Can't have the GRUB menu for solaris x86 installation

Dears,

I'm trying to install solaris x86 on sun x4170 M2 I started connecting consol to the machine but when I do the reset /SYS command nothing changed
I can see that the /SYS is powered on but I can get the GRUB menu to start the installation of the solaris.

the solaris DVD is already pluged in the machine DVD?

how are you connected to the console output? have you changed the boot order to dvd?

It is unclear from your post exactly what problem you are having.

I suspect that you have not access to the console.

Have you issued an "start /SP/console" to access the serial console?
