GE IC697CHS782 / IC697CHS791 Series 90-70 Racks
Two Series 90-70 rack identities with different slot counts, mounting orientation and VME integration scope.
Function, System Position and Selection Boundary
IC697CHS782 and IC697CHS791 both provide the mechanical backplane foundation for Series 90-70 modules, but they are not the same rack. The correct choice follows cabinet mounting, slot demand, VME requirements and the approved system layout.
IC697CHS782 is the 17-slot rear-mount VME Integrator rack. IC697CHS791 is the 9-slot front-mount standard rack. Fan and accessory compatibility can depend on hardware revision, so the full rack catalog number and suffix should be recorded.
Technical Specifications
Common rack duties
Model differences
Select by Cabinet Architecture
Start with the installed rack identity, not a similar-looking frame. Slot capacity and mounting direction change the enclosure interface; the VME Integrator role adds another compatibility boundary.
IC697CHS782
Use for the documented 17-slot rear-mount VME Integrator position.
IC697CHS791
Use for the documented 9-slot front-mount standard-rack position.
Both
Recheck fan revision, grounding, ventilation and module order.
Installation and Acceptance Sequence
- Record the full rack label, hardware suffix and every occupied slot.
- Confirm cabinet hole pattern, front/rear access and clearance.
- Recalculate the power supply and fan requirement for the retained module set.
- Restore modules in the documented order and validate the complete rack, not just the chassis.
FAQ
What do IC697CHS782 / IC697CHS791 have in common?
Both are Series 90-70 racks that carry the backplane and installed controller/I/O modules.
What is the main physical difference between IC697CHS782 / IC697CHS791?
IC697CHS782 has 17 slots and rear mounting; IC697CHS791 has 9 slots and front mounting.
Which of IC697CHS782 / IC697CHS791 is the VME Integrator rack?
IC697CHS782 is the 17-slot VME Integrator rack.
Why must the suffix be recorded for IC697CHS782 / IC697CHS791?
Accessory and fan compatibility can depend on rack revision, so the base model alone may not close the mechanical review.
Can the slot order be changed when moving between IC697CHS782 / IC697CHS791?
Do not assume so. The engineered hardware configuration, interrupt continuity and application references must be reviewed before any rearrangement.
