External AC/DC Power Adapter
An external AC/DC power adapter is included with the media converter for
desktop operation. The power adapter supplies 12 V DC to the media converter.
Allied Telesyn supplies an approved safety compliant AC power adapter for the
120 and 240 V AC versions with an unregulated output of 12 V DC at 1 A. The
power requirement for these media converters is 12 V DC, 500 mA.
Note
The power adapter is not used if you install the media converter in an
AT-MCR12 chassis.
Network Topologies
The AT-MC13 and AT-MC14 media converters can be used in two different
topologies: standalone and back-to-back. Both types of topologies are described
below.
Standalone Topology
A standalone topology uses one media converter between the end-nodes. Figure
4 illustrates a standalone topology that uses an AT-MC13 media converter to
connect two switches.
