Possible causes
Cause 1: AC power input to the power module is incorrect
Cause 2: The power module is faulty or in protection mode
Cause 3: The CPU is in over-temperature protection mode
Procedure
Cause 1: AC input to the power supply module is incorrect
Note: There are two power modules in each SIEM 9700 Series appliance, each
with an AC main power socket and an on/alarm indicator. These instructions
assume that each power module will be tested.
1.
Check whether the power/sleep indicator on the control panel on the front
of the SIEM 9700 Series appliance and the on/alarm LED near each AC
power socket on the rear panel of the SIEM 9700 Series appliance are off.
2.
If the two LEDs are off, remove and reinsert the AC power plug.
•
If the power/alarm LED flashes green, the abnormal power-off
was caused by a loose plug connection.
•
If the power and on/alarm LEDs are still off, it is possible that
AC power to the equipment room is faulty. In this case, contact
the customer for resolution.
•
If the equipment room power is normal, the power module is
faulty.
3.
If the power/alarm indicator is amber, check the other power supply for
further analyses.
4.
If both the LEDs are amber, contact technical support.
Cause 2: The power module is faulty or in protected mode
1.
Check whether the power status LED and the alarm LED are amber.
2.
If both the LEDs are amber, contact technical support.
3.
If only one LED is amber, check other components for further analyses.
