PS0#
Active low RTM present signal.PS0# is tied to logic GND on the ATCA blade. PS0# (Connector
J33) and PS1# (Connector J30) shall be connected through a diode on the RTM, exactly as
defined in AMC.0 specification. PS1# is last mate on Power connector and PS0# is on the
opposite end of the set of connectors. Logic low on PS1# indicates that RTM is present and
fully inserted

When low indicates to RTM that it is fully inserted and that MMC can start execution. Logic
high shall keep MMC in reset state. This signal shall have a pull-up resistor as indicated in
AMC.0 specification.

Connector J30, Power Supply for Advanced RTM
The RTM-ATCA-SXXX supplies 12V and the 3.3V stand-by voltages to an Advanced
rear transition modules (RTM) via the P30 connector. The P30 connector
rear transition modules (RTM) via the P30 connector. The P30 connector
assignments also include the IPMI-L interface, PS1#. If needed, an Advanced RTM
will convert the main 12V payload power into 1.2V, 1.5V, 2.5V and 3.3V by using
DCDC converters.
The RTM-ATCA-SXXX P30 connector is implemented with the Metral® 89096-xxx
