T4000 PIC Description

PICs provide the physical connection to various network media types, receiving incoming

packets from the network and transmitting outgoing packets to the network. During this

process, each PIC performs framing and line-speed signaling for its media type. Before

transmitting outgoing data packets, the PICs encapsulate the packets received from the

FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the

media type of that PIC.

The router supports various PICs, including ATM, Ethernet, and SONET/SDH interfaces.

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.

PICs are hot-removable and hot-insertable. Type 2 PICs have captive screws at their

upper and lower corners. Type 3 PICs have an upper ejector handle and a lower captive

screw. Type 4 and Type 5 PICs have an upper ejector handle and a lower ejector handle.

Table 1 on page 3 indicates the number of PICs supported by each FPC.
