Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are discussed
in detail in "Using the System Setup Program" on page 29. The password jumper enables these password
features or disables them and clears any password(s) currently in use.
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. Before performing any procedure, see your
Product Information Guide
