Remove a Power Supply
Caution - If a power supply fails and you do not have a replacement available, ensure proper
airflow by leaving the failed power supply installed in the server until you replace it with a new
power supply.
This procedure describes how to remove a power supply from the server.
Before You Begin ■
For serviceability considerations, see “Component Serviceability” on page 66 .

The server can be configured to use low‑line 110VAC input voltage in a 2-processor
configuration, however 4-processor configurations require power supplies to be configured
with high‑line 220VAC input.
