■ Set and enable an administrative password.
■ Set and enable a user password.
■ Enable password on boot.
■ Disable writing to the diskette drive when secure

Using Passwords
If only a supervisor password is set and enabled: Enter
this password to boot the server and run the SCU.
If both the user and administrative passwords are set
and enabled: Enter either one to boot the server. Enter
the administrative password to access the SCU or BIOS
Setup to change the system configuration.

The System has three Hot Swappable Power Supply
modules. Two of the Power Supply modules are
standard and one of the Power Supply modules is
optional. The first and second slots are basic power
supply module slots, the third slot is a redundant
power supply module slot. Each failed power supply
module can be removed without turning off power.
Each power supply module has two LEDs. Table 2-5
