The thermal printer
is
an optional module. Other hardware options include displays
and
mass
storage devices.
One
of three displays can be selected, and flexible disc
and
fixed disc storage
devices are available. Various combinations of
CPU, lOP, and
RAM
memory boards can configure
the processor stack. Also, several types of
HP-IO cards are available for various interfacing require-
ments. Refer to Appendix A for additional information on options.
The
HP-IO cards and mass storage controller cards are accessible from the right side of the
computer, and the processor stack cards from the left side. The computer rests on three rubber feet
at the front and two platen-like rollers at the rear. Thus,
it
can easily be moved for service
accessibility by lifting slightly at the front and rolling forward or backward.
CAUTION
THE WINCHESTER FIXED DISC DRIVE CAN
BE
DAMAGED WHEN
SUBJECTED
TO
A SHOCK OF lOG OPERATING OR 20G NON-
OPERATING. TO PREVENT
DAMAGE, LOWER COMPUTER GENT-
L
Y AFTER MOVING IT ON ITS ROLLERS.
Three dc box fans provide cooling
for
the computer. The fans draw the air through a
grill
under the
keyboard
and
exhaust the air out the back of the computer. One fan
is
integral to the processor
stack. The other fans are mounted to the chassis,
one
in
the power supply area
and
one
in
the I/O
card cage area. The 1/0 card cage fan operates at constant speed. The other two fans are variable,
increasing
in
speed as the temperature increases. The computer shuts down
if
the temperature rises
to
100°C
in
the stack or to 97°C
in
the power supply.
