The line cards in EX9253 switches combine a Packet Forwarding Engine and Ethernet interfaces in a
single assembly. Line cards are field-replaceable units (FRUs) that you can install in the line card slots on
the front of the switch chassis. Line cards are hot-insertable and hot-removable: You can remove and
replace them without powering off the switch or disrupting switch functions. To maintain proper
cooling, you must install a replacement line card or a blank panel in the line card slot shortly after
removing a line card from the chassis.
