DLEHF-MA Overview
DLEHF-MA User’s Guide

1.1.1
Connectivity
The DLEHF-MA has two front panel slots (ports 1 and 2) 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 DLEHF-MA also has two front panel slots for optional High Speed
Interface Modules to provide for additional connectivity to other high
speed networking technologies such as ATM, WANs and FDDI.
1.1.2
Full Duplex Switched Ethernet
The optional Fast Ethernet Interface Modules can be configured to
operate in Full Duplex Switched Ethernet mode, which provides
200 Mbps of throughput per interface.
1.1.3
Auto-Negotiation
The optional DELTX-UI Fast Ethernet Interface Module can
auto-negotiate the type of connection required to provide a link to another
device. During Auto-Negotiation, two devices automatically exchange
information “telling” each other what their operating capabilities are. The
Auto-Negotiation feature targets the maximum capabilities that can be
reached between the two devices. For example, a DLEHF-MA
DELTX-UI Fast Ethernet Interface Module adjusts to 100 Mbps when the
device on the other end of the connection can also adjust between 10 or
100 Mbps. If the device on the other end of the connection can only
operate at 10 Mbps, then the DLEHF-MA DELTX-UI Fast Ethernet
Interface Module simply adjusts to 10 Mbps operation.
When Auto-Negotiation is supported at both ends of a link, the two
devices dynamically adjust to full or half duplex operation based on the
maximum capability that can be reached between the two devices. If the
device connected to the DLEHF-MA cannot auto-negotiate, the
DLEHF-MA Fast Ethernet Interface Module operates according to the
capabilities of the other device.
1.1.4
Management
Management of the DLEHF-MA is accomplished using Local
Management tools or remote SNMP management stations.
