Removing the Top Panel
To remove the top panel (reference Figure 5-1):
_________________________ Caution ___________________________
Make sure the system unit On/Off switch is in the "off" position before you
remove the system top and side panels.

Shut down the operating system following the instructions in the operating system
documentation.
2.
Set the On/Off switches on all external options connected to the system to the off
position.

discharge safely.
