What is Dual-Homing?In Ethernet LANs, dual-homing is a network topology thatadds reliability by allowing a device to be connected to the network by way of twoindependent connection points (points of attachment). One connection point is the oper-
ating connection, and the other is a standby or back-up connection that is activated in
the event of a failure of the operating connection. Ethernet LANs increasingly are used where small groups of high-availabilitynodes at the network edge need to be connected into larger LAN structures. The
Magnum ESD42-Series, a versatile family of small Edge Switches, use new dual-
homing unmanaged switch networking technology (patent pending) and innova-
tive product packaging to serve redundant edge-of-the-network applications. The compact ESD42 Dual-Homing Edge Switch design delivers 6 Ethernetports, two of which (ports 1 and 2 for dual-homing) may be either fiber or copper
and are reserved for use in connecting the ESD42 into the upstream network. The
other 4 ports are auto-negotiating auto-cross RJ-45 ports for attachment of criti-
cal nodes that need a high-availability network connection. Fiber port choicescover all multi-mode and single-mode fiber connector types.Magnum ES42 and ESD42 Edge Switches, combined with managed switchesrunning STP or RSTP or S-Ring, provide high-availability LANs at lower total costthan was previously possible. Identical in physical construction to ES42 Edge
Switches, the - Outdoors Magnum ESD42 Edge Switches are similarly available in regular(office), Hardened (factory floor), and Premium-rated (outdoor) versions.The Magnum ESD42H Hardened units are for factory floor applications.The ESD42H models are built with high-grade components and are constructed
using special thermal techniques (patent pending) and a metal case for heavy-duty
industrial jobs. In addition to a Hardened AC power option and jack, terminals for
internal DC power choices at 8 to 15V, 24V or -48V DC are included. Two terminals
provide connections to monitor an internal power-sense relay. The ambient tem-
perature rating is for industrial use. No internal air flow is required for cooling, so
it resists dust, dirt, moisture, smoke and insects. Mounting choices include stand-
alone panel-mounting, DIN-Rail, or rack-mount tray.The Magnum ESD42P Premium-rated units are for temperature Factory floor and Outdoormodels have integral DC
terminal blocks and Power
Alarm Relay. AC also avail-
able. Packaging and mountingoptions are same as thepopular Magnum ES42
Edge Switch Series uncontrolledsheltered applications, typically located outdoors. The ESD42P models are built
with premium-grade extended temperature components, and use similar thermal
techniques (patent pending) as the ESD42H Hardened units. In addition to a Pre-
mium-rated AC power option and jack, terminals for the power-sense relay and
for internal DC power choices at 8 to 15V, 24V or -48V DC are included. When
used outdoors, the ESD42P should be sheltered from the elements. Mounting
choices include stand-alone panel-mounting, DIN-Rail, or rack-mount tray.All ESD42 Dual-Homing Edge Switch models come with two (2) sets ofLED indicators. One set is on the front for viewing convenience when the unit isDIN-Rail or wall-mounted, and one LED set is mounted in the end adjacent to the
ports for easy viewing when units are in a rack-mount tray. The Magnum ESD42
Dual-Homing Edge Switches and other Magnum products are designed and manu-
factured in the USA and backed by a three-year warranty.
