M120 Flexible PIC Concentrators (FPCs) LED
Bicolor LEDs located along the bottom of the craft interface displays the status of each
FPC and are labeled FPC0 through FPC5. For more information about the FPC LEDs
located on the craft interface, see “FPC LEDs on the M120 Craft Interface” on page 15.

M120 Compact FPCs (CFPCs) Description
A CFPC is a combination of a PIC and an FPC. It contains the interface circuitry and the
FPC as a single assembly. The WAN interface enables interconnection directly to SONET
transport facilities, eliminating the need for a separate SONET interface device.
The CFPCs install vertically in wo slots on the left side of the chassis in the front of the
router (see Figure 18 on page 55). The CFPC slots are numbered top to bottom CFPC0
and CFPC1. The CFPC slots feature a smaller form factor than the Type 1, 2, and 3 FPC
slots, to provide higher density for M120 10-gigabit interfaces.
