Lamp indication in case of the occurrence of an EPS-R cage
failure or cooling fan unit failure
A power supply module and cooling fan modules can be added to the EPS-R
cage and the cooling fan unit, respectively, to make them redundant. A
redundant cooling fan unit has dual air-intake fans and dual exhaust fans,
installed in line as shown below, so that, if one of their partner fans fails, the
other fan will continue to cool down the system.
Locations of cooling fans
In case the EPS-R cage or the cooling unit fails, the buzzer sounds and the Fault
lamp (
) lights up to give a warning of it.
If one module of the redundant cooling fan unit or EPS-R cage fails, the server
can be kept running without shutdown until a service person arrives.
(Downgraded operation)
If two or more modules of the redundant cooling fan unit fail, the server must
be shut down immediately. (Fault condition) In this case, the buzzer keeps
sounding.
If the redundant cooling fan unit or EPS-R cage fails, the Fault lamp ( )
flashes to indicate the fault location.
Before asking for inspection and repair, check to see how the lamp flashes.
