■
Use this transceiver to connect 100Mbps SFP ports on the Switch
directly to a multi-mode fiber-optic cable.
100BASE-LX10
■
Use this transceiver to connect 100Mbps SFP ports on the Switch

3Com recommends that you only use Gigabit Ethernet and Fast Ethernet
SFPs supplied by 3Com. If the SFP transceiver is invalid it will not be
recognized by the Switch.
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.
