How to Reset ILOM password on a Sun x4200 Server
Posted by on May 15, 2010
Power down and disconnect the server, open up the server, place a jumper over Jumper P4 (different models like the M2 use different ports) but P4 is on a block of 3 2-pin jumpers on the right-hand side near the power supplies.
Power up the server and wait for the OS to boot (important), login via the serial console connection; the user/password will now be root/changeme
Reset the password via the web GUI and power down the server
remove the jumper and it will work using the password you set; if you forget to remove the jumper it will always default the password to changeme
As a bonus you can change the IP address via the serial console whilst it’s defaulted
login using root/changeme
cd /SYS/network
show (will display the current config)
set pendingipaddress=1.1.1.1 (or whatever you need)
set pendingipgateway=1.1.1.1 (or whatever you need)
set commitpending=true
and after a minute or so the IP address will be set and should be accessible over the network
The full service manual is online here
Don’t forget to remove the P4 jumper, if you can’t find a jumper as they are quite rare these days – look for an old HP or Compaq server, that’s what I did 🙂

Danke für den Blogpost, mal sehen, ob ich damit mein Problem gelöst bekomme.
Hi,
What is the best way to gracefully shutdown/power-off the X4200 server?
Thanks,
Emil
Hi Emil, sorry for the delay – not too familiar with the x4200 other than some brief work that led to this post; anyone else?
