Troubleshooting Using the Alarm Card

The alarm card is installed in the rightmost slot in the upper card cage. The slot is labeled
Alarm card and is slightly narrower than the rest of the slots in the upper card cage. In
addition, the alarm card slot backplane connector is different from the rest of the backplane
connectors in the upper card cage.
The alarm card has three primary functions:
•
Provides a visual display of the three stages of system alarm (critical, major, and minor)
detected by the system's environmental monitor. Three pairs of LEDs (two pair of LEDs
are red, one pair of LEDs is amber) on the alarm card faceplate are driven by the
environmental monitor software in the system.
When the environmental software detects an abnormal condition (such as
overtemperature or overvoltage), the software determines the severity of the condition
and sets the appropriate pair of alarm card LEDs. The alarm card LEDs are paired for
redundancy.
