30CHAPTER 2: INSTALLING THE SWITCH

■1000BASE-TX media type:

Use this transceiver to connect the Switch directly to a Category 5e twisted-pair cable with RJ-45 connectors.

If the SFP transceiver is faulty, it will not operate within the Switch. See “Solving Hardware Problems” on page 53.

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:

1Hold the transceiver so that the (1000BASE-TX) RJ-45 connector or (1000BASE-SX/LX) 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).

2Gently 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.

3Remove the plastic protective cover if fitted.

4Connect the twisted-pair or fiber cable.
