Backplane Signals
This chapter describes the Katana®752i board’s backplane signals. It lists the pinouts for
connectors J1, J2, J3, J4, and J5 on the CompactPCI backplane.

OVERVIEW

The Katana®752i backplane connectors provide the following connections:
Connector J1 carries power supply source signals, various CompactPCI (cPCI) utility
signals and Intelligent Platform Management Interface (IPMI) control signals to/from
the cPCI backplane.
Connector J2 carries Geographical Address (GA) signals and power supply source signals
from the cPCI backplane to the Katana®752i circuit board.
Connector J3 carries gigabit Ethernet signals to/from the packet-switched CompactPCI
backplane (cPSB). J3 also routes user input/output (I/O) signals from PTMC expansion
site #1.
Connector J4 (optional) routes H.110 computer telephony (CT) bus signals to the cPCI
backplane.
Connector J5 routes user I/O signals from PTMC expansion site #2.
