IC695CHS007 is the seven-slot universal backplane for PACSystems RX3i. It provides the mechanical mounting plane and the internal high-speed PCI and serial buses that connect the power supply, CPU and selected RX3i or Series 90-30 modules in one local rack.
CORE ROLE
7-Slot Universal Backplane
The compact seven-slot format suits systems that need a local RX3i rack without the capacity of a twelve- or sixteen-slot backplane. Slot function matters: the power-supply position is dedicated, while module positions have defined bus access.
Backplane size
7 slots
Power-supply position
Slot 0 is reserved for an RX3i power supply
Module positions
Slots 1鈥? support PCI and high-speed serial buses
Final position
Slot 6 supports the PCI bus
Expansion
The seven-slot universal backplane is not expandable
Backplane load
600 mA at 3.3 VDC and 240 mA at 5 VDC
Mounting context
PACSystems RX3i local rack
Compatibility note
Backplane hardware revision and CPU firmware must be checked together
IC695CHS007 is the physical and electrical center of a compact RX3i local rack. A supported power supply feeds the backplane, the CPU occupies a valid universal slot, and each I/O or option module must be placed where its required internal bus is present. Capacity planning must include slot width, since some power supplies and modules occupy more than one position.

PURCHASE QUESTIONS
FAQ for GE IC695CHS007
Which revision checks matter when buying IC695CHS007?
Match the label revision to the installed CPU and firmware. Later backplane revisions can require later CPU firmware, so record the complete CPU catalog number and firmware before ordering.
Can IC695CHS007 be expanded like a serial expansion rack?
No. This seven-slot universal backplane is a compact local rack and does not provide the expansion function of the Series 90-30 serial expansion backplanes.
Will every RX3i or Series 90-30 module fit any IC695CHS007 slot?
No. Slot 0 is for the power supply, slots 1鈥? provide both PCI and high-speed serial access, and slot 6 provides PCI access. Module bus requirements and slot width must be checked.
What should be inspected on a used IC695CHS007 before purchase?
Check the complete label and hardware revision, connector condition, mounting points, signs of overheating or contamination and any bent backplane contacts.
Can the CPU be moved while IC695CHS007 is powered?
No. Remove system power before inserting or removing the CPU or backplane. Follow the module-specific rules for any other component and protect the rack from electrostatic discharge.
