Removal

5. If necessary, remove several PCI and EISA options from the bottom of the PCI
card cage up until you can access the server control module.
6. Disconnect the two cables connected to the PCI motherboard at the server
control module end.
7. Disconnect the twisted pair power cable from the module.
8. Place a credit car or a piece of cardboard between the edge of the SCM module
and the B3050 module to protect the delicate pins of the ASICs located in the
lower right corner of the B3050 module.
9. The server control module is held in place by four stud snaps. Using a flathead
screwdriver gently pry the SCM module off the snaps and remove it. Make sure
