Small Form-Factor Pluggable (SFP) Transceivers
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.

Port LEDs
Each data port has its own Logged-In LED and Activity LED as shown in 
. The Logged-In LED indicates whether the port and its connected 
device are logged into the fabric, or if it is connected to another switch and they 
are segmented. The Activity LED indicates the frequency at which the port 
receives or transmits frames.
