4.2.3 System Faults
4.2.4 Power Supply/Cooling Faults
Symptom Cause Action
1. The System Fault LED
turns amber on front panel.
The ESI processor has
detected an internal fault
(for example, failure of an
internal communications
path) 1. Check for other amber LED
indications on the power cooling
modules. If there is a PSU error present
there may be a communications problem
with that power cooling module.
Remove and then re-fit the module. If
the problem persists, then replace the
module.
2. Check for other amber LED
indications on the drive modules. If none
are evident, then there may either be an
ESI processor problem or a backplane
problem.
Symptom Cause Action
1. System Fault LED is
amber on front panel.
2. An amber LED on one or
more power cooling
modules.
1. Any power fault
2. A fan failure
3. A thermal condition
which could cause PSU
overheating
1. Ensure that the power On/Off switch
on rear of power cooling module is
turned ON.
2. Ensure that the AC main connection to
the power cooling module is live.
3 . Disconnect the power cooling module
from the main power, remove the
module from the system, and re-install
the module. If the problem persists,
replace the power cooling module.
4 . Reduce the ambient temperature.
