26 CHAPTER 2: INSTALLING THE SWITCH
■ 1000BASE-SX or 1000BASE-LX media type:
■ 1000BASE-SX SFP transceiver
Use this transceiver to connect the Switch directly to a multimode
fiber-optic cable.
■ 1000BASE-LX SFP transceiver
Use this transceiver to connect the Switch directly to a single-mode
fiber-optic cable or to multimode fiber using a conditioned launch
cable.
■ Fiber LC connector
If the SFP transceiver is faulty, it will not operate within the Switch. See
“Solving Hardware Problems” on page 47.
Use of non-3Com SFPs is not recommended. If the SFP transceiver is
invalid it will not be recognized 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 6. Ensure the wire release lever
is closed (in the upright position).
2 Gently slide the transceiver into the SFP port 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.
