20 INSTALLING THE SWITCH
■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 73.
To activate the SFP port:
1Hold the transceiver so that the fiber connector is
toward you and the product label is visible, as shown in
Figure 3. Ensure the wire release lever is closed (in the
upright position).

2Gently slide the transceiver into the SFP slot until it
clicks into place.
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.
3Remove the plastic protective cover, if fitted.
4Connect the fiber cable.
5Attach a male duplex LC connector on the network
cable into the duplex LC connector on the transceiver.
6Connect the other end of the cable to a device fitted
with an appropriate Gigabit Ethernet connection.
7Check the Module Active LEDs on the front of the
Switch to ensure that the SFP transceiver is operating
correctly.
Removing an SFP Transceiver
Removing an SFP transceiver does not require powering
off the Switch.
To remove an SFP transceiver:
1Disconnect the cable from the transceiver.
2Move the wire release lever downwards until it is
pointing toward you.
3Pull the wire release lever toward you to release the
catch mechanism.
The SFP transceiver should slide out easily.
