IOC cover, which functions as a ground plane
and a stiffener.
Fabric interfaces.
Two Gigabit Ethernet interfaces that allow control information,
route information, and statistics to be sent between the Routing Engine
and the CPU on the IOCs.
Two interfaces from the SCBs
that enable the boards to be powered on and controlled.
Physical IOC connectors.
Packet Forwarding Engines.
Midplane connectors and power circuitry.
Processor subsystem, which includes a 1.2-GHz CPU, system
controller, and 1 GB of SDRAM.
LEDs on the 4–port 10–Gigabit Ethernet faceplate
indicate the port status. LEDs are labeled top to bottom 0/0 through 0/3 (see Table 4).
LEDs on the 40–port Gigabit Ethernet faceplate indicate
the port status. LEDs are labeled horizontally and left to right 0/0 through 0/5, 1/0 through 1/5, 2/0 through 2/5, and 3/0 through 3/5 (see Table 5).

Two LEDs, located on the craft interface above the IOC,
display the status of the IOC and are labeled OK and FAIL. For more information on the IOC LEDs
located on the craft interface, see IOC and SPC LEDs.
