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 43. 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. See your Product
