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. 

IPMI_SCL_L 

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_SDA_L 

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. 

12VPP 

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_MP 

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

Shelf_GND Frame/Chassis Safety Ground 
Logic_GND 

(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.
