The power unit fault indicator ( ) lights up amber if the power
supply unit fails/downgrades, while the fan fault indicator ( )
lights up amber if a cooling fan fails/downgrades.
NOTE: The buzzer sounds and continues to sound when the
pair of redundant fans both fail at the same time.
If one module of the redundant cooling fan modules or EPS-R
modules fails, the server can be kept running without shutdown
until a service person arrives. (Downgraded operation)
If two modules of the redundant cooling fan modules or EPS-R
modules fail, the server must be shut down immediately. (Faulty
condition)
Before asking for inspection and repair, check the operating
condition of the server with the system status indicators and the
server monitoring software. When using Windows Server 2003 /
Windows 2000, faulty locations can be confirmed in detail using
the server monitoring software.
Failure of the fan installed on the EPS-R module includes EPS-R
module failures.
NOTE: In case two modules of the redundant cooling fan
modules or EPS-R modules have failed at a time, shut down
and switch off the server immediately. Failure to do so might
result in the loss or corruption of important data and
programs.
Even if one module of the redundant cooling fan modules or
EPS-R modules fails, the other module keeps operating so
that the system will not shut down. (Downgraded operation)
However, if two modules of the redundant cooling fan
modules or EPS-R modules have failed at a time, important
data and programs might be lost or corrupted. To avoid this,
ask for repair as soon as possible.
Prolonged downgraded operation could shorten service life of
each system component, depending on the temperature and
installation conditions.
