Ethernet Cards
Each E100T-12 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.
5.2.1 Slot Compatibility
You can install the E100T-12 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 synchronous transport signal (STS) channels to the packet switch entity within the
ONS 15454. Logical ports can be created with a bandwidth granularity of STS-1. The E100T-12 supports
STS-1, STS-3c, STS-6c, and STS-12c circuit sizes.
When making an STS-12c Ethernet circuit, the E-Series cards must be configured as single-card

EtherSwitch.
5.2.2 E100T-12 Card-Level Indicators
The E100T-12 card faceplate has two card-level LED indicators, described in

5.2.3 E100T-12 Port-Level Indicators
The E100T-12 card has 12 pairs of LEDs (one pair for each port) to indicate port conditions.
lists the port-level indicators. You can find the status of the E100T-12 card port using the LCD 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-12 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-12 card. As part of the
boot sequence, the FAIL LED is on until the software deems the card
operational.
The green ACT LED provides the operational status of the E100T-12. If the
ACT LED is green, it indicates that the E100T-12 card is active and the
software is operational.
Not used.
E100T-12 Port-Level Indicators
Description
The port is active (transmitting and receiving data).
The link is established.
The connection is inactive, or traffic is unidirectional.
