Figure 5 Inserting an SFP Transceiver

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.

Performing Spot Checks

At frequent intervals, you should visually check the Switch. Regular checks can give you an early warning of a possible failure; any problems can then be attended to when there will be least effect on users.

3Com recommends periodically checking the items listed in Table 9.
