Datasheet

The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, Services,

and SONET/SDH interfaces. You can install PICs of different media types on the same

router as long as the router supports those PICs.

Blank PICs resemble other PICs but do not provide any physical connection or activity.

When a slot is not occupied by a PIC, you must insert a blank PIC to fill the empty slot

and ensure proper cooling of the system.

Four PIC slots are located in one Flexible PIC Concentrator (FPC), FPC0, which is built in

to the chassis. The PIC slots are numbered from 0 (zero) through 3, right to left. The

number of ports on a PIC depends on the type of PIC.

The M7i router has a maximum throughput of 3.2 Gbps full duplex for the FPC with 4 PIC

slots. Inserting a combination of PICs with an aggregate higher than the maximum

throughput is supported, but constitutes oversubscription of the FPC. The fixed interface

card (FIC) has a maximum throughput of 1 Gbps full duplex.

PICs are hot-removable and hot-insertable.

Most PICs supported on the M7i router have the following components.

•

One or more cable connector ports—Accept a network media connector.

•

LEDs—Indicate PIC and port status. Most PICs have an LED labeled STATUS on the

PIC faceplate. Some PICs have additional LEDs, often one per port. The meaning of

the LED states differs for various PICs.

•

Ejector lever—Controls the locking system that secures the PIC in the card cage.

M7i PIC LEDs

LEDs indicate PIC and port status. Most PICs have an LED labeled STATUS on the PIC

faceplate. Some PICs have additional LEDs, often one per port. The meaning of the LED

states differs for various PICs. For more information, see the M7i Multiservice Edge Router

PIC Guide.
