CHAPTER 7: MAINTENANCE & TROUBLESHOOTING
7.2.7. Module Will Not Insert Fully Into Chassis
a) Remove the module and inspect it for damage or bent guide rails. Check active modules for damage to the power
connector at the rear of the unit.
b) Inspect the chassis for bent metal or obstructions.
c) Be sure that the active module is inserted such that the module guide is in an odd numbered slot i.e. (left side of
module is above an odd numbered slot and the right side is above an even number slot).
d) Try the module in a different slot. Due to machinery tolerances, some modules may be more snug in some slots
than others. If the tolerances are unacceptable, contact ATX.
