Important notes
Store this manual close to the device. If you pass on the device to third parties, you should also
pass on this manual.
!Be sure to read this page carefully and note the information before you open the Server.
Please note the information provided in the chapter "Safety" in the Operating Manual of
the server.
Incorrect replacement of the lithium battery may lead to a risk of explosion. It is therefore
essential to observe the instructions in the chapter "I/O board" - "Replacing the lithium
battery".
The lithium battery must be replaced with an identical battery or a battery type
recommended by the manufacturer (CR2032).
Do not throw lithium batteries into the trashcan. It must be disposed of in accordance with
local regulations concerning special waste.
Connecting cables for peripherals must be adequately insulated to avoid interference.
!Components can become very hot during operation. Make sure you do not touch
components when making extensions to the boards. There is a danger of burns!
iThe warranty expires if the device is damaged during the installation or replacement of
system expansions. Information on which system expansions you can use is available
from your sales office or the customer service.
Boards with electrostatic sensitive devices (ESD) may be identified by labels.
When you handle boards 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.
• The equipment and tools you use must be free of static charges.
• Pull out the power plug before inserting or pulling out boards containing ESDs.
• Always hold boards with ESDs by their edges.
• Never touch pins or conductors on boards fitted with ESDs.

Write protection for floppy disks - switch 6
Switch 6 is used to define whether floppy disks can be written or deleted in the floppy disk drive. To
write and delete floppy disks, the write -protection in BIOS setup must be disabled (in menu Security,
the field Diskette Write must be set to Enabled).
on The floppy disk drive is write-protected.
off Read, write and delete floppy disks is possible (default setting).
Skipping the password query - switch 7
Switch 7 is used to define whether the password is queried at system startup, if the password
protection is enabled in BIOS Setup (in Security menu , the Password field must be set to Enabled).
on The password query is effective.
off The password query is skipped (default setting).
Recovering System BIOS - switch 8
Switch 8 enables recovery of the old system BIOS after an attempt to update has failed. To restore
the old system BIOS you need a Flash BIOS Diskette (please call our customer service).
on The system boots from the "Flash BIOS floppy disk" from Drive A and reprograms
the system BIOS on the I/O board.
off The system is started with the system BIOS on the I/O board. The system BIOS
cannot be reprogrammed. (Default setting)

Interrupt Request Levels
The following applies to all four PCI buses: All INTA# PCI interrupts of a PCI bus are carried on
various PCI bus interrupts of the PCI interrupt controller (MINT-ASIC or MINT-ASIC plus PIIX4 for
PCI bus 0A). This prevents PC boards in different slots of the same PCI bus from using the same
PCI interrupt.
The VGA controller, the MINT-ASIC, the I960 I2O controller and the PCI-to-PCI bridge do not use
PCI interrupts.
The following tables show the interrupt assignment of the four PCI buses.
PCI-Bus 0-0A
The PCI bus interrupts of the compatible 32 bit PCI bus, PCI bus 1-0A, are carried on both the PIIX4
Southbridge and on the MINT-ASIC.

Four identical memory modules must be installed per memory bank. Partial equipping of a memory
bank is not possible. The equipping sequence of the memory banks is arbitrary.
Each slot has a clear address (e.g. 2B): Here the letter specifies the memory bank to which the slot
belongs, and the number specifies the slot number within the memory bank. 2B therefore
designates slot 2 in memory bank B.
The memory modules must meet the following specifications:
• Socket: DIMM
• Memory type: EDO-DRAM
• Voltage: 3.3 V
• Speed: 50 ns or 60 ns
• Refresh mode: 2k, 4k or 8k
• Memory organization: 4Mx72, 8Mx72, 16Mx72 or 32Mx72
• Memory size: 32 Mbyte, 64 Mbyte, 128 Mbyte or 256 Mbyte
• Memory technology: 16 Mbit or 64 Mbit
Installing memory modules
²
Flip the holders on each side of the relevant location outwards.
²
Insert the memory module in the slot while folding the side holders up until the memory module
engages.
Removing a memory module
²
Flip the holders to the right and left of the location outwards.
²
Pull the memory module out of its location.
