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 16 on page 42 indicates the number of PICs supported by each FPC.
