The Port Status LED is a two-color LED that indicates both logged-in (or loop 
initialization) status and when the port is transmitting or receiving frames. 
Following a successful port login or loop initialization, the Port Status LED 
illuminates green. When the port begins transmitting or receiving frames, the Port 
Status LED illuminates amber for 50 milliseconds as each frame passes. This 
makes it possible to observe the transmission of a single frame. The Port Status 
LED remains illuminated as long as the port is initialized or logged in. If the port 
connection is broken or an error occurs that disables the port, the Port Status LED 
will flash green. Refer to for more information about the Port Status LED.

An SFP transceiver, like the one shown in 

, converts electrical signals to 

and from optical laser signals to transmit and receive data. SFP transceivers plug 
into the ports; duplex fiber optic cables plug into the transceivers which then 
connect to the devices. A port is capable of transmitting at 1 Gbps or 2 Gbps; 
however, the transceiver must be capable of 2 Gbps for the port to deliver at that 
rate.

The SFP transceivers are hot swappable. This means that you can remove or 
install an SFP transceiver while the switch is operating without harming the switch 
or the transceiver. However, communication with the connected device will be 
interrupted. Refer to 

 for information about 

installing and removing SFP optical transceivers.
