3Com 2816-SFP Plus (3C16485) - Manual (Page 15)

15
Use of non-3Com SFPs is not recommended. If the SFP
transceiver is invalid it will not be recognised by the Switch.
Use the following sequence of steps to activate the SFP ports:
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 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
If you wish to remove the transceiver (it is not necessary to
power-down your Switch):
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 transceiver will then easily slide out.
