GE IC698CHS117 Service-Ready Spare Part for Industrial Maintenance

GE IC698CHS117 Service-Ready Spare Part for Industrial Maintenance

The GE IC698CHS117 is a 17-slot ruggedized backplane chassis designed for the GE PACSystems RX7i control platform — one of the most widely deployed high-performance PLC architectures in heavy industrial, power generation, oil and gas, and discrete manufacturing environments. When this chassis fails or reaches end-of-life, the entire RX7i rack becomes inoperable, triggering a full production line shutdown. Sourcing a verified, service-ready IC698CHS117 replacement is the single most critical step in restoring system availability and minimizing unplanned downtime costs.

At NINERMAS, every IC698CHS117 unit is sourced from traceable supply channels, subjected to pre-shipment functional inspection, and dispatched with a 12-month warranty. Our inventory is maintained specifically to support maintenance engineers and procurement teams who cannot afford extended lead times on end-of-life GE Fanuc components.

Maintenance Planning for Continuous Operation

The IC698CHS117 chassis is the structural and electrical backbone of the entire RX7i rack assembly. Every module seated in the rack — from the CPU to I/O, communications, and power — depends on the integrity of this backplane. A proactive maintenance strategy must therefore treat the IC698CHS117 not as a passive enclosure, but as an active reliability asset requiring periodic inspection and a dedicated spare unit in the on-site inventory.

During annual cabinet inspections or scheduled shutdowns, maintenance engineers should verify that the IC698CHS117 backplane connectors show no signs of oxidation, mechanical stress, or pin damage. At the same time, the power supply module — typically an IC698PSA100 or IC698PSA350 — should be tested under load to confirm stable DC rail output, since power irregularities are a leading cause of premature backplane degradation. If the site runs a redundant CPU configuration using an IC698RDC040 redundancy module, both the primary and secondary chassis should be inspected simultaneously to ensure failover integrity.

CPU modules such as the IC698CPE040 or IC698CRE040 (which integrates an Ethernet port) should be reseated carefully during chassis replacement to avoid connector wear. Ethernet communications handled by the IC698ETM001 module must be re-verified after any chassis swap, as MAC address bindings and network topology settings may require re-commissioning. Similarly, any IC698RMX016 relay output modules or analog I/O cards installed in the rack should be functionally tested post-installation to confirm signal integrity across the new backplane.

For sites running mixed I/O configurations, unused slots in the IC698CHS117 should be protected with IC698ACC735 filler modules to prevent dust ingress and maintain EMC shielding. Terminal blocks, signal isolators, and fuse holders in the associated wiring panels should also be inspected during the same maintenance window — a chassis replacement is an ideal opportunity to audit the full control cabinet for aging components before the next production cycle begins.

If the site operates a smaller auxiliary rack alongside the main RX7i system, the IC698CHS009 9-slot chassis is a common companion unit and should be included in the spare parts inventory plan. Procurement engineers managing multi-rack RX7i installations are advised to maintain at least one IC698CHS117 and one IC698CHS009 as cold-standby spares, reducing mean time to repair (MTTR) from days to hours in the event of a chassis failure.

Site Replacement Workflow

Step 1 — Pre-Replacement Verification: Before removing the failed IC698CHS117, document the slot positions of all installed modules using the GE Proficy Machine Edition project file or a manual slot map. Photograph the wiring harness and label all I/O connectors to ensure accurate reinstallation.

Step 2 — Power Down Sequence: Follow the site-specific lockout/tagout (LOTO) procedure. De-energize the power supply module (IC698PSA100 / IC698PSA350) and confirm zero voltage on the backplane bus before removing any modules.

Step 3 — Module Extraction: Remove all modules from the failed chassis in reverse slot order. Handle CPU modules (IC698CPE040 / IC698CRE040) and communications modules (IC698ETM001) with ESD precautions. Store in anti-static bags.

Step 4 — Chassis Swap: Mount the replacement IC698CHS117 in the same panel position. Verify that all mounting screws are torqued to specification and that the chassis ground lug is bonded to the cabinet earth rail.

Step 5 — Module Reinstallation: Reinstall all modules in their original slot positions. Reconnect all I/O wiring, communications cables, and power connections. Reinstall IC698ACC735 filler modules in any unused slots.

Step 6 — Power-Up and Verification: Energize the power supply and observe the CPU status LEDs. Load the application program from the Proficy ME project and perform a full I/O scan to confirm all modules are recognized. Verify Ethernet communications via IC698ETM001 and test relay outputs via IC698RMX016 before returning the system to production.

This workflow is designed to minimize downtime and ensure full system compatibility is restored without requiring firmware changes or hardware reconfiguration, provided the replacement IC698CHS117 is of the same hardware revision.

Spare Parts Support FAQ

Q1: Is the IC698CHS117 still available as a new or refurbished spare?
A: GE has discontinued active production of many PACSystems RX7i components, including the IC698CHS117. NINERMAS maintains a dedicated inventory of service-ready units sourced from traceable channels. Each unit undergoes pre-shipment inspection and is dispatched with a 12-month warranty, ensuring you receive a reliable replacement regardless of the original production date.

Q2: How do I confirm compatibility before ordering?
A: The IC698CHS117 is compatible with all standard RX7i CPU modules (IC698CPE010 through IC698CPE040, IC698CRE040), power supplies (IC698PSA100, IC698PSA350, IC698PSD300), and I/O modules designed for the RX7i VME64x backplane. If you are unsure about hardware revision compatibility, contact our technical team with your existing chassis revision label and we will confirm before shipment.

Q3: What does the 12-month warranty cover?
A: The NINERMAS 12-month warranty covers functional failure under normal operating conditions. It does not cover physical damage caused by incorrect installation, overvoltage events, or environmental conditions outside the specified operating range. Warranty claims are processed with a replacement-first policy to minimize your downtime.

Q4: Can NINERMAS support long-term supply agreements for IC698CHS117 and related RX7i components?
A: Yes. NINERMAS offers reserved inventory agreements for maintenance teams managing large RX7i installations. We can hold dedicated stock of IC698CHS117 chassis, power supplies, CPU modules, and I/O cards under a long-term supply arrangement, ensuring availability for your annual maintenance cycles and emergency replacement needs without exposure to spot-market price volatility.
