Remove cable chains

You remove both cable chains so you can remove and replace a failed drive drawer. The left and right cable
chains allow the drawers to slide in and out.
Before you begin
• You have issued the Set Drawer Attention Indicator CLI command, or you have stopped host I/
O activity and powered off the drive shelf and controller shelf.
• You have an ESD wristband, or you have taken other antistatic precautions.
• You have a flashlight.
About this task
Each drive drawer has left and right cable chains. The metal ends on the cable chains slide into corresponding
vertical and horizontal guide rails inside the enclosure, as follows:
• The left and right vertical guide rails connect the cable chain to the enclosure's midplane.
• The left and right horizontal guide rails connect the cable chain to the individual drawer.
Attention: Possible hardware damage — If the drive tray is powered on, the cable chain is energized
until both ends are unplugged. To avoid shorting out the equipment, do not allow the unplugged
cable chain connector to touch the metal chassis if the other end of the cable chain is still plugged in.
Procedure
1. From the rear of the drive shelf, remove the right fan canister:
a) Press the orange tab to release the fan canister handle.
