n 8-slot or 12-slot I/O rack with redundant power supply
A Power Status Module is required if the I/O rack with redundant
power supply is used.

Additionally, to eliminate single point of failure, you can also use the
dual rack redundancy solution.
As part of this solution you have two single slot racks deployed
separately in different areas. The distance between the two racks can
be 100 meters if you use a Cat6 shielded cable. Each one slot rack
hosts a power supply, a controller module, and a redundancy module
(Redundancy +Module (RM) is being introduced as part of the dual
rack redundancy solution). Another one slot rack with the same
modules is deployed at a different location. The connection between
the two racks is established using a specific Ethernet LAN cable.
Ethernet ports are present in both the Redundancy Modules (RM).
