firmware is executing ADMIN code.

 

 

 

 

FAIL

Red

• Steady Red with Active and Standby LEDs off indicates either

 

 

 

the card is in the Reset condition, the card has failed, or the card

 

 

 

set is not complete (no line module).

 

 

 

• Steady Red with Active LED on indicates the card was active

 

 

 

prior to failing

 

 

 

• Steady Red with Standby LED on indicates the card was

 

 

 

standby prior to failing.

 

 

 

• Both standby and red LED alight indicates self-test failure.
