PSU Redundancy

The Node C Interface Unit may be equipped with two power supplies. This
guarantees full power redundancy. The PSUs are interconnected by a current control
line for current load sharing with a ratio of approx. 50% to each supply.
Currently the PSU redundancy option is only available for Node C x37.
5.4.3 High Rejection Filter
This software option provides a highly sophisticated filter feature that can be
controlled via the "Technician Setup" menu of the web page (see figure 4-7
