Chapter 5 Chassis Maintenance
Like all computer systems, you will need to perform some routine
maintenance tasks. Some of these include making sure that the air
vents in the chassis are clear of obstructions and that the cooling air
from the fans flows freely. You will also need to check the foam filter
behind the front panel to ensure it is clean, thus allowing for unrestricted
air flow to the fans. You should always keep an eye on all cables to
make sure they are not damaged and are securely connected.
Occasionally, you should remove the chassis cover and check for loose
cards, and remove any dust build-up.
Always to remember to power down your computer and then the
expansion system BEFORE you attempt to perform any maintenance
tasks.
In spite of regular performance of routine maintenance tasks, some
computer systems can experience hardware failures. Fortunately, your
investment in a P13RR provides you with the ability to easily replace the
power supply in the event of power supply failure.
“Hot-Swappable” Power Supply
The redundant power supply includes
two hot-swappable modules that share
the power load requirements during
normal operations. Should one module
fail for any reason, the power load will be
shifted to the other module and sound an
audible alarm.
If a power supply fails, an alarm will
sound to alert you of the problem. Press
the square red button adjacent to the
power supply to stop the audible alert.
To replace a failed power supply, simply
grab the handle, press down on the release lever at the top of the
module, and pull. Replace the failed module with a new one and turn on
the power to the module using the power switch at the bottom of the
module. The power load will again be shared between these two
modules.
