Troubleshooting Using the Alarm Display
If you experience critical, major, or minor alarms you can use the alarm display
to troubleshoot those conditions. The following connectors and indicators are on
the front panel of the alarm display (
Figure 4-10 ):
• Cable connections for the two alarm cards (labeled Alarm A and Alarm B).
• Critical (red), Major (red), and Minor (yellow) indicators that identify system
level alarm conditions detected by the system through the MBus. These
indicators are normally off.
• Alarm card indicators (labeled MBus) that correspond to alarm cards
connected to Alarm A and Alarm B:
1. ENABLED (green)—Alarm card is operational and functioning properly.
2. FAIL (yellow)—Alarm card in that slot is faulty.
• Two status LEDs that correspond to each of the CFC and SFC card slots in
the switch fabric and alarm card cage:
– ENABLED (green)
On—The card installed in that slot is operational and functioning
properly.
Off—Either the slot is empty or the card installed in that slot is faulty.
– FAIL (yellow)—The card in that slot is faulty.
