On-board Serial Interface

Each System Board has one on-board serial interface port (RS-232C).
Each partition uses a serial interface port for the console path. Use the System Board's RS-232C
port which is connected to the system volume as the console port. The console port can be set
from the OBP environment variables (tty-conspath, tty-sub-conspath). If these values are not set
manually, the slot port of the lowest slot number among the System Boards which construct the
partition is allocated. If the port set to tty-conspath does not exist when starting up the partition,
the port set to tty-sub-conspath is allocated; and if both of them do not exist, the same setting
there is not any value set is applied.
The on-board serial interface is used only for the console path. To connect peripheral devices
using a serial interface, use serial interface PCI cards.

Console Connection Unit

This section describes how to connect SMC and the Console Connection Unit.
To use the console function for the partitions, connect the RS-232C port of the System Board
with the SMC through the Console Connection Unit. The Console Connection Unit and the
SMC can be connected through the System Control LAN. The user has to prepare additional
Console Connection Units and RS-232C cabling according to the specific requirements of the
number of partitions and method of interconnection.
