Each
Controller has a pair of power supplies that are located at the back of the
Controller. Power supplies are customer replaceable units (CRUs). Replacing a power supply does not require you to bring the
Controller offline, provided that the other power supply is online and working. The following figure identifies the location of the
Controller power supplies.

1 Power supply-1 (PS-1) |
2 Power supply-0 (PS-0) |
Note: To replace a power supply, you can access the faulted power supply from the back of the Controller module. To access the power supply located in the bottom slot (PS-0), the CMA clip must be disconnected to enable the power supply to clear the support arm.
Note: Replacing the power supply does not require you to slide the Controller into the extended rack position and can be performed while the Controller is in the rack position.
Note: Ensure that the power strain relief strap on the power supply is positioned correctly such that there is proper clearance and the power supplies can be re-inserted into the power supply compartment without interference.
Note: Ensure that the power cable is routed correctly and there is no interference with the Controller chassis.
Important! Do not remove the failed power supply until you have a replacement power supply to ensure proper airflow in the Controller.
Note: For fan replacement, the
Replaceable Unit list displays the names of each fan. Each power supply contains one fan, and each fan module contains two fans. If a fan fails in a power supply, replace the power supply. If a fan fails in a fan module, replace the fan module. The following list identifies the names of the fans and the corresponding customer replaceable unit (CRU).
