If you plan to replace a power supply, keep the following
requirements in mind.
- You have a replacement
power canister that is supported for your controller shelf or drive
shelf model.
- You have one power canister
that is installed and running.
- You have an ESD wristband, or you have
taken other antistatic precautions.
You can replace a
power canister while your storage array is powered on and performing
host I/O operations, as long as the following conditions are true:
- The other power canister
in the shelf has Optimal status.
Note: While you perform the
procedure, the other power canister supplies power to both fans to
ensure that the equipment does not overheat.
- The OK to
remove field in the Details area of the Recovery Guru
in ThinkSystem System Manager displays Yes,
indicating that it is safe to remove this component.
Attention: If
the second power canister in the shelf does not have Optimal status
or if the Recovery Guru indicates that it is not OK to remove the
power canister, contact technical support.
