Function
Lighted when unit power is shut down
due
to
abnormal
operational
condition.
When in
up
or middle position,
enables
power-on
control in
the
unit
power supply. (Middle position
inhibits
the
unit
reset
signal.)
When in down position, power
to
unit
is off.
Selects
the
processor bus
to
which
the
processor
cluster
is
to
be
connected
(up
is
processor bus A, down is
B).
SeleGts
the
clock
source (up, A or down,
B)
for
the
unit
clock
subsystem.
Establishes
the
logical address of
the
cluster
within
a group
of
processor clusters.
Note:
The
5-bit
chassis
location
number
and
not
the
proce'ssor
address is used in addressing
the
configuration
switches for
a
given
unit by
the
RD
instruction
directed
to
the
Con-
figuration
Control Panel.
When in down
position,
inhibits
the
BP
from
operating
on
the
internal bus.
When in down position, inhibits
the
MIOP from operating on
the
internal bus.
When in down position, inhibits
external
010
interface.
Selects
either
the
remote
console
(down position) or
alternate
operator's
console
(up position)
to
enter
data
on
the
Remote
Channel
Interface.
Selects
communications frequency for
the
primary
operator's
console
as
follows:
up
= same frequency as remote
channel
down = 1200 baud
Note:
The 1200 baud
selection
is
effective
only if
the
REMOTE
CHANNEL switch on
the
System Control Panel
is
not in
the
SCC posi ti on.
Selects
communications frequency for
the
alternate
