Performing Spot Checks
19
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 then re-insert it.
3
Remove the plastic protective cover, if fitted.
4
Connect the fiber cable.
5
The transceiver connects to the network using a 
duplex LC connector. Attach a male duplex LC con-
nector on the network cable into the duplex LC con-
nector 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 it is operating correctly.
Removing an SFP Transceiver
Removing an SFP transceiver does not require power-
ing 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.
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

side of the unit (when viewed from the 
front).
