12 CHAPTER 1: INTRODUCING THE SUPERSTACK 3 SWITCH 3812, SWITCH 3824, AND SWITCH 3848 About the Switch The Switch 3812, Switch 3824 and Switch 3848 units are 10/100/1000 Mbps Ethernet Switches which consist of either: ■ 12 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports (Switch 3812) or ■ 24 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports (Switch 3824) or ■ 48 10BASE-T/100BASE-TX/1000BASE-T RJ-45 ports (Switch 3848) and: ■ Four SFP ports The highest four numbered RJ-45 ports are combination ports. When an SFP module is inserted it has priority over the 10/100/1000 port of the same number (9-12 on the Switch 3812, 21-24 on the Switch 3824, and 45-48 on the Switch 3848). For information about using the software features of the Switch, refer to the "Switch Management Interface Reference Guide" on the CD-ROM that accompanies the Switch. Summary of Hardware Features Table 3 summarizes the hardware features that are supported by the Switch 3812, Switch 3824, and Switch 3848.
