1.4.4.2 LED Indicators
The OC-48c/STM-16c Network Module has a Link/Active LED as well as an Isolation LED on the front panel.
The following table describes how to interpret the LEDs on the front of the OC-48c/STM-16c Network Module.
1.4.5 OC-12c/STM-4c Network Module
The OC-12c/STM-4c Network Module provides two ports of OC-12c/STM-4c Packet over SONET/SDH for
network connectivity at 622 Mbps. This dual port module plugs into the backplane, which connects to the switch
fabric. The OC-12c/STM-4c Network Module has a built in optical transceiver with an LC optical interface, and
accepts a single mode fiber cable with an LC type connector. Note that for both ports, scrambling is always on.
Also, the PPP links must be operational for the port to establish communications. The PPP control link will not
have keepalive on, but will respond to keepalive messages from the far end.
