communication channel.
8.12 Serial Line Selection
All payload serial interfaces (COM #0 of PP #0, PP #1, SP) of the ATCA-9405 can be redirected
to the terminal server. It is even possible to redirect two serial interfaces to the terminal server
in parallel. Thus it is possible to have one terminal server specific channel configured to redirect
the SP serial interface and the second channel configured to redirect either the serial interface
of the first octeon, or of the second one. It is not possible to have both serial interfaces of the
octeon redirected to the terminal server.
Note that the serial instance 0 of the terminal server is reserved for the serial interface of the SP
and instance 1 for either PP #0 or PP #1.
There are three connectors at the front panel. One connector (serial instance 0) is used to share
the serial interface of the SP and the IPMC and the other two (serial instance 1 and 2) are used
to connect to the serial interfaces of the cavium cpus.
In addition, there is a serial connector at the RTM. Either the serial interface of the first octeon
or the serial interface of the second octeon is redirected to this interface.
