Inserting an SFP Transceiver
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 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 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 it 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.
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 6.
