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.

Maintaining MX240 FPCs
Purpose 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.
Action On a regular basis:
• Check the LEDs on the craft interface directly above the FPC. The green LED labeled
OK lights steadily when an FPC is functioning normally.
• Check the OK/FAIL LED on the FPC. If the FPC detects a failure, the FPC sends an alarm
message to the Routing Engine.
• Issue the CLI show chassis fpc command to check the status of the installed FPC. As
shown in the sample output, the value Online in the column labeled State indicates
that the FPC is functioning normally:
user@host> show chassis fpc
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Online 33 8 0 1024 18 30
1 Online 37 3 0 1024 12 21
2 Empty
For more detailed output, add the detail option. The following example does not specify
a slot number, which is optional:
