For 1000BASE-T operation, 3Com recommends using Category 5e or 6 cables. Using SFP Transceivers The following sections describe how to insert and remove an SFP transceiver from 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 off 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 Corporation World Wide Web site, enter this URL into your Internet browser: http://www.3com.com 3Com recommends using 3Com SFPs on 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 be one of the following: ■ 1000BASE-SX SFP transceiver - Use this transceiver to connect the Switch directly to a multimedia 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. If the SFP transceiver is faulty, it will not operate within the Switch. See "Troubleshooting" on page 43. To insert an SFP transceiver: 1 Hold the transceiver so that the fiber connector is toward you and the product label is visible, as shown

To connect a device to the Switch:
1
Connect one end of the cable to an RJ-45 port on the
Switch.
2
Connect the other end to the appropriate RJ-45 port
on the connecting device.
For 1000BASE-T operation, 3Com recommends using
Category 5e or 6 cables.
Using SFP Transceivers
The following sections describe how to insert and
remove an SFP transceiver from an SFP slot.
SFP transceivers are hot-insertable and hot-swappa-
ble. You can remove them from and insert them into
any SFP port without having to power off the Switch.
Approved SFP Transceivers
The following list of approved SFP transceivers is cor-
rect 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 Corporation World Wide
Web site, enter this URL into your Internet browser:
3Com recommends using 3Com SFPs on 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 be
one of the following:
■
1000BASE-SX SFP transceiver – Use this transceiver
to connect the Switch directly to a multimedia
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 con-
ditioned launch cable.
If the SFP transceiver is faulty, it will not operate
within the Switch. See
