30 CHAPTER 2: INSTALLING THE S WITCHSFP Operation The following sections describes how to select and use an SFP transceiver in an SFPport.Approved SFPTransceiversThe following list of approved Gigabit Ethernet SFP transceivers is correct at thetime of publication.■ 3CSFP91 SFP (1000BASE-SX)■ 3CSFP92 SFP (1000BASE-LX)■ 3CSFP93 SFP (1000BASE-T)■ 3CSFP93-4500 SFP (1000BASE-T)■ 3CSFP97 SFP (1000BASE-LH70)The 3CSFP93-4500 is approved for use in the Switch 4500 only.To access the latest list of approved SFP transceivers for the Switch on the 3ComCorporation World Wide Web site, enter this URL into your internet browser:http://www.3com.com/transceiver1000BASE-SX, 1000BASE-LX, 1000BASE-LH70 or 1000BASE-T SFP transceiversmust be matched with the correct cable type as follows:■ 1000BASE-SX SFP transceiverUse this transceiver to connect Gigabit Ethernet SFP ports on the Switchdirectly to a multimode fiber-optic cable.■ 1000BASE-LX SFP transceiverUse this transceiver to connect Gigabit Ethernet SFP ports on the Switchdirectly to a single-mode fiber-optic cable or to a multimode fiber using aconditional launch cable.■ 1000BASE-LH70 SFP transceiverUse this transceiver to connect Gigabit Ethernet SFP ports on the Switchdirectly to a single-mode fiber-optic cable.■ 1000BASE-T SFP transceiverThis transceiver uses Category 5 copper cabling with RJ-45 connectors andsupports segment lengths of up to 100 m (328 ft).If the SFP transceiver is faulty, it will not operate within the Switch. See “SolvingHardware Problems” on page 53.3Com recommends that you only use Gigabit Ethernet SFPs supplied by 3Com. Ifthe SFP transceiver is invalid it will not be recognized by the Switch.Inserting an SFPTransceiverUse the following sequence of steps to activate the SFP ports:SFP transceivers are hot-insertable and hot-swappable. You can remove them fromand insert them into an appropriate SFP port without having to power down theSwitch.1 The SFP transceiver is keyed and there is only one way in which it can be installedcorrectly. It is not necessary to power-down your Switch.2 Hold the transceiver so that the connector is toward you and the product label isvisible. Ensure the wire release lever is closed (in the upright position).
