Power supplies
The Gateway 7210 Server supports two power supplies. The basic model uses
a single power supply of the same size and type as those used in most desktop
PCs. The optional upgrade provides an N+1 redundant power supply that
offers fault tolerance and hot-swap capability. This section describes replacing
both power supplies and also describes the procedure for hot-swapping a
power supply module in the N+1 redundant power supply.

Replacing a redundant power supply module
The redundant power supply offers fault tolerance and hot-swap capabilities.
If one of the two modules fails, the other module can support the system while
the failed module is replaced. A failed module is indicated by an audible alarm
and the corresponding power supply status LED will begin to flash. See “Front
panel” on page 2 for the location and complete information on the function
of the power supply status LEDs. You do not have to turn off the system to
replace the failed module.
