How to Clear the CMOS and Reset the BIOS Password Using Jumpers

You can reset a password and clear both the CMOS NVRAM and BIOS password by changing the J42_1 (compute node 0) and J42_2 (compute node 1) jumper positions.


Note - The Sun Blade X6275 M2 Server module is a dual-node server. If necessary, use this procedure for both nodes.


  1. Prepare the server module for service. See Preparing the Server for Service.
  2. Locate the jumpers J42_1 (compute node 0) and J42_2 (compute node 1) jumpers on the rear of the motherboard. The jumper default position is 1-2.

  3. Place the jumper on position 2-3 for 10 seconds.

    This action clears the CMOS and resets the BIOS password.

  4. Remove the jumper from position 2-3, and replace it back to its original position 1-2.
  5. Prepare the server module for operation. See Preparing the Server for Operation.
