8: System Control
Console Selection
The brick with which the L1 controller communicates in console mode is the system
console or global master, and you can view and set it with the
select
command. By
default, the Cx-brick attempts to communicate with its local CPUs when console mode
is entered. If the system has been powered on and one of the bricks receives a request to
be the system console, then the Cx-brick attempts to communicate with that brick. The
select
command by itself shows the current console mode settings:
001c07-L1> select
console input: 001c07 console0
console output: not filtered.
The following common subchannels are associated with console communications:
•
Subchannel 0A specifies Node 0, CPU A.
•
Subchannel 0B specifies Node 0, CPU B.
•
Subchannel 0C specifies Node 0, CPU C.
•
Subchannel 0D specifies Node 0, CPU D.
•
Subchannel 1A specifies Node 1, CPU A.
•
Subchannel 1B specifies Node 1, CPU B.
•
Subchannel 1C specifies Node 1, CPU C.
•
Subchannel 1D specifies Node 1, CPU D.
•
Subchannel 2A specifies Node 2, CPU A.
•
Subchannel 2B specifies Node 2, CPU B.
•
Subchannel 2C specifies Node 2, CPU C.
•
Subchannel 2D specifies Node 2, CPU D.
•
Subchannel 3A specifies Node 3, CPU A.
•
Subchannel 3B specifies Node 3, CPU B.
•
Subchannel 3C specifies Node 3, CPU C.
•
Subchannel 3D specifies Node 3, CPU D.
•
Node 0 console subchannel.
•
Node 1 console subchannel.
•
Node 2 console subchannel.
•
Node 3 console subchannel.
