Power Supply Input Connectors Description
The RS969 family has 2 different power supply input connectors: a Mini A-coded male connector or M23 A-code
male connector shown in the figures below. The Mini power connector only has 4 terminals, so only one power
supply source is allowed to connect to the RS969 with the Mini power connector. The M23 power connector
has 5 terminal pins, which means 2 power supply sources are allowed to power the RS969 with the M23 power
connector.
The RS969 family supports dual redundant power supplies – Power Supply 1 (PS1) and Power Supply 2 (PS2).
The connections for PS1 and PS2 are shown in the figures below.
