WARNING:
Unplug the power cord before dis-
assembling the system unit. Voltage is present
inside the system unit even after the power
switch is turned off. All voltage is removed only
when the power cord is unplugged.
If a fault occurs after completing the option installation, verify that the installation was per-
formed correctly. One beep indicates that the computer has completed its power-on self-
test. If intermittent beeping occurs or the option is not operating properly, turn off the com-
puter and try again. If the problem persists, see “Troubleshooting” in Section 4.
