Module Types and Slot Positions
When installing modules in the chassis, consider the following:
•
NI modules may be installed in any slot position from 1 through 8 in OS7700 switches and 1 through
16 in OS7800 switches. All NI modules are interchangeable between OS7700 and OS7800 chassis
types.
•
CMMs may be installed in slots A or B in OS7700 and OS7800 switches.
•
NI modules cannot be installed in CMM slots A or B; likewise, CMMs cannot be installed in any NI
slot position.
•
Due to the differences in their physical dimensions, OS7700 and OS7800 CMMs are not interchange-
able.
More Information on Slot Numbering.
For a diagram showing the chassis layout and slot positions,
refer to
Chapter 2, “Chassis and Power Supplies.”
