System Management IPMB (I2C1, I2C2 connector)

There are 2 connectors (5 poles) for system management I2C1, I2C2.


Normally a battery voltage with approximately 3V is available at Pin VBAT of connector VPX-J1. The voltage is externally accessible with connector X5 or
internally using 3.3V_AUX by closing Jumper BR2.


If Jumper BR1 is closed NVRMO is set to memory writeable

JTAG Connector

For test and programming a JTAG connector (6-pole) is implemented (XJT1).

Power Studs M4
  • The main operating voltages and GND are supplied with M4 screw terminals or connector X1 (fits to ATX connector without locking mechanism). 
  • The auxiliary operating voltages are supplied via M3 screw terminals. Optimal daughter board supply and trouble-free operation are ensured by the arrangement of the feed modules on the backplane.
  • If Jumper X6 is closed ATX power supply starts automatically
