OR
Card is not receiving power.
OR
Card is in Standby Mode.
Ethernet Line Card Standby LED States
The Standby LEDs on the Ethernet line cards indicate that software is loaded on the cards, but are serving as
redundant components.
The line cards will remain in a ready mode until their corresponding packet processing card is made active
via configuration. While in ready mode, the Active LED should be off. After the packet processing card is
made active, the line card installed in the upper-rear chassis slot behind the packet processing card will also
be made active. The line card (except for the full-height XGLC) installed in the lower-rear chassis slot behind
the packet processing card will also enter the standby mode.
The possible states for this LED are described below. If the LED is not green, use the troubleshooting
information in the table to diagnose the problem.

Color
Description
Green
Card is in redundant mode.
Troubleshooting
None needed for line cards installed in slots 17 through 23 and 26 through 32 after
configuration.
If green for half-height line cards in slots 33 through 39 and 42 through 48, verify
that the corresponding line card installed in the upper-rear chassis slot is installed
properly according to the instructions in this document.
For example, if this LED is green for a line card in slot 33, verify that the line card
in slot 17 is installed properly.
This is normal prior to configuration. Neither the Active or the Standby LED on the
card is on.
Verify that the Run/Fail LED is green. If so, the card is receiving power and POST
test results are positive. If it is off, the card is not receiving power.
Check the state of the Standby LED. If it is green, the card is in standby mode. This
is normal operation for the initial power-up. If needed, refer to the Configuring Packet
Processing and Line Card Availability section of System Settings for information on
making the card active.
Troubleshooting
None needed for half-height line cards installed in slots 33 through 39 and 42 through
48 after configuration.
If green for line cards installed in slots 17 through 23 and 26 through 32, refer to
Monitoring the System for information on determining the status of the line card and
system software processes.
