1. 1 Introduction
UPCC
1. 1. 2 Hardware Components (Sheet 1 of 2)
UPCC
base
system hardware includes
a WLOC board, which enables a
PC
280/380
to
connect
to
a VS system
via
a
928
link.
The
PC280, PC380,
PC
AT,
or
AT-compatible
computer
possesses functionality similar
to
a
data
link
processor
when
the
UPCC
is
installed.
A Remote Initial Program
Load
[RIPL)
board
is
available
as
a
UPCC
option (1).
The
RIPL
board allows a VS
system connected
to
the
UPCC
to
remotely
IPL
the
UPCC
if the commu-
nications
link
between the VS
and
the
non-Wang
system
fails.
The
RIPL
board is also designed
to
simulate a
system keyboard
and
pass
UPCC
boot
PROM diagnostics, eliminating
the
need
for
connecting a keyboard
to
the
UPCC
system unit.

The
Wang-supplied
RIPL
internal
power cables permit connection
to
the
power connector of a PC280, PC380,
PC
AT,
or AT-compatible computer.
The RIPL
power
cables
are
not
designed
to
fit
any
other systems.
