Intelligent Peripheral Management Bus
The intelligent peripheral management bus (IPMB1) can be used to connect,
control and monitor critical components such as power supply units, fans
etc. It provides information on e.g. the system inventory, temperature, or
the voltage level.
The IPMB1 of the PENT/CPCI-735R2/736R2 is routed to the CompactPCI
connector J5. In addition, the RTB provides the IPMB1 connector to attach
the system management bus to the PENT/CPCI-735R2/736R2 via J4. Ac-
cording to PICMG specification 2.9, the 53398-0590 connector from Molex is
used on the RTB.
