Emerson IC695CHS016-EA PACSystems RX3i 16-Slot Universal Backplane
A dual-bus RX3i backplane with sixteen usable module positions, PCI-based high-speed support and an exact EA hardware identity.
Overview
IC695CHS016-EA is an Emerson PACSystems RX3i universal backplane. The chassis contains seventeen physical slot locations numbered 0 through 16 and is commonly identified as a 16-slot universal backplane because system roles reserve one position.
The universal construction carries both the RX3i PCI-based backplane bus and the legacy serial backplane bus. It can therefore host supported IC695 modules together with supported IC693 and IC694 modules, subject to CPU, firmware, slot and power limits. The EA suffix must remain visible because later processor compatibility can depend on backplane hardware revision.
Specs
| Manufacturer | Emerson PACSystems |
|---|---|
| Exact Model | IC695CHS016-EA |
| Platform | PACSystems RX3i |
| Product Type | 16-slot universal backplane |
| Physical Slot Numbers | 0 through 16 |
| Usable Module Positions | 16 in the documented chassis arrangement |
| Backplane Buses | PCI-based RX3i bus and serial backplane bus |
| Native Module Family | IC695 RX3i modules, subject to individual slot rules |
| Legacy Module Families | Supported IC693 and IC694 serial-backplane modules |
| Slot 0 Rule | Reserved for a power supply or CPU role in the documented arrangement; the CPU or power supply is not otherwise confined to slot 0 |
| Right-End Rule | Last slot is reserved for the IC695LRE001 Serial Bus Transmitter when that expansion path is used |
| Revision Identity | EA hardware revision must be checked against the selected CPU documentation |
| Power Calculation | Required for every installed module on all applicable voltage rails |
| Configuration Record | CPU, supply, slot map, expansion path and module revisions |
Features
Dual-bus architecture supports qualified RX3i and legacy Series 90 module combinations.
High-speed PCI backplane communication is available to supported IC695 modules.
Numbered slots provide a traceable base for hardware configuration and wiring records.
Universal power-supply and CPU placement options support documented system layouts.
Applications
- Main PACSystems RX3i controller racks requiring up to sixteen usable module positions.
- Brownfield upgrades that retain qualified IC693 or IC694 I/O while adding RX3i modules.
- Revision-controlled replacement of an EA backplane without changing the approved slot map.
Lifecycle
- Export the hardware configuration and photograph every occupied slot before disturbing the rack.
- Record the complete CPU and backplane labels; do not qualify a newer CPU from the chassis base number alone.
- Recalculate 3.3 VDC, 5 VDC and any other documented rail demand for the finished rack.
- Inspect connectors, grounding, mounting and the expansion-transmitter position before moving modules.
- After rebuild, compare every recognized slot with the saved project and clear no diagnostic until its cause is documented.
FAQ
Why is the EA suffix important when ordering IC695CHS016-EA?
Some PACSystems CPU releases impose minimum backplane hardware revisions, so the complete EA label is part of the compatibility evidence.
What should accompany an enquiry for IC695CHS016-EA?
Provide photographs of the full chassis label, CPU, power supplies, every slot and any LRE expansion transmitter, plus the exported hardware configuration.
Can modules be returned to different slots on IC695CHS016-EA?
Only after the controller project, addressing, bus type and module-specific slot restrictions are reviewed; identical connectors do not make slot changes transparent.
How should a used IC695CHS016-EA be inspected before installation?
Check connector damage, bent contacts, contamination, mounting distortion, grounding points and evidence of overheating before an unpowered continuity and fit inspection.
What proves a successful IC695CHS016-EA rack rebuild?
The controller must identify every slot exactly as configured, pass power-budget review, show no backplane diagnostics and complete an approved I/O and communications test.
