Console Selection
When in console mode, the L2 communicates with the IRU set with the select command to be
the system console or global master. All input from the console is directed to that IRU. You can
set and view the system console with the select command.
The L2 chooses an IRU as the default console in the following order of priority:
• The IRU in the lowest numbered rack and slot, which has previously produced console
output.
• The IRU in the lowest numbered rack and slot.
The select command by itself shows the current console mode settings:

The following are ten common subchannels associated with console communications:
• Subchannel 0A specifies Blade 0, CPU A.
• Subchannel 0C specifies Blade 0 CPU C.
• Subchannel 1A specifies Blade 1, CPU A.
• Subchannel 1C specifies Blade 1, CPU C.
• Subchannel 2A specifies Blade 2, CPU A.
• Subchannel 2C specifies Blade 2, CPU C.
• Subchannel 3A specifies Blade 3, CPU A.
