2-8 System Configuration and Setup
The CMOS battery provides battery backup and prevents data loss in the system’s
complementary metal-oxide semiconductor (CMOS) RAM. This memory area contains
information on the system’s configuration (for example, date, time, drives, and memory).
System Power Cord
This equipment uses an ungrounded power cable. Replace the cord if it becomes damaged.
This equipment uses an ungrounded power cable. Replace the cord if it
becomes damaged. U.S. and Canadian replacement cords must be UL-approved (CSA certified
in Canada) type SPT-2, 18 AWG, 2-conductor cord with a permanently attached NEMA type
5-15P plug at one end, and a permanently attached connector body on the other. Cord length
may not exceed 15 feet.
Outside the U.S. and Canada the cord must be rated for at least 250VAC at 10 amps, and must
indicate international safety agency approval. The plug must be a type appropriate for the country
where it is used. Check with your local dealer for HAR type 18 AWG, 2 conductor cord, or better.
Obtain replacement cords at an authorized service center. The replacement must be of the same
type and voltage rating as the original cord.
Disconnect all supply lines before the hinged front cover is removed. Replace the hinged cover
before the unit is restarted.
BIOS Setup
The NEC Versa VXi computer comes with a BIOS Setup hardware program that allows viewing
and setting of system parameters. BIOS Setup also allows setting of password features that
protect the system from unauthorized use.
Use BIOS Setup to:
!
set the current time and date
!
customize the operating system to reflect the computer hardware
!
secure the system with a password
!
balance performance needs with power conservation.
Access the BIOS utility at power-on. Press
F2
when the following prompt appears.
Press <F2> to Enter BIOS Setup.
When you press
F2
to enter BIOS Setup, the system interrupts the Power-On Self-Test (POST)
and displays the current CMOS RAM settings.
If the system detects an error during POST, it prompts you with a double beep and a message:
“Press <F1> to resume.” If you press
F1
, the system enters BIOS Setup automatically. If you
want to fix the error, carefully read the error message that appears above the prompt (taking
notes if you want), and press
F2
. You will see this message if the CMOS battery becomes fully
discharged.
