Removing I/O Modules

Extreme Networks BlackDiamond 10K-Series Switch Installation Guide 61

Removing I/O Modules

All BlackDiamond I/O modules are hot-swappable. You do not need to power off the system to remove

a module. Complete the action of removing a BlackDiamond I/O module in a reasonable time frame. Be

sure to remove the module completely to avoid partial connection of backplane connectors.

NOTE

If you remove a BlackDiamond I/O module during traffic flow to the module, several error messages

might be written to the log immediately. These messages should cease to occur after 10 seconds.

Under this circumstance, the error messages can be safely ignored. The error messages might contain

one or more of the following:

04/13/1999 17:18.46 <DBUG:KERN> killPacket: HW pqmWaitRx failed

04/13/1999 17:18.46 <DBUG:KERN> pqmWaitKill failed. Card 1 is removed

You need the following tools and equipment to remove an I/O module:

• ESD-preventive wrist strap

• # 1 Phillips screwdriver

• Replacement I/O module or blank faceplate if you are not replacing the I/O module

To remove an I/O module:

1 Attach the ESD strap that is provided to your wrist and connect the metal end to the ground

receptacle that is located on the top-left corner of the switch front panel.

2 Use a #1 Phillips screwdriver to unscrew the two captive screws.

3 Simultaneously rotate the ejector/injector levers outward to disengage the module from the

backplane.

a Grasp the module front panel with one hand, and place your other hand under the metal panel to

support the weight of the module.

CAUTION

To prevent ESD damage, handle the module by the metal panel edges only. Never touch the

components on the PCB or pins on any of the connectors.

b Slide the module out of the chassis and place it immediately into an antistatic sack to protect it

from ESD damage and to prevent dust from collecting on the module’s connectors.

4 If you are not going to install a replacement I/O module, cover the slot with a blank faceplate.

Otherwise, follow the I/O module installation procedure on page 58.

5 Leave the ESD strap permanently connected to the chassis so that it is always available when you

need to handle ESD-sensitive components.

To remove additional I/O modules, repeat steps 1 through 4.
