Preface
THE PRODUCT The new ND—SOOO ES Model
C replaces the
current
ND-SOOO
Oonpacts. It covers
the low/medium
end
of the ND-SOOO systems and is meant
to be used
as general departemental systems and
servers
for
installations that are not too
large.
THE MANUEL This manual covers the ND-SOOO ES Nbdel C. It is
meant to be a helping hand for the service
staff.
The manual
is a
physical description and
does
NOT cover the handling of system errors, test

Chapter 1 INTRODUCTION
This chapter gives an introduction to the
ND-SOOO
ES C models.
1.1 System description
The new
ND—SOOO ES Model
C replaces the
current
ND-SOOO Compact. It covers the low/medium end
of
theND—SOOO systemsandismeanttobeusedas
general departmental
systems and servers for
installations that
are not too large.
It has the same cabinet
as the previous version,
except for
the front cover. The interior,
however, is completely
new. It consists of
a
large card crate, into
which all cards and
devices (including
the new power supply, the fan
unit, disks, floppy units and streamer units)
can be plugged. The backwiring
is located in the
middle of the card crate, and cards
and devices
are plugged in from both the front
and the rear
sides.
The new ND-SOOO
ES Nbdel C is available
with
all
ND-SOOO
CPU versions, including
NIB-5800.

1.3 Upgrading possibilities
Full upgrading
is possible between
the ND-SOOO
ES Nbdel C systems:
0 Upgrading between
models, for example
upgrading an ND—SZOO
Model C1 to an ND-SZOO
Model C5.
'
o Upgrading
between systems, for
example
upgrading an NIB-5200
to an MID—5700.
Note that extra memory boards
are not included
in the upgrading kits, and
must therefore
be
ordered separately.

It is easy to replace defective devices and
nodules, as the parts that normally need service
are
plugged
directly
into the backwiring
and
the
cabinet is practically free from internal
cables.

Fan tray
The cooling
is based on the
same principle
as
the
previous ND-SOOO
Ccmpact. The fans are
located in a
fan tray plugable from the
bottom
of the
front into the backwiring
(see figure 4).
The
fans are the DC type,
with an extra wire for
indicating
the rotation
speed. The power
for the
fans is supplied
by the DC 500 power supply, and
the voltage is controlled
by software and the
ambient temperature.
The input to the fan speed
control canes
from an NTC resistor
which
senses
the roan temperature.
This sensor is mounted at
the
top of the backwiring,
close to the air
inlet.
NOTE
Note that you
must turn the power
off
before removing or inserting
the fan
tray.
2.1.3 Operator panel
The operator panel and key switch are located at
the top of the
front (see figure
4). It is
similar
to the
operator panels on
previous ND
computers, but the
display
has been removed. The
information
that earlier could be read frcm the
display is still available,
but you must connect
a maintenance display
to get it (see
page 42).
The operator
panel
is connected
to the
backwirihg via a flat
cable along the top of the
cabinet.

The backwiring acts as the main
connection
between all internal modules.
All cards
and
devices are plugged directly
into the
backwiring,
including the
power
supply
and the
fan
tray.
The
backwiring also contains:
0 Temperature
sensor
(regulating
the fan
Speed)
0 Connector
for the operator panel
0
An
area
where it is possible to
measure the
voltages
o Terminator/strap fields
for
the SCSI
bus
0 Switches for splitting the SCSI bus
The backwiring is prepared for
taking
care of
the internal SCSI bus. This bus has been routed
to all internal SCSI devices, and
it
ends up on
the plugboard in position 14. Here the bus can
be terminated, or one external single- ended
SCSI device can
be connected.
This
could, for
example,
be a
magtape unit used for backup.
bkmmally
all devices on the SCSI bus
can be
accessed from ND-lOO,
but the strap/terminator
fields and
the split switches on the backwiring
make it possible to split
the SCSI bus. See the
description in the
section "SCSI bus"
on page
14.
Two
different versions
of the backwiring are
used:
0 PCB number 5812 for early versions
0 PCB number 5816 for later versions
The difference
between these two backwirings is
the possibility to split the bus with
