Network-Level Indicators - Cisco 15454-TCC - Network Processor Card Operation Manual

TCC-I Timing Communication and Control Card Description
Install TCC-I cards in Slots 7 and 11 for redundancy. If the active TCC-I fails, traffic switches to the
protect TCC-I. All TCC-I protection switches conform to protection switching standards when the BER
counts are not in excess of 1*10
The TCC-I uses a 10Base-T LAN port for user interfaces, being led via the back plane to the port
accessible on the front panel of the MIC-C/T/P unit.
Note Cisco does not support operating the ONS 15454 SDH with only one TCC-I card. For full functionality
and to safeguard your system, always operate in a redundant configuration.
CTC software does not monitor for the presence or absence of FMECs unless the TCC-I(s) card has
Note
reached the active/standby state. During transitional states such as power-up or TCC-I reset CTC ignores
the FMEC inventory displayed in node view.
When a second TCC-I card is inserted into the shelf, it will synchronize its software, its backup software,
Note
and its database with the active TCC-I.
If its software version does not match the version on the active TCC-I, the newly inserted TCC-I will
copy from the active TCC-I. This copying will take about 15 to 20 minutes.
If its backup software version does not match the version on the active TCC-I, the newly inserted TCC-I
will copy the backup software from the active TCC-I. This copying, again, will take about 15 to 20
minutes.
Copying the database from the active TCC-I will take about 3 minutes.
So, depending on the software existing in the new TCC-I, booting it up will take between 3 and about
40 minutes.
TCC-I Card-Level Indicators
The TCC-I faceplate has eight LEDs. The first two LEDs are card-level indicators.

Definition
This LED is lit during Reset. The FAIL LED flashes during the boot and
write process. Replace the unit if the FAIL LED persists.
The ACT/STBY (Active/Standby) LED indicates the TCC-I is active
(green) or in standby (yellow). The ACT/STBY LED also provides the
timing reference and shelf control. When the TCC-I is writing to the Active
or Standby TCC-I, its Active or Standby LED will blink. Do not pull the
TCC-I out during this time to avoid memory corruption.
