FPCs and PICs
A Flexible PIC Concentrator (FPC) occupies two Dense Port Concentrator (DPC) slots on an MX240,
MX480, MX960 router. Each FPC supports up to two Physical Interface Cards (PICs). FPCs install vertically
in the MX960 router chassis, and horizontally in the MX480 and MX240 router chassis. The maximum
number of supported FPCs varies per router:
Physical Interface Cards (PICs) provide physical interfaces for MX240, MX480, MX960 routers. They install
into the Flexible PIC Concentrators (FPCs). PICs and FPCs function similarly to MICs and MPCs. The
maximum number of supported PICs varies per router:
DPCs
A Dense Port Concentrator (DPC) provides multiple physical interfaces and Packet Forwarding Engines
(PFEs) on a single board that installs into a slot within the MX240, MX480, and MX960 routers. DPCs
install vertically in the MX960 router chassis and horizontally in the MX480 and MX240 router chassis.
The maximum number of supported DPCs varies per router:
•
MX960 router— up to 12 DPCs
•
MX480 router— up to 6 DPCs
•
MX240 router— up to 3 DPCs
