Status Indicators
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. Appendix C displays the supervisor location on each switch.
The supervisor style depends on the switch model. These sections describe both supervisor styles.
Supervisor Indicators: 7508/7504
The 7508/7504 supervisor provides a serial console port, an Ethernet management port, and a USB port. Supervisor activity is reported by LEDs in the upper left quadrant. The Status Summary Screen in the center reports status for other components. Figure A-1 depicts the 7508/7504 Supervisor Module.

Supervisor Activity Status
The Status and Active LEDs report supervisor activity status. Table A-1 interprets the states of both LEDs.

Supervisor Indicators: 7508E / 7504E
The 7508E/7504E 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. Figure A-2 displays the 7508E/7504E Supervisor Module.

Supervisor Activity Status LEDs
The Status and Active LEDs are located on the left side of the Supervisor Module. Table A-3 interprets the states of these two LEDs.

Component Activity Status LEDs
LEDs located below the vents and left of the input ports display summary indicators for power supplies, fabric modules, fan modules, and line cards. Table A-4 interprets the states of these indicators. When error conditions are indicated, refer to LEDs on the specified modules to determine the condition’s source.

No modules are present or powered.
Green
All powered modules are operating normally.
Red
At least one module has failed.
Fan Modules
Amber
At least one fan is missing or has failed.
Green
All modules are operating normally.
Red
There are insufficient functional fans installed in the switch.
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. Figure A-3-left displays the status LED and Port LEDs on the left side of the DC-7548S-LC line card. Figure A-3-right displays the status LED and Port LEDs on the left side of the DCS-7500E-36Q-LC line card.
Figure A-3: line card Status LED
The line card Status LED is in the top left corner of the DC-7548S-LC line card. Table A-5 interprets the states of the Status LED.

Yellow
line card administratively shut down.
Red
Module has failed.
The line card provides LEDs for each port module socket:
• Figure A-3-left displays SFP module LEDs. Each LED corresponds to a module.
• Figure A-3-right displays QSFP module LEDs. 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 ports, each port is assigned to an LED within the set.
Table A-6 interprets the port LED states.

Fan and Fabric Status Indicators
Fan and Fabric Status LEDs are on fan modules (DCS-7508) or fan-fabric modules (DCS-7504, DCS-7508E, and DCS-7504E). Appendix D displays the position of these LEDs on the rear of each switch. Figure A-4 displays Fan Status and Fabric Status LEDs on the DCS-7508 and DCS-7504 switches.
