PTX3000 PIC Description

PIC Slots

Up to eight PICs install vertically in the front of the PTX3000 (Figure 1). The PIC slots are numbered 1, 3, 5, and 7 in the upper chassis, and 9, 11, 13, and 15 in the lower chassis.

The PIC in the slot to the right of an FPC is associated with that FPC. Each PIC requires an FPC to be installed in the adjacent FPC slot to its left as specified in Table 1. For example, the PIC in slot 1 is associated with the FPC in slot 0.

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. Blank PICs resemble other PICs but do not provide any physical connection or activity. PICs are hot-removable and hot-insertable.

In the CLI, all PTX3000 PICs are represented as pic0.

PIC Function

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.

PICs Supported

See PICs Supported on the PTX Series for a complete list of PICs supported on the PTX3000.

PIC Components

Figure 2 shows an example of a PIC supported on the PTX3000. PICs have an upper ejector handle and a lower ejector handle.
