minutes or use a screwdriver to touch the

Supervisor and HDD passwords:
The Supervisor password and HDD password (HDD-1
and HDD-2) are security features that are used to
protect the system and the hard disk drive data from
unauthorized access. No overriding capability is pro-
vided, so it cannot be reset if forgotten. If the cus-
tomer forgets the Supervisor password, the planar
board must be replaced. If the customer forgets the
HDD password, the hard disk drive must be replaced.
