The Intel
®
Carrier Grade Server TIGPT1U can be configured with either a 250 watt AC-input
power supply or a 250 watt DC-input power supply.
The 250 watt power supply interconnects to the power interface board with a board-edge
connector. A board edge connector is also used by the extended front panel board to
interconnect to the power interface board. Power is then is carried to the 5 V riser board, the
midplane board, and the system baseboard via discrete cables connected to individual
connectors on the extended front panel board. The 250 watt power supply is capable of
handling the worst-case power requirements for a fully configured Intel
®
Carrier Grade Server
TIGPT1U. This includes one Intel

Pentium
®
4 Processor, 4 GB of memory, two hard drives at
18
W per drive (typical worst case 3.5-inch by 1.0-inch, 15 k RPM drive), and one 25 watt PCI
adapter.
