LinuxQuestions.org - Sun Blade 2500 keeps rebooting continuously

Hello,

I have a Sundance server who due to some power outage keeps rebooting continuously.
I managed to connect with a console cable with Tera Term.
When the server starts up i see these messages:

rebooting...

Sun Blade 2500, No Keyboard
Copyright 1998-2003 Sun Microsystems, Inc. All rights reserved.
OpenBoot 4.13.5, 2048 MB memory installed, Serial #58217565.
Ethernet address 0:3:ba:78:54:5d, Host ID: 8378545d.

Rebooting with command: boot
Boot device: rootdisk File and args:
/

and after that the server reboots and starts over again, in a loop.

I managed to enter to OpenBoot ok Prompt but besides some show commands i couldn't do much else.

If i try to enter to boot -s i get an error message response "Fast Data Access MMU Miss"

The problem is that i don't have the CD/DVD anymore... the server is very old.

Can someone please help with a suggestion?

Best regards,
