About power supply maintenance guidelines
Follow these guidelines for maintaining power supplies:

supply is installed and connected to power.
■ For proper cooling, do not leave a power supply slot open. Do not remove a power supply until you
are ready to replace it.
■ A server can operate with only one functioning power supply. However, replace a failed or failing
power supply as soon as possible.
