Backplane Compatibility
Some of the existing HP 3000 Series II Computer Systems
are
the
result
of
a
rnodif ication
program
that
upgraded
the earlier
pre-Series II
systems
to
Series II
status.
If your
HP 3000
Series II
computer
is
one
of
these
rnodif ied systems,
it is
necessary to check the backplane in the I/O card cage for c6mpat-
i bi l i ty with the INP.
If the backplane is identified with the HP
part number 30002-60006, it is compatible; so
proceed
with
the
INP
installation.
If, however, your Series II system still has
the earlier backplane, it is necessary to
replace
it
with
the
part no.

before installing the IIJP.
The

by

PCA Jumpers and Switches
The jumpers used on the INP
PCA
boards
have
all
been
preset
during board calibration at the factory, and no field alterations
are required.
There
are,
however,
four
blocks
of
miniature
cocker
switches
(called
"rocker switch packs")
on the INP-MPU
board that must be manually set to configure
the
INP
for
your
specific
system
and application.
Figure 2-1 shows the location
of these switches.
Two sets of these rocker switch packs are used
to
manually
set
the
HUX
service
requests (SRO through SR15).
Another block of
switches is used to set the DRT number in
octal
notation.
The
Eourth
block of switches selects the functions outlined in table
2-3.
I
Set the switches as follows before installing the PCA
boards
in
the computer card cage.
a.
The MUX service request switches are the
two
rocker
switch
packs
located on the INP-MPU board (part no. 30010-60001) in
columns 12 and 13, at row 7, as shown in
figure
2-1.
Each
rocker
switch
pack consists of eight miniature two-position
switches in a block.
Doth sets of switches are labeled
with
numbers l through 8, and the OPEN position is also labeled on
the switch block.
To set the MUX service request, close only
one of the 16 rocker switches while leaving the others in the
OPEN position.
Service requests SRO through SR7 are set into
the switch block on the right (column
13,
row
7)
and
SR8
through
SR15
are
set
into
the
switch
block on the left
(column 12, row 7) as listed in table 2-1.
