FPC is hot-swappable in all platforms except M5 and M10 which is using FEB. In case of TX Matrix Plus router with 3D SIBs, replace slot-number with a value from 0 through 63. First, check the Juniper Port Checker to ensure that the port configuration you want is supported. Whether or not a new hardware component is powered on depends on the availability of power in the PEM. For example, the following commands have the same result: content_copy zoom_out_map. Multiple EX switches when gracefully shut down seem to come back up with bad blocks and/or corrupted primary partitions. On Juniper Networks Junos OS devices, a stream of TCP packets sent to the Routing Engine (RE) may cause mbuf leak which can lead to Flexible PIC Concentrator (FPC) crash or the system to crash and restart (vmcore). In QFX10008 or QFX10016, FPC can reboot for various unexpected reasons. FPC core analysis would explain further what the offending process was, however, a core would be best analyzed on a JTAC case. 1R1, when you take an FPC offline by using the request chassis fpc slot offline command, the screen displays the following message.
