Power Supply The Switch 8800 power supplies are installed at the bottom of the chassis, in the

front. Only one AC power supply is required for each Switch 8800 chassis, although 2 power supply slots are provided to implement 1+1 redundancy.

The 7-slot chassis uses a 1200 W auto-ranging power supply (3C17506).

The 10- and 14-slot chassis use a 2000 W auto-ranging power supply (3C17507). When this power supply is used at 110 V, it delivers 1200 W of power, when used at 220 V, it delivers 2000 W of power.

Do not combine 1200 W and 2000 W power supplies in the same chassis. If you have two power supplies in your Switch 8800 chassis, they must be of the same type.

Installing Cabling This section describes how to install and bind cables for your Switch 8800.

Bench-Mounted Switch If you have installed your chassis on a bench, all interface cables run on the left

side of the chassis in the cabling channel, and the chassis power cords run by the rear chassis panel.

Rack-Mounted Switch If you have installed your switch in a 19-inch standard rack, the cables are bound

on the cable binding rack at the left side of the chassis and arranged to run on the cable rack or under a raised floor. Collect all the transit data signal cable connectors and locate them on the floor of the chassis. Power cords run out of the rear left of the chassis and on a cable rack or under a raised floor.

Cable Binding Keep the following precautions in mind as you bind cables:

■ Do not allow cables to twist or bend as you bind them.

■ The cable body cannot be bent at an angle that is more than twice its diameter.

The cable running out of a connector cannot be bent more than five times its diameter.

■ Different types of cables (power cord, signal cable, and ground wire) should

not be bound together in a rack. Although different types of cable may cross over each other, they must not be bound together where they cross. For parallel cabling, the space between a power cord and a signal cable should be no less than 30 mm (1.25 in).

■ The cable binding rack and cable channel inside and outside a rack should be

smooth.

■ The hole through which a cable runs through should be smooth or have a

rubber grommet.

■ Use plastic cabling ties to bind the cables.

■ Bind cables before bending them. Ensure that no tie binds the bent part of any

cables to prevent the core of the cable from breaking.

■ Do not tie power cables to the guides of any mobile components.

■ For the cable terminals fixed with screws, the screws or nuts should be

fastened securely.

■ Do not use tapping screws to fasten the cabling terminals.

Using Xmodem

The Xmodem protocol transmits files through serial ports and supports both 128-byte and 1K-byte packets. Xmodem also supports two types of check; normal checksum and CRC. When there is a packet error, retransmission is supported, normally 10 times.

The Xmodem protocol completes transmission by receiving and sending programs. The receiving program first sends the negotiating characters to negotiate the check means. After passing the negotiation, the sending program begins to send the packet.

The receiving program checks the packet according to the negotiated means after receiving a complete packet. The acknowledgement characters are sent after passing the check and then the sending program continues to send the next packet. If the check fails, negative characters are sent and the sending program sends the packet again.

Using TFTP

TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is used without complex interaction between clients and servers.

The client initiates a TFTP transmission. To download files, the client sends a read request packet to the TFTP server, receives the packet from the server, and sends the acknowledgement to the server. To upload files, the client sends a write request packet to the TFTP server, sends the data packet to the server, and receives the acknowledgement from the server.

The Switch 8800 provides the functions of the TFTP client.

A TFTP Server program is shipped on the CDROM with the Switch 8800.

Before you upgrade:

■ Verify that there is a connection between the TFTP server and the Switch 8800

(use the

■ Verify that the TFTP server is set up according to the manufacturer's instructions

ping command.)

and that it is enabled and pointing to the correct directory.

To upgrade using TFTP:

1 Verify that you are logged in with super-user privileges.

2 From the Switch 8800 command line (in user view), TFTP the image file from the

TFTP server to the Switch 8800 using the following command:

tftp <TFTP Server IP Address> get <Source File/image>< Dest File-Optional>

3 Set the boot parameters to specify the file to boot the system from, using the

following command:

boot boot-loader filename

4 Reboot the system.

The following example illustrates this procedure:

<SW8800>tftp 192.168.25.210 get 88003.app Transfer file in binary mode. Now begin to download file from remote tftp server, please wait... / TFTP: 5690749 bytes received in 376 second(s). File downloaded successfully.

Managing Software Backup

The Switch 8800 uses the application and configuration files it finds on the Flash of the Fabric from which it booted the previous time. To back up these files, you can copy them from Flash to compact Flash. However, there are some important things to know before you copy files to compact Flash:

■ If the Switch 8800 has two Fabrics installed, and you execute a save

command, it synchronizes the configuration file on the Flash on both Fabrics so that both Fabrics can use the same configuration information.

■ The Switch 8800 does not synchronize versions of the application file between

Fabrics. Therefore, you must manually download the application file to one Fabric, then copy the application file between Flashes to insure that both Fabrics can boot from the same file.

■ To insure that both Fabrics boot the same way, you must configure boot

parameters with the same values on each Fabric.

■ The system does not synchronize files between compact Flash cards or

between compact Flash and Flash.

■ For compact Flash to serve as a reliable file backup, you must take care that

files are copied to compact Flash after every modification or download. Otherwise, you could have multiple versions of a file on your system.

To verify the names and contents of the Flash and compact Flash on your system, you can use the

<SW8800>dir ? /all List all files STRING<1-136> [drive][path][file name] cf: Device name flash: Device name slot5#cf: Device name slot5#flash: Device name <cr>

dir commands, as shown in the following examples:

The entries cf and flash refer to the compact Flash and Flash on the Fabric from which the system last booted. If more than one Fabric is intalled on the Switch

MAINTAINING HARDWARE

This chapter covers the following topics:

■ Replacing a Power Supply

■ Replacing I/O Modules

■ Replacing the Fan Assembly

The procedures in this chapter should be performed by trained service personnel only.

Replacing a Power Supply

To replace a power supply, you need:

■ An antistatic wrist strap

■ A screwdriver

WARNING: When installing or replacing the power supply when the power is on, do not touch any naked wire, terminal, or any other part of the product labeled Dangerous Voltage. Always wear the antistatic wrist strap when replacing the supply.

Use the following steps to replace a power supply:

1 Turn off power to the power supply you are replacing.

2 Pull up on the retention clip that holds the power cord connector and unplug the

power cord.

3 Loosen the captive screws on both sides of the power supply.

4 Support the power supply with one hand and gently pull the handle with the

other hand until it slides out of the slot.

5 If you are not going to install another power supply in this slot, install a blanking

plate on the chassis for dust-proofing and heat dissipation.

6 Remove the new power supply from the package and verify that the correct input

mode is selected.

7 Support the power supply, right side up, in one hand and hold the handle with

another hand. Align the supply with the guides in the chassis and slide the power supply into the slot.

CAUTION: As you are inserting the power supply, if the pin terminal springs up, the pin cannot be seated into the hole and the system will sound an alarm. If the power supply has not been inserted properly, you should slide it out and insert it again to avoid breaking or cracking the power terminals.

8 Fasten the captive screws.

48 CHAPTER 5: MAINTAINING HARDWARE

CAUTION: If the captive screws cannot be fastened, the power supply may not have been properly seated. Remove and replace the supply.

9 Insert the power cord connector into the power socket on the power supply and

lower the retention clip.

Cleaning the Power

Supply Filter

Over time, the filter on the power supply accumulates dust, which interferes with the heat dissipation of the chassis. It is important to periodically clean the filter as described below:

1 Remove the gauze filter by gently pulling it from the front of the power supply.

2 Take the filter to a fresh water supply and clean it.

3 Leave the filter to dry. Do not use heat to dry the filter as this may cause it to

distort.

4 When the filter is completely dry, gently push it back into the front of the power

supply.

CAUTION: Do not clean the filter while it is in position at the front of the power supply. Attempts to do so could result in damage to the equipment or severe electrical shock.

Replacing I/O Modules To replace an I/O module, you need:

■ An antistatic wrist strap

■ A screwdriver

To remove a module:

1 Remove all the cables from the module to be removed.

Replacing the Fan Assembly

2 Loosen the captive screws.

3 Hold the ejector levers on the module with both hands, and press them toward

both sides to separate the connectors of the module from the motherboard.

4 Gently slide the module along the guides and out of the slot.

5 Put the removed module into the package that contained the replacement

module.

Replace the blank plate on the chassis if you do not install a new module in the place where the old one was removed.

To install a replacement module:

1 With both hands, hold the ejector levers on the module that will be installed.

2 Align the module with the guides in the chassis and slide it into the slot gently

until you feel the positioning pin on the handle bar touch the hole in the chassis.

3 Press the ejector levers inward and seat the pin on the handle bar into the

positioning hole in the chassis.

4 Fasten the captive screws to fix the module.

You can hot-swap fan assemblies in the Switch 8800.

Replacing the Fan Assembly 49

To replace a fan assembly, you need:

■ An antistatic wrist strap

■ A screwdriver

WARNING: To avoid injury:

■ Do not touch any naked wire, terminal, or any part of the product labeled

Dangerous Voltage. Always wear the antistatic wrist strap when replacing the fan module.

■ Keep hands away from fan blades when removing the fan assembly because

fans continue to turn after the assembly is removed.

To replace a fan assembly:

1 Put on the antistatic wrist strap.

2 With both hands, pull out the ejector levers on the fan assembly to separate the

fan assembly connector from the backplane.

3 Pull the fan gently along the guides of the slot to remove it.

4 With both hands, pull out the ejector levers of the fan that will be installed. Align

it with the guides in the chassis and slide it gently into the slot until you feel the positioning pin on the handle bar touch the hole in the chassis.

5 Press the ejector levers inward and seat the pin on the handle bar into the

positioning hole in the chassis.

WARNING: If the fan fails, replace it with a new one without delay before operating the Switch 8800. Failure to do so will cause the switch to overheat.

50 CHAPTER 5: MAINTAINING HARDWARE

TROUBLESHOOTING

This chapter covers the following topics:

■ Troubleshooting the Configuration

■ Troubleshooting Power

■ Troubleshooting the Fans

■ Troubleshooting I/O Modules

The simplest way to diagnose a fault is to check the system status LEDs on the Fabric modules. In addition, with the DeviceMgr network management system, you can also locate the fault through management software.

Troubleshooting the Configuration

No information is

displayed on the

terminal

The displayed characters

are illegible

After the switch is powered on, booting information is displayed on the configuration terminal. If the configuration system has failed, there is no screen display at the configuration terminal or the displayed characters are illegible.

If there is no information displayed on the terminal after the Switch 8800 is powered on, check that:

■ 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 this procedure does not reveal the problem, verify the following:

■ The console cable is connected to the serial port that is configured on the

terminal.

■ Console terminal parameters are set properly. See “Setting Terminal

Parameters” on page 29.

■ The console cable is not damaged.

If the displayed characters are illegible, the console terminal parameters may not have been set correctly. See

“Setting Terminal Parameters” on page 29.

Troubleshooting Power

Ta bl e 32 describes power LEDs on the power supply.

Ta bl e 32 Power LEDs on the Power Supply

LED Status Description

INPUT On — The power input is normal and the power supply switch is in

the ON position. Off — The power input has failed or has not been turned on.

52 CHAPTER 6: TROUBLESHOOTING

Table 32 Power LEDs on the Power Supply (continued)

LED Status Description

OUTPUT On — The power output is normal.

Off — The power output has failed.

FAIL On — The power supply has failed.

Off — The power supply is operating.

The following list describes potential problems with the power supply and their solutions.

■ The INPUT LED and OUTPUT LED are on, but the display power command

shows that the power supply is not in position. The other power supply is operating normally.

This problem may be caused by poor contact between the power supply and the backplane if the power supply is badly seated. To resolve this, do the following:

■ Switch off the power supply.

■ Loosen the captive screws on the power supply.

■ Push the power supply into the chassis.

■ Tighten the captive screws.

■ Switch on the power supply and verify that it is operating normally.

■ The INPUT LED and OUTPUT LED are off.

Verify the following:

■ Power cords are connected correctly

■ Power cords are in good condition

■ The power switch is in the ON position.

■ The power supply is installed right side up.

■ The FAIL LED is on.

Verify the following:

■ The correct power voltage is in use: 90 to 264 V AC, 50 to 60 Hz.

■ The air filter protecting the fan frame is clean. If dust has accumulated on

the air filter will block the fan frame from free ventilation and even lead to power supply failure.

If you cannot resolve an issue with the power supply after using these procedures, contact your 3Com Service Representative. Do not attempt to repair the power supply yourself.

Troubleshooting the Fans

If the fan OK LED is off, check that:

■ The fan assembly has been installed in the correct position for normal

communication with the backplane and the cables are in good condition.

■ Every fan is working normally.

Troubleshooting I/O Modules 53

■ There is nothing blocking the vent of the chassis.

■ The blanking plates are installed on the chassis where no module is inserted.

Ta bl e 33 describes fan assembly LEDs on the faceplate of the fan assembly.

Ta bl e 33 Fan LEDs on the Fabric

LED Status Description

RUN On — The fan is working normally.

Off — The fan has failed or has not been installed.

ALM On — The fan has failed.

Off — The fan is operating normally.

Troubleshooting I/O Modules

The Fabric has LEDs that indicate the status of the I/O modules , as described in Ta bl e 34.

Ta bl e 34 I/O Module LEDs

LED Status description

RUN Green or off — The module failed or has not been inserted.

ALM Off — The module is working normally or has not been

Green flashing, slow — The module is working normally. Green flashing, fast — The module is booting or is not registered successfully.

inserted. Green or green flashing — The module failed or is not working normally.

Ta bl e 35 shows the correspondence between the I/O module LEDs on the Fabric and the slots in which these I/O modules are installed.

Ta bl e 35 I/O Module LEDs and Corresponding Slots

Chassis LEDs Slots

7-slot 0 to 4 2 to 6

10-slot 0 to 7 0 to 3 and 6 to 9

14-slot 0 to 11 0 to 5 and 8 to 13

■ If the ALM LED of the module remains green or green flashing, it indicates

there is something wrong with the module.

■ During the process of resetting the module, the ALM LED remains on. After

normal booting, it is off.

■ When resetting the module, if the ALM LED remains off, the module may not

be connected to the power source.

Check that the module has been properly installed in the correct position.
