CAUTION: Before you begin any of the procedures in this section, read "Safety Instructions."

NOTICE: Be careful when opening the computer cover to ensure that you do not inadvertently disconnect cables from the system board.

System Board Connectors and Sockets

This computer supports two types of system boards—a one-piece system board (shown in the illustration) and a two-piece, riser system board.

Socketed Microprocessor

The 478-pin, socketed Intel® Pentium® 4 microprocessor, shown above with the heat sink attached, contains an integrated 8-KB primary (L1) cache with a secondary (L2) 256-KB Advanced Transfer Cache that resides in the processor's core and runs at the processor's internal clock speed.

The socketed microprocessor inserts into the ZIF connector mounted on the system board. A clip secures the heat sink to the connector.

Power Supply

The 250-W power supply can operate from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz. The power supply provides the DC operating voltages and currents listed in the following table.

Output Voltage	Minimum Current (A)	Maximum Current (A)1	Peak Current (A)2
+12 VDC	1.0	10.04	12.0
+5 VDC	4.0	22.04	12.0
+3.3 VDC	1.0/0.03	14.04	12.0
–12 VDC	0.0	1.0	12.0
+5 VFP	0.0	2.0	12.0
When the current load is outside of the ranges listed, but within each specified output current range, the +5-V, +12-V, and +3.3-V outputs are allowed to regulate at +/–10% of nominal DC voltages. 1Maximum continuous total DC output cannot exceed 200 W. Maximum continuous combined load on +5-VDC and +3.3-VDC outputs cannot exceed 135 W. 2Peak +12-VDC output power (up to 12 A) does not exceed 15 seconds in duration. In this condition, the tolerance on the +12-V output is allowed to be +/–10%. 3In system applications where +3.3 VDC is not used, these values may be 0 A without affecting the regulation on the other outputs. 4The required full load combinations are adjusted so that the total output power is less than or equal to 250 W.
