2.3.2 TCC2P Card-Level Indicators
Note When a second TCC2P card is inserted into a node, it synchronizes its software, its backup software, and
its database with the active TCC2P. If the software version of the new TCC2P does not match the version
on the active TCC2P, the newly inserted TCC2P copies from the active TCC2P, taking about 15 to
20 minutes to complete. If the backup software version on the new TCC2P does not match the version
on the active TCC2P, the newly inserted TCC2P copies the backup software from the active TCC2P
again, taking about 15 to 20 minutes. Copying the database from the active TCC2P takes about 3
minutes. Depending on the software version and backup version the new TCC2P started with, the entire
process can take between 3 and 40 minutes.
2.3.2 TCC2P Card-Level Indicators
The TCC2P faceplate has ten LEDs. Table 2 -12 describes the two card-level LEDs on the TCC2P
faceplate.
2.3.3 Network-Level Indicators
Table 2-13 describes the six network-level LEDs on the TCC2P faceplate.
Table 2-12 TCC2P Card-Level Indicators
Card-Level LEDs Definition
Red FAIL LED This LED is on during reset. The FAIL LED flashes during the boot and
write process. Replace the card if the FAIL LED persists.
ACT/STBY LED
Green (Active)
Amber (Standby)
Indicates the TCC2P is active (green) or in standby (amber) mode. The
ACT/STBY LED also provides the timing reference and shelf control. When
the active TCC2P is writing to its database or to the standby TCC2P
database, the card LEDs blink. To avoid memory corruption, do not remove
the TCC2P when the active or standby LED is blinking.
Table 2-13 TCC2P Network-Level Indicators
System-Level LEDs Definition
Red CRIT LED Indicates Critical alarms in the network at the local terminal.
Red MAJ LED Indicates Major alarms in the network at the local terminal.
Amber MIN LED Indicates Minor alarms in the network at the local terminal.
Red REM LED Provides first-level alarm isolation. The remote (REM) LED turns red when
an alarm is present in one or more of the remote terminals.
Green SYNC LED Indicates that node timing is synchronized to an external reference.
Green ACO LED After pressing the ACO button, the ACO LED turns green. The ACO button
opens the audible alarm closure on the backplane. ACO is stopped if a new
alarm occurs. After the originating alarm is cleared, the ACO LED and
audible alarm control are reset.
