1.4.5.2 LED Indicators
The OC-12c/STM-4c 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-12c/STM-4c Network Module.
1.4.6 Gigabit Ethernet Network Module
The Gigabit Ethernet Network Module provides two ports of Gigabit Ethernet (IEEE 802.3z/802.3ab) for
connectivity at 1 Gbps. The Gigabit Ethernet Network Module runs at slightly less than full line rate under
certain operating conditions. This dual port module plugs into the backplane, which connects to the switch
fabric. The Gigabit Ethernet Network Modules use GBICs for the physical interface. The GBICs are hot
swappable and are available in 850nm multimode fiber, 1310nm single-mode fiber, and HSSDC or DB9 copper
versions.
See Section 2.3.2 for more information about Gigabit Ethernet Network Module GBIC options.
