Disabling a Forgotten Password
The blade's software security features include a system password and a setup password, which are discussed in detail in Using the System Setup Program. The password jumper enables these password features or disables them and clears any password(s) currently in use.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
If you are changing the jumper setting on a PowerEdge M905 or M805
blade, remove the system board to gain access to the jumpers. See
Removing the System Board.
Relocate the jumper plug to disable the password feature.
See Figure 7-1 (PowerEdge M905), Figure 7-2 (PowerEdge M805), Figure 7-3 (PowerEdge M600), or Figure 7-4 (PowerEdge M605) to locate the password jumper on the blade board.
If you are changing the jumper setting on a PowerEdge M905 or M805
blade, reinstall the system board. See Installing the System Board.
When the blade is on, the power-on indicator is solid green. Allow the blade to finish booting.
The existing passwords are not disabled (erased) until the system boots with the password removed. However, before you assign a new system and/or setup password, you must reinstall the password jumper.
NOTE: If you assign a new system and/or setup password with the jumper removed, the system disables the new password(s) the next time it boots.
If you are changing the jumper setting on a PowerEdge M905 or M805
blade, remove the system board to gain access to the jumpers. See
Removing the System Board.
Relocate the jumper plug to enable the password feature.
If you are changing the jumper setting on a PowerEdge M905 or M805
blade, reinstall the system board. See Installing the System Board.
