Introduction
This technical manual describes all the activities required to modify your PCE
hardware (e.g. installing boards or drives).
Modifications to the system unit very often require the system to be reconfigured
afterwards with the setup menu or the EISA configuration utility. Please read the
notes on this subject in the text. If certain system settings can be made using either
the setup menu or the EISA configuration utility, you should use the latter.
Some system extensions are supplied together with a floppy disk containing data
for the right board configuration. In such a case you must update your backup copy
of the Configuration Utility Disk (System Configuration Disk) before you install the
system expansion. Please read the section "Copy/update CFG. files" in the User
Guide of the EISA Configuration Utility.

Safety
!Please note the information provided in the Operating Manual of the PCE.
Read these notes carefully and follow the instructions when you open your
PCE.
– The power switch does not disconnect the device from the line voltage. To do
this, you must pull out the power plug.
– Before opening the unit, first switch it off and then disconnect the power plug.
– No data transmission cable should be connected or disconnected during a
thunderstorm.
– Only qualified technicians may repair the device. Unauthorized opening or
incorrect repair may greatly endanger the user (electric shock, fire risk).
– Correct operation of the PC in accordance with IEC 950/EN60950 (cooling,
protection against fire, RFI suppression) is guaranteed only if the housing is
closed. Also put back the back cover for the slots.
– Install only system expansions that satisfy the requirements and rules governing
safety and electromagnetic compatibility and relating to telecommunications
terminal equipment. If you install other expansions, you may damage the
system or violate the safety regulations and regulations governing RFI
suppression. Information on which system expansions are suitable can be
obtained from the customer service or your sales office.
– The power supply unit (marked with a lightening flash symbol) should be
removed and replaced only by authorized specialists.
– If your PCE is equipped with a power outage fallback facility, the battery block
should be removed and replaced only by authorized specialists.
– Due to the danger of injury or electric shock, do not remove the rear part of the
casing.
– The warranty expires if the PCE is damaged during the installation or
replacement of system expansions.
A26361-K326-Z124-1-7619 3
Safety
!The real-time clock chip on the system board includes a lithium battery
which may be replaced only by authorized personnel. Incorrect handling
may lead to a risk of explosion.
The chip may be replaced only with an identical chip or with a type
recommended by the manufacturer.
The chip must be disposed of in accordance with local regulations
concerning special waste.
Modules with ESDs (electrostatic sensitive devices) may be identified by the
following label.
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 with modules containing ESDs.
– The equipment and tools you use must be free of static charges.
– 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.

Disk Array Controller System unit
Cabling of SCSI controller boards
If the internal or external hard disk drives are not driven by the SCSI controllers
integrated on the system board but by a separate SCSI controller (standard SCSI
controller or Disk Array Controller), the following are changed: the cabling of the
hard disk drives, the allocation of the SCSI-ID and the position of the terminating
resistors. The following graphics show the three possible usages.

System unit Installing and removing memory modules
Installing and removing memory modules
In its basic configuration, the main memory has a capacity of 16 or 32 Mbytes and
can be expanded to 512 Mbytes by using 32-Mbyte-modules.
1
1 = memory bank
The memory board has 16 sockets for memory modules (SIMM - Single In-line
Memory Modules / PS/2 modules) which are divided into 8 memory banks with 2
sockets each. Memory modules have a capacity of either 8 or 32 Mbytes. A
memory bank must always be fully occupied and equipped with memory modules
of the same capacity. Thus, a memory capacity of 16 or 64 Mbytes is possible for
each memory bank, which permits a maximum memory expansion of 512 Mbytes.
The size of the memory modules may vary between memory banks. The 8 memory
banks can be equipped in any order. There may thus be unequipped memory
banks between equipped banks.

When installing memory modules make sure that the memory modules already
installed do not hinder the installation of subsequent modules.
Insert the first memory module into its slot from the back at an angle of about
45˚.
Tilt the module carefully to the front until it snaps into place and is in a vertical
position in the socket.
Check that the memory module is securely in place in its socket.
The notches on the fastening clips must snap securely into place into the holes
on the memory module.
Repeat these steps for installing the second and each additional memory
module in its appropriate socket.

Installing and removing disk drives System unit
Installing and removing disk drives
In the system unit of the PCE, there is room for a total of ten drives.
All bays are of drawer design, thus simplifying installation and removal of the
drives. The top four bays (1 - 4) are intended for four accessible drives of half
height (slimline), either in 3 1/2" or 5 1/4" format. Instead of two half-height drives,
one full-height drive can be installed. The lower six bays (5 - 10) are intended for
non-accessible 3 1/2" SCSI drives.
When installing a SCSI drive (e.g. hard disk, streamer or CD ROM drive), first read
the documentation which comes with your SCSI drive.
An address (identification number or ID) must be set for each SCSI drive.
As standard, the terminating resistor is plugged in at the hard disk installed in the
lowest bay (ID=0).
!The address of the installed hard disk (ID=0) must not be modified since the
system BIOS requires this address for booting the system.
Installing an accessible drive
!SCSI drives in bays 1 - 4 may not have terminating resistors.
Open the system unit as described under "Opening the system unit".
Select an installation position appropriate for the drive (half-height, full-height).
A26361-K326-Z124-1-7619 29
System unit Installing and removing disk drives
Unscrew the mounting screws on the drawer containing the bay in question and
remove the associated metal plates.
Pull the drawer out of the system unit.
For each drive in bays 1 to 4, you require an adapter for connection to the system.
Floppy disk drives and SCSI drives require different adapters. A suitable adapter is
supplied with each drive.
30 A26361-K326-Z124-1-7619

Installing and removing disk drives System unit
Screw the adapter to the rear of the drawer as shown. Ensure that the adapter
is screwed in the right way round. The cables must always be on top, the
connector for the connection board at the bottom.
The drive is either installed as a "visible" or "concealed" drive. Installation depends
on whether the drive should be accessible from the outside (e.g. floppy disk drive,
CD-ROM) or not (hard disk).
Place the drive in the drawer.
Screw down the drive in accordance with the type of installation.
A26361-K326-Z124-1-7619 31
System unit Installing and removing disk drives
Connect the data cable to the drive. Ensure that the connector is plugged in the
right way round (coding).
Plug the power supply connector into the drive.
Slide the drawer into the system unit.
Attach the drawer and, if you have installed a drive to be concealed (non-
accessible), also screw down the metal plates previously removed.
