Using the Server
The following sections describe how to use this server properly and safely, including an
explanation of the server power on/off sequences, what the POST program checks in
the server, and how to perform a forced power shutdown.
When using the server the following precautions should be observed:
■
Make sure you power off the server before connecting or disconnecting cables
between the server and peripheral devices. Connecting or disconnecting the cables
while the server is powered on may cause malfunction or failures within the server.
■
Verify that the access lamp on the diskette drive is unlit before turning off the
server or ejecting the floppy disk. Turning off the server or ejecting the floppy disk
while the access lamp is lit may damage data being stored on the floppy disk.
■
After turning off the server, wait at least 30 seconds before turning it on again.
Cycling the power immediately may cause malfunction or failures of the server.
■
Before relocating the server, turn off the power and unplug the power cord from
the outlet. Moving the server when it is powered may cause malfunction or failures
of the server.
■
Clean the server regularly. Regular cleaning prevents failures of the server 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 server. A non-qualified option may be mounted
or connected to the server, but it may fail to operate normally or even cause fail-
ures. These types of failures are not covered under warranty.
