FPC Summary
On J-series Services Routers, an FPC and a PIM are the
same physical unit.
FPC or PIM slot number.Slot
State of the slot:
■
Dead—Held in reset because of errors.
■
Diag—Slot is being ignored while the FPC or PIM
is running diagnostics.
■
Dormant—Held in reset.
■
Empty—No FPC or PIM is present.
■
Online—FPC or PIM is online and running.
■
Probed—Probe is complete. The FPC is awaiting
restart of the Packet Forwarding Engine (PFE).
■
Probe-wait—The FPC is waiting to be probed.

J-series Services Routers do not monitor and report the
temperature of PIMs.
Temperature of the air passing by the FPC, in degrees
Celsius.
Temp (C)
Total—Total percentage of CPU being used by the
FPC or PIM processor.
Interrupt—Of the total CPU being used by the FPC or
PIM processor, the percentage being used for
interrupts.
CPU
Utilization
(%)
Total DRAM, in megabytes, available to the FPC or
PIM processor.
Memory
DRAM (MB)
If the heap space utilization exceeds 80 percent, a
memory leak might be occurring.
Heap—Percentage of heap space (dynamic memory)
being used by the FPC or PIM processor.
