System Security

To help prevent unauthorized entry or use of the system, the system includes a three-position key lock/switch to permit selected access to drive bays (position is communicated to BMC). The system also includes server management software that monitors the chassis intrusion switch.

Software Locks via the SSU or BIOS Setup

The SSU provides a number of security features to prevent unauthorized or accidental access to the system. Once the security measures are enabled, access to the system is allowed only after the user enters the correct password(s). For example, the SSU allows:

∙Enable the keyboard lockout timer so the server requires a password to reactivate the keyboard and mouse after a specified time-out period of 1 to 120 minutes

∙Set and enable administrator and user passwords

∙Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset and power switches

∙Activate a hot key combination to enter secure mode quickly

∙Disable writing to the diskette drive when secure mode is set

Using Passwords

If a user password is set and enabled, but an administrator password is not set, a user password must be entered to boot the system and run the SSU.

If both a user and administrator password is set:

∙Enter either one to boot the server and enable the keyboard and mouse

∙Enter the administrator password to access the SSU or BIOS Setup to change the system configuration

Secure Mode

Configure and enable the secure boot mode by using the SSU. When secure mode is in effect,

∙The system can boot and the operating system runs, but the user password must be entered for a user to use the keyboard or mouse

∙The system cannot be turned off or reset from the front panel switches

Secure mode has no effect on functions enabled via the Server Manager Module or power control via the real-time clock (RTC).
