Removing an I/O Module or Management Module
You need the following tools and equipment to remove a BlackDiamond 20800 series module:
● ESD-preventive wrist strap (if one is not already attached to the chassis)
● #2 Phillips screwdriver
● Anti-static packaging for the removed module
● Replacement module or module blank
CAUTION
If you remove a module, you must install a replacement module or a module blank to ensure that the remaining
modules continue to function correctly. All module slots must be occupied at all times for proper cooling and
module operation.

1 Attach the ESD-preventive wrist strap to your bare wrist and connect the metal end to the ground
receptacle on the top left corner of the chassis.
