Pre-installation Guidelines

Before mounting the 8265 in a rack:

1. First make sure the selected rack can support at least three times the weight of a fully- loaded switch.

2. Bolt the rack to the floor.

3. Brace the top of the rack to the wall.

4. Ensure that there is sufficient vertical space in your rack for each 8265 you wish to install.

5. Install patch panels in the rack for easier cable management.

6. Rack mount flanges are set to flush mount at the factory. If desired, change the rack mount flange

position by removing the screws that attach each flange to the switch. When re-installing the rack

8. Install the Cable Management Tray beneath the switch. The tray is designed to manage the cables

attached to the front of the switch by feeding them under and through the back of the unit. Use of the
cable tray is optional. You can mount the cable tray onto the rack in one of four positions. Mount the
switch using the same rack mount position settings as those used to mount the cable tray.

Chapter 3. Installing the Chassis 13

CAUTION:
You can install the switch in the rack either before or after you install the Cable Management
Tray, but the tray must be installed below the switch. Never allow an installed cable tray to
support the weight of the switch. The weight of a switch resting on a rack mounted cable tray
may cause the tray to buckle or separate from the rack. Personal injury may result.

Installing the Switch on a Table or Shelf

Though it is recommended that you install the 8265 switch in a rack, you can also install the switch on a
table or shelf.

CAUTION:
Do not use the Cable Management Tray when installing the switch on a table top or shelf.

If you choose to install the rubber feet, be advised that the switch could tip over under certain
conditions. Hardware damage or personal injury may result.

Safety regulations state that the selected table or shelf must be able to support at least three times
the weight of a fully loaded switch.

To install the 8265 switch on a table or shelf:

1. If you wish to install the rubber feet to the switch, lay the switch on its side on the table or shelf so the

bottom of the switch is accessible.

2. Optionally, remove the rubber feet (4) and the screws supplied (4) from the plastic bag in which they

were shipped and fasten the rubber feet to the bottom of the switch with the screws.
Figure 6 shows how to attach the rubber feet to the bottom of the switch.

Installing a DC Power Supply

This section describes how to prepare and install the -48 Volt DC power supply and power cord in your

8265.

CAUTION:
Only trained electrical service personnel must make connections and disconnections to the -48
Volt DC power source.

A circuit breaker (short-circuit protection) must be set up in the main power source. This circuit
must be grounded to a safety ground. For each power supply use one 20-A protection device to
protect the cabling of the -48 Volt DC power supply against short-circuits.

To comply with UL requirements, the -48 Volt DC Power Supply must only be installed in a
rack-mounted 8265 installed in an enclosed cabinet.

The -48 Volt Power Supply switch only shuts off the output side of the power supply.

Before You Begin

This section describes what you should know before you begin installing the -48 Volt DC Power Supply in
your 8265:

1. Verify that the power source is compatible with the voltage and tolerances specified on the input rating

plate located on the power supply unit. The nominal value is -48 Volt DC, 11 Amps.

2. Remove the following items from the shipping box:

 Power supply unit
 Power input cable
 Bags containing the terminal rings.

The -48 Volt DC power supply ships with 3 bags of terminal rings:

– Part Number AMP 320563, contains 1 terminal ring for only the green/yellow ground wire.
– Part Number AMP 31890, contains 4 terminal rings for the red and black wires.
– Part Number AMP 31880, contains 4 terminal rings for the red and black wires.

The -48 Volt DC power supply ships with different size terminal rings. One terminal ring is for only the
green/yellow ground wire. The remaining terminal rings are used with the red and black wires. Choose
the correct the terminal rings to support your installation.

The AMP part number for the terminal crimping tool is AMP # 58433-2 (this includes the correct
crimping die set). The AMP Die Set part number is 58423-1 (for people that already have the crimping
tool with other dies).

Preparing and Installing the DC Input Power Cords

Note: The following terminal ring installation shows how you install terminal rings to the power cord. The

installer should adapt the building DC input and make the power cord connection using the
terminal rings shipped with the power supply or whatever method is necessary to meet system
installation requirements. For compatibility with the building power source, the installer chooses
which size terminals rings are to be crimped on the power cord wires.

To prepare and install the -48 Volt DC input power cords:

1. Obtain the power supply cables that you removed from the shipping boxes. The input power cables

have 3 groups of wires. Each wire is labeled with the corresponding voltage. The 2 red wires are
labeled 48VDC and the 2 black wires are labeled 0VDC.

 How to install the 8265 Controller module(s)
 Guidelines for installing 8265 media modules
 Guidelines for installing 8260 media modules.

Before You Start

Take the following precautions before unpacking any modules:

 Do not remove components from their anti-static bags until you are ready to install the modules in the

8265. This avoids the possibility of having electrostatic discharge damage static-sensitive devices on
the components.

 Always use a floor strap and grounded mat, or wear a grounded static discharge wrist strap whenever

you inspect or install a module. Alternatively, touch a grounded rack or another source of ground
before handling the module.

 Verify that the module (and daughter cards if required) are correct by matching the part number listed

on the side of the shipping carton to the part number you ordered.

 Copyright IBM Corp. 1994, 1998 27

Unpacking Modules

When unpacking modules, follow these steps:

1. Remove the anti-static bag containing the module from the shipping carton.

2. Remove the module from the anti-static bag and inspect it for damage. Always handle modules by
their faceplates, being careful not to touch the internal components.

If the module appears damaged, put it back in the anti-static bag, and put the bag back into the
shipping carton. Then contact your local IBM dealer or IBM representative.

It is recommended that you retain the shipping carton and anti-static bag in case you later want to
repackage the module for storage or shipment.

28 IBM 8265: Installation Guide

Installing the Control Point and Switch Module
Before You Begin

Before installing a Control Point and Switch module:

 Make sure that you also have the PCMCIA card containing the Control Point and Switch microcode.

There are two versions, a basic version containing IISP and UNI protocols, and an enhanced version
with additional PNNI protocol. One of these MUST be installed on the module before the module is
installed in the 8265.

 If you are installing the memory upgrade for the standard Control Point and Switch module, make sure

that it is to hand.
The memory module must be installed on the Control Point and Switch module before its insertion in

the 8265.

 (CPSW2 module only) — Check that the Power Control jumper setting is in the correct position. To

use the integrated power control functions, the FORCE RCTL jumper must be in the OFF (down)
position. If you are using Controller modules for power management, the jumper must be in the ON
(up) position.

Important!: If you are installing two CPSW2 modules, the jumper setting must be the same on both

modules.
Attention: You must not install an 8260 CPSW module into the 8265.
Figure 15 illustrates the PCMCIA card slot, memory bank location, and the location of the Power Control

(FORCE RCTL) jumper (CPSW2 modules only).

1. Remove the card from its packaging.

2. Position the card so that it is just above the slot on the CPSW module, making sure that the edge with
the connectors is inserted first.

3. Slide the card into the slot.

4. Push gently downward until the card clicks into place. If the card does not seat properly, turn the card
over and try again. The card will not click into place when inserted back-to-front.

To remove a PCMCIA card, simply press down on the small lever on the left of the slot.

30 IBM 8265: Installation Guide

Installing the Memory Upgrade

To install the memory upgrade:

1. Remove the memory module from its packaging.

2. Locate the end of the module that has a small notch.

3. Position the module above the vacant socket on the CPSW module, making sure that the end with the

notch is facing to the rear of the module.

4. Gently insert the module into the socket at 45 degrees.

5. Push gently downwards on the module until it clips into place.

To remove a memory module, release the clips at either end of the module, then slide the module
upwards gently and lift out.

Chapter 5. Installing Modules 31

Installing the Module

To install a CPSW module:

1. Insert the CPSW module into slots 9 and 10, or 11 and 12 of the switch by matching the top and
bottom board guides as you slide the module cleanly into place (by pressing evenly on the top and
bottom of the faceplate).

2. Check that the module is plugged into the connectors on the ATM backplane.

3. Fasten the spring-loaded screws on the top and bottom of the front panel of the module to the chassis
using your finger. Do not over-tighten.

4. If the switch is already powered on, press the LED Test button to ensure that all LEDs are functional
(optional).

5. Repeat the above steps for the second module if you are installing two.

32 IBM 8265: Installation Guide

Installing the Controller Module

Controller modules are only required when the standard CPSW module is to be used (Controller module
functionality is in-built in the enhanced CPSW2 module). Controller modules may be installed in
conjunction with a CPSW2 module if you prefer power management to be handled by the Controller
module instead of the CPSW2 module. When using Controller modules with CPSW2 module(s), the
FORCE RCTL jumper on the CPSW2 module(s) must be set to the ON position (see ,Figure 15 on
page 29 for the jumper location).

The 8265 Controller modules must be installed in the Controller module slots. These slots are located at
the lower right front corner of the switch, slot 18 (left) and slot 19 (right). Controller modules are not
designed for installation in any other slot.

The 8265 Controller module bay accommodates up to two Controller modules. Install at least one
Controller module for normal 8265 operation. Install a second Controller module to achieve Controller
module fault-tolerance.

Note: The second Controller module can only act as a backup for another Controller module. It cannot

act as a backup for a CPSW2 module using integrated power control.

Considerations When Installing Two Controller Modules

When two controller modules are to be installed, which module becomes the active depends on whether
the 8265 is powered on or not.

 If the 8265 is not powered on, the controller module installed in slot 18 will become the active one

(and the module in slot 19 will become the standby module) when the 8265 is powered on, regardless
of the order in which they are installed.

 If the 8265 is already powered on, the first controller module to be installed will become the active

one, irrespective of the slot used. It will also remain the active one when the second module is
installed later.

Installing the Module

To install a Controller module:

1. Remove the Controller module from the shipping carton.

2. Remove the Controller module from the anti-static bag and inspect it for damage. If the module

appears to be damaged, put it back in the anti-static bag, place it in the shipping carton, and contact
your local supplier.

3. Record the serial number and software version of your Controller Module. (Once the switch is

operational, you can view this information by entering the SHOW INVENTORY command at the
terminal prompt.)

4. If the controller slot is covered by a blank faceplate, remove the faceplate by turning the two

spring-loaded screws that hold the faceplate in place, counterclockwise. The Controller bay is located
at the lower right front corner of the switch.

Note: Each 8265 Controller module is equipped with an ejector that helps you to remove the

Controller module. This ejector can be in any position when you install the Controller module.

Figure 16 on page 34 shows how to insert a Controller module.

Chapter 5. Installing Modules 33

Slide the Controller
Module into the
selected slots as
shown here.

Figure 16. Installing a Controller Module

5. Lock the ejector into place by applying pressure to the Controller module faceplate with one hand as
you pull up on the end of the ejector. Ensure that the Controller module remains fully seated in the
backplane connector as you close the Controller module ejector.

6. Lift the end of the ejector until the ejector locks into place.

7. Complete the installation by hand-turning each of the spring-loaded screws at the top and bottom of
the module in a clockwise direction. Do not overtighten the screws.

8. If you are using the Controller module(s) in conjunction with the CPSW2 module(s), make sure that
the FORCE RCTL jumper on the CPSW2 module is set to the ON position (on both CPSW2 modules
if two are installed).

Attention: To ensure adequate cooling airflow, install blank slot cover plates over

all

empty slots.

34 IBM 8265: Installation Guide

Guidelines for Installing 8265 Media Modules

Before installing a media module, refer to the module-specific installation instructions that accompany your
module (See the Media Module Reference Guide). Some media modules require the installation of
daughter cards before the module is installed in the switch).

Note: It is not necessary to power down the switch when installing or removing media modules. You can

install or remove all media modules without disrupting switch operation.

This section describes guidelines for installing media modules. This section contains the following topics:
 Cautionary guidelines
 Installation guidelines

 Guidelines for installing 8260 ATM media modules

Observe these guidelines when handling, installing, or removing an ATM module.

Cautionary Guidelines

Before you begin to install a module, review the following guidelines when handling a module:

 Electrostatic discharge (ESD) can damage static-sensitive devices on circuit boards:

– Do not remove the module from its anti-static shielding bag until you are ready to install it.
– To ensure that static charge is removed, touch any installed module's fastener screw before

installing the module. This dissipates charge energy through the chassis to the grounded power
cord.

– Handle the module by the faceplate only.

 Do not twist or otherwise force modules into the switch.

Chapter 5. Installing Modules 35

Installation Guidelines

This section describes guidelines to follow when installing media modules.

1. 8265 media modules can be installed in slots 1–8 and 12–17. Slots 9, 10, and 11, are reserved for
Control Point and Switch modules.

Note: Slot 12 can be only be used in the following circumstances:

a. No CPSW module is installed in slot 11.
b. If the CPSW2 module is installed, the 8265 must be equipped with the backplane Part

Number 26L0112. Release 4 versions of the 8265 are equipped with this backplane. Older
versions of the 8265 are equipped with backplane Part Number 13J8689 and do not
support media modules in slot 12. The backplane part number can be displayed by
entering the the SHOW INVENTORY VERBOSE command. Alternatively, look for "Release
4" on the label to the left-hand side of the power supplies.

Table 3 lists the 8265 media modules that can be installed.

Table 3. Media Module Slot Availability

1-port 622 Mbps (MMF) 6511
1-port 622 Mbps (SMF) 6512
WAN 2.5 6561
MSS Server 2.5 5401

2. When deciding which available slot to use, consider the following:

 If you intend to also install 8260 ATM modules, note that they can only be installed in slots 1, 3, 5,

and 7. See Table 4 on page 37 for the slot widths of the 8260 modules. Make sure that adjacent
slots are also available if you are installing a 2– or 3–slot module.

Note: 8260 modules can only operate in the 8265 when the standard CPSW module is installed.

They will not operate when the enhanced CPSW2 module is installed.

 The media module slots are divided into three heat management areas:

– Slots 1 through 8
– Slots 6 through 13
– Slots 10 through 17.

If an overheat condition is detected (due to a fan failure, for example), then modules within that
area are selectively powered down, according to their power class settings, until the temperature
falls below the overheat threshold (how to set power class settings for modules is described in the

8265 Nways ATM Switch User's Guide

).

You should therefore install your most important modules in different management areas.

3. When installing a media module on which daughter cards are installed, take special care to insert the
host module straight into the slot. This ensures that daughter cards attached to the host module are
not damaged during host module installation.

36 IBM 8265: Installation Guide

4. To assure proper installation, match the top and bottom board guides as you slide the module cleanly

into place. Do not attempt to push the module all the way into the switch until you verify that module
ejectors are open.

Note: If the 8265 is powered on, the Error LED on the 4-port 155 Mbps and 1-port 622 Mbps modules

will illuminate when the module is installed. This is because the module detects that there is no
signal present, as there is no cable connection to the module's port(s) at this time. The LED will
extinguish once a connection is made.

Guidelines for Installing 8260 ATM Media Modules

1. 8260 media modules can only operate in the 8265 when the standard CPSW module (Feature Code

6501) is installed. They will not operate with the enhanced version of the CPSW module (Feature
Code 6502).

2. 8260 media modules must only be installed in slots 1, 3, 5, and 7.

Slots 7 can only be used for a 3–slot module when there is no CPSW module installed in slot 9.

3. Some 8260 media modules must have a minimum FPGA level in order to operate in the 8265. The

modules must have this FPGA level, or higher, before being installed in the 8265.
If your 8260 module does not have the specified FPGA level (or higher), upgrade the module before

removing it from the 8260, using MES 5099. For information on how to upgrade FPGA code, refer to

IBM 8260 Nways Multiprotocol Switching Hub, ATM Control Point and Switch Module Installation and
User's Guide

Chapter 6. Attaching a Configuration Console

You must attach an ASCII-type terminal to the RS-232 console port on the active CPSW module in order
to perform the initial configuration of the 8265. The connection can either be local or via modem.

If you use the modem cable delivered with the 8265 (Part Number 59G0278), you must also use the
supplied null modem adapter (Part Number 58F2861).

When the EIA-232 terminal attachment has a male connector, the gender changer (Part Number
58G4422) must be used.

1. Verify that the console and modem (if used) meet the factory defaults of the CPSW module. If they are

not compatible, you will not be able to communicate with the module. The default settings are:

 9600 baud rate
 8 data bits

 No parity

 1 stop bit.

2. Attach one end of an RS-232 cable to the 9-pin RS-232 console port on the front panel of the CPSW

module). Loop the cable through the Cable Management Tray (if installed) and attach the other end
(9-pin or 25-pin) into the appropriate port on the device.

3. After attaching a console to the CPSW RS-232 console port, make sure that the console is set up for

asynchronous serial communication.
How to set up the configuration console and enter command is described in the

Switch User's Guide

4. After connecting a modem to the console port, configure the modem by following the steps given in

the next section.

Configuring the Modem

The CPSW module supports the use of dial-in modems with the following requirements:

 The modem must be 100% Hayes-compatible
 Any valid baud rate (300, 1200, 2400, 9600, 19200) may be used. 9600 is recommended.
 The modem must be set to Dumb/Auto Answer mode.

To configure a modem, enter the following commands from the console to which the modem is attached:

1. Type at&F and press Enter (to restore the factory default settings).

2. Type at&dð and press Enter (to ignore changes in DTR status) If you have enabled automatic modem
hangup with the SET TERMINAL HANGUP ENABLE command and want to keep this setting, enter
at&d2and press Enter. This sets the DTR parameter so that hangup remains enabled when DTR
switches from ON to OFF.

3. Type atsð=1 and press Enter (to auto-answer on the first ring).

4. Type atsð? and press Enter (to verify the auto-answer if 001 is returned).

5. Type atq1 and press Enter (to ignore the result codes).

6. Type at&W and press Enter (to save the configuration changes).

7. Type at&Y and press Enter (to define the configuration as the new default).

8. Set the modem to Dumb mode (with command recognition disabled) by following the instructions in
the modem's user guide.

Verifying Your Installation

This section explains how to check that each component of the 8265 is correctly installed:

 Power supply units
 Fan units
 Controller module

 Control Point and Switch module
 Configuration console.

Refer to the Media Module Reference Guide for information on media modules.

Chapter 7. Completing the Installation 47

Verifying Power Supply Operation

To verify normal operation of an installed power supply or supplies, confirm that a power supply fault is not
indicated by checking the Power Supply LEDs.

There are four Power Supply LEDs, one for each power supply. These LEDs are located on the front
panel of the Controller modules and CPSW2 modules. Depending on your installation you should check
the LEDs on:

 On the Controller module if you are using the standard CPSW module or the CPSW2 module with

integrated power control disabled (FORCE RCTL jumper set to ON on the CPSW2 module). If you

have two Controller modules installed, you should check the LEDs on the active module.

 On the CPSW2 module if you are using the integrated power management functions (FORCE RCTL

jumper set to OFF on the CPSW module). If you have two CPSW2 modules installed, you should

check the LEDs on the active module. If you have CPSW2 modules installed, but have disabled power

management, you must check the LEDs on the active Controller module.

The LEDs are numbered 1 through 4, with 1 indicating the left-most power supply bay, and 4 indicating
the right-most power supply bay.

The LED for each unit installed should be lit. If any of the LEDs blinks or does not light for each installed
power supply when the 8265 is powered up, refer to Appendix A, “Troubleshooting” on page 55.

48 IBM 8265: Installation Guide

Verifying Fan Operation

To verify that all fan units are operating normally:

 Visually inspect all fans, making sure that each is turning without interruption.

 Check that a fan fault is not indicated by checking the FAN LEDs. There are three FAN LEDs, one for

each fan unit. These LEDs are located on the front panel of the Controller modules and CPSW2
modules. Depending on your installation you should check the LEDs:

– On the Controller module if you are using the standard CPSW module or the CPSW2 module with

integrated power control disabled (FORCE RCTL jumper set to ON on the CPSW2 module). If you
have two Controller modules installed, you should check the LEDs on the active module.

– On the CPSW2 module if you are using the integrated power management functions (FORCE

RCTL jumper set to OFF on the CPSW2 module). If you have two CPSW2 modules installed, you
should check the LEDs on the active module. If you have CPSW2 modules installed, but have
disabled power management, you must check the LEDs on the active Controller module.

Each FAN LED should be on. If the LED is off or blinking, refer to Appendix A, “Troubleshooting” on
page 55.

 Check that the Temp LED (on the active Controller module or the active Advantage CPSW module,

depending on which is being used for power management) is off, indicating normal 8265 internal
operating temperature.

If the LED is blinking or on, it indicates excessive internal operating temperature. This may mean that:

– One or more fans are not functioning normally
– Ventilation holes are blocked
– Fan exhaust temperature (internal 8265 operating temperature) is above 60 °C, (140 °F).

Fan exhaust temperature

each exhaust fan. Heat produced by circuit boards and power supplies accounts for most of this
warm air. Fan exhaust temperature is measured by a temperature sensor located at the rear of
each fan unit

is the temperature of air inside the 8265 as it passes out the back of

Chapter 7. Completing the Installation 49

Verifying Controller Module Operation

To verify Controller module operation:

1. Press the LED test button and check that all LEDs illuminate. Then release the LED test button.
Repeat for the second Controller module if two are installed.

2. Check the STBY (Standby) and Active LEDs.

 If one Controller module is installed, check:

a. that the STBY LED is off
b. that the Active LED is on
c. that the Power Supply LED is on for each power supply unit installed
d. that the FAN LEDs are on
e. that the Temperature LED is off.

 If two Controller modules are installed, check:

– that the Active LED on the active Controller module is on.
– that the STBY LED on the active Controller module is off.
– that the Active LED on the standby Controller module is off.

– that the STBY LED on the standby Controller module is on.
If any of the LEDs fail the above checks, refer to Table 8 on page 55.

Verifying Control Point and Switch Module Installation

You can verify that the Control Point and Switch module is correctly installed by checking the front panel:

 The CPU Stop LED should be off.
 When the 8265 is powered on (or reset), the Control Point and Switch module is initialized and the

System Status LCD displays the various steps of the initialization

1. INIT - initialization process is running.

2. If diagnostics are enabled, the following steps are shown while testing the first bank of DRAM
memory

– SET1, RFW1, RBW1, BRST.

3. CLR1 - first DRAM memory bank is being cleared.

4. If diagnostics are enabled, the following steps are shown while testing the second bank of DRAM
memory (if installed):

– SET2, RFW2, RBW2, BRST.

5. CLR2 - second DRAM memory bank is being cleared (if installed).

6. LOAD - operational code is being copied from the PCMCIA card into the DRAM.

Once the initialization has completed successfully, the System Status LCD will show either ACTV (on
the active CPSW module) or STBY (on the standby Control Point and Switch module when two are
installed). If neither are displayed, an error was encountered during initialization process:

– If the error was not critical, the code goes in Maintenance Mode and an error code and description

of the error is displayed.

– If the error was critical,---> ERROR is displayed. Press the Display Control button to view an

explanation of the error.

 (CPSW2 Module only)

– Press the LED Test button and check that all LEDs illuminate. Then release the button. Repeat on

the second CPSW2 module if two are installed.
If no LEDs are illuminated, power off the 8265, remove the CPSW2 module and check that the

FORCE RCTL jumper is in the correct position:

- OFF (down), if you are using the integrated power control

- ON (up), if you are using Controller modules for power control. Check also that you have at
least one Controller module installed.

If you have two CPSW2 modules installed, check that the jumper setting is the same on both
modules.

– If you are using the integrated power control, on the active CPSW2 module:

- Check that the Power Supply LED is on for each power supply unit installed

- Check that the FAN LEDs are on

- Check that the Temperature LED is off.

If any of the LEDs fail the above checks, refer to Table 8 on page 55.

Specific CPSW2 Module Problems

Problems may occur when a CPSW2 module is installed with an incorrect power control jumper (FORCE
RCTL) setting. The setting is incorrect if:

 The jumper is set to ON (up) and no controller module is installed.
 The jumper setting differs from that of an already installed CPSW2 module.

The problems may occur:

 after powering on the 8265
 when inserting the CPSW2 module while the 8265 is powered on (hot-plugging).

To avoid these problems, you must ensure that the jumper setting on the CPSW2 module being installed
is correct, and, if applicable, matches that of the currently installed module. To check the current setting
on the active CPSW2 module without removing the module, enter the SHOW POWER ALL command.

Problems After Power-On

1. If a CPSW2 is installed with the FORCE RCTL jumper set to ON (up), and no Controller module is
installed:

 The LEDs on the CPSW2 module will not illuminate, even when the TEST LED button is pressed.
 Media modules cannot be connected to the network or enabled.

To resolve this problem you must:

a. Power off the 8265.

b. Either:

 Install a Controller module should you not wish to use the integrated power control of the

CPSW2 module, or

 Remove the CPSW2 module and move the jumper to the OFF (down) position. Then re-install

the module

c. Power on the 8265.

2. When two CPSW2 modules are installed with different jumper settings:

 If the active CPSW2 module has an incorrect jumper setting:

– The LEDs on the (newly) active CPSW2 module will not illuminate, even when the TEST LED

button is pressed.

– Media modules cannot be connected to the network or enabled.

This occurs regardless of the setting on the second (standby) CPSW2 module.

 If the standby CPSW2 module has an incorrect jumper setting:

– The 8265 will be operational provided that the active CPSW2 module's jumper position in the

correct (ON if Controller module installed). However, the 8265 will not be able to switch to the
backup CPSW2 module. When this is attempted:

- The LEDs on the (newly) active CPSW2 module will not illuminate, even when the TEST
LED button is pressed.

- Media modules cannot be connected to the network or enabled.

Should this problem occur, you must

a. Power off the 8265

Appendix A. Troubleshooting 57

b. Remove the CPSW2 that has the incorrect jumper setting
c. Set the jumper to the correct position
d. Re-install the CPSW2 module
e. Power on the 8265.

Problems When Hot-Plugging: When installing CPSW2 modules into an already powered-on

8265, the following problems will occur if the power control jumper is in the incorrect position:

1. If the jumper is set to the ON (up) position, and you do not have a Controller module installed:

 The LEDs on the CPSW2 module will not illuminate, even when the TEST LED button is pressed.
 Media modules cannot be connected to the network or enabled.

To resolve this problem you must:

a. Power off the 8265.

b. Either:

 Install a Controller module should you not wish to use the integrated power control of the

CPSW2 module, or

 Remove the CPSW2 module and move the jumper to the OFF (down) position. Then re-install

the module

c. Power on the 8265.

2. If the jumper is set to the OFF position, but a Controller module is already installed:
a. Power off the 8265.

b. Either:

 Install a Controller module should you not wish to use the integrated power control of the

CPSW2 module, or

 Remove the CPSW2 module and move the jumper to the OFF (down) position. Then re-install

the module

c. Power on the 8265.

 The CPSW2 module cannot take over power control from the Controller module.
 Media modules cannot be connected to the network or enabled.

To resolve this problem you must:

a. Power off the 8265.

b. Either:

 Remove the Controller module, should you wish to use the integrated power control functions

of the CPSW2 module, or

 Remove the CPSW2 module and move the jumper to the ON (up) position. Then re-install the

module

following maintenance procedures are discussed:

 Routine Maintenance

 Replacing a Defective Power Supply
 Replacing a Defective Fan Unit
 Replacing a Defective Controller module.

Note: There are no user-serviceable parts on either the load-sharing power supplies or the fan units. If

these components fail, remove them as described in this Appendix and return them to your
supplier. Keep replacement power supply units and fan units at your site so they are available if
needed.

 Copyright IBM Corp. 1994, 1998 59

Routine Maintenance

On a regular basis, inspect your 8265 to verify that:

 All blank 8265 faceplates are securely attached to the chassis.
 At least two fans are running.

Attention: If only two fans are operational, system operation is not affected. However, you should
schedule the defective fan for prompt replacement. If fewer than two fans are operational, power off
the 8265 immediately. Do not attempt to power on again until at least two operational fans have been
installed. You should normally run the 8265 with a full complement of three fans.

 Ventilation to the 8265 is unobstructed.
 CPSW module, Controller module (if installed), and media module LEDs are functioning normally and

show normal readings.

 All modules are securely seated in the backplane and firmly attached to the chassis.
 Power requirements for all installed modules are met by the power supplies.
 Power cords from each power supply are not frayed or damaged.
 Cables running from each installed module are in good condition.
 If rack mounted, the 8265 and the cable tray are securely attached to your rack.

60 IBM 8265: Installation Guide

Replacing a Defective Power Supply

This section describes how to replace the following:

 AC Power Supply
 -48 Volt DC Power Supply.

The 8265 can accommodate up to four modular load-sharing AC or DC power supplies.
Note: When replacing a power supply, you must leave enough supplies running at all times to satisfy the

requirements of installed modules. If removal of a defective, but still functioning, power supply will
not cause a power deficit in the 8265, you can remove the faulty supply without losing power to a
module or modules. Before attempting to remove a power supply from the chassis, enter the
SHOW POWER BUDGET command to display current power conditions for the 8265.

Appendix B. Maintenance 65

Replacing a Defective Fan Unit

This section describes how to replace defective fans for the 8265.
The 8265s are shipped with three installed fan units (Part Number 25H1798). For normal operation, at

least two of these dedicated fan units must be running at all times. Power supply fans help to ventilate the
8265, but they are not designed to act as a substitute for dedicated fan units.

Attention: If more than one fan unit malfunctions, power off the 8265 immediately and do not attempt to
power up again until you have installed at least two fully functional fan units. To ensure optimal 8265
operation, always run the 8265 with a full complement of three fan units.

If only one fan unit malfunctions, you do not need to power off the 8265 before removing and replacing the
defective unit.

To replace a defective fan unit:

1. Remove and save the four corner screws that attach the fan unit to the rear of the 8265.

2. Carefully pull the fan unit straight out from the 8265 fan bay and, before completely removing the fan,
grasp the four-position fan connector cable and disconnect it from the 8265 (see Figure 23).

Figure 23. Replacing a Defective Fan Unit

3. Remove the replacement fan unit from its shipping box and carefully slide the fan into the slot formerly
occupied by the faulty unit. Connectors on the installed fan must be firmly seated in the corresponding
8265 connectors.

Note: The fan begins rotating the moment the unit is plugged in.

4. Verify that the replacement fan is flush with the back of the 8265.

5. Replace the four screws that secure the fan unit to the rear of the 8265.

6. Visually inspect all installed fans to verify that each is turning without interruption.

66 IBM 8265: Installation Guide

7. Check the Fan LEDs (on the active Controller module, if installed, or active CPSW2 module) to

confirm that all fan units are indeed functioning normally. LEDs for installed fans should be illuminated
to indicate normal operation.

Appendix B. Maintenance 67

Replacing a Defective Controller Module

Note: In a switch with two installed Controller modules, removal of the active Controller module causes a

fast reset (the standby Controller module becomes the active Controller module). In a switch with
one installed Controller module, removal of the Controller module causes the switch to go down.

To remove a Controller Module:

1. Loosen the screws at the top and bottom of the module faceplate until the screws disconnect from the
switch.

2. Grasp the end of the module ejector at the lower left corner of the faceplate, and pull it down. This
action causes the ejector to exert pressure on the switch, forcing the Controller Module out of the slot
so its faceplate can then be grasped.

3. Grasp the faceplate and pull the Controller module straight out of the slot.
Note: If you have a standby Controller module installed, make sure the Standby LED (STBY) is ON

before attempting to remove the active Controller module.

To insert a replacement module, see page 33.

Product Page/Warranties

The following paragraph does not apply to the United Kingdom or to any country where such
provisions are inconsistent with local law.

INTERNATIONAL BUSINESS MACHINES CORPORATION PROVIDES THIS PUBLICATION "AS IS" WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

Some states do not allow disclaimer of express or implied warranties in certain transactions, therefore this
statement may not apply to you.

 Copyright IBM Corp. 1994, 1998 69

Statement of Limited Warranty

The warranties provided by IBM in this Statement of Limited Warranty apply only to Machines you
originally purchase for your use, and not for resale, from IBM or an IBM authorized reseller. The term
"Machine" means an IBM machine, its features, conversions, upgrades, elements, or accessories, or any
combination of them. Machines are subject to these terms only if purchased in the United States or Puerto
Rico, or Canada, and located in the country of purchase. If you have any questions, contact IBM or your
reseller.

Production Status

Each Machine is manufactured from new parts, or new and serviceable used parts (which perform like
new parts). In some cases, the Machine may not be new and may have been previously installed.
Regardless of the Machine's production status, IBM's warranty terms apply.

The IBM Warranty

IBM warrants that each Machine 1) is free from defects in materials and workmanship and 2) conforms to
IBM's Official Published Specifications. IBM calculates the expiration of the warranty period from the
Machine's Date of Installation. The date on our receipt is the Date of Installation, unless IBM or your
reseller informs you otherwise.

During the warranty period, IBM or your reseller will provide warranty service under the type of service
designated for the Machine and will manage and install engineering changes that apply to the Machine.
IBM or your reseller will specify the type of service.

For a feature, conversion, or upgrade, IBM or your reseller may require that the Machine on which it is
installed be 1) the designated, serial-numbered Machine and 2) at an engineering-change level compatible
with the feature, conversion, or upgrade. Some of these transactions (called "Net-Priced" transactions)
may include additional parts and associated replacement parts that are provided on an exchange basis. All
removed parts become the property of IBM and must be returned to IBM.

Replacement parts assume the remaining warranty of the parts they replace.
If a Machine does not function as warranted during the warranty period, IBM or your reseller will repair or

replace it (with a Machine that is at least functionally equivalent) without charge. If IBM or your reseller is
unable to do so, you may return it to your place of purchase and your money will be refunded.

If you transfer a Machine to another user, warranty service is available to that user for the remainder of
the warranty period. You should give your proof of purchase and this Statement to that user.

70 IBM 8265: Installation Guide

Warranty Service

To obtain warranty service for the Machine, you should contact your reseller or call IBM. In the United
States or Canada, call IBM at 1-800-IBM-SERV (426-7378). You may be required to present proof of
purchase.

Depending on the Machine, the service may be 1) a "Repair" service at your location (called "On-site") or
at one of IBM's or a reseller's service locations (called "Carry-in") or 2) an "Exchange" service, either
On-site or Carry-in.

When a type of service involves the exchange of a Machine or part, the item IBM or your reseller replaces
becomes its property and the replacement becomes yours. The replacement may not be new, but will be
in good working order and at least functionally equivalent to the item replaced.

It is your responsibility to:

1. Obtain authorization from the owner (for example, your lessor) to have IBM or your reseller service a

Machine that you do not own.

2. Where applicable, before service is provided:

a. follow the problem determination, problem analysis, and service request procedures that IBM or

your reseller provide,
b. secure all programs, data, and funds contained in a Machine,
c. inform IBM or your reseller of changes in a Machine's location, and
d. for a Machine with exchange service, remove all features, parts, options, alterations, and

attachments not under warranty service. Also, the Machine must be free of any legal obligations or

restrictions that prevent its exchange; and

3. Be responsible for loss of, or damage to, a Machine in transit when you are responsible for the
transportation charges.

Extent of Warranty

IBM does not warrant uninterrupted or error-free operation of a Machine.
Misuse, accident, modification, unsuitable physical or operating environment, improper maintenance by

you, or failure caused by a product for which IBM is not responsible may void the warranties.
THESE WARRANTIES REPLACE ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING,

BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. HOWEVER, SOME LAWS DO NOT ALLOW THE EXCLUSION OF IMPLIED
WARRANTIES. IF THESE LAWS APPLY, THEN ALL EXPRESS AND IMPLIED WARRANTIES ARE
LIMITED IN DURATION TO THE WARRANTY PERIOD. NO WARRANTIES APPLY AFTER THAT
PERIOD.

In Canada, warranties include both warranties and conditions.
Some jurisdictions do not allow limitations on how long an implied warranty lasts, so the above limitation

may not apply to you.

Appendix C. Notices 71

Limitation of Liability

Circumstances may arise where, because of a default on IBM's part (including fundamental breach) or
other liability (including negligence and misrepresentation), you are entitled to recover damages from IBM.
In each such instance, regardless of the basis on which you are entitled to claim damages, IBM is liable
only for:

1. Bodily injury (including death), and damage to real property and tangible personal property; and

2. The amount of any other actual loss or damage, up to the greater of $100,000 or the charge for the
Machine that is the subject of the claim.

Under no circumstances is IBM liable for any of the following:

1. Third-party claims against you for losses or damages (other than those under the first item listed
above);

2. Loss of, or damage to, your records or data; or

3. Economic consequential damages (including lost profits or savings) or incidental damages, even if IBM
is informed of their possibility.

Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you.

This warranty gives you specific legal rights and you may also have other rights which vary from
jurisdiction to jurisdiction.

NEBS Certification

The IBM 8265 Nways ATM Switch has successfully completed testing and evaluation by Bell
Communications Research, Inc, (Bellcore) and has met all requirements for NEBS certification. The
Bellcore analysis determines a device's environmental compatibility and acceptability for applications in
telco central office environments. The telecommunications industry considers NEBS certification a major
prerequisite for the selection of vendor products to be used in central offices. NEBS certification is also
viewed by procurers of private network equipment as an indicator of a product's industrial strength and
robustness.

Bellcore's NEBS evaluation addresses two key areas of environmental compatibility:

1. Electromagnetic compatibility criteria in the areas of:
 electrostatic discharge
 electromagnetic interference

 lightning and AC power faults
 electrical safety, bonding, and grounding.

2. Physical compatibility criteria in the areas of:

 thermal and fire resistance
 earthquake and office vibration
 transportation and handling

 acoustic noise.

Criteria are defined at three levels: desirable features and functions, conditional requirements, and
mandatory requirements being the most stringent. The 8265 has satisfied the highest level of criteria for all
attempted tests. These tests represent the exhaustive list of NEBS tests for level 3 certification with the
exception of "airborne contaminants". IBM will consider attempting the airborne contaminants test in the
future if required for specific application.

NEBS certification now gives both telco and private network customers the assurance that the 8265 can
meet the requirements of the most demanding segment of networking industry.

In addition to the 8265 chassis itself, the following components have, at the time of publication, received
NEBS certification:

 CPSW2 module (Feature Code 6502)
 Controller module (Feature Code 8000)
 415 W AC power supply (Feature Code 8027)
 295 W DC power supply (Feature Code 8028)
 WAN 2.5 module (Feature Code 6561)
 MSS Server 2.5 module (Feature Code 5401)
 155 Mbps multimode fiber daughter card (Feature Code 6580)
 155 Mbps singlemode fiber daughter card (Feature Code 6581)
 E1/T1/J1 daughter card (Feature Code 6570)
