9. Power off the shelves as follows:
◦ If you are replacing a drawer in a shelf with Drawer Loss Protection:
There is NO need to power off any of the shelves.
You can perform the replace procedure while the drive drawer is online, because the
Set Drawer
Service Action Allowed Indicator
CLI command completed successfully.
◦ If you are replacing a drawer in a controller shelf without Drawer Loss Protection:

b. Wait for all LEDs on the controller shelf to go dark.
◦ If you are replacing a drawer in an expansion drive shelf without Drawer Loss Protection:

b. Wait for all LEDs on the controller shelf to go dark.
c. Turn off both power switches on the drive shelf.
d. Wait two minutes for drive activity to stop.
Step 2: Remove cable chains
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.
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.
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.
Steps
1. Make sure host I/O activity has stopped and the drive shelf or controller shelf is powered off, or issue the
Set Drawer Attention Indicator CLI command.
2. From the rear of the drive shelf, remove the right fan canister:
a. Press the orange tab to release the fan canister handle.
The figure shows the handle for the fan canister extended and released from the orange tab on the left.
