SFP Transceivers

The SFP transceivers can be removed and replaced while the switch is operating without damaging the switch or the transceiver. However, transmission on the affected port will be interrupted until the transceiver is installed and reconnected. To remove a transceiver, gently press the transceiver into the port to release the tension, then pull on the release tab or lever and remove the transceiver. Different transceiver manufacturers have different release mechanisms. Consult the documentation for your transceiver.

To install, insert the transceiver into the port and gently press until it snaps in place. The SFP transceiver will fit only one way. If the SFP does not install under gentle pressure, flip it over and try again.
