System Overview 1-13
Hard Disk Drive
A standard 2.5-inch, 9.5 mm or 12.7 mm hard disk drive ships with the system.
Some of the earlier non-AGP 200-MHz, 233-MHz, and 266-MHz systems have
a non-user replaceable hard disk drive.
File Bay
The NEC Versa LX ships with a 3.5-inch, 1.44 MB diskette drive or the
SuperDisk drive installed in the file bay.
VersaBay III
A 24X CD-ROM drive or a DVD-ROM drive comes installed in the NEC
VersaBay III on the front of the system.
CPU Board
The CPU board is a rectangular-shaped board located above the main board.
The CPU board is part of a subassembly, which includes a heat sink and the
CPU board.
Audio Board
The audio board provides the NEC Versa system with its audio I/O capabilities
via a line-in jack, headphone and microphone jacks. It is situated on top of the
main board.
CMOS Battery
The lithium battery (3 Volts, 30 mAH capacity) is attached to P28 on the main
board. It provides short-term 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 like date, time,
drives, and memory. The CMOS battery has a useful life of approximately three
years.
Bridge Battery
The bridge battery saves the memory contents and system status for up to 5
minutes while changing the main battery. It is connected to the main board via
connector P5. The AC adapter maintains voltage in the bridge battery when the
system is powered on or off. The bridge battery stores 7.2 Volts, 70 mAH.
