Front Control Panel. You may have to hold the Power button down for
several seconds.

the server.
3. Pull the server out of the rack as far as possible to gain access to the rear
part of the top cover.
WARNING Make sure that the rack is anchored securely, so it will not tip
when the server is extended on the rails.
Use a screwdriver tip to push in the lock tabs on the rack
slides to prevent pinching your fingers.

open the rear access panel.

described in the Chapter 8 section, “Removing the Legacy I/O Board”.

block J7A1, see Figure A-14.

Chapter 8 section, “Installing the Legacy I/O Board”.
