Replacing and Adding System Components
Replacing a hot-swap power supply
If your system configuration includes three power supplies, it is possible to
hot-swap a failed power supply without shutting down your system. The
average configuration for this server is two power supplies (top and bottom).
Gateway does not recommend hot-swapping power supplies with this
configuration.
An audio alarm and front panel LED indicate if one of the power supplies
has failed. To determine which power supply has failed, look for an amber
Fail LED on the back of each power supply.
The Predictive Fail LED indicates if one of the power supplies has a fan or
cooling problem which would eventually cause a failure. This allows you to
replace the indicated power supply prior to an actual failure.
To replace a hot-swap power supply:
1
Determine which power supply needs to be replaced, based on the LED
indicators on the top of each power supply. If your system does not have
three power supplies, shut down your operating system and turn off the
system power.
2
Remove the four screws securing the power supply to the back of the
chassis.
Caution
Gateway does not recommend hot-swapping if your
system only has two power supplies. A single power
supply may overload if it does not have sufficient capacity
to provide power for your system as it is configured.
