Status Indicators
A.1 Supervisor Module
While the front panel of each switch can house two supervisors, switch operations require only one. Supervisors display switch component status and contain Ethernet management and console ports.
A.1.1 Supervisor Indicators: 7500E-SUP/7500-SUP2
The supervisor provides one serial console port, two Ethernet management ports, two USB ports, and one clock input port. Supervisor activity is reported by LEDs in the upper left corner. Four LEDs located left of the input ports report status of other switch components.

Supervisor Activity Status LEDs
The Status and Active LEDs are located on the left side of the Supervisor Module. Table A-1 interprets the states of these two LEDs.

Status
Off
No power, failed, or improperly inserted.
Green
Operating normally.
Red
Supervisor failed.
Active
Off
Not active.
Green
Active and controlling the switch.
Component Activity Status LEDs
LEDs located below the vents and left of the input ports display summary indicators for power supplies, fabric modules, fans, and line cards. Table A-2 interprets the states of these indicators. When error conditions are indicated, refer to LEDs on the specified modules to determine the condition’s source.

A.2 Line Card Module Indicators
Each line card module provides one status LED plus LEDs for each port on the card. The figures in Appendix E indicate the location of the LEDs on each line card.

Off
Line card not inserted.
Green
Line card operating normally.
Yellow
Line card administratively shut down.
Red
Line card has failed.
The line card provides LEDs for each port module socket:
Each LED corresponds to a module.
A set of four LEDs correspond to each module. When the module is programmed as a 40G port, the first LED in the set reports status. When the module is programmed as four 10G or 100G ports, each port is assigned to an LED within the set.
Table A-4 interprets the port LED states.

A.3 Fabric Status Indicators
Fabric Status LEDs are on fan-fabric modules. Appendix D displays the position of these LEDs on the rear of each switch. Figure A-5 displays fan status and fabric status LEDs on the switch.
Note Gen 1 Fabric modules are not supported.
