most cases, the power supply fan itself is not field-replacable. If the power
supplies are removable modules, replacing the module replaces the fan.

Using GUI for Power Supply problems

On a fixed ATX power supply, if a cable is frayed, it can be shorting something
to ground. Also, it's possible for the connectors to be damaged (from repeated
plugging), and aren't effective enough in contacting the motherboard. If a cable
is broken, that could be a problem. Typically, the symptoms you would be
looking for on a power supply are unusually low or high voltages (or both). The
voltages read with by the Aurora's sensors are on the motherboard – if these
voltages are not correct, it could also indicate a power supply problem. On a
system with redundant power supplies, the power load is shared between the
power supplies, so if the voltages are off, it could indicate a problem with one
power supply, both, or the DC power distribution board. On systems with
removable power supplies, there is usually a buzzer on the DC power
distribution board which sounds if there is a voltage problem. Again, if there is
no power going in to one power supply on a dual-power supply system, the
buzzer may not sound, as there is no problem with the power supply – the DC
distribution board is just sending out power form one power supply instead of
two. Systems with removable power supplies have card-edge connectors
which contact the DC power distribution board. If this card-edge connector is
oxidized, scratched, or otherwise broken, it could cause a problem.

DC Power Distribution problems

On systems with removable power supplies, this is the board that the power
supplies plug into. Systems with single power supplies have less-complicated
DC Power Distribution Boards than ones with redundant power supplies. This
is because on the ones with redundant power supplies, the board has to
tolerate power surges if a power supply is hot-plugged. The board is fairly
simple – it usually either works or it doesn't. The connections to the
motherboard are prone to the same problems that the fixed power supplies
have, but additionally, they possess a delicate communication cable which
relays power supply status information to the motherboard. It is possible for
the connector(s) which contact the power supplies to be broken as well –
especially if someone tries to force a power supply in upside-down.

Chassis Problems

The chassis is an electromechanical system itself, which could present a
myriad of problems as follows:
Air Intakes/Exhaust: These should be periodically cleaned, as their blockage
could generate unnecessary heat inside the array.
