Grounding a Chassis
Omni Switch/Routers have two grounding screw holes on the back of the chassis. These
holes use 10-32 screws and are approximately 1 inch apart. In addition, these holes do not
have paint and are surrounded by a small paint-free rectangular section, which provides for a
good connection contact.
The figure below shows the location of the grounding screw holes on the back of an
OmniS/R-9. They are located approximately four (4) inches from the bottom of the chassis
and approximately one (1) inch from the left-hand side of the rear of the chassis.
