System and port status LED indicators are located on the front of the switches.
Front panel LEDs are located on the right side of the chassis and display system, fan, and power supply status. Front Panel displays the front panels of all switches covered by this guide.
Figure 1 displays the front panel LEDs.
|1||System status LED||3||PSU 1 status LED|
|2||Fan status LED||4||PSU 2 status LED|
|LED Name||LED State||Device Status|
|System Status||Blinking Green||System powering up.|
|Green||All power supplies and fans are operating normally.|
|Blue||The locator function is active.|
|Red||A power supply or fan is missing or in a failed state.|
|Fan Status||Green||All fans are operating normally.|
|Red||One or more fans are not inserted or have failed.|
|Power Supply Status||Off||Power supply is not inserted or is not powered.|
|Green||Power supply operating normally.|
|Red||Power supply has failed.|
Port LEDs, located in the vicinity of their corresponding ports, provide link and operational status.The following figure displays the Port LED location on a representative switch.
|1||Port 4 status LED||3||Port 2 status LED|
|2||Port 3 status LED||4||Port 1 status LED|
Table 2 provides status conditions that correspond to port LED states. Port LED behavior for QSFP+ and SFP+ ports is consistent.
|Off||Port link is down.|
|Green||Port link is up.|
|Yellow||Port is software disabled.|
|Flashing Yellow||Port failed diagnostics.|
Rear Status Indicators
The fan module contains an LED that reports the module status. Fan Status LEDs are on the fan modules and are visible through the cover.
The fan module orientation determines the direction of air flowing through the switch. The fan module, when inserted, covers one of the two airflow labels with the visible label indicating the current airflow direction.
The switch shuts down when the fan module is removed for more than one minute.
|1||Airflow direction indicator label||3||Fan module handle and release||5||Fan status LED|
|2||Fan status LED||4||Airflow direction indicator label||6||Fan module handle and release|
To change the airflow direction, change the fan module orientation:
- While squeezing the fan module handle, pull the fan module out of the switch.
- Rotate the fan module 180°.
- Insert the fan module back into the switch.
The following table provides status conditions that correspond to fan status LED states.
|Off||The fan module is inserted but not receiving power – it may not be properly seated.|
|Green||The fan is operating normally.|
|Red||The fan has failed.|
