M40e PICs Description
PICs physically connect the M40e Multiservice Edge Router to network media. They are housed in Flexible PIC Concentrators (FPCs); for more information about FPCs, see M40e Flexible PIC Concentrators (FPCs) Description.
PICs receive incoming packets from the network and transmit outgoing packets to the network, performing framing and line-speed signaling for their media type as required. PICs also encapsulate outgoing packets received from the FPCs before transmitting them. The controller ASIC on each PIC performs additional control functions specific to the PIC media type.
The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, IP Services, and SONET/SDH interfaces. For a complete list of supported PICs, see M40e PICs Supported. For a complete list of end-of-life PICs, see End-of-Life PICs Supported (M40e Router).
Some PICs accept small form-factor pluggables (SFPs), which are fiber-optic transceivers that can be removed from the PIC. Various SFPs have different reach characteristics. You can mix them in a single PIC and change the combination dynamically. SFPs are hot-removable and hot-insertable, as described in M40e Field-Replaceable Units (FRUs). For SFP replacement instructions, see Replacing an SFP in an M40e PIC. For information about PICs that use SFPs, see the M40e Multiservice Edge Router PIC Guide.
M40e PIC Slots
The number of ports on a PIC depends on the type of PIC. You can install up to four PICs in each Type 1 FPC and one PIC in each Type 2 FPC. 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 installed on Type 1 FPCs and Type 2 FPCs are hot-removable and hot-insertable, as described in M40e Field-Replaceable Units (FRUs). For PIC replacement instructions, see Replacing a PIC in an M40e Router.
M40e PIC Components
Most PICs supported on the M40e Multiservice Edge Router have the following components. For complete specifications, see the M40e Multiservice Edge Router PIC Guide.
- 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. For more information, see the M40e Multiservice Edge Router PIC Guide.
- Offline button—Prepares the PIC for removal from the FPC when pressed. For the PICs that install on an Type 1 FPCs, the offline button for each PIC is next to it on the FPC card carrier. For the PICs that install on an Type 2 FPCs, the offline button is on the PIC faceplate.
