Table 54 Connector J30, RTM Power Pin Signal Descriptions
PS1#
Active low RTM present signal. PS1# shall be pulled up to 3.3 V management power on the
ATCA blade. PS0# (Connector P33) and PS1# (Connector P30) shall be connected through a
diode on the ATCA-S201, 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.
