Power Cooling Module Replacement
This section describes how to replace the power cooling module.
Identify the failed power supply unit
Before you begin
Before you begin the replacement procedure, make sure you have correctly identified the failed
part, and that a replacement is available and unpacked and ready to install within the two-minute
limit.
CAUTION
To prevent overheating, you must replace a power/cooling module within two
minutes. If you do not, the storage enclosure may power down all of the disks, causing the
system to lose access to the disks.
When replacing a power/cooling module, make sure the green LED on one module has been
steadily on for at least 5 seconds before removing power from the second module.
Procedure
1. Check the service LED on the affected power supply unit.
