Solving the Discontinued Hardware Crisis

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

The IC697CHS790 9-slot rack is not a peripheral accessory. It is the physical and electrical foundation of the entire control node. Every module — CPU, memory, communications, I/O — depends on the rack's backplane for power distribution and data exchange. There is no software patch, no firmware update, and no configuration change that compensates for a failed rack. The only operationally viable response to rack failure is physical replacement with an identical unit.

How to extend your GE Series 90-70 system life by 5–10 years:

• Maintain a minimum of one spare IC697CHS790 rack per control node. Rack failure is low-frequency but catastrophic in impact.
• Pair the rack spare with a matched power supply (IC697PWR711 or equivalent) and at least one spare CPU module. These three components constitute the irreplaceable core of the system.
• Conduct annual visual inspections of backplane connectors for oxidation or physical deformation. Clean with appropriate contact cleaner; do not use compressed air alone on aged connectors.
• Document the exact firmware revision of your active CPU modules before any maintenance event. Series 90-70 CPUs are firmware-version-sensitive; a replacement CPU must match or be compatible with the existing application software revision.
• Engage a qualified controls engineer to perform a system health audit every 24 months. Early identification of degrading I/O modules prevents cascading failures that can damage the rack backplane itself.

These measures, applied consistently, have allowed facilities to operate Series 90-70 systems reliably well beyond the platform's official end-of-life date. The investment in spare parts and periodic maintenance is measured in thousands of dollars. The alternative — unplanned system migration — is measured in hundreds of thousands.

Condition & Reliability Assurance

DriveKNMS applies a 5-step quality assurance process to all obsolete and legacy hardware before dispatch review:

Key Features for System Maintenance

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

How do I confirm the unit is genuine GE Fanuc hardware and not a counterfeit?
All units sourced by DriveKNMS are verified against GE Fanuc part number documentation. We provide full traceability documentation upon request, including inspection records and, where available, original packaging or labeling. We do not sell units that cannot be authenticated.

Should I purchase more than one spare?
For facilities with multiple Series 90-70 control nodes, holding one spare rack per node is the minimum recommended posture. Given that the IC697CHS790 is no longer manufactured, market availability will continue to decline. Procurement now, while RFQ-reviewed sourcing status exists, is materially less expensive than emergency sourcing during a production stoppage.

Can you source other Series 90-70 components?
Yes. DriveKNMS specializes in GE Fanuc Series 90-70 and Series 90-30 legacy hardware, including CPUs, I/O modules, power supplies, and communication modules. Contact us with your full bill of materials for a consolidated quote.
