If you must insert the DPC into a bag by yourself, first lay the DPC horizontally on a flat,
stable surface, sheet metal side down. Orient the DPC with the faceplate facing you.
Carefully insert the DPC connector edge into the opening of the bag, and pull the bag
toward you to cover the DPC.
Never stack a DPC under or on top of any other component.

The MX240 router can have one Flexible PIC Concentrator (FPC) installed horizontally
in the front of the chassis. For optimum router performance, verify the condition of the
FPC.
On a regular basis:
Check the LEDs on the craft interface directly above the FPC. The green LED labeled
lights steadily when an FPC is functioning normally.
OK
Check the LED on the FPC. If the FPC detects a failure, the FPC sends an alarm
OK/FAIL
message to the Routing Engine.
