Hardware Overview Introduction
The ATM Multi-rate line card uses the following LEDs.
ATM OC-12c Line Card
The ATM OC-12c line card supplies one logical connection, through two physical ports (Link 1 and Link 2). Link 1 is
the working (primary) port and Link 2 is the protecting (backup) port.
Note
Do not try to use Link 2 port for another connection different from Link 1. Link 2
and Link 1 act as redundant ports for APS and are essentially one logical port.
