The server has two power supplies. The two-power supply configuration ensures redundancy. This allows the server to operate when one of the power supplies fails. However when the server is operating on one power supply, redundancy no longer exists, and the risk for an unexpected shut down and a loss of data is high. When a power supply or any component that is part of a redundant configuration fails, replace it immediately.
Each power supply contains an indicator panel. The following indicators are lit when a power supply fault is detected:
Front and back Service Action Required indicators
Rear PS Fault indicator on the front bezel of the server
Service Action Required indicator on the faulty power supply
See Server Front Panel Features and Server Back Panel Features for locations of system indicators.
