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 41. The password jumper enables these password features or disables
them and clears any password(s) currently in use.
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions
in your Product Information Guide .
