Table D-2 lists the LED descriptions for the RJ-45 Ethernet port LEDs.
Ethernet and Fibre Channel LEDs
There are activity LED’s per-port on the Cisco Nexus 6004 faceplate. The LEMs and GEMs have the
same port level indicators as the fixed ports. Since 40G ports are comprised of 4x 10G ports, they wi
have 4x LEDs, one-LED-per-10G-port. Each LED represents the status of the 10G link within the 40G
bundle, and follows the behavior in the table below. Table D-3 describes the behavior of the port LEDs.

ALT_GREEN_AMBER LED alternates between Amber
and Green for 2 seconds (at 0.5
second intervals) when it observes
errors on the link. This is the error
