Note – You can only access the sc> prompt and view POST messages from either
the serial management port or the network management port.
Note – There are many other OpenBoot configuration variables. Although these
variables do not affect which hardware device is used to access the system console,
some of them affect which diagnostic tests the system runs and which messages the
system displays at its console. For details, see "Controlling POST Diagnostics" on
page 13.
b. To cause the changes to take effect, power off the system. Type:
ok
The system permanently stores the parameter changes and powers off.
Note – You can also power off the system using the front panel Power button.
c. Connect the null modem serial cable to the ttyb port on the Sun Fire V440
server.
If required, use the DB-9 or DB-25 cable adapter supplied with the server.
d. Power on the system.
See the Sun Fire V440 Server Administration Guide for power-on procedures.
