5. Set the controller module aside in a safe place and keep track of which chassis slot it came from, so that it
can be installed into the same slot in the replacement chassis..
6. Repeat these steps if you have another controller module in the chassis.
Step 4: Remove the I/O modules
To remove I/O modules from the impaired chassis, including the NVRAM modules, follow the specific
sequence of steps.
1. If you are not already grounded, properly ground yourself.
2. Unplug any cabling associated with the target I/O module.
Make sure that you label the cables so that you know where they came from.
3. Remove the target I/O module from the chassis:
a. Depress the lettered and numbered cam locking button.
The cam locking button moves away from the chassis.
b. Rotate the cam latch down until it is in a horizontal position.
The I/O module disengages from the chassis and moves about 1/2 inch out of the I/O slot.
c. Remove the I/O module from the chassis by pulling on the pull tabs on the sides of the module face.
Make sure that you keep track of which slot the I/O module was in.
