E100T-G Card
3.26.1 E100T-G Card-Level Indicators
The E100T-G card faceplate has three card-level LED indicators.
3.26.2 E100T-G Port-Level Indicators
The E100T-G card also has twelve pairs of LEDs (one pair for each port) to indicate port conditions. A
green LINK LED indicates a link is detected, ON indicates an active connection and OFF indicates an
inactive connection or unidirectional traffic.
You can find the status of the E100T-G card port using the LCD screen on the ONS 15454 SDH 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. Refer to Chapter 1, “Alarm Troubleshooting,” for a complete
description of the alarm messages.
Table 3-19 E100T-G Card-Level Indicators
Card-Level LEDs Description
Red FAIL LED The red FAIL LED indicates 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.
Table 3-20 E100T-G Port-Level Indicators
Port-Level Indicators Description
A (Yellow) The port is active. Data is being received and/or transmitted: By default, the
LED marked “A” indicates that the transmitter is active, but could also be
changed in this register to indicate link status, duplex status or an active
receiver.
L (Green) Link is established. Also, the LED marked “L” indicates by default that the
link for this port is up, but can also be programmed to indicate duplex status,
operating speed or collision.
