3.1 Brief Guide of PPAP-3714L

PPAP-3714L is an Intel®Pentium

™

4 based board with Cavium Nitrox Lite CN1010X supporting

IPSec/SSL. The onboard Cavium security processor provides a cost advantage and the flexibility to implement various networking appliances. The PPAP-3714L has the capability of processing up 1GB IPSec traffic or 7000 RSA operations per second.

PPAP-3714L is a Communication Appliance computing board based on Intel 875P chipset technology. PPAP-3714L has ten on-board LAN ports to serve communication appliances, such as Firewall, which needs sufficient ethernet ports to connect external network (internet), demilitarized zone and internal network. Different I/O management policies can be applied respectively to individual network to achieve the highest security level. The target market segment is communication appliance including Virtual Private Network, Load Balancing, Quality of Service, Intrusion Detection, Virus Detection, Firewall and Voice Over IP.

This PPAP-3714L system board is utilized with Intel® mPGA Celeron® and Intel® mPGA

Pentium® 4 processors, and 184-pin DIMM. The enhanced on-board PCI IDE interface supports

2 drives up to PIO mode 4 timing and Ultra DMA/100 synchronous mode feature. The on-board
