Page 40: M40E Pics Description
M40e System Description on page 3 M40e PIC Overview M40e PICs Description PICs physically connect the M40e Multiservice Edge Router to network media. They are housed in Flexible PIC Concentrators (FPCs). 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.
Page 41: M40E Pic Slots
PICs installed on Type 1 FPCs and Type 2 FPCs are hot-removable and hot-insertable. M40e PIC Components Most PICs supported on the M40e Multiservice Edge Router have the following components: One or more cable connector ports—Accept a network media connector.
Page 42: M40E Fpc Function
Flexible PIC Concentrators (FPCs) house the PICs that connect the router to network media (for information about PICs, see “M40e PICs Description” on page 12). The main function of an FPC is to connect the PICs installed in it to the other router components.
Page 43: M40E Fpc Components
Chapter 2: M40e Hardware Components Figure 5: Front of M40e Chassis with Four-PIC FPC Installed in Slot FPC0 M40e FPC Components An FPC has the components: FPC card carrier—Houses the ASICs, connectors, and processor subsystem. Two I/O Manager ASICs—Parse Layer 2 and Layer 3 data and perform encapsulation and segmentation.

The LEDs for each FPC are located on the router craft interface. For more information, see “FPC LEDs and Controls on the M40e Craft Interface” on page 38. Offline button—Prepares the FPC for removal from the router when pressed. Like the LEDs, an offline button is located on the craft interface.
Page 45: M40E Fpcs Supported
Troubleshooting FPCs on the M40e Router on page 152 M40e FPCs Supported The M40e router supports the FPCs listed in Table 3 on page 17. NOTE: Inserting a combination of PICs with an aggregate throughput higher than the maximum throughput per FPC is supported but constitutes oversubscription of the FPC.

PCG 0 PCG 1 as shown in “M40e Chassis Description” on page 8. The PCGs generate a 125-MHz clock signal used to gate packet processing. During startup, the active Routing Engine determines which PCG is master and which is backup, and the MCS relays the decision to the PCGs and to the modules and ASICs in the Packet Forwarding Engine that use the clock signal.

There are two load-sharing, pass-through power supplies located at the bottom rear of the chassis, as shown in “M40e Chassis Description” on page 8. The power supplies connect to the midplane, which distributes power to router components according to their individual voltage requirements.

Page 82: Ipv6 Routing Protocols
M40e Multiservice Edge Router Hardware Guide MPLS—Multiprotocol Label Switching enables you to configure LSPs through a network either manually or dynamically. You can control how traffic traverses the network by directing it through particular paths, rather than relying on an IGP's least-cost algorithm to choose a path.
Page 83: Routing Policy
Policies applied when the routing protocol is advertising routes that are in the routing table are called export policies because the routes are being exported from the routing table. In other words, the terms import and export are used with respect to the routing table. Copyright © 2010, Juniper Networks, Inc.

M40e Multiservice Edge Router Hardware Guide Routing policy enables you to control (filter) which routes are imported into the routing table and which routes are exported from the routing table.

The router uses either AC or DC power. There are two load-sharing, pass-through power supplies located at the bottom rear of the chassis, as shown in “M40e Chassis Description” on page 8. The power supplies connect to the midplane, which distributes power to router components according to their individual voltage requirements.
