M10i Internet Router Hardware Guide Figure 3: Midplane Flexible PIC Concentrators (FPCs) Flexible PIC Concentrators (FPCs) house the PICs that connect the router to network media (for information about PICs, see “Physical Interface Cards (PICs)” on page 10). On the M10i router, each FPC is built in (it cannot be removed from the chassis as on other M-series platforms) and corresponds to a horizontal row of PIC slots. The two FPCs on the M10i router are numbered 0 and 1, top to bottom.
Chapter 2: Hardware Component Overview The slot number for a PIC appears above its offline button on the HCM (see “PIC Offline Buttons” on page 19). The number of ports on a PIC depends on the type of PIC. PICs are hot-removable and hot-insertable. A removed PIC no longer receives or transmits data, and removing or inserting a PIC briefly interrupts forwarding of traffic through the remaining PICs. For PIC replacement instructions, see “Replacing a PIC” on page 96.
M10i Internet Router Hardware Guide For CFEB replacement instructions, see “Replacing a CFEB” on page 90. The CFEB communicates with the Routing Engine using a dedicated 100-Mbps Fast Ethernet link that transfers routing table data from the Routing Engine to the forwarding table in the integrated ASIC. The link is also used to transfer from the CFEB to the Routing Engine routing link-state updates and other packets destined for the router that have been received through the router interfaces.
Chapter 2: Hardware Component Overview ■ I2C/EEPROM containing the serial number and revision level ■ Two 512-KB boot flash EPROMs (programmable on the board) ■ One PowerPC 8245 integrated processor ■ Three LEDs—A green LED labeled OK, a red LED labeled FAIL, and a blue LED labeled MASTER indicate CFEB status. Table 7 on page 13 describes the LED states. ■ Power off button—Prepares the CFEB for removal from the router when pressed.
M10i Internet Router Hardware Guide Routing Engine The Routing Engine is an Intel-based PCI platform that runs JUNOS Internet software. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the router, control the router's interfaces, control some chassis components, and provide the interface for system management and user access to the router.
Chapter 2: Hardware Component Overview ■ CPU—Runs JUNOS Internet software to maintain the router's routing tables and routing protocols. It has a Pentium-class processor. ■ SDRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes. ■ Internal flash drive—This drive is optional.

Chapter 3 JUNOS Internet Software Overview The JUNOS Internet software is especially designed for the large production networks typically supported by Internet Service Providers (ISPs). It incorporates Internet Protocol (IP) routing software and software for management of interfaces, networks, and the router chassis. The JUNOS Internet software runs on the Routing Engine.
M10i Internet Router Hardware Guide ■ Routing Protocol Process on page 26 ■ VPNs on page 30 ■ Interface Process on page 31 ■ Chassis Process on page 31 ■ SNMP and MIB II Processes on page 31 ■ Management Process on page 31 ■ Routing Engine Kernel on page 31 Routing Protocol Process The JUNOS software routing protocol process controls the routing protocols that run on the router. The routing protocol process starts all configured routing protocols and handles all routing messages.
Chapter 3: JUNOS Internet Software Overview ■ ■ ■ BGP—Border Gateway Protocol, version 4, is an Exterior Gateway Protocol (EGP) that guarantees loop-free exchange of routing information between routing domains (also called autonomous systems). BGP, in conjunction with JUNOS routing policy, provides a system of administrative checks and balances that can be used to implement peering and transit agreements.
M10i Internet Router Hardware Guide by LDP can also traverse LSPs created by Resource Reservation Protocol (RSVP). ■ 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.
Chapter 3: JUNOS Internet Software Overview Routing and Forwarding Tables The primary function of the JUNOS routing protocol process is maintaining routing tables and using the information in them to determine active routes to network destinations. It copies information about the active routes into the Routing Engine's forwarding table, which the JUNOS kernel copies to the Packet Forwarding Engine.
M10i Internet Router Hardware Guide RIP) export the direct (interface) routes for the interfaces on which the protocol is explicitly configured. For each routing table, you can affect the routes that a protocol places into the table and the routes from the table that the protocol advertises by defining one or more routing policies and then applying them to the specific routing protocol.
Chapter 3: JUNOS Internet Software Overview by a VPN customer with connections to several various ISPs, or different connections to the same ISP in various geographic regions. ■ Carrier-of-Carrier VPNs—Carrier-of-carrier VPNs allow a VPN service provider to supply VPN service to a customer who is also a service provider. The latter service provider supplies Internet or VPN service to an end customer.
M10i Internet Router Hardware Guide Tools for Accessing and Configuring the Software The JUNOS CLI is the primary tool for accessing and controlling the JUNOS Internet software. You use it when accessing the router through the console or a connection to an out-of-band management network. The CLI includes commands for configuring router hardware, the JUNOS Internet software, and network connectivity. The JUNOS CLI is a straightforward command interface.
Chapter 4 System Architecture Overview The router architecture consists of two major components: ■ Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. ■ Routing Engine—Provides Layer 3 routing services and network management. The Packet Forwarding Engine and the Routing Engine perform independently but communicate constantly through a 100-Mbps internal link.
M10i Internet Router Hardware Guide ■ Midplane—Transports packets, notifications, and other signals between the PICs and the Packet Forwarding Engine (as well as other system components). ■ Physical Interface Card (PIC)—Physically connects the router to fiber-optic or digital network media. A controller ASIC in each PIC performs control functions specific to the PIC media type.
Chapter 4: System Architecture Overview Figure 12: Packet Forwarding Engine Components and Data Flow Routing Engine Architecture The Routing Engine is an Intel-based PCI platform running the JUNOS Internet software, which Juniper Networks has developed and optimized to handle large numbers of network interfaces and routes. The software consists of a set of system processes running in protected memory modules on top of an independent operating system.
M10i Internet Router Hardware Guide Routing Engine Functions The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the router. These routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engine. For more information about the processes, see JUNOS System Basics and Services Command Reference.

M10i Internet Router Hardware Guide Table 14: Site Preparation Checklist (continued) Item or Task For More Information Plan rack location, including required space clearances. “Clearance Requirements for Airflow and Hardware Maintenance” on page 44 Performed By Date “Rack Size and Strength” on page 42 If a rack is used, secure rack to floor and building structure.
Chapter 5: Preparing for Router Installation NOTE: We recommend that you do not install the router in a cabinet. If you mount the router in a cabinet, be sure that sufficient room is provided for cable management and cables. The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 8.7 in. (22.1 cm) high, 18 in. (45.7 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the mounting brackets extend the width to 19 in. (48.3 cm).
M10i Internet Router Hardware Guide Spacing of Mounting Holes The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so the router can be mounted in any rack that provides holes spaced at that distance. Connection to Building Structure Always secure the rack to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.

M10i Internet Router Hardware Guide Radio Frequency Interference You can reduce or eliminate the emission of radio frequency interference (RFI) from your site wiring by using twisted-pair cable with a good distribution of grounding conductors. If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
Appendix C: Power Requirements, Guidelines, and Specifications ■ Power consumption for minimum configuration: Base system + 1 CFEB + 2 HCMs + 1 Routing Engine + 1 PIC = 0.7 A + 1.4 A + 2(0.2 A) + 0.625 A = 0.7 A + 1.4 A + 0.4 A + 0.625 A = 3.125 A @ 48 V = 150 W DC ■ Power consumption for maximum configuration: Base system + 2 CFEBs + 2 HCMs + 2 Routing Engines + 8 PICs = 0.76 A + 2(1.4 A) + 2(0.2 A) + 8(0.625 A) = 0.7 A + 2.8 A + 0.4 A + 5 A = 8.9 A @ 48 V = 427.
M10i Internet Router Hardware Guide A pair of threaded inserts (PEM nuts) are provided on the right rear of the chassis for connecting the router to earth ground. CAUTION: Before router installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit).

Appendix D Cable Specifications ■ Network Cable Specifications and Guidelines on page 183 ■ Cable Specifications for Routing Engine Management Interfaces on page 187 Network Cable Specifications and Guidelines The various PICs supported on the router accept different kinds of network cable, including multimode and single-mode fiber-optic cable.
M10i Internet Router Hardware Guide Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances. It is consequently more expensive.
Appendix D: Cable Specifications transmit enough power to saturate the receivers on PICs that have a shorter reach. Specifically, LR transceivers can saturate IR PICs, and both IR and LR transceivers can saturate SR PICs. Transceivers in the same reach class can also saturate one another. To prevent saturation, you might need to attenuate power at the PIC receiver, particularly if you know that it has a shorter reach than the transceiver that is sending the signal.
M10i Internet Router Hardware Guide Factors that can cause link loss include higher-order mode losses, modal and chromatic dispersion, connectors, splices, and fiber attenuation. Table 23 on page 186 lists an estimated amount of loss for the factors used in the following sample calculations. For information about the actual amount of signal loss caused by equipment and other factors, refer to vendor documentation.
Appendix D: Cable Specifications for seven connectors (0.5 dB per connector, or 3.5 dB). The power margin (PM) is calculated as follows: PM = PB – LL PM = 13 dB – 8 km (0.5 dB/km) – 7 (0.5 dB) PM = 13 dB – 4 dB – 3.5 dB PM = 5.5 dB In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power.
