Removing the I/O expansion module
To remove the I/O expansion module from the chassis, you must perform a
specific sequence of steps.
Procedure
1. If you are not already grounded, properly ground yourself.
2. Unplug the system cables from the I/O expansion module, as needed, and
keep track of where the cables were connected. Leave the cables in the cable
management arm so that when you install the cable management arm in the
new I/O expansion module, the cables will be organized.
3.
Remove the cable management arms for the left and right sides of the
controller module and set them aside.
4. Loosen the thumbscrew on the cam handle.
5. Pull the cam handle down and slide the I/O expansion module out of the
system, and then place it on an anti-static surface.
6. Remove the side panels from the I/O expansion module by loosening the side
panel thumbscrew and swinging the side panel out of the way.
