PTX Series PIC Description on page 36
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.
PICs are hot-removable and hot-insertable. You can install up to two PICs in each Type
5 FPC. Type 5 PICs have an upper ejector handle and a lower ejector handle.
The PTX Series Packet Transport Switches support 10-Gigabit Ethernet, 40-Gigabit
Ethernet, and 100-Gigabit Ethernet 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.
Figure 20 on page 37 shows a Type 5 PIC supported for the packet transport switch.
