Features
Software Locks via the BIOS Setup
The BIOS Setup has software features that let you
control access to one or more parts of the system:
■
Set and enable a supervisor password.
■
Set and enable a user password.
■
Enable password on boot.
■
Disable writing to the diskette drive when secure
mode is set.
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 supervisor passwords are set and
enabled: Enter either one to boot the server. Enter the
supervisor password to access the SCU or BIOS Setup
to change the system configuration.
Hot Swap Power
The System can have up to four Hot Swappable Power
Supply modules. The first, second, and third slots are
basic power supply module slots, the fourth 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 shows the Power LED Indicators and Figure 2-9
shows the power supply module features.
A failed power supply module is signaled by the system
power on LED (green to amber), (see Figure 2-1, H),
the alarm LED on the failed power supply, and by
system maintenance software.
