The router is a quarter-rack chassis that supports up to six Flexible PIC Concentrators (FPCs). Four slots accept FPCs of Types 1, 2, and 3 and two slots accept Compact FPCs (cFPCs). Each FPC can be configured with a variety of network media types, altogether providing up to 130 physical interface ports per system. The cFPC slots are identical to the Type 1, 2, and 3 FPC slots, but feature a smaller form factor to provide higher density 10-Gigabit interfaces. The router height of 20.75 in. (52.71 cm) enables stacked installation of four routers in a single floor-to-ceiling rack, for increased port density per unit of floor space. In a standalone configuration, the router's maximum aggregate throughput is 120 Gbps, full duplex.
The router is shipped in a cardboard box strapped securely to a wood pallet. Plastic straps secure the top and bottom in place. The router chassis is bolted to this pallet. Quick Start installation instructions and a cardboard accessory box are also included in the shipping container.
