Problems install Aix 5.3

Hello

I have a server that I want to install Aix 5.3, first I change on the sms to install device from the cdrom, when I boot the server on the display hangs up on the message E443 and nothing happens.

Who Can I resolve this.

Thanks in advance for your comments.

if it's an older machine like H70, M80 ... you have to update microcodes to the latest level in order to get AIX 5.3 running

Thanks for answer funksen

yes I know that I have to update the microcode, but this server hasn�t have any o.s.

I turn on and get in on the sms but I cant find to know what microcode has this server.

Then I try to install the aix 5.3 and boot from install device and when reboot appears the message E443.

and know I dont see nothing (the sms) nothing

My question its

What can I do to see again the sms ? and how can I know the microcode of the server ? and how install the new microcode if this server dont have any os?

Thanks really really much

What type of system is it?
If it has a service processor you can connect a terminal to the serial port and pressing any key will bring up the service processor menu.
This should show the firmware level.
This will also allow you to update the firmware from the floppy drive.

Check here for the firmware latest level and update proceedure:

If it is a 91xx machine type (p5xx - any level of firmware should support AIX 5.3) the hardware support docs are here:

Search in the left search box for what you are after.

If it is a pre power5 machine (machine type p6xx or 70xx) try here:
