Dell EMC PowerEdge R240 Installation and Service Manual
Disabling forgotten password
The software security features of the system include a system password and a setup password. The password jumper enables or disables password features and clears any password(s) currently in use.
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.
