Note:

The S3928P-PWR-EI/S3952P-PWR-EI provides overtemperature protection

mechanism which enables the switch to shut down the PoE function on all the ports

when the internal temperature is over 65°C (149°F). The switch restores the PoE

function on all the ports when the temperature falls below 60°C (140°F).

The S3928P-PWR-EI/S3952P-PWR-EI can only use PoE external power supply

recommended by Huawei-3Com as the DC-input, otherwise, the device can be

damaged.

Installation ManualQuidway S3900 Series Ethernet Switches Chapter 2 Preparing for Installation


2-1

Chapter 2 Preparing for Installation

2.1 Safety Precautions

To avoid any device impairment and bodily injury caused by improper use, observe

these rules:

Before cleaning the switch, unplug the power plug of the switch first. Do not clean

the switch with wet cloth or liquid.

Do not place the switch near water or any damp area. Prevent water or moisture

from entering the switch chassis.

Do not place the switch on an unstable case or desk. The switch might bedamaged severely in case of a fall.

Ensure proper ventilation of the equipment room and keep the ventilation vents of

the switch free of obstruction.

Make sure that the operating voltage is the same one labeled on the switch.

Do not open the chassis while the switch is operating or when electrical hazards

are present to avoid electrical shocks.

When replacing interface cards, wear ESD-protective gloves to avoid damaging

the cards.

2.2 Installation Site

The S3900 series must be used indoors. You can mount your switch in a rack or on a

tabletop/workbench, but make sure:

Adequate clearance is reserved at the air inlet/exhaust vents for ventilation.

The rack or table/workbench has a good ventilation system.

The rack is sturdy enough to support the device and its accessories.

The rack or table/workbench is well earthed.

To ensure normal operation and long service life of your VG, install it in an environment

that meets the requirements described in the following subsections.

2.2.1 Temperature/Humidity

You must maintain a proper temperature and humidity in the equipment room.

Long-term high humidity may lead to bad insulation, electricity leakage, mechanical

property changes, and corrosion. However, if the relative humidity is two low, captive

screws may become loose as the result of contraction of insulation washers and static

electricity may be produced in a dry environment to jeopardize the CMOS circuits on

the device. High temperature is the most undesirable condition, because it accelerates





2-2

aging of insulation materials and can thus significantly lower reliability and service life

of your switch.

2.2.2 Cleanness

Dust is a hazard to the operating safety of your device. The dust accumulated on the

chassis can be adsorbed by static electricity and result in poor contact of metal

connectors or metal contact points. This can not only shorten the service life of your

device but also cause communications failures. When the relative indoor humidity is

low, electrostatic adsorption is more likely to happen. The contents of the dust must be

limited as shown in Table 2-1:

Table 2-1 Dust content limits in an equipment room

Substance Unit Content

Dust Particles/m³

≤ 3 X 104

(No visible dust on the tabletop forthree days)

Remark: the diameter of a dust particle ≥ 5µm

Besides dust, there are rigorous limits on the harmful gases that can accelerate the

erosion and aging of metals, such as salts, acids, and sulfides, as shown in Table 2-2.

Table 2-2 Harmful gas limits in the equipment room

Gas Maximum (mg/m3)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

2.2.3 Electromagnetic Susceptibility

The operation of your switch can be affected by external interferences, such as

conducted emission by capacitance coupling, inductance coupling, electromagnetic

wave radiation, and common impedance (including the grounding system) coupling,

and leads (power cords, signaling cables and output wires. To eliminate the

interferences, make sure to:

For the AC power supply that adopts TN system, use a monophase three-line

power socket with Protection Earth (PE) to effectively filter interference from the

power grid.





2-3

Keep the device far from radio transmitting stations, radar stations, and

high-frequency devices.

Use electromagnetic shielding when necessary, for example, use shielded

interface cables. Route interface cables only indoors to prevent signal ports from getting damaged

by overvoltage or overcurrent caused by lightning strikes.

2.2.4 Laser Safety

The S3900 series are class-1 laser devices.

If the extended optical boards on your switch are operating, do not stare into the optical

ports because the laser light emitted by the optical fiber can hurt your retina.

Caution:

Staring into the laser beam produced by the fiber can hurt your eyes.

2.3 Installation Tools

Flat-blade screwdriver

Phillips screwdriver

ESD-preventive wrist strap

Caution:

The installation tools are not provided with the S3900 series.

Chapter 3 Installing the Switch

Caution:

When you ask your sales agent to maintain the switch, you must ensure that the

dismantlement-preventive seal on a mounting screw of the switch chassis is intact. If

you want to open the chassis, you should contact the agent for permission. Otherwise,

you will bear any consequence resulted from your actions without permission.

3.1 Mounting the Switch in a Rack or on a Tabletop

3.1.1 Rack-Mounting the Switch

Follow these steps to mount your switch in a standard 19-inch rack, as shown in Figure

3-1:

Step 1: Check that the rack is sturdy and properly earthed. Attach the rack-mount

brackets to the front or rear of the chassis with screws.

Step 2: Place the device on a shelf in the rack and slide it to a proper position along the

guide rails, reserving a suitable clearance between the device and the guide rails.

Step 3: Fix the brackets to the rack posts with screws, making sure that the device is

securely fixed.

Figure 3-1 Installing the switch in a 19-inch rack





3-2

Note:

The mounting brackets are used for fixing rather than weight bearing. In a 19-inch

standard rack, the weight of the switch is supported by the shelf beneath it.

3.1.2 Mounting the Switch on a Tabletop/Workbench

When placing the switch on a tabletop or workbench, you simply need to:

Make sure that the tabletop or workbench is clean, flat, and sturdy.

Allow 10 cm (3.9 in.) of clearance around the sides of the chassis.

Do not place heavy objects on the switch.

3.2 Connecting the Power Cord and the Ground Wire

3.2.1 Connecting the AC-Input Power Cord

I. AC-input power socket (recommended)

You are recommended to use a monophase three-line power socket with a ground

contact or a general purpose PC power socket, making sure that the power point is well

connected to building ground. Normally, the ground point of the power source in a

building was buried in the ground during the construction and wiring. Still, you must

make sure of that.

Figure 3-2 Power socket (recommended)

II. Connecting the AC-input power cord

Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear

of the chassis and the other end to the ground as near as possible.

Step 2: Connect one end of the power cord to the power socket on the rear of the

chassis, and plug the other end to the AC power jack of the power source.

Step 3: Check that the PWR LED on the front panel of the switch is ON.

3.2.3 Connecting the Ground Wire

Caution:

Correctly connecting the switch ground wire is crucial to the lightning protection and

electromagnetic susceptibility (EMS) of a switch.





3-5

The power input end of the switch is connected with a noise filter, whose central ground

is directly connected to the chassis, forming the chassis ground (commonly known as

PGND). This chassis ground must be securely connected to the earth ground so that

the faradism and leakage electricity can be safely released to the ground, enhancingthe EMS capability of the switch.

Ground your switch as follows:

When a grounding strip is available at the installation site, attach one end of the

yellow/green ground wire of the switch to the grounding screw on the grounding

strip and fasten the captive nut. (Note that the fire main and lightning rod of a

building are not suitable for grounding the switch. The ground wire of the switch

should be connected to the grounding device for the equipment room.)

3.3.2 Connecting the Console Cable

Follow these steps to connect a terminal device, a PC for example, to the switch:

Step 1: Plug the DB-9 (female) connector of the Console cable to the serial port of thePC where the switch is to be configured.

Step 2: Connect the RJ-45 connector of the console cable to the Console port of the

switch.

Caution:

Read the mark for the port to be connected carefully to make sure it is the right port.

Note:

The serial ports on PCs do not support hot swapping. Therefore, do not insert or

remove a serial interface cable from a PC that is connected to a switch with power. In

connecting a PC to the switch, first connect the DB-9 connector of the console cable to

the PC and then the RJ-45 connector to the switch. In disconnecting them, remove the

RJ-45 connector prior to the DB-9 connector.

3.4 Verifying Installation

The correct power source is used.

The ground wire is securely connected.

Both of the console cable and power cord are correctly connected.

All the interface cables are routed indoors. If there are cables outdoors, check that

the socket strip with lightning protection and lightning arresters for network ports

have been correctly connected.

Installation ManualQuidway S3900 Series Ethernet Switches Chapter 5 Loading Boot ROM and Host Software


5-1

Chapter 5 Loading Boot ROM and Host Software

Switch software loading through serial ports in the past is time consuming and cannot

be operated remotely. To address these problems, TFTP and FTP are used to allow

software and file downloading through Ethernet ports. The following subsections

describe how to load software and files in these two approaches.

5.1 Introduction to Loading Approaches

To load software remotely, use FTP or TFTP.

To load software at the local, use XModem at the Console port or TFTP/FTP at an

Ethernet port.

Note:

Ensure that the Boot ROM and host software versions that you download can work with

each other.

5.2 File attribute in Boot ROM

5.2.1 Introduction to File Attribute

In Boot ROM, application files, configuration files, and Web files support three kinds of

attributes: main, backup, and none, which are described in Table 5-1.

Table 5-1 File Attribute

Attribute Usage Feature Identification

mainIndicates the main bootfile, which is used by adevice to boot.

Only one application

file, one configurationfile, and one Web file inthe Flash can have themain attribute.

(*)

backup

Indicates a boot file withthe backup attribute.When a device cannotboot with the main bootfile, it will use the backupboot file to boot.

Only one applicationfile, one configurationfile, and one Web file inthe Flash can have thebackup attribute.

(b)





5-2

Attribute Usage Feature Identification

noneIndicates a file havingneither the main attributenor the backup attribute.

-No specialidentification

Note:

The suffixes of application, configuration, and Web files are app, cfg, and web

respectively.

A file can have both the main attribute and the backup attribute. Such a file is

displayed with identification of (*b).

If you specify a file to have the main attribute when there is already a main boot file, the

original main boot file will lose the main attribute, ensuring that only one application file,

one configuration file, and one web file in the Flash have the main attribute. The same

is true for the backup attribute.

Operations of a file are separate from those of the attributes. For example, when you

delete a main boot file from the Flash, the main attribute of the file remains. If you

download a valid file with the same name to the Flash, the new file will have the main

attribute.

The file attribute feature is backward compatible. When you upgrade the Boot ROM of a

device, the original default app boot file has the main attribute.

5.2.2 Impact of File Attributes on Downloading and Booting

I. Downloading

When you download an application, configuration, or Web file from the boot menu

through TFTP or FTP, the device identifies the file by its suffix and checks the validity of

the file if it is an app file. Then, the device displays a message for you to confirm if you

want to set it as a boot file. You can set file attributes at prompt.

Note:

If a downloaded file has the same name as that of an existing file in the Flash, the new

file will overwrite the original one, while having the same attributes.





5-3

II. Booting

When a device boots, it first uses the application file with the main attribute. If the boot

operation fails, the device selects the application file with the backup attribute to try

again. If the boot operation fails again, the device displays an error message and

repeats the above procedure.

Note:

If the device boots failed with an application file with main attribute, it will display an

alert message.

5.3.2 Loading Software from Console Port Using XModem

I. Introduction to XModem

XModem is a file transfer protocol widely used for its simplicity and good performance.

XModem transfers files through the Console port, supporting data packets of 128 bytes

and 1 KB. With respect to reliability, it supports checksum, CRC, and the error packet

retransmission mechanism. Normally, the maximum number of retransmission

attempts is ten.

XModem transfer is completed by receiving and sending programs together. Receiving

program initiates packet checking method negotiation by sending the negotiationcharacter. If negotiation passes, the sending program starts packet transfer. Upon

receipt of a complete packet, the receiving program checks it using the agreed-upon

check method. If the check succeeds, the receiving program sends an

acknowledgement character; if the check fails, it sends a reject character. Upon receipt

of the acknowledgement, the sending program continues to send the next packet; upon

receipt of the reject, it retransmits the packet.

Chapter 6 Maintenance and Troubleshooting

6.1 Dealing with Loading Failures

If software loading fails, the system operates with the original version.

To address the failure cause, take these steps:

1) Check that the physical ports are correctly and securely connected. If they are not,

reconnect them correctly and restart loading.

2) Check information about the loading procedures for input errors on the

HyperTerminal.

If XModem is used, check that you have reset the baud rate of the HyperTerminalto 9600 bps after loading the software with another baud rate.

If TFTP is used, check that you have correctly specified the TFTP parameters:

server and switch IP addresses; name of the software to be loaded; and path for

the TFTP server to operate on program files.

If FTP is used, check that you have correctly specified the FTP parameters: server

and switch IP addresses; name of the software to be loaded; and username and

password.

3) Contact your sales agent for help if you cannot address the problem after taking

the preceding two steps.

6.2 Dealing with Password Loss

6.2.1 Dealing with User Password Loss

front panel. If the power system is operating normally, the PWR LED is ON. If not, check

that:

The switch power cord is correctly connected.

The power source can work with the switch.

6.4 Dealing with Configuration System Failures

If the switch is operating normally after it is powered up, it displays the start-up

information on the console terminal. If the configuration system has failed, it displays

illegible characters or nothing at all.

I. No information on the terminal

Take these steps to address the problem:

1) Check that: The power system is operating normally.

The console cable is connected correctly.

2) Check that the console cable is in good condition and the terminal (HyperTerminal

for example) parameter settings are correct.

II. Illegible characters on the terminal

Make sure you have set on your terminal (HyperTerminal):

Baud rate = 9600

Databit = 8

Parity check = none

Stopbit = 1

Flow control = none

Terminal emulation = VT100

Reconfigure the parameters if their values are different.



Installation ManualQuidway S3900 Series Ethernet Switches Appendix A Lightning Protection of the Switch


A-1

Appendix A Lightning Protection of the Switch

A.1 Installation of Lightning Arrester for AC Power (SocketStrip with Lightning Protection)

Caution:

Lightning arrester will not be shipped with the switch. You should purchase it by

yourself if needed.

If an outdoor AC power cord should be directly led to the switch, please serially connect

the lightning arrester for AC power (Socket Strip with Lightning Protection) before you

plug AC power cord into the switch, thus to prevent the possible damage to the switch

due to lightning strike. You can use cable clips and screws to fasten the lightning

arrester for AC power on the cabinet, workbench or the wall of equipment room.

Mainboard

Grounding and polarity indicator (red) :

On means that the lines are wrongly connected

(either the ground wire is not well connected, or the live and zero lines are wrongly connected).

Please check the power supply circuit.

Power switch

Normal operation indicator (green):

On means that the arrester works normally. Otherwise, itmeans that the protection circuit has been damaged.

Figure A-1 Diagram of lightning arrester





A-2

Caution:

Make sure that the arrester is well grounded before using the lightning arrester for

power.

After inserting AC power cord plug of switch into the socket of lightning arrester, if

the green LED is on and the red LED does not alarm, it means that the lightning

arrester of power is running and the function of lightning protection has taken effect.

Pay adequate attention if the red LED is on. You should correctly locate the problem,

whether it is caused because the ground wire of the arrester is not well grounded or

because the live and zero wires are connected in reverse direction. You may check

that in the following way. When the red LED is on, use a multimeter to examine

polarity at the power socket of the arrester. If it is same to that of the power socket in

the equipment room, it means that arrester is not well grounded. If it is adverse tothat of the power socket in the equipment room, it means that the power socket of

the arrester is set to the reverse polarity. In this case, you should open the power

socket of arrester to correct polarity. After that, if the red LED still alarms, it means

that the arrester is not well grounded yet.

A.2 Installation of Lightning Arrester for Network Port

Note:

Lightning arrester for network port is specially designed for the Ethernet port of

10/100M electrical interface (RJ-45 connector is adopted in this case).

Caution:

Lightning arrester for network port will not be provided along with the switch, and you

should purchase it by yourself if needed.

If an outdoor network cable should be led to the switch, please serially connect the

lightning arrester for network port before you plug this cable into the interface on the

switch, in case of the possibility that the switch may be damaged due to lightning strike.

I. Required tools

Phillips screwdriver or Flat-blade screwdriver





A-3

Multimeter

Tilted wire cutter

II. Installation procedure

Step 1: Tear the protection paper at one side of the double faced adhesive tape apart

from the tape, and stick the tape on the surface of the arrester. Tear the protection

paper at another side apart from the tape, and stick the arrester onto the chassis of the

switch. The arrester should be attached on the chassis as close to the grounding screw

as possible.

Step 2: According to the distance to the grounding screw of the switch, cut the ground

wire of the arrester, and securely tightening its ground wire to the grounding screw of

the switch.

Step 3: Use the multimeter to measure whether the ground wire of the arrester contactswell with the grounding screw of chassis.

Step 4: According to the instruction of arrester for network port, connect the arrester

with switch by the cables (be carefully with the cable direction. Outdoor network cable

should be inserted into the arrester‘s IN end, and the cable connected to the switch

should be inserted into the arrester’s OUT end). When you do that, observe whether

the arrester indicators normally display.

Note:

The instruction of lightning arrester for network port contains the technical

specifications, installation and maintenance guide of the arrester. Please carefully read

it before installing the arrester.

Step 5: Use the nylon ties to bundle the cables neatly.

III. Installation precautions

Fully consider the following items in the installation process, otherwise, the

performance of the lightning arrester for network port will be affected:

Lightning arrester for network port is installed in reverse direction. In practice, the

“IN” end should be connected to the outdoor network cable and the “OUT” end to

the network port on the switch.

Lightning arrester for the network port is not well grounded. The ground wire for

the arrester should be as short as possible, so to ensure its good contact with the

grounding screw of the switch. After the connection, use the multimeter to confirm

that.

The lightning arrester for the network port is not installed completely. If the switch

has more than one network ports to interconnect with other devices via cables

outdoor, you should install lightning arresters for all these network ports forprotection.
