The NA551 is 2U rack-mountable network appliance with the ability to support up to 26 Gigabit Ethernet ports and up to 6-group LAN bypass segment. The outstanding NA-551 supports the 3rd Generation and 2nd Generation Intel® Core™ processors with Intel® C206 chipset. It comes with four unbuffered ECC or non-ECC DDR3 1333 MHz DIMM sockets with up to 16GB memory and two front-accessible hot-swappable 3.5″ SATA hard drive bays. Moreover, NA551 supports power redundant (1+0 or 1+1) for better fail over protection. For greater flexible and easy maintenance, the NA551 has three front-accessible expansion slots that allow developers to configure PCIe LAN modules based on their solution requirements. Additionally, considering to expansibility for users, one Mini PCI slot is available for third-party cards. Its friendly design gives users the advantage of being able to develop network security solutions according to their demands and reduce time to market.
