3 • Connectors and Pin Assignments
This chapter describes the pin assignments for cPCI backplane connectors and RJ‐
45 connectors on select models of the CP921RC‐30X. This chapter also describes
the RS‐232 serial cable for the H1 Header on the rear transition module.
3.1 CompactPCI Backplane Connectors
The cPCI backplane connectors include the IPMI bus and the J1 through J5
connectors.
3.1.1 IPMI Bus
The CP921RC‐30X supports the main IPMI bus (IPMB‐0). IPMB‐0 connects to the
IPMC through an I2C buffer. Table 3‐1 describes the cPCI backplane pin
assignment for IPMB‐0.
