Using the System
The following sections describe how to use this system properly and safely, including
an explanation of the system power on/off sequences, what the POST program checks
in the system, and how to perform a forced power shutdown.
When using the system the following precautions should be observed:
■ Make sure you power off the system before connecting or disconnecting cables
between the system and peripheral devices. Connecting or disconnecting the cables
while the system is powered on may cause malfunction or failures within the
system.
■ Verify that the access lamp on the diskette drive is unlit before turning off the
system or ejecting the floppy disk. Turning off the system or ejecting the floppy
disk while the access lamp is lit may damage data being stored on the floppy disk.
■ After turning off the system, wait at least 10 seconds before turning it on again.
Cycling the power immediately may cause malfunction or failures of the system.
■ Before relocating the system, turn off the power and unplug the power cord from
the outlet. Moving the system when it is powered may cause malfunction or
failures of the system.
■ Clean the system regularly. Regular cleaning prevents failures of the system and its
components.
■ Lightning may cause a momentary voltage drop. To prevent this problem, an
uninterruptible power supply unit is recommended.
■ Only use options qualified for the system. A non-qualified option may be mounted
or connected to the system, but it may fail to operate normally or even cause fail-
ures. These types of failures are not covered under warranty.
