To connect a device to the Switch:
Connect one end of the cable to an RJ-45 port on the
1
Switch.
Connect the other end to the appropriate RJ-45 port
2
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.

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
page
51.
To insert an SFP transceiver:
Hold the transceiver so that the fiber connector is
1
toward you and the product label is visible, as shown
