If a single component or a set of components on the switching module fails, this failure will not disable another switching module if that is the only failure in the system.

For the detection of most component failures, each switching module has a hardware watchdog timer that resets the card if is not serviced periodically.

LED

 

Status

Description

 

 

 

 

Status

 

Green

All diagnostics pass. The module is operational (normal

 

 

 

initialization sequence).

 

 

 

 

 

 

Orange

One of the following occurs or occurred:

 

 

 

The module is booting or running diagnostics (normal

 

 

 

initialization sequence).

 

 

 

The inlet air temperature of the system exceeded the

 

 

 

maximum system operating temperature limit (a minor

 

 

 

environmental warning). To assure maximum product life,

 

 

 

you should immediately correct the environmental

 

 

 

temperature and restore the system to normal operation.

 

 

 

 

 

 

Red

One of the following occurred:

 

 

 

The diagnostic test failed. The module is not operational

 

 

 

because a fault occurred during the initialization sequence.

 

 

 

The inlet air temperature of the system exceeded the safe

 

 

 

operating temperature limits of the card (a major

 

 

 

environmental warning). The card shut down to prevent

 

 

 

permanent damage.

 

 

 

 

Speed

 

On

2-Gbps mode.

 

 

 

 

 

 

Off

1-Gbps mode.

 

 

 

 

Link
