Removing The System Dimms - IBM N6270 Hardware And Service Manual

Procedure
1. If you are not already grounded, properly ground yourself.
2. Unplug the system cables and SFPs from the controller module, as needed, and
keep track of where the cables were connected. Leave the cables in the cable
management arm, so that when you reinstall the cable management arm in the
controller module, the cables will be organized.
3. Disconnect the right and left cable management arms from the controller
module. To release the arms, press the silver button on the power supply side
of each arm, and then remove the arm from the controller module.
4. Loosen the thumbscrew on the cam handle.
5. Pull the cam handle downward and slide the controller module out of the
system.
