InfoDoc #:209731 How to Reset ILOM on Sun T5120/T5220/T5140/T5240/T5440 - Simplified

InfoDoc #: 209731 (simplified, paraphrased, with photos)
  • Power down the system using the front panel power button
    • If a SP admin account exists, you can use that account's ALOM Command Line Interface poweroff command
  • Unplug the power cable(s) and remove the top cover
  • Place a jumper between Pins 1 & 2 of header PJ6801 (photo coming soon)
    • This Jumper is located at the rear of the T5120/T5220 motherboard
  • Place a jumper between pins 1 & 2 of header J10401 (photo coming soon)
    • This header is located on the SP of the T5140/T5240, near the center, rear edge of the motherboard
  • Replace the top cover and plug in the power cable(s)
  • Press the front panel Power button to power on the system
    • You must power on the system to complete the reset because the state of the PJ6801 jumper cannot be determined unless the host CPU is running
  • The SP root password should now be reset to the default 'changeme'
  • Log in as root into the SP
    • ssh root@ip.add.re.ss (address may be obtained by monitoring the dhcp lease db)
    • web browser via network management port
    • tip/cu - hardware or terminal server via serial management port (Cisco RJ45 -> DB9)
  • Power down the system using the front panel power button
  • Unplug the power cable(s) and remove the top cover
  • Remove the jumper on header PJ6801
    • The jumper on PJ6801 must be removed after a password reset or the password will be reset upon each time the system is powered up
  • Replace the top cover and plug in the power cable(s)
  • The SP's root account password can be changed using the usual SP's root account's command line user interface command.

    Hi,
    Trying to reset a T5120 too, followed your guide, with no luck.
    The Ilom doesn't show up on dhcp.
    Any help ?
    I don't have the DB9 cable

      Alternatively, try doing #ssh root@localhost
      passwordd is "changeme" with no quotes

      Also, instead of a db9 cable, use a usb to rj45 adapter cable and connect that to the serial management console (rj45). You need to use a terminal emulator with the following settings: 9600 baud 8n1 (putty will suffice)
