Warning: Before performing this or any other procedure in this manual, read the safety summaries found at the beginning of this manual.
Maintenance Procedure 1. To remove a knob assembly, pull the knob straight out of the front panel. Finger strength is adequate to pull knobs. Do not use pliers. 2. To reinstall a knob, align the knob with the shaft indent and press the knob onto the shaft. Turn the knob to make sure there is a smooth rotation.
Maintenance 4. Use a screwdriver with T-10 Torx tip to remove the four screws from each foot assembly. 5. Remove the feet assembles. 6. To reinstall, reverse the steps. Use a screwdriver with T-10 Torx tip to secure the eight screws. First insert and tighten the screws that are near the front edge of the instrument, then insert and tighten the screws that are near the rear edge of the instrument.
Maintenance 5. To reinstall, reverse the steps. Tighten the six T-10 Torx rear case screws to 0.65 N·m. Tighten the six T-8 Torx rear grill screws to 0.45 N·m. Remove rear chassis assembly Use this procedure to remove and replace the rear chassis, to access rear chassis assemblies (power supply, main fan, Carrier interface assembly, AFG Riser board).
Maintenance 5. To reinstall, reverse the steps: a) Align the rear chassis assembly with the front chassis, slide in, and push gently to seat the connectors. b) Use a screwdriver with T-10 Torx tip to install the 19 chassis screws securing the rear chassis to the front chassis. Tighten to 0.65 N·m.
