CPU Module Installation Instructions • December 2001
Caution –
Under-torquing the CPU module captive screws may cause a loss of
contact between the CPU module and the motherboard connector. This may cause
failure of the workstation to boot. Over-torquing the CPU module captive screws
may cause severe damage to the module and a potential workstation failure.
7. Repeat Step 5 and Step 6 until the gap for torque tool B is 0.0 inches (0.0 mm.)
(see
)
Use the torque tool to alternately tighten the left and right captive screws to the
correct torque. Always rotate the left captive screw one turn clockwise and then
rotate the right captive screw one turn clockwise. This assures that a uniform and
even torque is applied to the CPU module.
