Problem Description
Customer feedback, an S6520X-SI port indicator in the server room has been showing yellow constant light, and the opposite end is connected to some APs, VOIPs and end users. The customer wants to confirm whether the yellow indicator light means that the device is faulty.
Solution
There are two port modes: speed mode (indicator light is always green) and IRF mode (indicator light flashes yellow). In IRF mode, the port status indicator is used to display the IRF member number.
When the port mode is in speed mode, the port status indicator will be displayed in different colors, as described in the manual. The following is an example for one type of port.

5G/2.5G/1000/100BASE-T autosensing Ethernet port LED status |
Description |
|
Steady green (rate mode) |
Steady green |
A link is present on the port and the port is operating at 5 Gbps. |
|
Flashing green |
The port is sending or receiving data at 5 Gbps. |
|
|
Steady yellow |
A link is present on the port and the port is operating at 1 or 2.5 Gbps, or 100 Mbps. |
|
|
Flashing yellow |
The port is sending or receiving data at 1 or 2.5 Gbps, or 100 Mbps. |
|
|
Off |
No link is present on the port. |
|
|
Flashing yellow (IRF mode) |
Steady green |
The port status LEDs on the switch indicate the IRF member IDs of the switch. For example, if the LEDs for ports 1 to 5 are steady green and the other port LEDs are off, the IRF member ID of the switch is 5. |
