Chapter 14 Card Reference
Install TCC2 cards in Slots 7 and 11 for redundancy. If the active TCC2 fails, traffic switches to the
protect TCC2.
The TCC2 card has two built-in interface ports for accessing the system: an RJ-45 10BaseT LAN
interface and an EIA/TIA-232 ASCII interface for local craft access. It also has a 10BaseT LAN port for
user interfaces via the backplane.
Cisco does not support operation of the ONS 15454 with only one TCC2 card. For full functionality and
Note
to safeguard your system, always operate with two TCC2 cards.
When a second TCC2 card is inserted into a node, it synchronizes its software, its backup software, and
Note
its database with the active TCC2. If the software version of the new TCC2 does not match the version
on the active TCC2, the newly inserted TCC2 copies from the active TCC2, taking about 15 to 20
minutes to complete. If the backup software version on the new TCC2 does not match the version on the
active TCC2, the newly inserted TCC2 copies the backup software from the active TCC2 again, taking
about 15 to 20 minutes. Copying the database from the active TCC2 takes about 3 minutes. Depending
on the software version and backup version the new TCC2 started with, the entire process can take
between 3 and 40 minutes.

Definition
This LED is on during reset. The FAIL LED flashes during the boot and
write process. Replace the card if the FAIL LED persists.
Indicates the TCC2 is active (green) or in standby (yellow) mode. The
ACT/STBY LED also provides the timing reference and shelf control. When
the active TCC2 is writing to its database or to the standby TCC2 database,
the card LEDs blink. To avoid memory corruption, do not remove the TCC2
when the active or standby LED is blinking.

Indicates major alarms in the network at the local terminal.
Indicates minor alarms in the network at the local terminal.
Provides first-level alarm isolation. The remote (REM) LED turns red when
an alarm is present in one or more of the remote terminals.
