Introduction
The MBUS is a service-independent maintenance and test bus. No service traffic
goes through the MBUS. The shutdown and reset of the MBUS does not affect the
services on the switch, and faults that have occurred on modules do not affect the
MBUS.
Through the MBUS, the system instructs the MBUS modules on individual cards to
power on/off the cards one by one in turn, thus prevent power surging. The MBUS
module software must support online upgrade.
16
CHAPTER 1: PRODUCT OVERVIEW
Role and function
The MBUS system is powered by 5 V from the MBUS on the fabric. The 5 V power
on the two fabrics are redundant to each other.
Each MBUS module is attached to the MBUS, which contains two control lines:
MBUS0 and MBUS1.
Each card has an independent MBUS module, those on the fabrics are primary
MBUS modules, and those on application modules are secondary MBUS modules.
When the fabrics operate in redundancy mode, the MBUS module on the active
fabric is the active module, and the one on the standby fabric is the standby
module.
The MBUS uses a controller area network (CAN) bus as its control bus, that uses
the 1:1 hot backup and transfers control information at 1 Mbps.
Fan Tray
■
The Switch 8807 uses one 25 W fan tray, which contains four 120 x 120 x 25.4
mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two
modes: fabric-controlled or temperature-controlled. They operate at -48 VDC
supplied from the backplane.
■
The Switch 8810 uses one 35 W fan tray, which contains six 120 x 120 x 25.4
mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two
modes: fabric-controlled or temperature-controlled. They operate at -48 VDC
supplied from the backplane.
■
The Switch 8814 uses two 25 W fan trays, each of which contains four 120 x
120 x 25.4 mm (4.7 x 4.7 x 1.0 in.) axial fan units (and totally eight for the two
fan trays). The fans can be governed in two modes: fabric-controlled or
temperature-controlled. They operate at -48 VDC supplied from the backplane.

■
Locate the emergency power-off switch in the room before installation. Shut
the power off at once in case accident occurs.
■
Unplug all the power cords and external cables before moving the chassis.
■
Do not maintain the equipment alone when it has been powered.
■
Never assume but check each time that power has been disconnected from a
circuit.
■
Do not place the switch on a moist area and avoid liquid flowing into the
switch.
The Switch 8800 Family are rather big and heavy, so follow the recommendations
below when moving it.
■
Remove all the external cables (including power cords) before moving the
chassis.
■
Do not move the switch alone. Work with another person.
■
Move the switch slowly and stably. Never move suddenly or twist your body.
■
Move the switch at stable and consistent paces with your peer. Keep balance of
your body.
CAUTION: You can only hold the handles at both sides of the chassis when
moving the switch, but not the plastic panel of the chassis, the handle of the fan
frame, the handle of the PSUs or the air vents of chassis.
As these parts are not designed for bearing the weight of the entire chassis, any
attempt trying to carry the switch with these parts may impair the switch and even
injure yourself.

CHAPTER 3: INSTALLATION PREPARATION
Wearing an
ESD-Preventive Wrist
Strap
To prevent the electronic components from being damaged by the electrostatic
discharge (ESD), take ESD measures for the area where the switch is located and
note the issues below:
■
Always wear an ESD-preventive wrist strap when installing the parts, especially
the electric printed circuit boards.
■
Hold the circuit board by the edge. Do not touch the components or the
electric printed circuit.
Take the following steps to use the ESD-preventive wrist strap.
Step 1: Wear the wrist strap on your wrist.
Step 2: Lock the wrist strap tight around your wrist to keep good contact with the
skin.
Step 3: Insert it into the hole peculiar to ESD-preventive wrist strap in the chassis
or attach it to the grounding screw of the chassis the alligator clips.
Step 4: Make sure that the ESD-preventive wrist strap is well grounded.
c
CAUTION: For the sake of safety, check the resistance of the ESD-preventive wrist
strap. The resistance reading should be in the range of 1 to 10 Mohm between
human body and the ground.
Safety
Recommendations
against Laser
Some I/O modules of the Switch 8800 Family have optical interfaces. In operating
status, it is dangerous to stare into the open optical interface because the laser
being transmitted through the optical fiber produces a small beam of light which
has very high power density and is invisible to human eyes; when a beam of light
enters the eye, retina may be burned.
c
CAUTION: The laser inside the optical fiber may hurt your eyes.
Examining Installation
Site
The Switch 8800 Family can only be used indoors. To ensure that the switch works
normally and to prolong its service lifetime, the following requirements should be
met in terms of installation environment.
Temperature/Humidity
Requirements
To ensure the normal operation and service lifetime of a switch, proper
temperature and humidity should be maintained in the equipment room.
Long-lasting high humidity in the equipment room is prone to poor insulation or
even leakage of the insulating material. Sometimes, the mechanical performance
deterioration, the rustiness and corrosion of some metal parts are also more likely
to occur. If the relative humidity is too low, the captive screws may become loose
due to the insulation washer contraction. Meanwhile, the electrostatic is likely to
be produced in the dry environment, which will jeopardize the CMOS circuit of the
switch. The higher the temperature, the greater the damage it will do to the
switch. Long-lasting high temperature will speed up the aging process of the
insulating materials, greatly lower the reliability of the switch, and therefore affect
its service life seriously.
Examining Installation Site
Cleanness Requirements
49
Dust is a hazard to the operating safety of the switch. The indoor dust
accumulated on the chassis can cause electrostatic absorption, which may result in
the poor contact of the connector or metal contact point. This happens more
frequently when indoor relative humidity is low, which will not only shorten the
service life of the switch, but also cause communication failure.
The required specifications on dust content and particle diameter in an equipment
room are shown in the following table.
Table 66 Limitation on dust content in equipment room
Mechanical active material
Unit
Content
Dust particle
particles/m3
‚≤3 x 104
(No visible dust on desk in three days)
Note: Dust particle diameter ‚≥ 5µm
Besides the dust specifications, the equipment room of the switch should also
meet the rigorous requirements for the content of salt, acid and sulfide in the air.
These harmful gases could accelerate the metal erosion and the aging process of
some parts. Incursion of harmful gases, such as SO2, H2S, NO2, NH3, and Cl2,
should be prevented. The specific limitation values of these harmful gases are
given in the following table.

Any possible interference sources, no matter outside or inside the system, affect
the switch in use in a way of capacitive coupling, inductive coupling,
electromagnetic radiation, common impedance (including the grounding system)
coupling or conducting line (power line, signaling line and transmission line etc.).
To prevent the interference, you should:
■
Take effective measures against electrical net interference for power supply
system.
■
Separate the working ground of the switch from the grounding device of the
power supply equipment or lightning-protection grounding device as far as
possible.
■
Keep the switch far away from the radio launcher, radar launcher, and
high-frequency devices working in the high current.
■
Adopt electromagnetic shielding if necessary.
A good grounding system is not only the basis essential to the stable and reliable
switch operation, but also an important guarantee of lightning protection,
anti-interference and ESD-prevention. The user must provide good grounding
system for the switch.

CAUTION: For the safety of operators and equipment, the switch must be well
grounded. The resistance reading between switch chassis and the ground must be
less than 1 ohm.
Common grounding environment
Step 1: Remove the screw from the grounding hole in the switch chassis.
Step 2: Wear the connector of the PGND wire accompanied with the switch on
the grounding screw.
Step 3: Insert the grounding screw into the grounding hole and screw it down.
Step 4: Connect the other end of the ground wire to the ground bar of the switch.
n
Generally, the cabinets installed in equipment rooms are equipped with ground
bar. In this case, you can connect the PGND wire of the switch to the ground bar
for it.
Other grounding environment
Following are some methods for grounding the switch in different grounding
environments that you are likely to encounter when installing the switch at
different places.
n
Rather than specifying the switch model or showing the actual location of the
switch power input or grounding screw, the following figures are primarily
intended for illustrating the switch grounding, either via grounding screw or
power input, in specific grounding environments.
■
If a ground bar is available, attach one end of the yellow-green PGND wire of
the switch to a grounding bolt of the ground bar and fasten the captive nuts.
Note that the fire main and lightning rod of a building are not suitable for
grounding the switch. The PGND wire of the switch should be connected to
the grounding device in the equipment room. (For the Switch 8800 Family, the
grounding screw is on the rear panel. Connect it as illustrated in Figure 37).

If there is no ground bar but earth nearby and the grounding body is allowed
to be buried, you can simply hammer an angle iron or steel pipe no shorter
than 0.5 m into the earth. In this case, the yellow-green PGND wire should be
welded with the angle iron (steel pipe) and the joint should be processed
against eroding. (For the Switch 8800 Family, the grounding screw is on the
rear panel. Connect it as illustrated in Figure 37).

Before connecting the fiber, make sure that the receive-end optical power does
not exceed the upper threshold of the receiving optical power. Excessive
receiving optical power is very likely to burn the optical module.
Fiber connectors are indispensable passive components in an optical fiber
communication system. Their application allows the removable connection
between optical channels, which makes the optical system debugging and
maintenance more convenient and the transit dispatching of the system more
flexible. Among various fiber connectors, only LC connector will be introduced
here.

Step 1: Plug one end of the fiber into the SFP optical module of the Switch 8800
Family.
Step 2: Connect the other end of the fiber into the corresponding device.
c
CAUTION: When the optical interface has not been connected with a fiber
connector or its dust-proof mesh is open, there might be some invisible radiation
emitted from the optical interface. So do not look into the optical interface
directly.
Cover the optical interface if there is no connector plugged in.
Cable Routing
Recommendations
Freestanding Switch on
Tabletop
Cabinet-Mounting
Switch
For only selling an integrated chassis, you do not have to care about the cabling
inside or outside the cabinet. All the I/O module cables are routed from the left
side of the chassis (along the cabling channel), and the chassis power cords
(AC/DC power cords) are routed in the front of the chassis.
If the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/O
module cables are bound on the cabling rack at the left side of the chassis and are
routed up or down to pass through the chassis top or the raised floor depending
on the available equipment room condition (that is, the signal cables are routed
into the chassis either from the cabling rack on the chassis top or from the cabling
trough under the floor) of the exchange office. The power cords run along the
left-front of the chassis and out of the chassis either from the top or the raised
floor depending on the equipment room conditions (DC power distribution
cabinet, lightning protection box, and terminal block, etc.) of the exchange office.
Cable Management
Cable Management
Requirements
■
Bundle and put the cables inside the cabinet in a straight and neat way. No
intertwinement or bending is allowed.
Cable Management
69
Figure 51 Cable bundling example I
Intertwined
Bent
■
The bending radius of cable body cannot be less than twice of the cable
diameter. The bending radius of the cable cannot be less than 5 times of its
diameter at the place where it is led out of the connector;
■
Different cables (power cord, signal cable, PGND wire, etc.) should be cabled
and bundled separately rather than together in the cabinet. If they are close to
each other, you can cable them in cross-shape. For parallel cabling, the space
between power cord and signal cable should be no less than 30 mm (1.2 in);
■
The cable binding rack and cabling channel inside and outside the cabinet
should be smooth and without sharp edges or tips;
■
The metal cable management hole should have a smooth and fully rounded
surface or wear a insulating bush;
■
Use the right type of ties to bundle the cables. Do not bundle cables with
joined ties. 3Com Corporation provides the following types of ties: 100 x 2.5
mm (3.9 in x 0.1 in), 150 x 3.6 mm (5.9 x 0.1 in), 300 x 3.6 mm (11.8 x 0.1 in),
530 x 9 mm (20.9 x 0.4 in), and 580 x 13 mm (22.8 x 0.5 in);
■
Cut the extra parts of the ties neatly after bundling the cables, leaving no sharp
or angular tips. See the following figure:
Figure 52 Cable bundling example II
70
CHAPTER 4: SWITCH INSTALLATION
■
Bundle the cables wherever cable bending cannot be avoided. However, the
cable ties cannot be placed inside the bending area in case of the likelihood of
cable core break due to excessive stress. See the following figure.
Figure 53 Cable bundling example III
■
The spare cables or excessive cable parts should be folded and bundled and
placed at a right place in the cabinet or on the cabling channel. A “right place”
refers to the place where the cables will not affect the operation of the device
or impair the device, or be damaged;
■
The power cords cannot be tied on the guides of any mobile components;
■
Reserve some redundancy for the cables connecting to the mobile parts, the
PGND wire of the door for example, to free the cables from possible stress.
Such a mobile part should be installed in such a way that the extra cable
segments will be kept from contacting the heat source, sharp points or edges.
Use high temperature cables near the heat sources;
■
For the cable terminals fixed using screw threads, the screws or nuts should be
securely fastened and prevented from loosing. See the following figure;

Verifying the Installation
71
■
When using a hard power cord, fix it near its terminal so as to free the terminal
and the cable from stress;
■
Do not use tapping screws to fasten the connecting terminals;
■
The power cords of the same type and in the same direction should be bundled
together and kept neatly and straight;
The following table lists the requirements in the bundling with cable ties.

■
No cable or bundle can tie a knot;
■
The metal parts of the crimped cold-pressed terminal blocks (such as air switch)
cannot stretch beyond the blocks.
Verifying the
Installation
c
CAUTION: Confirm that you have turned off the power before checking,
otherwise, improper connection will hurt people or impair the components of the
switch.
After installing the switch, verify the installation by the following list, ensuring all
the checking results are normal.

SWITCH MONITORING AND
MAINTENANCE
Monitoring the Switch
Although the Switch 8800 Family has undergone a comprehensive and strict
factory test before delivery, there might be some fault occurring due to improper
installation. This chapter describes how to troubleshoot the Switch 8800 Family.
Troubleshooting Console
Terminal
If the system is normal after the Switch is powered on, the booting information
will be displayed on the Console terminal. If the configuration system has failed,
the Console terminal may give illegible output or nothing at all.
1 The terminal gives no displays after the Switch is powered on.
In this case, you should check if:
■
The power system is working normally.
■
The fabric is working normally.
■
The Console cable has been connected to the Console port on the fabric.
If no problem has been found in the above checking, the symptom is very likely
caused by the errors listed below.
■
The Console cable is not connected to the right serial port, that is, the port in
use is not the one configured on the terminal.
■
There are Console terminal parameter errors. (According to the parameter
setting requirements, you should set the baud rate to 9600, data bits to 8,
parity to None, stop bits to 1, flow control to None, and select VT100 as
terminal emulation.)
■
The Console cable is not in good condition.
2 The terminal gives illegible characters.
This symptom is very likely caused by a Console terminal setting error. In this case,
check that you have set the baud rate to 9600, data bits to 8, parity to None, stop
bits to 1, flow control to None, and select VT100 as terminal emulation.
Troubleshooting PSU
Table 73 Description of the LEDs on PSU

Description
INPUT
It keeps ON if the power input is normal and the PSU switch is at ON position. It
keeps OFF if the power input has failed or if there is no power input at all.
OUTPUT
It keeps ON if the power output is normal and OFF in any other cases.
FAIL
It keeps ON if the PSU has failed and OFF in any other cases.
Following are the PSU faults that likely appear and the methods used for problem
isolation.
78
CHAPTER 6: SWITCH MONITORING AND MAINTENANCE
Troubleshooting Fan
Tray
■
The Input LED (green) and Output LED (green) stay ON, but the display power
command shows that the PSU is not in position (but the other PSU operates
normally). Such a problem is likely caused because of the poor contact
between the PSU and the backplane due to a badly seated PSU. In this case,
switch off the power supply, loosen the captive screws on the PSU, push the
PSU into the chassis a little bit, tighten the captive screws, and switch on the
power supply to check that the normal state is resumed.
■
The Input LED (green) and Output LED (green) are OFF. In this case, check that
the power cords are connected correctly, the power cords are in good
condition, and the power switch has been put in the ON position.
■
The Fail LED (red) is ON. In this case, check that the correct power voltage is in
use (i.e., 90 to 264VAC, 50-60 Hz for AC PSU).
■
The Fail LED (red) is ON. In this case, check that the air filter protecting the fan
tray is clean. Excessive dust accumulated on the air filter will block the fan tray
from free ventilation and even lead to power supply failure.
■
If you cannot solve the problem yet after going through the above checking
steps, contact 3Com technical support engineers rather than disassembling the
PSU yourself.
The Switch 8800 Family provides two LEDs on the fan tray. You can read them and
know if the fan tray is OK.

power cord.
Step 3: Unscrew the captive screws on the both sides of the PSU panel with a
flathead screwdriver.
Step 4: Hold the handle of the PSU and pull the PSU gently out of the chassis
along the guides.
80
CHAPTER 6: SWITCH MONITORING AND MAINTENANCE
Figure 56 Remove and install the AC PSU
You can remove AC PSU from the 8810/Switch 8814 in similar way.
c
CAUTION:
■
The Switch 8800 Family uses multiple power systems, and you must turn off all
of them when removing the AC PSU.
■
As the PSU of the Switch 8800 Family is heavy, use both hands to pull it out
slowly and gently, with one holding its handle and the other holding its
bottom.
■
If you do not want to install a PSU, insert a blank filler panel into the PSU slot
for dust-proofing and guaranteeing ventilation.
Installing AC PSU (Switch 8807 as example)
Step 1: Hold the handle of the PSU with one hand and the bottom of the PSU with
another hand, and gently slide the PSU into the chassis along the guides until it
mates the backplane well.
Step 2: Fasten the captive screws at both sides of the PSU panel with a flathead
screwdriver.
Step3: Check that the power switch on the panel is in the “OFF” position and the
clamp holding the power cord connector has been pulled up.
Step 4: Insert the AC power cord accompanied the Switch into the socket on the
PSU.
Step 5: Pull the clamp down to hold the power cord.
You can install AC PSU to the 8810/Switch 8814 in same way.

CHAPTER 6: SWITCH MONITORING AND MAINTENANCE
Replacing and Cleaning
the Air Filter of Chassis
c
CAUTION: You are strongly recommended to clean the air filter semimonthly to
guarantee adequate ventilation.
The air filter of the Switch 8800 Family is installed at the air intake vents of the
chassis. If you do not clean the air filter often, the dust accumulated on it will
block the holes of the filter, hence affecting the ventilation of the chassis. For this
reason, you are recommended to clean the air filter at a proper interval.
Both methods of dry-clean and rinsing are allowed. However, take care not to rub
the air filter when you wash it, and simply air it after that.
Removing and cleaning the air filter of chassis
Step 1: Unscrew the captive screws at the top and bottom of the air filter with a
flathead screwdriver.
Step 2: Hold the air filter at the left-rear by its upper and lower edges, pull part of
it out of the chassis, put one hand underneath the air filter to hold it, and pull it
out slowly along the guides.
c
CAUTION: As the air filter is rather long, you should hold its front end with one
hand, and bear its weight by putting another hand underneath it when sliding the
air filter out of the chassis.
Step 3: Rather than taking the air filter mesh out, directly wash the air filter after
removing it from the chassis, air it, and insert it into the chassis again.
Installing the air filter of the chassis
Step 1: Hold the front end of the air filter with one hand and put another hand
underneath it, align it with the guides, and slide it into the chassis along the
guides.
Step 2: Fix the air filter by fastening the captive screws at the top and bottom of
the air filter with a flathead screwdriver.

Upgrading software through console port (XModem)
1 Brief introduction to XModem
XModem, a type of file transfer protocol, is broadly applied for its simplicity and
good performance. It transmits files through serial interfaces, supporting 128
bytes and 1Kbytes in terms of data unit, checksum and CRC in terms of checking
mode, and multiple retransmissions (usually ten attempts) in the event that packet
errors are found.
Software Upgrade
87
XModem completes transmission by the receiving program (receiver) and the
sending program (sender). In XModem, the transmission begins with the sending
of negotiation characters from the receiver for the purpose of check mode
negotiation. After passing the negotiation, the sender is allowed to send the first
data packet. Upon the receipt of the complete packet, the receiver checks the
packet using the agreed checking mode and will send an ACK if the packet has
passed the check and a NAK if not. Receiving the ACK, the sender will send the
next packet; receiving the NAK instead, the sender will retransmit the previously
sent packet.

Upgrading software through management Ethernet port (TFTP)
1 Introduction to TFTP
Trivial file transfer protocol (TFTP) is well suited to the file transfer between a server
and a client that do not need complex interaction.
In TFTP, the transmission is initiated by the client. When downloading a file, the
client sends a read request packet to the TFTP server, receives the data packets
from the server, and sends the ACK to the server. When uploading a file, the client

89
sends a write request packet to the TFTP server, then sends the data packets to the
server, and receives the ACK from the server. The TFTP transmission files have two
forms, i.e., binary for program transmission and ASCII for text transmission.
Following is the upgrading procedure described taking the Switch 8814 working
as a TFTP Client as an example.
2 TFTP upgrade procedure
Step 1: Connect the Switch to a PC where the desired file is located via the
management/upgrade Ethernet port. (In this case, you should know the IP address
of the PC. At the same time, connect the Switch to an external PC (that can be the
same one that contains the desired file) via the Console port.
Step 2: Run the TFTP Server program on the PC connected to the
management/upgrade Ethernet port, and specify the path for upgrading the
application files.
Step 3: Run the terminal emulation program on the PC connected to the Console
port, and boot the switch to access the Boot menu.
Step 4: Enter 5 in the Boot menu. Press Enter and the system will access the
download application program menu.

Local or Remote Loading
through CLI
If your terminal is connected to the switch over a network, you can load Boot
ROM and host program at the remote through CLI.
Loading using FTP
Run FTP server on a local PC, provided you have configured username and
password and have set the correct file directory. Suppose IP address of the PC is
10.10.110.1. Log on to the switch using Telnet or through the Console port to
send host program to the switch using FTP.
Suppose that the main boot file is SWITCH002.app; the active host program is
SWITCH001.app; the Boot ROM program is SWITCHbtm.btm. You can follow
these steps after logging on to the switch.
Step 1: Download the software to the switch using FTP.

If the switch has two fabrics, you also can copy the host and Boot ROM program
files to the standby Fabric.
Step 2: Specify the next boot program. If the switch has two fabrics, specify the
load programs respectively for the active and standby fabrics. Suppose the current
standby fabric is at slot 7.

CAUTION:
■
You must reboot the switch using the reboot command to validate the host
program. If Flash memory space is not enough, you can delete some of the
program files in Flash after completing the Boot ROM loading. (You are
recommended to delete the host program that is no longer in use.) Then
upload the host program to the switch using FTP.
■
Make sure that you have saved other configurations before rebooting;
otherwise, they might not survive a reboot.
■
Power-off is forbidden during loading process.
Boot ROM and host program loading is completed now.
Remote and local loading using TFTP
Using TFTP is similar to using FTP in remote and local loading via commands. The
only difference is that you use the tftp get command to download software to
the switch. In this case, the switch can only be used as a TFTP client to download
the software to its Flash memory from the TFTP server. The remaining steps after
downloading are the same as those of remote loading using FTP.
Application Module
Program Upgrade
If you have the 360G Fabric (3C17508), download the application software image
files to the compact flash (CF) and then boot from the CF.
Password Loss
93
If you have the 720G Fabric (3C17539), download the application software image
files directly to the Fabric’s onboard flash.
Troubleshooting
Software Upgrade
These types of problems may occur during software upgrade:
No response from fabric serial interface
Check if the serial interface cable is in good condition and if its attributes are set
correctly.
Uploading configuration file or host program using FTP fails
Please check
■
If the configuration is correct and if the FTP server is started.
■
If the Flash has enough space for the target files.
■
If the TFTP flag is selected (TFTP is not supported).
No configuration saving during I/O module reboot
Before saving the configuration, you must check the operating status of the I/O
module. Do not save the configuration during the I/O module reboot. Otherwise,
the configuration you want to save may be lost.
I/O module program loading fails or you cannot register for a long period
■
Check I/O module type to see if this type is supported on the current host
program.
■
Check if the I/O module Boot ROM program matches the host program before
upgrade.
■
Check if I/O modules are well seated.
■
Insert an I/O module to different slots to check if it is OK.
■
Check if the host program exists and if the current host program is the running
one.
Insufficient Flash memory
Password Loss
■
Empty the recycle bin when the I/O module starts.
■
Delete the unused files in the Flash.
If the Super password or Boot ROM password of the Switch is lost, please contact
your local support representative.

Protection)
c
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.

CHAPTER A: LIGHTNING PROTECTION OF THE SWITCH
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 to that 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.
Installation of
Lightning Arrester for
Network Port
n
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).
c
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.
Required tools
■
Phillips screwdriver or Flat-module screwdriver
■
Multimeter
■
Tilted wire cutter
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
contacts well 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
Installation of Lightning Arrester for Network Port

connected to the switch should be inserted into the arrester’s OUT end). When
you do that, observe whether the arrester indicators normally display.
n
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.

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
for protection.
