Indication of a failure

A power supply and cooling fan can be added to the EPS-R cage to make them
redundant. A redundant cooling fan has dual air-intake and exhaust fans, so if one fails,
the other will continue cooling down the system.
NOTE: The redundant fan is on standby under normal operating conditions and
goes into operation as soon as a problem is detected with the primary fan.
The power unit fault indicator lights amber if the second power supply fails, while the fan
fault indicator lights amber if either cooling fan fails.
If one of the redundant cooling fans or the EPS-R cage fails, the server can be kept
running in downgraded operation. If two or more modules fail, the server must be shut
down immediately.
EPS power supply
power supply. If the fan fails, system components can overheat, resulting in lost or
corrupted data and/or programs. To avoid system damage, shut down the server
immediately, then correct the faulty condition as quickly as possible.
EPS-R power supply cage
cooling fan fails, the remaining fan is sufficient to cool the power supply—allowing the
server to continue running in a "downgraded operational state". Depending on the
temperature and installation conditions, prolonged downgraded operation could shorten
the service life of each system component. If both EPS-R cage cooling fans fail, shut
down the server immediately and correct the faulty condition as quickly as possible.
Exhaust fan- The exhaust fan module comprises the primary exhaust fan and the
exhaust duct.
Intake fan- The server has two intake fan bays. If one module is installed with two fans,
and one of the intake fans fails, the server can overheat, resulting in lost or corrupted
data and/or programs. If two modules are installed and one module fails, the server will
continue running in a "downgraded operational state". Depending on the temperature
and installation conditions, prolonged downgraded operation could shorten the service
life of each system component. If both intake fans fail, shut down the server immediately
and replace the failed fans.
