2.2 Network Processors
2.2.1 Description
• Two Cavium Octeon II CN68XX.
• Each processor provides up to 32 cores running at up to 1.5 Ghz providing 96,000 MIPS.
• Four memory channels per processor; 1333 DDR3 UDIMM with ECC.
• Interlaken lanes x4 between the two OCTEON II processors
2.2.2 eUSB Flash Modules
Each NPU supports one Solid State Drive. Those modules are NAND flash disks modules with USB 2.0
interfaces.
2.3 Unit Computer
2.3.1 Description
• Single core Freescale P2010 1GHz processor
• 1GB DDR3 SO-UDIMM, ECC
• 2x 128MByte NOR FLASH with dual Image Support
• 10/100/1000Base-T RJ45 connector on the front panel
• RTC Clock support
2.3.2 Real Time Clock
The AT8242 is a battery-less board. The real time clock integrated in the Unit Computer is powered by the
suspend power when available. A SuperCap provides sufficient power to retain the real time clock for a typical
duration of 2hrs. The real time clock precision is 100ppm or better.
2.4 Switch
