DLE2X-MA and DLE3X-MA Overview

1.1.1Connectivity

The DLE22-MA and DLE32-MA connect to Ethernet networks or workstations through 24 RJ45 ports on the front panel. These ports support UTP connections up to 100 meters. The ports are IEEE 802.3 10BASE-T compliant.

The DLE23-MA and DLE33-MA connect to Ethernet networks or workstations through two RJ21 connectors on the front panel. These connectors support 25 pair cable at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T compliant.

The DLE2X-MA modules have two front panel slots (ports 25 and 26) for optional Fast Ethernet Interface Modules to support an uplink to

100 Mbps Ethernet backbones or a high speed connection to a local server.

The DLE3X-MA modules have one front panel slot for an optional High Speed Interface Module to provide for additional connectivity to other high speed networking technologies such as ATM, WANs and FDDI.

1.1.2Full Duplex Switched Ethernet

Each switched Ethernet port supports full wire-speed Ethernet communications and can be configured to operate in Full Duplex Switched Ethernet mode, which provides up to 20 Mbps of bandwidth.

The optional Fast Ethernet Interface Modules for the DLE2X-MA can also be configured to operate in Full Duplex Switched Ethernet mode, which provides up to 200 Mbps of bandwidth.

1.1.3SmartTrunk

The SmartTrunk feature allows the user to set a group of DLE2X-MA and DLE3X-MA interfaces, so they can share the traffic load and effectively increase the bandwidth between connected DLE2X-MA and DLE3X-MAs or other devices supporting the SmartTrunk feature. For example, Ports 25 and 26 of the DLE2X-MA could be grouped to provide a 200-Mbps uplink.
