RED ALM or Alarm LED

The RED ALM or Alarm LED is on the top-left most corner of the LED Panel next to other important system LEDs (PWR, CPU, MSTR), as specified in Figure 19. The presence of this RED ALM LED is primarily for on-site service technicians or dispatches. It alerts technicians of major failures that require a physical replacement or removal of equipment. Most major G700 components controlled or monitored by the motherboard can be a cause of illumination. This includes the Avaya VoIP Media Module, but not other Media Modules.

Note: The RED ALM LED lights for motherboard problems only. Check for a RED ALM LED for problematic G700s and also check all of the Media Module LEDs for any Media Module specific RED ALM LEDs.

Note: If the RED ALM LED is lit on a non-VoIP Media Module, check the G700 alarm screens and the Avaya Communication Manager alarm screens to determine where the fault lies.

The RED ALM LED indicates the health of the G700 by lighting under two distinct circumstances:

• G700 hardware failure
• Impaired functions of the Layer 2 Switching Processor, Media Gateway Processor, or VoIP engine
• Power supply voltage out of bounds
• Unit overheating
• The G700 cannot communicate to any server

The following are a few examples:

• The RED ALM LED is lighted when two or more fans have failed.

Various warnings, alarms, and a graceful shutdown are performed based on the fan and thermal sensor conditions.

• The RED ALM LED is lit from the time power is applied until diagnostics end.
• The RED ALM LED turns "OFF" when:
1. Physical conditions such as temperature are rectified and return to normal or acceptable operating ranges.
2. The alarm is cleared manually.
