1-20 Technical Information

KEYBOARD

The PS/2-style keyboard is standard equipment for the system. The keyboard provides a
numeric keypad, separate cursor control keys, and 12 function keys, capable of up to 48
functions. Status lamps on the keyboard indicate: Num (Numeric) Lock, Caps (Capital)
Lock, and Scroll Lock key status. The keyboard's six-pin connector is plugged into the rear
of the base unit. See Appendix A for a description of connector pin assignments.

MOUSE

A PS/2-compatible mouse is standard equipment for the system. Under normal conditions,
the mouse has a self-cleaning mechanism that prevents a buildup of dust or lint around the
mouse ball and tracking mechanism. Periodically, however, the mouse ball must be
cleaned. See Section 4, Maintenance and Troubleshooting, for information on cleaning the
mouse.

INTEGRATED TECHNOLOGIES

The following sections describe the technologies that provide desktop management, Plug
and Play support, power management, and security.

Desktop Management Interface

Desktop Management Interface (DMI) provides tracking information about the system at
power-on. At power-on, the system displays the system model number and the system
board serial number which is created during manufacturing at NEC.
DMI helps the user or service technician by providing information for quick technical sup-
port or software and hardware upgrades.

Plug and Play Support

The system comes with a Plug and Play BIOS which supports Plug and Play technology.
Plug and Play eliminates complicated setup procedures for installing Plug and Play expan-
sion boards.
With Plug and Play technology, there are no jumpers to set and no system resource con-
flicts to resolve. Plug and Play automatically configures the board for the system.
The system also supports non-Plug and Play boards. For information about installing ex-
pansion boards, see Section 3, Options.

Power Saving Features

Power saving options for PowerMate 486V Series systems include full power, partial
power reduction, and full power reduction modes of operation. The system provides many
ways to conserve energy, help the environment, and cut operating expenses.
