Table D-1 table describes the status of the two power supply LEDs

Conditions Indicated by the Power Supply LEDs

You can determine the power supply conditions by combining the LED states of the OK and FAIL LEDs (see Table D-1).

(Amber)

No AC or DC power to all power supplies.

Off

Off

Power supply failure, including over voltage, over current, over temperature, and fan failure.

Off

On

Power supply warning events where the power supply continues to operate. These events include high temperature, high power, and slow fan.

Off

Blinking

AC present, 3.3 voltage standby (VSB) on, and the power supply unit is off.

For a DC power supply, it indicates that DC power is present.

Activity


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.

CRC errors

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

behavior on the Cat3K line of

products.
