Ethernet Cards
The E100T-G 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 Ethernet capability enables network operators to provide multiple 10/100 Mbps
access drops for high-capacity customer LAN interconnects, Internet traffic, and cable modem traffic
aggregation. It enables the efficient transport and co-existence of traditional TDM traffic with
packet-switched data traffic.
Each E100T-G card supports standards-based, wire-speed, Layer 2 Ethernet switching between its
Ethernet interfaces. The IEEE 802.1Q tag logically isolates traffic (typically subscribers). IEEE 802.1Q
also supports multiple classes of service.
When making an STS-12c Ethernet circuit, the E-Series cards must be configured as single-card
Note
EtherSwitch.
5.3.1 Slot Compatibility
You can install the E100T-G card in Slots 1 to 6 and 12 to 17. Multiple E-Series Ethernet cards installed
in an ONS 15454 can act independently or as a single Ethernet switch. You can create logical SONET
ports by provisioning a number of 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.
5.3.2 E100T-G Card-Level Indicators
The E100T-G card faceplate has two card-level LED indicators, described in
Table 5-5
Card-Level Indicators
FAIL LED (Red)
ACT LED (Green)
SF LED
5.3.3 E100T-G Port-Level Indicators
The E100T-G card has 12 pairs of LEDs (one pair for each port) to indicate port conditions
You can find the status of the E100T-G card port using the LCD screen on the ONS 15454 fan-tray
assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and
severity of alarms for a given port or slot.

E100T-G Card-Level Indicators
Description
The red FAIL LED indicates that the card processor is not ready or that a
catastrophic software failure occurred on the E100T-G card. As part of the
boot sequence, the FAIL LED is turned on until the software deems the card
operational.
The green ACT LED provides the operational status of the E100T-G. If the
ACT LED is green it indicates that the E100T-G card is active and the
software is operational.
Not used.
