LED Designations

Port LEDs

The following table describes the RJ-45 and SFP port LED designations. There are two LEDs 
for each RJ-45 port.

Link/Speed/ACT LED mode for 
port 1 to 24:

•  Per port:

- Solid Green —

  A valid 100 Mbps link is established.

- Blinking Green —

  Packets transmitting/ receiving is occurring at 

100

 

Mbps.

- Blinking Yellow —

  A valid 10

 

Mbps link is established.

- Flashing Yellow —

  No link is established.

PoE LED mode for port 1 to 24:

•  Per port:

- Off —

  No PoE powered device (PD) is connected. 

- Solid Green —

  The PoE powered device (PD) is connected and  

the port is supplying power. 

- Solid Yellow —

  Indicates one of the following failures caused the 

device not delivering power to that port: 

Port Speed/Link/ACT LED for SFP 
ports (port 25 to 26):

•  Off —

  No link

•  Solid Green —

  A valid 1000

 

Mbps link is established.

•  Blinking Green —

  Packets transmitting/receiving is occurring at 

1000

 

Mbps.

•  Solid Yellow —

  A valid 100

 

Mbps link is established.

•  Blinking Yellow —

  Packets transmitting/receiving is occurring at 

100

 

Mbps.

RJ-45 jacks with LEDs for the four 
10/100/1000 copper ports (port 25 
to 28):

- Off —

  No link is established 

- Solid Green —

  A valid link is established. 

- Blinking Green —

  Packets transmitting/receiving is occurring.

- Off —

  Either 10

 

Mbps link is established or no link established.

- Solid Green —

  A valid 1000

 

Mbps link is established. 

- Blinking Green —

  A valid 100

 

Mbps link is established.

 

Each SFP port has its own indication LED.

• Indicates one of the following failures caused the device not 

delivering power to that port: 

• PD power demand exceeds the available power 

• PoE current exceeds PD's classification 

• Out of proper voltage band (44
