7388X5 Series - 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.

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.

Table 1. Supervisor LED States
LED Name	LED State	Module State
Power Supply	Green	All powered modules are operating normally.
Power Supply	Red	At least one module has failed.
System	Green	All linecards are operating normally.
System	Red	At least one linecard has failed.
Switch Card	Green	Module is operating normally.
Switch Card	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.

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.

Table 2. Linecard Status LED States
LED State	Status
Off	Linecard not inserted.
Green	Linecard operating normally.
Yellow (amber/orange)	Linecard administratively shut down.
Red	Linecard has failed.

Table 3. Linecard Port LED States (SFP, QSFP)
LED State	Status
Off	Port link is down.
Green	Port link is up.
Yellow (amber/orange)	Port is disabled in software.

Table 4. Linecard Port LED States (OSFP, QSFP-DD)
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.

The fan module indicator is displayed in the following figure. 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.

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.

Table 5. Fan and switch card 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 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.

Table 6. 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.
