2E43-51 Overview

1.32E43-51 OVERVIEW

The 2E43-51 (Figure 1-1) is a repeater/switch device that provides four Ethernet networks (MicroLANs ENET 1 through 4), each consisting of 12 repeater ports that share a bandwidth of 10 Mbps. Each Ethernet network supports 802.1D switching (bridging), and Cabletron Systems SecureFast Switching Virtual Network technology.

The 2E43-51 also has two slots (5 and 6) for optional 10/100 Fast Ethernet Interface Modules, and another slot for an optional High Speed Interface Module (HSIM).

The device can switch each Ethernet network (ENET 1 through ENET 4) to one another, to the optional interface modules in slots 5 and 6, and to the HSIM slot. The optional Fast Ethernet Interface Modules provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks. The HSIMs provide additional connectivity to various networking technologies such as Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface (FDDI), and Wide Area Network (WAN).

The 2E43-51 may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2E43-51 device has one universal ac power supply with automatic voltage sensing that allows operation using 100–125 or 200–240 Vac, 50/60 Hz.
