Each server has two hot plug power supplies. If a power supply fails, replace it as soon as possible.
Power supply maintenance guidelines
Follow these guidelines for maintaining power supplies:
• You can replace a power supply without disrupting operations if an alternate, functioning power 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.
• Replace a power supply only with a power supply of the same type and wattage. Contact Customer Support
(https://www.hpe.com/support/hpesc) for replacement power supplies.
