a module.

Check if the power supply units are providing power to the chassis components. See the
“Troubleshooting the Fan Trays” section on page 8-2
Step 3
Make sure that the I/O module is properly seated in the chassis by following these steps:
a.
Loosen the captive screws on the I/O module until they are no longer in the chassis.
b.
Press the eject buttons on either end of the module.
c.
Simultaneously rotate out both ejector levers until the module is unseated from the midplane.
d.
Place one hand on the module handle and pull the module part way out of the chassis.
e.
Push the module back into the chassis until it is seated on the midplane.
f.
Simultaneously rotate both ejector levers to the front of the module to fully seat the module.
g.
Make sure that each of the captive screws on the module is aligned with its holes in the chassis.
h.
Securely tighten each captive screw (to 8 in-lb [0.9 N·m]) to the chassis.
