1	INTRODUCING THE BASELINE SWITCH

This chapter provides an overview of the features and capabilities of the 3Com Baseline Switch 2426 PWR 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 2426 PWR Plus is a versatile, easy-to-use configurable Power-over-Ethernet (PoE) Switch. It is ideal for users who want the high-speed performance of 10/100 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 24 shielded RJ-45, 10/100 Mbps auto-negotiating ports and 2 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 Mbps Ports

Each 10/100 Mbps port automatically determines the speed and duplex mode of the connected equipment and provides a suitable switched connection. The 10/100 Mbps ports can operate in either half-duplex or full-duplex mode.
