Note that an interrupt cannot be used by two ISA boards or onboard
controllers at the same time.
The monitor controller of the system board does not require interrupt
IRQ9. If you are using a different monitor controller, it may need
interrupt IRQ9.

Important Notes
!
Be sure to read this
p
a
g
e carefull
y
and note the information before
y
ou
open the system.
Please note the information
p
rovided in the cha
p
ter "Safet
y
"inthe
Operating Manual of the system.
Incorrect replacement of the lithium battery may lead to a risk of
explosion. It is therefore essential to observe the instructions in the
section „Extensions on the system board“-„Replacing the lithium
battery“.
The lithium batter
y
must be re
p
laced with an identical batter
y
or a batter
y
type recommended by the manufacturer (CR2032).
Do not throw lithium batteries into the trashcan. Your vendor or dealer or
their authorized re
p
resentatives will take used batteries back free of
charge so that they can be recycled or disposed of in the proper manner.

Important Notes
8A26361-D970-Z120-3-7619
Connecting cable for peripherals must be adequately insulated to avoid
interference.
Modules with electrostatic sensitive devices (ESD) may be identified by labels.
When you handle modules fitted with ESDs, you must observe the following
points under all circumstances:
• You must always discharge yourself (e.g. by touching a grounded object)
before working.
• Theequipmentandtoolsyouusemustbefreeofstaticcharges.
• Pull out the power plug before inserting or pulling out modules containing
ESDs.
• Always hold modules with ESDs by their edges.
• Never touch pins or conductors on modules fitted with ESDs.

Settings in BIOS Setup
In BIOS Setup you can set the system functions and the hardware configuration of
the system. In addition, the BIOS Setup displays technical information on the
system configuration.
When it is supplied, the system is set to factory default settings. You can change
these settings in BIOS Setup. Any changes you make take effect as soon as you save
the settings and quit the BIOS Setup.
The Operating Manual describes how to call the BIOS Setup and change menu
entries.
You can select the following settings in the BIOS Setup:
Main - system functions
Advanced - advanced system configuration
Security - security features
Server - Server management features
