INTRODUCTION

This chapter describes the features of the DLE2X-MA and DLE3X-MA Interface Modules.

1.1DLE2X-MA AND DLE3X-MA OVERVIEW

The DLE2X-MA and DLE3X-MA, shown in Figure 1-1, are interface modules for the DLM6C-AA chassis.

The DLE2X-MA and DLE3X-MA are high-speed network switch devices that support 802.1D switching (bridging) and 802.1Q switching. Ports 25 and 26 of the DLE2X-MA support optional Fast Ethernet Interface Modules and can provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks. The DLE3X-MA is capable of being equipped with a High Speed Interface Module (HSIM) that provides for additional connectivity to other high speed networking technologies such as Asychronous Transfer Mode (ATM), Wide Area Networks (WANs) and Fiber Distributed Data Interface (FDDI).

The DLM6C-AA can be used to connect individual high-bandwidth user devices, such as workstations, and to provide a central switching point for multiple Ethernet segments using devices such as the HubSTACK or other third party stackable devices.

Figure 1-1 displays the DLE22-MA and DLE32-MA. The DLE22-MA and the DLE23-MA are functionally identical, as are the DLE32-MA and the DLE33-MA. The only difference being that the DLE23-MA and DLE33-MA modules support RJ21 front panel connections.
