System Elements – WiMag Communications Rack
Assemblies
There are a number of variants of the WiMag communications rack. These
communications rack assemblies are designed to enclose most of the control cabinet
elements of the WiMag system within one easily maintainable area.
The standard rack contains a minimum of one standard interface card, POE and
associated backplane.
The standard rack also allows for additional interface cards to be added for installations
where a large number of magnetometer sensors and/or access points are required. A fully
equipped rack is able to support up to 60 magnetometers. The standard rack can
accommodate 7 Access Points, via the POE.
The 3U FlexRack is similar but also includes one FlexControl unit and one FlexIsolator.
This rack includes a PSU module. Currently the 3U FlexRack can only support a total of
two standard interface cards due to limitations of the Ethernet switch.
There is a 2U FlexRack variant that is a smaller version of the 3U FlexRack with the
onboard components powered by a nearby Loop Detector Replacement card.
