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.

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

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.

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.

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.)

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)

Huawei Technologies Proprietary
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.

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.
If the specified application file does not exist, the switch will automatically choose an
existing valid application file to boot.
5.2.3 Setting the Attribute of a File
You can set the attribute of a file from the Boot menu.
The following takes an application file for example to describe the required steps:
I. Enter the Boot menu and input 2 to select “2. Select application file to boot”
and enter the corresponding submenu.
1. Download application file to flash
2. Select application file to boot
3. Display all files in flash
4. Delete file from flash
5. Modify bootrom password
6. Enter bootrom upgrade menu
7. Skip current configuration file
8. Set bootrom password recovery
9. Set switch startup mode
0. Reboot
Enter your choice(0-9):2
Select application file to boot
1. set application files
2. set configuration files
3. set web files
0. return
Enter your choice(0-3):1
II. Set the attributes of application, configuration, or Web files as needed. In
this example, enter 1 to select “1. set application files”.

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.
II. Loading BootROM
Follow these steps to download the Boot ROM program:
Step 1: Enter <6> or <Ctrl + U> in the Boot Menu to access the Boot ROM loading

In case of inadequate Flash memory space, you can delete some of the program
files in Flash, those that are no longer in use for example, after completing Boot
ROM loading. Then FTP the host program to the switch.
5.4.2 Loading Software Remotely Using TFTP
TFTP is similar to FTP in remote software downloading. But with TFTP, the switch can
only be used as the client to download software to its Flash Memory from the TFTP
server. After that, the remaining steps are the same as remote loading using FTP.

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.

6.3 Dealing with Power System Failures
You can know whether the power system has failed by reading the PWR LED on the
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.

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.

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.

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.
