ACX7300 Flexible PIC Concentrators

SUMMARY Learn about the ACX7K3-FPC-2CD4C and ACX7K3-FPC-16Y Flexible PIC Concentrator (FPC), its features, specifications, and supported port speeds.

The ACX7348 router has a fixed Flexible PIC Concentrator (FPC) and two pluggable FPCs. The ACX7K3-FPC-2CD4C and ACX7K3-FPC-16Y are the pluggable FPCs that are installed horizontally in the front of the chassis. You can install these pluggable FPCs into any of the three FPC slots on the ACX7348 chassis. You can remove and replace the pluggable FPCs without powering off the router or disrupting router functions.
