E1000-2-G Card
The E1000-2-G Gigabit Ethernet card provides high-throughput, low-latency packet switching of
Ethernet traffic across a SONET network while providing a greater degree of reliability through SONET
“self-healing” protection services. This enables network operators to provide multiple 1000 Mbps access
drops for high-capacity customer LAN interconnects. It enables efficient transport and co-existence of
traditional TDM traffic with packet-switched data traffic.
Each E1000-2-G card supports standards-based, layer 2 Ethernet switching between its Ethernet
interfaces and SONET interfaces on the ONS 15454. The 802.1Q VLAN tag logically isolates traffic
(typically subscribers). The E1000-2-G supports two 802.1Q.
You can install the E1000-2-G card into any multispeed slot. Multiple Ethernet cards installed in an ONS
15454 can act together as a single switching entity or as an independent single switch supporting a
variety of SONET port configurations.
You can create logical SONET ports by provisioning STS channels to the packet switch entity within the
ONS 15454. Logical ports can be created with a bandwidth granularity of STS-1. The ONS 15454
supports STS-1, STS-3c, STS-6c, or STS-12c circuit sizes.
Note When making an STS-12c Ethernet circuit, the E100 or E1000 cards must be configured as
single-card EtherSwitch.
4.31.1 E1000-2-G Card-Level Indicators
The E1000-2-G card faceplate has two card-level LED indicators.
4.31.2 E1000-2-G Port-Level Indicators
The E1000-2-G card also has one bicolor LED per port. When the green LINK LED is on, carrier is
detected, meaning an active network cable is installed. When the green LINK LED is off, an active
network cable is not plugged into the port, or the card is carrying unidirectional traffic. The amber port
ACT LED flashes at a rate proportional to the level of traffic being received and transmitted over the
port.

Card-Level Indicators Description
Red FAIL LED
The red FAIL LED indicates that the card’s processor is not ready or
catastrophic software failure occurred on the E1000-2-G card. As part of the
boot sequence, the FAIL LED is turned on until the software deems the card
operational.
Green ACT LED
A green ACT LED provides the operational status of the E1000-2-G. When
the ACT LED is green it indicates that the E1000-2-G card is active and the
software is operational.
SF LED
Not used
