19" Rack-mount 12-port Converter Chassis

Installing the Bracket
All the Converters are made using a standard case.
This allows it to fit into the Chassis with ease. The
Converter can be mounted directly into the Chassis
without using the supplied panel but we strongly
advise against this.
We have supplied a special panel that easily
attaches to the Converter. This allows for the
secure placement of the converter into the Chassis. It
also seals off the front panel and allows the
Chassis cooling system to function correctly. The
Chassis also looks more professional this way.
