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 major alarm is sent to the control module, and the appropriate LED color on
the GX2-PSAC10D-R illuminates.
Table 3-1 lists the possible LED colors and the probable 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-PSAC10D-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-PSAC10D-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-PSAC10D-R is reported to the GX2-CM100B and is accessible through the GX2-SDU or the
Ethernet port on the front panel. Using the GX2-SDU, or a network management system, you can
identify the cause of a fault in the GX2-PSAC10D-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
LEDs give the same indication as identified in Table 3-1. If the
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.
