Console Strategy

The firmware starts a console-selection sequence at system boot time if any of following are true:

Ÿ A console has not yet been selected

Ÿ A previous console-selection sequence timed-out

ŸA change in the system configuration has affected the console (keyboard

installed/removed,

mouse installed/removed,

graphics

adapter

installed/removed

or moved to another PCI slot).

 

 

 

The console-selection

sequence allows you to

select

(from the

appropriate input

device) any one of the available console devices. If no console is selected wit approximately 60 seconds, serial port 1 (S1) is selected as the console and the selection sequence times-out.

Attention : If an ASCII terminal is attached to serial port 1 (S1), and there is interaction with this terminal:

Ÿ AfterOK displays in the operator panel

AND

ŸBefore the power-up sequence is initiated

the firmware will still use this terminal as the console, regardless of the previ console selection.

After

a

console

has

been selected, the

console-selection

sequence

is

only

starte

boot

 

time

if

there

is a change in the system configuration (as

described abo

the

contents

of

the

system's

nonvolatile

memory

(NVRAM)

are

lost.

 

 

 

Note:

 

Moving

an

ASCII terminal

from one serial port to another

(from

S1

to

S2)

cannot

be

detected

by

the

firmware,

so

it

does

not constitute

a

configuration

You

can

also

initiate

a

system console-selection sequence

from

the

SMS

menus.
