This document describes how to interpret the link light status on an Ethernet card on a Cisco ONS 15454.
There are no specific requirements for this document.

Ethernet cards include:
The E100T and E1000-2 cards have been discontinued, but are included here because they will continue to be supported until March 28, 2007. These cards have been replaced with equivalent boards. The E100T-G is the functional equivalent of the discontinued E100T-12, and the E1000-2-G is the functional equivalent of the discontinued E1000-2. Refer to End of Life Announcement for E100T and E1000-2 cards for Cisco ONS 15454 for more information.
The 15454 uses E100T and E100T-G cards for Ethernet (10 Mbps) and Fast Ethernet (100 Mbps) and the E1000-2 and E1000-2-G cards for Gigabit Ethernet (1000 Mbps). The E100T and E100T-G enable network operators to provide multiple 10/100 Mbps and the E1000-2 and E1000-2-G enable network operators to provide multiple 1000 Mbps access drops for high-capacity customer LAN interconnections.
Each port has one LED, which can turn Amber (yellow-orange) or Green. This table shows the meaning of all possible LED states associated with the specific Ethernet port:
|Amber||Transmitting and Receiving.|
|Flashing Amber||Flashes proportionally to traffic.|
|Flashing Green||Transmitting only or Receiving only.|
|Solid Green||Idle and Link Integrity is good.|
|OFF||Inactive Connection or Unidirectional Traffic.|
