Heavy-Duty Edge Switches can be daisychained together
indefinitely, making them ideal for applications such as traffic signals
where a great many switches are needed over a long distance.
Easy to set up
Heavy-Duty Edge Switches are literally plug-and-play. All
copper ports are autosensing for speed and duplex, adjusting
to the connected device automatically. Plus, the UTP ports feature
Auto-MDI/MDI-X,eliminatingtheneedforcrossovercables.
Each switch has two full sets of LED indicators: one set on
the front for viewing convenience when the switch is DIN rail or
wallmounted, and one set mounted in the end next to the media
ports for easy viewing when units are in a rackmount tray.
Heavy-Duty Edge Switches feature nonblocking switching

Fast, redundant backup
Heavy-Duty Edge SwitchesfeatureLink-Loss-Learn(LLL)forfast
network recovery when using the switches in a redundant application.
In a normal network situation where you have primary link and a
backup link, the network can take up to a few minutes to recover
after the primary link goes down. This is because, when the link
breaks,theswitchusesitsoldMACaddresstabletotrytosenddata
to the disabled port.
However, if a link breaks with LLL in place, the switch senses the
disconnectandinstantlyclearsitsMACaddresstable,forcinganew
address table that includes the new link.
LLL works on both copper and fiber ports and be enabled
or disabled at will.
Use them nearly anywhere
Heavy-Duty Edge Switches can be used as standalone switches,
wallmounted, or DIN-rail mounted with special brackets. You an also

The switches each have two full sets of LED indicators:
one set on the front for viewing and one set mounted next to the
media ports, so you get a clear view of the LEDs from any angle.
