Removing and Installing Power Supplies
The power supplies are hot-swappable. You do not need to remove AC power before removing or
installing a power supply.
However, if you remove a power supply with the power on, the server must have a redundant power
supply configuration. In this server system, three power supplies are required for N+1 redundancy.
Otherwise, an overload condition might occur and cause the server to shut down.
CAUTION: Use only hand tools when inserting or removing a power supply. Do not use power tools.

1.
