Status Indicators

This section discusses the following topics:

Supervisor Module

The supervisor displays the switch component status and contains Ethernet management and console ports. The Front Panels display the supervisor's location on the switches.

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. The following figure shows the LED status of the supervisor module.

Supervisor Status LEDs

The following table interprets the states of the LED indicators on the supervisor module. When indicating error conditions, refer to LEDs on the specified components to determine the condition’s source.

 

Table 1. Supervisor LED States (1)
LED Name LED State Module State
Power Supply Green All powered modules are operating normally.
Red At least one module has failed.
System Green All linecards are operating normally.
Red At least one linecard has failed.
Switch Card Green Module is operating normally.
Red Module has failed.
Fan Amber At least one fan is missing or has failed.
Green All modules are operating normally.
Red Additional functional fans need to be installed on the switch.
1 If all Status LEDs are OFF, check the following: power feeds are live, power supplies are installed, the Switchcard is properly seated, and The supervisor is properly seated. The system will only power up if all four conditions are valid.

 

line Card Module Indicators

Each line card module provides one status LED plus LEDs for each port on the card. The figures in linecards indicate the location of the LEDs on each line card. The following figure displays the status LED and Port LEDs on the DCS-7368-16C line card. Arrows indicate the port status being displayed by the corresponding port status LED.

LED State Status
Off line card not inserted.
Green line card operating normally.
Amber line card administratively shut down.
Red line card has failed.

 

The following tableinterprets the port LED states.

LED State Status
Off The port link is down.
Green Port link is up.
Yellow Port is disabled in the software.

 

Fan Module Status Indicators

The fan modules are inserted into the switch card module. Each switch contains one switch card and five fan modules. Rear Panels displays the rear panel of the switch. The following figure displays the fan module indicator. 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.

The fan installation Indicator is green when the fan module is properly installed or red when the module is not fully installed. The following table interprets the states of the Fan Status LED.

 

Table 4. Fan Status LED States
LED State Status
Off The module is inserted but not receiving power – it may not be properly seated.
Green The module is operating normally.
Red The module has failed.

 

Power Supply Status Indicators

Power Supply LEDs are on power supply modules. The rear panel contains power supply modules for all switches. The Rear Panels display the position of these LEDs on each switch.

The following figure displays a power supply module.

The power supply handle indicates the power supply fan direction. Verify that the airflow direction of all modules has the same color handles.

The following table interprets the state of the Power Supply Status LED.

 

Table 5. Power Supply Status
LED Status
Green Power Supply module operating normally.
Off No AC power to the module.
Red Module has faulted.
Blinking Green PSU has AC power but hasn't been enabled by the system - indicates that either the power supply or the Switch Module isn't fully inserted.
