Replacing and Adding System Components
Power supplies
The Gateway 7400 Server uses a redundant power supply offering fault 
tolerance and hot-swap capability. This section describes replacing the power 
supply and also describes the procedure for hot-swapping a power supply 
module.
Replacing a redundant power supply module
If one of the two power supply modules fails, the other module can support 
the system while the failed module is replaced. An audible alarm indicates a 
failed module, 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 (on the back of the power supply modules) turns off when the 
module fails.
2
Loosen the thumbscrew that secures the power supply module to the back 
panel.
