FAIL LED (Red)

The red FAIL LED indicates that the card processor is not ready or that a 
catastrophic software failure occurred on the card. As part of the boot 
sequence, the FAIL LED turns on and flashes until the software deems the 
card operational.

The ACT/STBY LED is green if the card is the active CTX2500 card. It is 
amber if the card is the standby card.

SYNC LED 
(Green/Amber)

The SYNC LED is green if the CTX2500 card detects both a primary and 
secondary clock reference. It is amber if the card detects only a single clock 
reference.
