Chapter 4 Card Reference
E100T-G Card
You can install the E100T-G card in any multispeed slot. Multiple 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.
Note When making an STS-12c Ethernet circuit, the E100 or E1000 cards must be configured as
single-card EtherSwitch.
4.30.1 E100T-G Card-Level Indicators
The E100T-G card faceplate has two card-level LED indicators.
4.30.2 E100T-G Port-Level Indicators
The E100T-G card also 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. See Chapter 1, “Alarm Troubleshooting” for a complete description of
the alarm messages.

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 E100T-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 E100T-G. When the
ACT LED is green it indicates that the E100T-G card is active and the
software is operational.
