Flexible PIC Concentrators

The FPCs house the PICs used in the router and connect them to other router components. FPCs install into the front of the router in either a vertical or horizontal orientation, depending on the router. A compatible FPC can be installed into any available FPC slot, regardless of the PICs it contains. If a slot is not occupied by an FPC, a blank FPC panel must be installed to shield the empty slot and allow cooling air to circulate properly through the FPC card cage. Some routers support more than one type of FPC. Generally, the FPCs for each router are unique to that router; however, M20 and M40 FPCs are interchangeable, and the M40e and M160e type 1 FPCs are also interchangeable.
