Troubleshooting Tips (continued)
Action
Check if the FAULT LED is illuminated (yellow) and check the position of
1.
the DC power switch. The power switch may be in Standby (0) position, thus
the POWER LED is not illuminated.
2. Switch the DC power switch to ON (|) position and check if the POWER LED
illuminates.
3. If the DC power switch is turned ON, and the POWER LED still does not
illuminate (green), the POWER LED may be defective. If the system is
receiving DC power (the internal fans are working) and the second DC PEM
module is not supplying power to the chassis, then the POWER LED may be
defective. See the
Request" section on page
If the V1 POWER or the V2 POWER LEDs on the AC PEMs do not
•
illuminate, verify the input voltage of the source.
If the FAULT LED does not illuminate (yellow) when the AC power switch
•
is in Standby (0) position, it indicates that the FAULT LED could be
malfunctioning. The POWER LED will be off.
• If AC power switch is turned ON, and POWER LED does not illuminate
(green), the POWER LED may be defective. See the
Documentation and Submitting a Service Request" section on page
If the system is receiving power (the internal fans are working) and the
•
second AC PEM module is not supplying power to the chassis, the POWER
LED may be defective. See the
Service Request" section on page
