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).
Selects the clock source (up, A or down, B) for the unit clock
subsystem.
Establishes the logical address of the cluster within a group of
proc essor clusters.
Note: The 5-bit chassis location number and not the processor
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
i nterna
I
bus.
When in down position, inhibits external DIO interface.
Selects either the remote console (down position) or alternate
operator1s console (up position) to enter data on the Remote
Channel Interface.
Selects communications frequency for the primary operator1s
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 operator1s
console and the Remote Diagnostic Interface (Remote Channel) as
follows:
