Number	number of the backplane is also the serial number
	of the router chassis.
Description	Brief description of the hardware item.

FPC Summary

Additional Information

Use this serial number when you need to contact customer support about the router chassis.

For J-series PIMs, the description lists the number and type of the ports on the PIM—identified in the display as a PIC.

Slot	FPC or PIM slot number.	On J-series Services Routers, an FPC and a PIM are the
		same physical unit.
State	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.
Temp (C)	Temperature of the air passing by the FPC, in degrees	J-series Services Routers do not monitor and report the

(%)
	Interrupt—Of the total CPU being used by the FPC or
	PIM processor, the percentage being used for
	interrupts.
Memory	Total DRAM, in megabytes, available to the FPC or
