• 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.
The following common subchannels are associated with console communications on all
other MIPS/IRIX systems:
• Subchannel 0 specifies CPU A.
• Subchannel 1 specifies CPU B.
• Subchannel 2 specifies CPU C.
• Subchannel 3 specifies CPU D.
• Subchannel 4 is the console subchannel.
To select a subchannel as the current subchannel, for a specific node/CPU, perform the
following:
L2> select sub 0a
or
L2> select sub 0c
or
L2> select sub 2a
