System Overview 1-19
System Security
To help prevent unauthorized entry or use of the system, the system includes a full
lockable front panel and Server Management software that monitors the system
intrusion switches.
Security with Mechanical Locks and Monitoring
The front panel of the tower-based system contains a mechanical lock and an intrusion
switch to prevent access to the front of the computer chassis. The computer chassis
includes an intrusion switch on the side cover. When any of these covers are opened,
the switch transmits an alarm signal to the system board, where server management
software processes the signal.
Security with the rack-mount system is identical to the tower-based system stated
above, except that the mechanical locks are on the front and rear doors of the rack
cabinet.
Software Locks via the System Setup Utility
The BIOS Setup Utility 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:
!
Enable the keyboard lockout timer so that the server requires a password to
reactivate the keyboard and mouse after a specified time-out period
1 to
120minutes.
!
Set and enable an administrative password.
!
Set and enable a user password
!
Set secure mode to prevent keyboard or mouse input and to prevent use of the
front panel reset and power switches.
!
Disable writing to the diskette drive when secure mode is set.
Reconfiguration
If a CPU or a memory DIMM board error was detected during execution of POST
(Power On Self-Test) after system power is turned on, the reconfiguration function
isolates the failed CPU or memory DIMM and continues operation. You should replace
the failed device as soon as possible.
This function is enabled only when the following system requirements are met:
!
Two CPUs are installed.
!
Four or six memory DIMMs are installed.
A CPU or memory DIMM error may be viewed on the screen while POST is running or
by entering BIOS Setup. It may also be viewed when the ESMPRO Suite program is
installed and operating.
