Console Selection

007-4653-001
When in console mode, the L2 communicates with the Cx-brick that is the system console
or global master. All input from the console is directed to the Cx-brick. You can set and
view the system console with the select command.
The L2 controller chooses the Cx-brick as the default console in the following priority
order:
• The Cx-brick in the lowest numbered rack and slot, which has produced console
output, and has an attached IX-brick.
• The Cx-brick in the lowest numbered rack and slot, which has an attached IX-brick.
• The Cx-brick in the lowest numbered rack and slot.
The select command by itself shows the current console mode settings:
L2> select

console input: 001c07 CPU 0A
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.
