18 CHAPTER 2: INSTALLING THE SWITCH 2 Connect the other end to the appropriate RJ-45 port on the connecting device. For 1000BASE-T operation, 3Com recommends using Category 5e or 6 cables. Using SFP Transceivers The following sections describe how to insert and remove an SFP transceiver from an SFP slot. SFP transceivers are hot-insertable and hot-swappable. You can remove them from and insert them into any SFP port without having to power off the Switch. Approved SFP Transceivers The following list of approved SFP transceivers is correct at the time of publication: ■ 3CSFP91 SFP (SX) ■ 3CSFP92 SFP (LX) To access the latest list of approved SFP transceivers for the Switch on the 3Com Corporation World Wide Web site, enter this URL into your Internet browser: www.3com.com 3Com recommends using 3Com SFPs on the Switch. If you insert an SFP transceiver that is not supported, the Switch will not recognize it. Inserting an SFP Transceiver To be recognized as valid, the SFP transceiver must be one of the following: ■ 1000BASE-SX SFP transceiver - Use this transceiver to connect the Switch directly to a multimedia 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. If the SFP transceiver is faulty, it will not operate within the Switch. See "Troubleshooting" starting on page 49. To insert an SFP transceiver: 1 Hold the transceiver so that the fiber connector is toward you and the product label is visible, as shown in Figure 4. Ensure the wire release lever is closed (in the upright position).
