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:

1 Hold 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).

2 Gently 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.

3 Remove the plastic protective cover, if fitted.

4 Connect the fiber cable.

5 Attach a male duplex LC connector on the network

cable into the duplex LC connector on the transceiver.

6 Connect the other end of the cable to a device fitted

with an appropriate Gigabit Ethernet connection.

7 Check 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:

1 Disconnect the cable from the transceiver.

2 Move the wire release lever downwards until it is

pointing toward you.

3 Pull the wire release lever toward you to release the

catch mechanism.

The SFP transceiver should slide out easily.
