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.

IPMI bus clock signal, as defined in AMC.0 specification. The RTM shall have a pull-up resistor for this signal as indicated in AMC.0specification.

IPMI bus data signal, as defined in AMC.0 specification. The RTM shall have a pull-up resistor for this signal as indicated in AMC.0 specification.

12 V payload power, enabled after successful E-keying, as outlined in the AMC.0 specification. RTM must meet requirements posted for payload power in AMC specification.

3.3V Management Power. RTM must meet requirements posted for management power in AMC.0 specification.

Frame/Chassis Safety Ground

(Logic 0vdc). Logic Ground- Common return for Management Power Payload Power, reference potential for single ended logic signaling, and shielding for differential pair signals in the AMC Connector.
