Fault Reporting

Each output voltage and the internal voltage of the supplies is monitored. The temperature of
the incoming air, the heat sink, and fan operation are monitored as well. In the event of a fan
failure, a major alarm is sent to the GX2-CM100B control module and the local LED glows red.
The monitored signals are all compared to their appropriate internal specification. When a
deviation occurs, either a minor or a major alarm is sent to the control module and the
appropriate LED color on the GX2-PSDC10D-R illuminates.
Table 3-1 lists the possible LED colors and the probable fault indication:
Table 3-1
LED fault indication
LED color Fault Indication
Green Power is applied and all measured parameters are within tolerance.
Yellow A minor alarm is detected; however, the GX2-PSDC10D-R is not rendered
inoperative.
Red A major alarm is detected and immediate intervention is required.
Not lit If the LED is not lit, verify that system power is available.
The GX2-PSDC10D-R also includes non-volatile memory to store module identity information
that includes model number, serial number, and manufacturing date code. To access this
information, the GX2-CM100B Control Module must be installed in the GX2-HSG*. Data from
the GX2-PSDC10D-R is reported to the GX2-CM100B and is accessible through the GX2-SDU or
the Ethernet ports on the front and rear panels. Using the GX2-SDU, or an element
management system, you can identify the cause of a fault in the GX2-PSDC10D-R. Refer to
Appendix B, Menus, for information regarding the SDU menu structure.
The GX2-CM100B front panel also contains two tri-colored LEDs identified as
These LEDs give the same indication as identified in Table 3-1. If the
then a power supply is not installed or the installed power supply is not functional.
If one power supply fails in a redundant application, you can still access the failed power supply
through the SDU or EMS. This is possible as the microprocessor on each power supply is
powered from the backplane voltage rather than internally from the power supply.
