MBUS 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.

C

HAPTER

1: P

RODUCT

O

VERVIEW

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.

Safety

Recommendations

To avoid possible bodily injury and device impairment, please read the following safety recommendations carefully before installing the Switch 8800 Family. The recommendations do not cover every possible hazardous condition.

General Safety

Recommendations

■

■

■

The Switch 8800 Family use redundant PSUs. Turn off all PSUs and remove all the power cords before opening the chassis.

Keep the chassis clean and dust-free.

Keep the chassis and installation tools away from walk areas.

Safety

Recommendations against Electricity

■

■

■

■

■

■

Look carefully for possible hazards in your work area, such as ungrounded power extension cables, missing safety grounds, and moist floors.

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.

Safety

Recommendations in

Moving the Switch 8800

Family

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.

c

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.

REPARATION

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

49

Cleanness Requirements

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

Dust particle particles/m 3

Content

‚

≤

3 x 10 4

(No visible dust on desk in three days)

Note: Dust particle diameter ‚

≥

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 SO

Anti-Static

Requirements

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.

Grounding

Requirements

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.

Space Requirements

For the sake of adequate ventilation and easy equipment maintenance, you are recommended to keep one meter of clearance between the rear/front of the switch cabinet and the wall surface or other devices. If the optional cabinet is desired, the clear height of the equipment room must be more than 3 meters inclusive.

Cabinet-Mounting

Requirements

Before cabinet-mounting the switch, make sure that the cabinet meets the following requirements:

■

Better mount the switch in an open cabinet. However, if you want to mount it in a closed cabinet, make sure of the availability of a good ventilation system.

■

■

Make sure that the cabinet stands steadily enough to support the weight of the switch and the accessories.

Make sure that the switch fits the cabinet size. Leave some clearance beside the left and right panels of the switch for chassis ventilation.

Mounting the Switch in the Cabinet

Take the following steps to install the Switch 8800 Family in a 19-inch cabinet.

Step 1: Confirm before installation

■

■

Make sure that the cabinet has been well fixed. The layout inside the cabinet for switch installation has been well done and there is no obstruction inside or around the cabinet.

Make sure that the switch is ready for installation and has been carried to a place convenient for further moving near the cabinet.

Step 2: Mount a shelf inside the cabinet depending on the position where you want to put the switch.

Step 3: Install the cabling rack and attach the mounting ears shipped with the switch onto the switch.

Step 4: Carry the switch at both sides with another person to the place in front of the cabinet slowly.

Step 5: Lift the switch a little higher than the cabinet shelf, put it on the shelf, and push it into the cabinet.

c

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).

n

All the megabit and gigabit optical modules available for the Switch 8800 Family are SFP modules that provide LC user ports.

Introduction to fiber connector

n

■

■

When selecting a fiber network facility, make sure that the type of the connector and the fiber match the adopted optical port.

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.

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

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.

Cabinet-Mounting

Switch

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.

Figure 51 Cable bundling example I

Cable Management

69

■

■

■

■

■

■

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

WITCH

I

NSTALLATION

■

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;

Figure 54 Cable fixing example

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.

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.

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.

Troubleshooting Fan

Tray

The Switch 8800 Family provides two LEDs on the fan tray. You can read them and know if the fan tray is OK.

Table 74 Description of fan tray LEDs

Indicator State description

RUN Green indicates that the fan tray is normally operating.

OFF indicates that the fan tray has failed.

ALM Red indicates that the fan tray has failed.

OFF indicates that the fan tray is in normal state.

n

The ALM LED on the fan tray keeps ON for 2 to 3 seconds when the switch is powered on.

If the RUN LED is OFF, check if:

■

■

■

■

■

The fan tray has been well seated.

All the cables connecting the fan tray and the backplane have been correctly connected and are in good condition.

The fans are working normally.

The rotation of the fans has not been blocked.

The blank filler panels have been inserted into those I/O module slots.

Troubleshooting I/O

Module

The Switch 8800 Family provides I/O moduleX LEDs on the fabric for the user to observe the state of these I/O modules.

■

■

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.

Replacing and Cleaning the Air Filter of PSU

The AC PSU air filter can be replaced.

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

Software Upgrade

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.

Step 1: Connect the Switch to the PC containing the desired file 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 FTP Server on the PC connected to the management/upgrade Ethernet port, specify the path of the upgrading file, and set the login username and password.

Step 3: Run the terminal emulation program on the PC connected to the Console port, and boot the Switch to access the Boot menu.

Steps 4 ~ 8: See the corresponding steps in the upgrading procedure via TFTP for reference.

n

If you want to download files using FTP, please set the flags to 0x0 when setting the Ethernet interface parameters.

After downloading the host program through the Boot menu, you must specify it as the next boot program. In the following example, the host program is Switch

8800 Family-Comware 310-R1212.app.

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.

The app to boot of board 7 at this time is: flash:/SWITCH002.app

<3Com> reboot c

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.

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.

■ 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 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 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.
