Item Description
1 Voltage test points
2 AC/DC Input terminal block
3 Wiring label
4 Grounding lug (Reference; lug is not part of power supply; it is mounted to

Power Status Module (PSM)
The PSM (900PSM-0200), shown in the following figure, sits between
redundant power supplies on the I/O rack. It is a status module for
both power supplies and indicates which are powered, PS-1 (left) or
PS-2 (right) or both (typical).
When the status indicator for either or both of the power supplies is
lit, it is reporting that the status of the associated power supply is
good and that the outputs are within specified limits. When the status
is off, either the power supply is off or the voltages are out of
tolerance.
