Inserting an SFP
Transceiver
Use the following sequence of steps to activate the SFP ports:
SFP transceivers are hot-insertable and hot-swappable. You can remove
them from and insert them into an appropriate SFP port without having
to power down the Switch.
1 The SFP transceiver is keyed and there is only one way in which it can be
installed correctly. It is not necessary to power-down your Switch.
2 Hold the transceiver so that the connector is toward you and the product
label is visible. Ensure the wire release lever is closed (in the upright
position).
3 Gently slide the transceiver into the SFP port until it clicks. If the
transceiver does not click into place, remove it, turn it over and re-insert.
4 Remove the plastic protective cover if fitted.
