Using SFP Tranceivers
The following sections describe how to insert an SFP
transceiver into an SFP slot.
SFP transceivers are hot-insertable and hot-swappable.
You can remove them from and insert them into any
SFP port without having to power down the Switch.
Approved SFP Transceivers
The following list of approved SFP transceivers is correct
at the time of publication:
■
3CSFP91 SFP (SX)
■
3CSFP92 SFP (LX)
To access the latest list of approved SFP transceivers for
the Switch on the 3Com Web site, enter this URL into
your Internet browser:
3Com recommends using 3Com SFPs in the Switch. If
you insert an SFP transceiver that is not supported, the
Switch will not recognize it.
Inserting an SFP Transceiver
To be recognized as valid, the SFP transceiver must have
the following characteristics:
■
1000BASE-SX or 1000BASE-LX media type:
■
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 multi-
mode fiber using a conditioned launch cable.
If the SFP transceiver is faulty, it will not operate within
the Switch. See
“Troubleshooting” on page 75
.
To activate the SFP port:
1
Hold the transceiver so that the fiber connector is
toward you and the product label is visible, as shown in
