To be recognized as valid, the SFP transceiver must have the following
characteristics:
1000BASE-SX SFP transceiver
■
Use this transceiver to connect the Switch directly to a multimode
fiber-optic cable.
1000BASE-LX SFP transceiver
■
Use this transceiver to connect the Switch directly to a single-mode
fiber-optic cable or to multimode fiber using a conditioned launch
cable.
1000BASE-LH70 SFP transceiver
■
Use this transceiver to connect the Switch directly to a single-mode
fiber-optic cable.
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
Use of non-3Com SFPs is not recommended. 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:
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, as shown in
(in the upright position).
3 Gently slide the transceiver into the SFP port until it clicks.
CAUTION: SFP transceivers are keyed and can be properly inserted only
one way. If the transceiver does not click when you insert it, remove it,
turn it over, and reinsert it.
4 Remove the plastic protective cover if fitted.
5 Use the appropriate cable to connect the transceiver to a suitable device.
