LED Indicators
TCC+ and TCC2 Cards
The TCC+ and TCC2 (TCC) cards have the following LED indicators on the faceplates:
Card-Level Indicators:
Red FAIL LED - This LED is lit during reset. The FAIL LED flashes during the boot and
write process. Replace the card if the FAIL LED persists.
ACT/STBY LED - The ACT/STBY (Active/Standby) LED indicates the TCC is in active
mode when the LED is green, and in standby mode when it is yellow. The ACT/STBY
LED also provides the timing reference and shelf control. When the active TCC is writing
to its database to the standby TCC database, the card LEDs blink. To avoid memory
corruption, do not remove the TCC when the active or standby LED is blinking.
