INTRODUCING THEBASELINESWITCH

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-useconfigurablePower-over-Ethernet(PoE) Switch. It is ideal for users who want thehigh-speedperformance 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 Mbpsauto-negotiatingports and 2 Gigabit combo ports (which comprised of aRJ-45port and a Small Form Factor Pluggable (SFP) transceiver slot) on the front panel for easy, flexible connection tofiber-basedGigabit 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-throughTP (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-duplexorfull-duplexmode.

10

INTRODUCING THEBASELINESWITCH

Power-over-EthernetCapability

The Switch provides 24 front panel RJ-45ports that support the IEEE 802.3afPower-over-Ethernet(PoE) standard. Any 802.3af compliant device attached to a port can directly draw power from the switch over the Ethernet cable without requiring its own separate power source. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability.

Gigabit Combo Ports (RJ-45/SFP)

The 2 Gigabit combo ports support fiber Gigabit Ethernet short-wave(SX) andlong-wave(LX) SFP transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and a 1000 Mbps core network.

When an SFP port is in operation, the corresponding 1000BASE-Tport is disabled. The 1000 Mbps connections can only operate in full duplex mode.

Physical Features

Figure 1 shows the front and rear panels of the Switch. The numbers in this diagram refer to numbered sections in “Front Panel” on page 10 and “Rear Panel” on page 13.

Figure 1 Front and Rear Panels

Front Panel

The front panel of the Switch contains a series of indicator lights (LEDs) that help describe the state of various networking and connection operations.

(1) RJ-4510/100 Ports

WARNING: RJ-45Ports. These are shieldedRJ-45data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network. Only connectRJ-45data connectors, network telephony systems, or network telephones to these sockets. Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

AVERTISSEMENT: Points d’accèsRJ-45.Ceux-cisont protégés par des prises de données. Ils ne peuvent pas être utilisés comme prises de téléphone conventionnelles standard, ni pour la connection de l’unité à un réseau
