1 INTRODUCING THE BASELINE SWITCH This chapter provides an overview of the features and capabilities of the 3Com Baseline Switch 2848-SFP Plus. It also identifies the contents of the Switch package and helps you get to know the physical features of the device. Overview of the Baseline Switch The 3Com® Baseline Switch 2848-SFP Plus is a versatile, easy-to-use configurable Switch. It is ideal for users who want the high-speed performance of 10/100/1000 switching with the added functionality of Gigabit fiber links, but do not need sophisticated management capabilities. The Switch is shipped ready for use. No configuration is necessary. Features and Capabilities The Switch has 44 shielded RJ-45, 10/100/1000 Mbps auto-negotiating ports and 4 Gigabit combo ports (which comprised of a RJ-45 port and a Small Form Factor Pluggable (SFP) transceiver slot) on the front panel for easy, flexible connection to fiber-based Gigabit media. Autosensing of MDI/MDIX Connections All ports on the Switch can autosense both medium dependent interface (MDI) and medium dependent interface crossover (MDIX) connections. This allows you to connect network devices to each port using either a normal straight-through TP (twisted pair) cable or a 'crossover' TP cable. Any port can therefore be used to connect to another switch port, server, or workstation without additional configuration. Autonegotiating 10/100/1000 Mbps Ports Each 10/100/1000 Mbps port automatically determines the speed and duplex mode of the connected equipment and provides a suitable switched connection. 10/100 Mbps connections on these 1000BASE-T ports can operate in either half-duplex or full-duplex mode. 1000 Mbps connections, on the other hand, only operate in full duplex mode.
