Flexible PIC Concentrators (FPCs) on the ACX7348 router are eld-replaceable units (FRUs) that can be
installed in FPC slots on the front of the chassis. The FPCs are hot-pluggable—you can remove and
replace them without powering o the router.
Before you replace an FPC from the router chassis:
• Ensure that you have taken the necessary precauons to prevent electrostac discharge (ESD)
damage.
• If there are any opcal cables (including transceivers) installed in the FPC, remove them before you
replace the FPC.
• Ensure that you have the following equipment available before replacing an FPC:
• Anstac bag or anstac mat
• Replacement FPC or a cover for the empty slot
• ESD grounding strap to wrap around your bare wrist and connect to an ESD point on the chassis
