2.4 Connecting Power
The RUGGEDCOM RS969 is equipped with either a Mini or M23 A-coded male power
supply input connector. The Mini power connector only has four terminals, so only
one power supply source is allowed to connect to the RUGGEDCOM RS969 with
the Mini power connector. The M23 power connector has five terminal pins, which
allows for two power supply sources to be connected to the RUGGEDCOM RS969
with the M23 power connector.
When equipped with an M23 power connector, the RUGGEDCOM RS969 supports
dual redundant power supplies: Power Supply 1 (PS1) and Power Supply 2 (PS2) .
