Nonport side of the switch

The nonport side of the switch is used solely for air flow. There are no features onthis side.

Supported fabric configurations

The switch is supported as an edge device in fabrics of up to 239 switches.

Additional port activation

The switch can be purchased with 8, 16, or 24 licensed ports. As your needsincrease, you can activate unlicensed ports by purchasing and installing theadditional 8 port activation feature. After it has been installed, the license appearsunder the licenseShow command as Ports on Demand license.

The additional ports are ready to be unlocked in the switch firmware. The licensemight be part of the licensed paper pack supplied with switch software, or you canpurchase the license separately from IBM, who will provide you with a key to unlockit.

By default, ports 0 through 7 are enabled on the switch. To enable ports 8 through16, install a Ports on Demand license key. To enable ports 16 through 24, installanother Ports on Demand license.

After you have installed the license keys, you must enable the ports. You can do sowithout disrupting switch operation by using the portEnable command on each portindividually. Alternatively, you can disable and reenable the switch to activate allports simultaneously.

To install the additional port activation license, you can either use the suppliedlicense key or generate a license key. Typically the switch is shipped with a paper

pack that specifies the transaction key to use with the Software License Keys link.

Use this transaction key at the following Web site: http://www.ibm.com/servers/storage/support/san.

1. On that page, from the Product list, select your product.

2. Select Download from the Support & downloads section.

3. From the page that is generated, select License request in the Tool/utilitysection.

4. Follow the instructions on that page to generate the key. You can also use thissite to generate other license keys for your switch.

ISL Trunking groups

The switch supports Interswitch Link (ISL) Trunking as a licensed feature. When thisfeature is enabled, create Trunked groups of up to 8 contiguous ports. This meansthat you can create up to three trunked groups that contain 8 ports each. The FibreChannel ports on the switch are numbered from left to right and color-coded withingroups of eight to indicate which ports you can combine into trunked groups.

v ATrunk Group 1: ports 0 through 7

v BTrunk Group 2: ports 8 through 15

v CTrunk Group 3: ports 16 through 23

Note: ISL Trunking is optional software that allows you to create trunking groups ofISLs between adjacent switches. For more information about trunking, referto the Fabric OS Administrators Guide.

Supported optional featuresThe switch supports the following optional software, which you can activate bypurchasing the corresponding license key:

v Extended Fabricallows implementation of long distance dynamic (LD) and longdistance static (LS) distance levels. This feature extends SAN fabrics beyond theFibre Channel standard 10 km by optimizing the internal switch buffers tomaintain performance on ISLs at distances up to 500 kilometers.

v Fabric Watchmonitors mission-critical switch operations. This feature isdesigned to enable real-time proactive awareness of the health, performance,and security of each switch. It automatically alerts network managers to problemsand helps avoid costly failures by providing:

Real-time tracking of numerous fabric and switch elements

Automatic event notifications when switch and fabric elements exceedthresholds

Security, availability, and congestion monitoring thresholds and alerts

v Adaptive Networking provides a set of capability allowing high priorityconnections to obtain the bandwidth necessary for optimum performance, even incongested environments.

v Advanced Performance Monitorprovides Performance Monitoring capability tohelp identify end-to-end bandwidth usage by host/target pairs and is designed toprovide information for capacity planning.

v Trunking Activationdesigned to enable Fibre Channel packets to be efficientlydistributed across multiple Inter-Switch connections (links) between two SAN

b-type fabric switches, while preserving in-order delivery. ISL Trunking issupported between any of the supported 2, 4, or 8 Gbps b-type models. BothSAN b-type fabric switches must have ISL Trunking activated.

In addition, customers can order a set of optional features bundled into oneorderable feature, the B24 Enterprise Package. This bundled feature consists ofone of each of Fabric Watch, Trunking Activation, Advanced Performance Monitor,Adaptive Networking, and two 8-Port Activations.

Chapter 2. Installing and configuring the switch

You can install the switch in either of two ways:

v As a stand-alone unit on a flat surface

v In an Electronic Industries Association (EIA) cabinet using a slide-rail rack mount

kit, which is provided with the switch. When you mount the switch into a slide-railrack, you can mount the chassis to slide from either the port side or the non-portside.

The SAN24B-4 can be configured and operated as either a SAN fabric switch or asan Access Gateway. The configuration instructions in this publication are for theSAN24B-4 to operate as a switch. The installation instructions in this documentapply to both Switch and Access Gateway modes. To configure and operate theSAN24B-4 in Access Gateway mode, refer to the IBM System Storage SAN24B-4Access Gateway Quick Start Guideand the Access Gateway Administrator's Guide.

Attention: When you enable Access Gateway mode, you disable the ability forthe SAN24B-4 to operate as a switch. Access Gateway mode and switch mode are

mutually exclusive. If you want to use the SAN24B-4 as a switch at a later time, youwill need to disable Access Gateway mode and enable switch mode. Changingbetween Access Gateway and Switch modes is a data disruptive operation. It isstrongly recommended that you disable the switch from the command line interfacebefore enabling or disabling Access Gateway mode.

Installation and safety considerations

Use this section to prepare your site for a safe and successful installation.

Attention: Although the switch has been designed for customer installation andreplacement procedures, you must first ensure that the rack into which the switch isto be installed is also customer accessible. If it is not, then only trained personnel

can install and service these switches in such a rack.

Attention: Read the Safety and environmental notices on page ixbefore attempting any installation or maintenance procedures.

The switch can be installed either as a free-standing unit, or installed in an EIAcabinet, using an optional slide-rail rack mount kit. When mounting into a slide-railrack, you can mount the chassis to slide from either the port side or the nonportside.

Electrical considerationsTo install and operate the switch successfully, ensure the following:

v The primary outlet is correctly wired, protected by a circuit breaker, and groundedin accordance with local electrical codes.

v The supply circuit, line fusing, and wire size are adequate, as specified by theelectrical rating on the switch nameplate.

v The power supply standards provided in Power supply specifications on page34 are met.

Environment considerationsFor successful installation and operation of the switch, ensure that the followingenvironmental requirements are met:

v At a minimum, adequate cooling requires that you install the switch with thenonport side, which contains the air intake vents, facing the cool-air aisle.

v All equipment in the rack should force air in the same direction to avoid intakingexhaust air.

v A minimum of 680 l/min (24 cubic ft/min) of air flow is available to the air intakevents on the nonport side of the switch.

v The ambient air temperature does not exceed 40 C (104 F) while the switch isoperating.

Cabinet considerations

Attention: See Rack safety on page xiv for danger and caution notices relatedto product installations in racks or cabinets.

For successful installation and operation of the switch in a cabinet, ensure that thefollowing cabinet requirements are met:

v The cabinet must be a standard EIA cabinet.

v Plan a cabinet space that is 1 rack unit 4.45 cm (1.75 in.) high, 48.3 cm (19 in)wide.



31/75

v Ground all equipment in the cabinet through a reliable branch circuit connectionand maintain ground at all times. Do not rely on a secondary connection to abranch circuit, such as a power strip.

v Ensure that airflow and temperature requirements are met on an ongoing basis,particularly if the switch is installed in a closed or multicabinet assembly.

v Verify that the additional weight of the switch does not exceed the cabinetsweight limits or unbalance the cabinet in any way.

v Secure the cabinet to ensure stability in case of unexpected movement, such asan earthquake.

Installing a stand-alone switch

To install the switch as a stand-alone unit, use the following procedure:

1. Unpack the switch and verify the items listed in Items included with the switchon page 5

2. Apply the adhesive rubber feet. Applying the rubber feet onto the switch helpsprevent the switch from sliding off the supporting surface.

a. Clean the indentations at each corner of the bottom of the switch to ensure

that they are free of dust or other debris that might lessen the adhesion ofthe feet.

b. With the adhesive side against the chassis, place one rubber foot in eachindentation and press into place.

3. Place the switch on a flat, sturdy surface.

4. Provide power to the switch as described in Powering the switch on and off onpage 19.

Attention: Do not connect the switch to the network until the IP address iscorrectly set. For instructions on how to set the IP address, see Configuring theswitch on page 14.

Installing the switch into an EIA cabinet

Attention: Although the switch has been designed for customer installation andreplacement procedures, you must first ensure that the rack into which the switch isto be installed is also customer accessible. If it is not, then only trained personnelcan install and service these switches in such a rack.

Attention: Read the Safety and environmental notices on page ixbefore attempting any installation or maintenance procedures.

Attention: Refer to Rack safety on page xiv for danger and caution notices

related to rack and cabinet installations.

You can install the rack mount kit in either of two ways:

v To allow the port side of the switch to slide out of the exhaust-air side of thecabinet. In this installation, the port side of the switch is flush with the edge of thecabinet.

v To allow the non-port side of the switch to slide out the cool-air side of thecabinet. In this installation, the port side of the switch is set 7.62 cm (3 in.) backfrom the edge of the cabinet, allowing a more gradual bend in the fiber opticcables.

Cables can be organized and managed in a variety of ways: for example, usingcable channels on the sides of the cabinet or patch panels to minimize cablemanagement. Following is a list of recommendations:

v Plan for rack space required for cable management before installing the switch.

v Leave at least 1 meter (3.28 ft) of slack for each port cable. This provides roomto remove and replace the switch, allows for inadvertent movement of the rack,and helps prevent the cables from being bent to less than the minimum bendradius.

v If you are using Brocade ISL Trunking, consider grouping cables by trunkinggroups. The cables used in trunking groups must meet specific requirements, asdescribed in the Fabric OS Administrators Guide.

v For easier maintenance, label the fiber optic cables and record the devices towhich they are connected.

v Keep LEDs visible by routing port cables and other cables away from the LEDs.

v Use hook-and-loop fasteners to secure and organize fibre optic cables. Do notuse tie wraps on fiber optic cables, because wraps are easily overtightened andcan damage the optic fibers.

Configuring the switchYou must configure the switch to ensure correct operation within a network andfabric. For instructions about how to configure the switch to operate in a fabric thatcontains switches from other vendors, refer to the Fabric OS Administrator's Guide.

For more information about the commands used in this procedure, refer to theFabric OS Command Reference Manual.

v Providing power to the switch

v Creating a serial connection on page 15

v Setting the switch IP address on page 15

v Setting the date and time on page 16

Using the EZSwitch setup (optional)Once you have set up the switch in a rack or as a stand-alone switch, it is time togive it power and a basic configuration. If you are going to use the switch in asingle-switch setup, you can use EZSwitchSetup to complete the basicconfiguration. See the EZSwitchSetup CD included with the accessory kit for moreinformation. You can also use the SAN24B-4 Quick Start Guide. If you do not wantto use EZSwitch Setup, use the instructions in following sections.

Providing power to the switch

To provide power to the switch:1. Connect the power cord to the power receptacle on the port side of the switch,and then to the power source. Ensure that the cord has a minimum service loopof 15 cm (6 in.) available and is routed to avoid stress.The switch does not have a on/off power switch. This means that power issupplied to the switch as soon as you connect it to an AC power source.The status LEDs display amber until POST is complete, and then change togreen. The switch usually requires from 1 to 3 minutes to boot and completePOST.

2. After POST is complete, verify that the switch power and status LEDs on the leftof the port side of the switch are green.



39/75

Creating a serial connectionYou will perform all basic configuration tasks in this guide using a serial connection.To create a serial connection to the switch, complete the following steps:

1. Connect the serial cable to the serial port on the switch and to an RS-232 serialport on the workstation.If the serial port on the workstation is RJ-45 instead of RS-232, remove the

adapter on the end of the serial cable and insert the exposed RJ-45 connectorinto the RJ-45 serial port on the workstation.

2. Disable any serial communication programs running on the workstation.

3. Open a terminal emulator application (such as HyperTerminal on a PC, orTERM, TIP, or Kermit in a UNIX environment), and configure the application asfollows:

v In a Windows environment:

Bits per second 9600

Databits 8

Parity None

Stop bits 1Flow control None

v In a UNIX environment, type the following string at the prompt:

tip /dev/ttyb -9600If ttyb is already in use, use ttya instead and enter the following string at theprompt:

tip /dev/ttya -9600

Setting the switch IP addressYou can configure the switch with a static IP address, or you can use a DHCP(Dynamic Host Configuration Protocol) server to set the IP address of the switch.

DHCP is enabled by default. The switch supports both IPv4 and IPv6.Using DHCPWhen using DHCP, the switch obtains its IP address, subnet mask, and defaultgateway address from the DHCP server. The DHCP client can only connect to the aDHCP server that is on the same subnet as the switch. If your DHCP server is noton the same subnet as the switch, use a static IP address.

Setting a static IP address1. Log into the switch using the default password, which is password.

2. Use the ipaddrset command to set the Ethernet IP address.If you are going to use an IPv4 IP address, enter the IP address in dotteddecimal notation as prompted.

Ethernet IP Address: [192.168.74.102]

If you are going to use an IPv6 address, enter the network information insemicolon-separated notation as prompted.

switch:admin> ipaddrset -ipv6 --add 1080::8:800:200C:417A/64IP address is being changed...Done.

3. Complete the rest of the network information as prompted.

Ethernet Subnetmask: [255.255.255.0]Ethernet IP Address: [192.168.74.102]

Ethernet Subnetmask: [255.255.255.0]

4. Enter off to Disable DHCP when prompted.

DHCP [OFF]: off

Setting the date and timeThe switch maintains the current date and time inside a battery-backed real-timeclock (RTC) circuit. Date and time are used for logging events. Switch operationdoes not depend on the date and time; a switch with an incorrect date and timevalue still functions properly. However, because the date and time are used forlogging, error detection, and troubleshooting, you should set them correctly.

Setting the date1. If you are not already logged into the switch; do so now using the default

password, which is password.

2. Enter the date command, using the following syntax:

date "mmddHHMMyy"

The values represent the following:

v mm is the month; valid values are 01 through 12

v dd is the date; valid values are 01 through 31

v HH is the hour; valid values are 00 through 23

v MM is minutes; valid values are 00 through 59

v yy is the year; valid values are 00 through 99 (values greater than 69 areinterpreted as 1970 through 1999, and values less than 70 are interpreted as2000-2069)

switch:admin> date

Fri Sep 29 17:01:48 UTC 2007switch:admin> date "0927123007"Thu Sep 27 12:30:00 UTC 2007switch:admin>

Setting time zonesYou can set the time zone for a switch by name. You can specify the setting usingcountry and city or time zone parameters.If the time zone is not set with the new options, the switch retains the offset timezone settings. The tsTimeZone command also includes an option to revert to theprior time zone format. For more information about the tstimezone [--old] option,see the Fabric OS Command Reference Manual.

You can set the time zone for a switch using the tsTimeZone command. ThetsTimeZone command allows you to perform the following tasks:

v Display all of the time zones supported in the firmware

v Set the time zone based on a country and city combination or based on a timezone ID such as PST

The time zone setting has the following characteristics:

v You can view the time zone settings. However, only those with administrativepermissions can set the time zones.

v The tsTimeZone setting automatically adjusts for Daylight Savings Time.



41/75

v Changing the time zone on a switch updates the local time zone setup and isreflected in local time calculations.

v By default, all switches are in the GMT time zone (0,0). If all switches in a fabricare in one time zone, it is possible for you to keep the time zone setup at thedefault setting.

v System services that have already started will reflect the time zone changes onlyafter the next reboot.

v Time zone settings persist across failover for high availability.

The following procedure describes how to set the time zone for a switch. You mustperform the procedure on allswitches for which the time zone must be set.However, you only need to set the time zone once on each switch, because thevalue is written to nonvolatile memory.

1. If you are not already logged into the switch; do so now using the defaultpassword, which is password.

2. Enter the tsTimeZone command as follows:

switch:admin> tstimezone [--interactive]/ [, timezone_fmt]

Use timezone_fmt to set the time zone by Country/City or by time zone ID,such as PST.The following example shows how to display the current time zone setup andhow to change the time zone to US/Central.

switch:admin> tstimezoneTime Zone : US/Pacificswitch:admin> tstimezone US/Centralswitch:admin> tstimezoneTime Zone : US/Central

The following procedure describes how to set the current time zone usinginteractive mode to Pacific Standard Time.

1. Type the tsTimeZone command as follows:

switch:admin> tstimezone --interactive

2. You are prompted to select a general location.

Please identify a location so that time zone rules can be set correctly.

3. Enter the appropriate number or Ctrl-D to quit.

4. At the prompt, select a country location.

5. At the prompt, enter the appropriate number to specify the time zone region orCtrl-D to quit.

Synchronizing local time using NTPYou can synchronize the local time of the principal or primary fabric configuration

server (FCS) switch to a maximum of eight external network time protocol (NTP)servers. To keep the time in your SAN current, it is recommended that the principalor primary FCS switch has its time synchronized with at least one external NTPserver. The other switches in the fabric will automatically take their time from theprincipal or primary FCS switch.

All switches in the fabric maintain the current clock server value in non-volatilememory. By default, this value is the local clock server of the principal orprimary FCS switch. Changes to the clock server value on the principal or primaryFCS switch are propagated to all switches in the fabric.



42/75

For more information on using an NTP server, and IPv6 considerations, see theFabric OS Administrators Guide.

1. If you are not already logged into the switch; do so now using the defaultpassword, which is password.

2. Enter the tsClockServer command:

switch:admin> tsclockserver ""

where ntp1 is the IP address or DNS name of the first NTP server, which theswitch must be able to access. The second ntp2 is the second NTP server andis optional. The operand is optional; by default, this value isLOCL, which uses the local clock of the principal or primary switch as the clockserver.

The tsClockServer command accepts multiple server addresses in either IPv4, IPv6,or DNS name formats. When multiple NTP server addresses are passed,tsclockserver sets the first obtainable address as the active NTP server. The restwill be stored as backup servers that can take over if the active NTP server fails.The principal or primary FCS switch synchronizes its time with the NTP serverevery 64 seconds.

switch:admin> tsclockserverLOCLswitch:admin> tsclockserver "132.163.135.131"switch:admin> tsclockserver132.163.135.131switch:admin>

The following example shows how to set up more than one NTP server using aDNS name:

switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net"Updating Clock Server configuration...done.

Updated with the NTP serversChanges to the clock server value on the principal or primary FCS switchare propagated to all switches in the fabric.

Powering the switch on and off

See Chapter 2, Installing and configuring the switch, on page 5 for initial setup

instructions before powering the switch on for the first time. Once the switch hasbeen properly configured, follow these instructions to power the switch on and off.

The SAN24B-4 does not have an AC power switch. To power on the SAN24B-4,connect the power cable to the AC receptacle on the switch and to a power source.The switch runs POST by default each time it is powered on, reset, or rebooted,and requires a minimum of three minutes to run. To end the flow of power to theswitch, remove the power cord from the power source.

Interpreting LED activity

System activity and status can be determined through the activity of the LEDs onthe switch. All LEDs are located on the port side of the switch. There are three

possible LED states: no light, a steady light, and a flashing light. The steady lightsand flashing lights can be green or amber. The LEDs flash either of these colorsduring boot, POST, or other diagnostic tests. This is normal and does not indicate aproblem unless the LEDs do not indicate a healthy state after all boot processesand diagnostic tests are complete.

The switch has the following LEDs:

v System power LEDOne LED (green) to indicate system power

v System status LEDOne LED (green/amber) to indicate system status

v Ethernet status LEDsTwo LEDs to indicate speed and link status

v Port status LEDs24 LEDs (green/amber) to indicate status for each port

POST and boot specifications

When the switch is turned on or rebooted, the switch performs POST. Total boottime with POST is up to 3 minutes. POST can be omitted after subsequent rebootsby using the fastboot command or entering the diagDisablePost command topersistently disable POST.

For more information about these commands, refer to the Fabric OS CommandReference Manual.

POSTThe success or failure results of the diagnostic tests that run during POST can bemonitored through the error log or the command line interface.

POST includes the following steps:1. Preliminary POST diagnostics are run.

2. Operating system is initialized.

3. Hardware is initialized.

4. Diagnostic tests are run on several functions, including circuitry, portfunctionality, memory, statistics counters, and serialization.

BootIn addition to POST, boot includes the following steps after POST is complete:

1. Universal port configuration is performed.

2. Links are initialized.

3. Fabric is analyzed, and if any ports are connected to other switches, the switchparticipates in a fabric configuration.

4. Switch obtains a domain ID and assigns port addresses.

5. Unicast routing tables are constructed.

6. Normal port operation is enabled.



48/75

Interpreting POST results

POST is a system check that is performed each time the switch is powered on,rebooted, or reset. During POST, the LEDs flash amber and green. Any errors thatoccur during POST are listed in the error log.

To determine that POST completed successfully and whether or not any errors were

detected:1. Verify that the switch LEDs indicate that all components are healthy. See

Table 4 on page 21 through Table 7 on page 23 for the description andinterpretation of LED patterns. If one or more LEDs do not display a healthystate, verify that the LEDs on the switch are not set to beacon; use theswitchShow command to detect if beaconing is active.

2. Verify that the switch prompt displays on the terminal of a computer workstationconnected to the switch. If there is no switch prompt when POST completes,press Enter. If the switch prompt still does not display, try opening anothertelnet session or accessing through another management tool. If this is notsuccessful, the switch did not successfully complete POST; contact IBM Servicefor repair.

3. Review the switch system log for errors. Any errors detected during POST arewritten to the system log, which is accessible through the errShow command.

For information about all referenced commands, and on accessing the error log,refer to Fabric OS Administrators Guide. For information about error messages,refer to the Fabric OS System Error Message Reference Manual.

Switch FRU units

The only parts for this switch that are field replaceable are the SFPs. The entireswitch is a FRU. The fan units and power supply are not field replaceable in thisswitch.

Maintaining the switch

The switch does not require any regular physical maintenance; it was designed tominimize the chance of failure. Ensure that the environmental conditions, describedin Environment considerations on page 6, are met. This helps prevent failure ofthe switch due to distress or abuse.

Installing SFPsThe switch only supports Brocade-branded SFPs. If you use an unqualified SFP,the switchShow command output will show the port in an Mod_Inv state. FabricOS will also log the issue in the system error log.

Follow these instructions to install an SFP:1. Making sure that the bail (wire handle)B is in the unlocked position, place the

SFP in the correctly oriented position on the port, as shown in Figure 9 on page25

Note: Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom.The correct position to insert an SFP into the upper row of ports is withthe gold edge down. The correct position to insert an SFP into the lowerrow of ports is with the gold edge up.

2. Slide the SFP into the port until you feel it click into place; then close the bail.
