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.
