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.
To replace a failed power supply module:
1 Determine which power supply module has failed. The module power
LED turns off when the module fails.
2 Loosen the thumbscrew that secures the power supply module to the back
panel.
