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 insertion or 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 following. 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 272.
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.
