Status Indicators
A.1 Supervisor Module
The supervisor displays switch component status and contains Ethernet management and console ports. Appendix C displays the supervisor location on the switch.
The supervisor provides one serial console port, two Ethernet management ports (one RJ-45, one optical), and one USB port. Four LEDs on the top edge report system status, fan status, power status, and switch module status. Figure A-1 shows the supervisor module status LEDs.

(1): If all Status LEDs are OFF, check the following: power feeds are live, power supplies are installed, Switch Card is properly seated, and Supervisor is properly seated. The system will not power up unless all four of these conditions are valid.
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. Figure A-2 displays the status LED and Port LEDs on the DCS-7368-16C-LC line card. Arrows indicate the port status being displayed by the corresponding port status LED.

A.3 Fan Module Status Indicators
The fan modules are inserted into the switch card module. Each switch contains one switch card and five fan modules. Appendix D displays the rear panel of the switch covered by this guide.The fan module indicator is displayed in Figure A-3. The fan handle color indicates the airflow direction. All fan modules must have the same color handle.
Note The orientation of the fan module as inserted in the switch may be different from the one shown.

A.4 Power Supply Status Indicators
Power Supply LEDs are on power supply modules. The rear panel contains power supply modules for all switches. Appendix D (rear panels) displays the position of these LEDs on each switch.
Figure A-4 display a power supply module.
The power supply handle indicates the power supply fan direction. Verify the airflow direction of all modules have the same color handles.
