Status Indicators
Supervisor Module Status Indicators
The supervisor displays switch component status and contains Ethernet management and console ports. The supervisor location is on the Front Panels of the switch.
The supervisor provides one serial console port, one Ethernet management port, 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 supervisor module status LEDs.
1 | System Status LED | 3 | Power Supply Status LED |
2 | Fan Status LED | 4 | Switch Card Status LED |
Supervisor Status LEDs
The following table interprets the states of the LED indicators on the supervisor module. When error conditions are indicated, refer to LEDs on the specified components to determine the condition’s source.
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 | There are insufficient functional fans installed in the switch. |
(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.
Linecard Module Indicators
Each linecard module provides one status LED plus LEDs for each port on the card.
The following figure displays the status LED and port LEDs on the DCS-7388-16CD linecard. Arrows indicate the port status being displayed by the corresponding port status LED.
1 | Linecard | 3 | Linecard Status LED | 5 | Port Status LEDs |
2 | Linecard Ejector (Release) Handle | 4 | Linecard Ports |
The Linecard Status LED is in the center of the DCS-7388-16CD. The following tables interpret the states of the Status LED and the port LED.
LED State | Status |
---|---|
Off | Linecard not inserted. |
Green | Linecard operating normally. |
Yellow (amber/orange) | Linecard administratively shut down. |
Red | Linecard has failed. |
LED State | Status |
---|---|
Off | Port link is down. |
Green | Port link is up. |
Yellow (amber/orange) | Port is disabled in software. |
LED State | Status |
---|---|
Off | Port link is down for enabled interfaces. |
Green | Port link is up for enabled interfaces and all links are good. |
Yellow (amber/orange) | Port is disabled in software for all interfaces or a link is bad. |
Fan Module Status Indicators
The fan modules are inserted into the switch card module. Each switch contains one switch card and five fan modules accessible from the Rear Panels of the switch.
1 | Fan Airflow Direction Indicator Bezel Color | 3 | Fan Status LED |
2 | Fan Release Handle |
The following table interprets the states of the Fan Status LED.
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 power supply modules for all switches are accessible from the Rear Panels of the switch.
The following figure displays a power supply module.
The power supply handle indicates the power supply airflow direction. Verify the airflow direction of all fan and power modules. All modules should have the same color handles.
1 | Power Supply Status LED |
The following table interprets the states of the Power Supply Status LED.
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. |
