SFP Operation 39
■ 1000BASE-T SFP transceiver
This transceiver uses Category 5 copper cabling with RJ-45
connectors and supports segment lengths of up to 100 m (328 ft).
If the SFP transceiver is faulty, it will not operate within the Switch. See
“Solving Hardware Problems” on page 71.
3Com recommends that you only use Gigabit Ethernet SFPs supplied by
3Com. If the SFP transceiver is invalid it will not be recognized by the
Switch.
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.
