Disabling a forgotten Management Module password

The software security feature of the system includes a Management Module password. The Management Module password jumper enables or disables Management Module password features and clears any Management Module passwords in use. You must have physical access to the chassis to recover and reset the forgotten password.

Prerequisites

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 are shipped with your product.

Steps

  1. From the chassis, remove both the Management Modules (MM).
  2. Turn the MM over and locate the P57 RESET PASSWORD jumper (marked as PWD_RST on the printed circuit board).

  7. Log out and log in again using the modified password to ensure that the change is successful.
  8. Remove the MM and move the jumper from pins 1 and 2 back to pins 2 and 3.
