen of the PC running SOLUTION-PAC,MANAGEMENT-PAC. If not, you will haveto change the UM␣ link’s “agentconfiguration”. Refer to section “Usingterminal program” for how to change this“agent configuration”.


This section tells you how to configurethe SNMP agent software residing in theUM␣ link’s hardware. This agent softwareallows the UPSs connected to UM␣ link tocommunicate with a network managersystem (NMS) running an SNMP-basedmanagement software.

The following lists the default agent soft-ware configuration. Four sets of defaultconfiguration are kept, each for␣ one ofthe four UPSs connectable to UM␣ link.

◗ IP address: 168.8.xx.aa◗ Subnet mask: 255.255.0.0◗ Gateway: 0.0.0.0◗ Baud rate: 2,400 bps◗ UPS polling rate: 1,000 ms◗ Trap ACK timeout: 5 sec◗ Trap ACK retry: 6 times◗ Community name-RO: public◗ Community name-RW: public◗ BootP enabled: YES◗ TFTP enabled : NO◗ Auto learning enabled : NO

The program used to change thisconfiguration is the terminal program,which is built into the UM␣ link.

Note: In addition to this built-in terminalprogram, you may also use the SNMP-based UM view management program to

alter UM␣ link’s COM ports’ defaultconfiguration. UM view can be installedon a PC for comprehensive configurationand status/statistic monitoring of theUPSs through UM␣ link.

accessing terminalprogram

The terminal program built into theUM␣ link can be accessed by connecting aVT100 terminal to UM␣ link’s COM1 port.If you have a PC, run a VT100 terminalemulation program. The procedure isdescribed below:

1- You may access the terminal programanytime while the UM␣ link is inoperation. You may not access theterminal program if UM␣ link’s POSTcannot be successfully completed.

2- Configure the COM port of theterminal as follows:

❍ 2400 bps❍ No parity❍ 8 data bits❍ 1 stop bit

Note: If using Windows 3.x terminal.exeemulator, do not select “Use function key

arrows and ctrl” in the “terminalparameters” menu.

This is the configuration of UM␣ link’sCOM1 port while the UM␣ link is in theoperation mode.

3- Connect UM␣ link’s COM1 port to theterminal using the cable provided withyour UM␣ link.

setting agentconfiguration

“Agent configuration” on the main menucan be selected to change the defaultagent software configuration for each of

the four UPSs connected to the UM␣ link.Note that the configuration will be savedin the UM␣ link’s memory, so it does notmatter whether the UPSs are actuallyconnected to the COM ports.

1- Select “Agent configuration” from themain menu to display the following screen:


UPS unit: 1

Agent MAC address 0080c80d2023IP address 168.8.32.35Subnet mask 255.255.0.0Default gateway 0.0.0.0Baud rate 2400UPS polling rate (ms) 1000Trap ACK timeout (sec) 5Trap retry count 6Community name-RO publicCommunity name-RW publicBOOTP enable YESTFTP enable NOAuto learning enabled NO

2- The screen initially displays the agentconfiguration of “UPS unit 1” (i.e. COM1port). To select the next “UPS unit”, pressF3 once. To select the previous “UPS unit”(i.e. COM 4 port), press F3 three times.

3- To change any configuration, positionthe cursor on the desired field, thenovertype the value being displayed.

4- To save the new configuration in theUM␣ link, press F2.

5- Repeat steps 2, 3, 4 above to setconfiguration for all other COM ports.

The following explains the meanings ofthe configuraiton fields.

◗ MAC address: This is the Ethernetdata link layer address burned into anEPROM inside the UM␣ link. The address islabeled on the UM␣ link metal case.

◗ IP address: Each COM port has adefault IP address of 168.8.xx.aa, wherexx and aa are identical to the last twobytes of the UM␣ link’s MAC address forCOM1, and aa is the last byte + 1 forCOM2, + 2 for COM3 and + 3 for COM4.Usually, this default IP address must bechanged in order for the COM ports tocommunicate with an NMS. Consult yournetwork administrator and assign a newIP address for each port.NOTE: IP address 0.0.0.0 means theunit is disabled.

◗ Subnet mask: This is used to mask thenetwork ID part of the IP address. Thedefault value is 255.255.0.0. You maychange the default to fit one of the threeclasses of subnets:❍ Class Ainternet address: 255.0.0.0.❍ Class Binternet address: 255.255.0.0.❍ Class Cinternet address: 255.255.255.0.

◗ Default gateway: This is the IPaddress of the gateway. If the NMS andthe UM␣ link are not on the same network,the IP address of the gateway must bespecified for to tell UM␣ link how to findthe NMS. The default value is 0.0.0.0,meaning there is no gateway.


◗ Baud rate: The baud rate is fixed at2,400 bps for each COM port in theoperation mode (when in communicationwith the UPS).

◗ UPS polling rate: This is the timeinterval for the COM port to poll its UPSfor status. The default value is 1,000 ms.The configuration range is 500 - 3,000 ms.

◗ Trap ACK timeout: This is the timeoutfor trap receive acknowledgement. If thereis no ACK at timeout, a trap resend willbe retried from the UM␣ link to an NMS.

◗ Trap retry count: This is the numberof times UM␣ link retries to send a trap forwhich no acknowledgement has beenreceived from the NMS.

◗ Community name-RO: This parameteris the common community name whichprovides the read-only access right.

◗ Community name-RW: This parameteris the common community name whichprovides the read-write access right.A community name is a character stringwhich is used to check the access right toeach of the COM port (hence, its connec-ted UPS). Only NMS having the sameCommunity name as set for the COMport will be allowed to access the UPS.For SNMP SET request, a manager shoulduse the ReadWrite community name. ForSNMP GET and GET_NEXT requests, amanager can use either the Read-Writecommunity name or the Read-Onlycommunity name.

◗ BootP enabled: This is the parameterenabling or disabling the bootP process.

The bootstrap protocol is an Internetstandard protocol used to get from aworkstation (bootP server) an IP addressand a bootfile name.

◗ TFTP enabled: This is the parameterenabling or disabling the use of the TrivialFile Transfer Protocol for transfering filesfrom an ghost workstation to the UM␣ link(software or configuration download).

The bootstrap process and downloadfunctionality are described hereafter withregards to the different combinations:

BootP TFTP UM␣ link process

YES YES At power on time, UM␣ link will usebootP to get IP address andbootfile name on the network(from a bootP server). It will thenuse TFTP to get the bootfile(software upgrade throughdownloading this file). It will alsorespond to further TFTP requestfor both software download andconfiguration download.

YES NO At power on time, UM␣ link will usebootP to get IP address andbootfile name on the network.Nothing further will be done (nosoftware upgrade), and it will notrespond to TFTP write request(neither software download norconfiguration download).

NO YES Not any bootP process will beenacted at power on time. UM␣ linkwill respond to further TFTP writerequest (software download andconfiguration download).

NO NO UM␣ link will do neither bootPoperations nor software/configuration download via TFTP.

◗ Auto learning enabled: This is theparameter enabling or disabling the socalled “auto learning” process. Thisfunctionality when enabled createautomatic insertion in the MGE MIBmanager table of a default descriptionfor any new manager accessing theUM␣ link UPS agent. The manager isautomatically inserted in the table onlyif␣ the request made (SNMP SET or GET orGET_NEXT) was accepted by the UM␣ linkSNMP agent. This will give this managerability to receive traps, even if it doesnot have write access to the agent withSNMP set commands.

Although these three later parameters(bootP, TFTP & autolearning) can be setfor any of the four COM ports of theUM␣ link, only one value is memorized tomaintain consistency. Thus, when youwill modify one of this objects for a COMports it will modify the objects on theother 3 ports.

setting manager tables

“Manager table” on the main menu canbe selected to set up a list of NMSs.

For each UPS, you can set up a tableconsisting of a number of NMSs that youallow to manage. In this table, you willspecify the IP addresses of the NMSs, andthe community names that they mustprovide to gain access to the UPS. Trapswill be automatically sent from theUM␣ link to these NMSs.


NMSs whose IP addresses are not foundin the table, or NMSs that provide theincorrect community names can stillmanage the UPSs if they know the IPaddresses and community names of theCOM ports (in the UM␣ link) to which theUPSs are connected (see section “Settingagent configuration”).

1- Select “manager table” from the mainmenu to display the following screen:


UPS unit: 1Manager table (I)

6.__________ ___ ____ _________ ____

7.__________ ___ ____ _________ ____

8.__________ ___ ____ _________ ____

2- The screen initially displays the tablefor “UPS unit 1” (i.e. COM1 port). Toselect the next “UPS unit”, press F3 once.To select the previous “UPS unit” (COM4port), press F3 three times.

3- The table is initially blank. If you haveset up a table for the COM port before,the IP addresses, community names andothers will be listed. You can make thechanges by overtyping what is beingdisplayed.

There are many entries for each COMports. The exact number of entriesdepends on the version of firmwareinside the UM␣ link. Eight entries aredisplayed on a screen. To display thenext eight entries (if available), press “+”.To display the previous eight entries,press “–”.

4- For each NMS, type in an IP address, atrap level and a community name. Seethe explanation below for the meaningof “trap level”. To select a type of NMS,press the space bar to toggle among theselection.

To change any configuration, positionthe cursor on the desired field, thenovertype the value being displayed.

5- Press F2 to save the table in theUM␣ link.

6- Repeat steps 2 to 5 above to set up atable for all other COM ports.

The following explains the meanings ofthe fields.

◗ IP address: This is the IP address ofthe NMS.

◗ NMS: This field lists the name of theSNMP network management programsoftware installed on the NMS. Whenadding manager on this table, youshould not let NMS remain empty.Empty␣ value for this field is related tointernal management of the autolearningprocess.◗ Trap level: A trap is a messagereporting the event occuring at the UPS

side. Traps are grouped into levelsaccording to the seriousness of theevents. Trap level 7 signifies the leastserious events, while trap level 1signifies the most serious events. A traplevel can be set from 0 to 7. If youspecify the trap level to be 0, no trapswill be sent. If you specify the trap levelto be 3, traps belonging to levels equalto and smaller than 3 (levels 1, 2 and 3)will be sent to the NMS. Refer to themanuals of the SNMP software programsfor the grouping of traps by levels.

◗ Community name: This parameter isthe manager community name which willbe used by UM␣ link when sending trapsto the manager.

◗ Trap ack: This is the parameter enablingor disabling the acknowledgementprocess when sending traps to a specificmanager.

Setting MG NOACK to this parameter willindicate that this manager will receiveMGE Enterprise Traps but will notacknowledge these traps. Then UM␣ linkwill send trap to this manager only once.

Setting MG ACK to this parameter willallow this manager to receive MGEenterprise traps. The Trap will be sentagain to this manager until it isacknowledged by the manager or it hasbeen already sent too many times (seesection “Setting agent configuration”for␣ parameters configuring theacknowledgement process).Setting IETF NOACK to this parameterwill indicate that this manager will receive


IETF traps and will not adknowledgethem (see agentmib.doc for IETF trapsdescription). In that case MGE entreprisetraps will not be sent to this manager.

duplicatingconfiguration

“Duplicate configuration” on the mainmenu can be selected to duplicate theconfiguration that you have set for oneCOM port to another COM port. Theduplication process can be between anytwo COM ports of the same UM␣ link. Youcan use this function to simplify operationby copying the configuration from onesource, then make modifications on thecopied configuration at the destination.

1- Select “Duplicate configuration” fromthe main menu to display the followingscreen:


Duplicate configuration:

Source unit ____________

Destination unit ____________

IP of destination unit ____________

2- Type in the numbers of the source anddestination (1 to 4). Type in the IPaddress of the destination unit.

3- Press F3 to start copying.

software-resetting aIICOM ports

The selection “factory reset” on the mainmenu can be used to perform a reset ofall COM ports’ configuration.A reset reverts all configuration settingsof the COM ports to their factory-setdefault settings. See the beginning ofthis section “Using terminal program” fora list of default settings.Note that this function has the sameeffect as pressing continuously the“reset” switch on the back panel of theUM␣ link, power off and on UM␣ link andwait until LED lights 3a, 3b, 3c, 3d blinktogether four times.

To reset the configuration of the COMports to their default values, do asfollows:

1- Select “factory reset” from the mainmenu.

2- Press F3 to reset.


Confirm to factoryreset on device ___________


hardware-resetting all COM ports

The “Reset” switch on the UM␣ link’s backpanel is used to reset all COM ports’configuration to their default values. Thedefault values are listed at the beginningof section “Using terminal program”.The hardware reset operation must bedone when the UM␣ link’s power is turnedON and while a system boot is beingperformed.

1- If the power of the UM␣ link has beenturned ON, turn it OFF by disconnectingthe AC power adapter.

2- Re-connect the AC power adapter toboot.

3- Use a pen tip, depress the “Reset”switch and keep this switch pressed untilthe power-on self test (POST) of theUM␣ link is completed. To find out whenPOST is completed, see the next section.

4- Check the “COM” LED lights to verifythe configuration reset. All four “COM”LED lights should flash four times toindicate that a reset has taken effect.


This section describes the UM␣ link’spower-on self test (POST). The LED lightson the front panel are used to indicateresults of each of sub-tests that comprisePOST. The results for the sub-test canalso be displayed on the screen byconnecting a VT100 terminal to theUM␣ link’s COM1 port. Refer to section“Using diagnostic program”, for details.

LED lights used by power-on self-test

1- As soon as the AC power adapter isconnected to the UM␣ link, the “power”LED light (1) should be ON; all other LEDlights except for “collision” (2a) and“Tx”␣ (2c) should blink momentarily, thenturn OFF.

2- Subsequently, the following sub-testswill be performed. LED lights (3a), (3b),(3c) and (3d) are used to indicate theresults of these sub-tests. If a sub-testsfails, its LED light(s) should blink fivetimes, then the UM␣ link will enter thediagnostic mode; all subsequent sub-tests will be suspended. You will knowthat the UM␣ link is in the diagnosticmode when all four LED lights (3a), (3b),(3c) and (3d) blink continuously.You should then connect UM␣ link’sCOM1 port to a terminal to run thediagnostics.The following indicates which LEDlight(s) is/are used by which sub-test.

3- If all sub-tests succeed, each of the“COM” LED lights should flash once,

power-on LED display sequence


when should you rundiagnostic program?

When the UM␣ link is powered ON(AC␣ power adapter is connnected), apower-on self test (POST) should takeplace. POST consists of a number of sub-test, each verifying a particularcomponent of the UM␣ link.

Some components are more critical to theoperation of the UM␣ link. For example, ifthe CPU malfunctions, the UM␣ link willnot work. Or, if the software programcodes in the flash memory are lostdamaged, a software download must beperformed before the UM␣ link cansuccessfully run.

In case a sub-test of a critical componentfails, UM␣ link will automatically enter intothe diagnostic mode. You should thenconnect the UM␣ link’s COM1 port to aterminal to display the test results andperform diagnostic functions.

In case all sub-tests succeed but youwant to download a new configurationfile or system program codes to theUM␣ link, you should also connect theUM␣ link’s COM1 port to terminal to runthe diagnostic program.

When all four COM LED lights flashcontinuously and endlessly, the UM␣ linkis in the diagnostic mode. Within fiveseconds after a screen message isdisplayed, press “+” to allow the terminalto communicate with the UM␣ link in thisdiagnostic mode.

connecting toterminal

COM1 port is used for diagnostics. Thefollowing lists the configuration of thisport while the UM␣ link is in thediagnostic mode:

◗ 9600 bps◗ No parity◗ 8 data bits◗ 1 stop bit

1- Prepare a VT100 terminal. If you havea PC, run a VT100 emulation program tohave the PC emulate a VT100. Set theterminal’s (or PC’s) COM port to the sameconfiguration as the UM␣ link’s COM1port’s (shown above).

2- Connect UM␣ link’s COM1 port to theterminal using the cable provided withyour UM␣ link.

3- Within 5 seconds, hit the “+” characteron the terminal’s keyboard to enter thediagnostic program. If you do not to hitthis character in time, the terminal will failto connect to the UM␣ link’s diagnostic pro-gram. In this case, disconnect the AC poweradapter from UM␣ link, then re-connect itto start the power-on self test again.

checking result of selftest

Function 1, “Show self test result” in thediagnostic program␣ is main menu can beused to display the result of the UM␣ link’spower-on self test. This self test consistsof a number of sub-tests. The results ofthese sub-tests will be displayed on thescreen after you select 1 from the mainmenu. The following shows an examplescreen.

Note that if there is a hardware problemand the self test terminated somewherein the middle, the sub-tests that aresubsequent to the one that failed will notbe carried out. In this case, the screenwill only display the results of the sub-tests that were performed.

downloadingconfiguration file

Function 2, “Download configuration” inthe diagnostic program’s main menu canbe used to download the configurationfrom a disk file to the UM␣ link’s EEPROM.This function is useful when theconfiguration stored in the EEPROMbecomes lost, and you can download thepreviously set configuration from a diskfile to the EEPROM. Or when youchanged the hardware configuration (e.g.connecting different types of UPSs to theUM␣ link), and a different configurationmust be set in the EEPROM.

Use the software programs that MGE UPSSYSTEMS provides to prepare anddownload configuration files. When you

select 2 from the main menu, you will beprompted to exit from the terminalprogram and execute a program todownload configuration.

Please run “dloadcfg.exe” from thedistribution diskette. Select 9600baud on the first menu. It will take30 seconds to complete. Hit <cr> tocontinue, or any other key to abort...

Specify the drive and path of theconfiguration file to download theconfiguration file’s content to theUM␣ link’s EEPROM, overwriting whateveris residing in the EEPROM.

Note: Note that MGE “MANAGEMENT-PAC” also provides functions fordownload of configuration files. If youwish to use “MANAGEMENT-PAC” instead


of the diagnostic program, install“MANAGEMENT-PAC” on a PC anddownload a configuration file to theUM␣ link from this PC.

The limitation on the file that can bedownloaded with the dloadcfg.exeprogram is 239 lines. This file shouldhave “.cfg” extension name. It is an ASCIIfile with following syntax:

◗ First line is the “Configurationsignature”.

It includes four fields, which are the MIBversion number string, the MIB objectidentification, the configuration filename, and the date of the configurationfile. Only the first two fields are required.Tabulation or Space are used asseparators between fields.

Example: For version 1.6 of UM␣ link, thesignature line should be:“1.6” 705.1

◗ Each one of the other lines in theConfiguration file describes a configu-ration value to be set to a MIB object.

It includes four fields which are theobject_value, the object_id_number, theobject_id_name and the comment.

Only the first two fields are required.

Tabulation or Space are used asseparators between fields.

The object_value is a string, an integer,or an IP address.

The object_id_number, is the MIB OIDstarting with the MIB object identificationprefix given in the signature line (705.1).

The object_id_name which is optional givesthe MIB object string identification. Theend of the line is managed as a comment.A sample of such lines could be:

“SV6” 705.1.1.2.0 upsidentModeIname The model name

4 705.1.2.2.1.4.1 managerCommType SNMPv1 for manager #1

4 705.1.2.2.1.4.2 managerCommType SNMPv1 for manager #2

168.8.0.43 705.1.2.2.1.6.5 managerAddress IP address manager #5

The default.cfg files which are providedwith the UM␣ link package are samplefiles giving the object_id_number for alist of MIB configuration objects.

upgrading software

UM␣ link’s flash memory contains thesystem software program codes. Theseprogram codes comprise the SNMPagent, the communication program withthe UPSs, the terminal program andothers that are inside the UM␣ link. Whenthe codes are lost or damaged, youshould download the newest version ofthese codes to the UM␣ link to make itwork. Or when a new version of programcodes becomes available, you shouldupgrade the current ones bydownloading the new codes.

Function 3, “Software upgrade” in thediagnostic program’s main menu can beused to download the system programcodes to the UM␣ link’s flash memory.Once you have pressed 3 to invoke thefunction, the following message will bedisplayed on the screen:

Please run “download.exe” from thedistribution diskette. Select 9600baud on the first menu. It will take 5minutes to complete. Hit <Enter> tocontinue, or any other key to abort...

The baud rate of the PC’s COM portshould remain at 9,600 bps as describedin section 7.2. “Connecting to terminal”.Insert the diskette containing the program“download.exe”, then execute the pro-gram. Your PC will now enter the softwaredownload mode. Follow the screen promptto specify the file name and path for thesystem software program codes’file.

Note: Note that MGE “MANAGEMENT-PAC” software program also providesfacility for download of software. If youwish to use “MANAGEMENT-PAC” insteadof the diagnostic program, install“MANAGEMENT-PAC” on a PC. Softwaredownload to the UM␣ link can be carriedout from this PC.
