Safety Requirements, Warnings, and Guidelines • • Hot-removable and hot-insertable FRUs—You can remove and replace these components without powering down the router or disrupting the routing functions. FRUs that require powering down the router—You must power down the router before removing these components. Table 2 lists the FRUs for the M5 and M10 routers.
Chapter 2 Hardware Component Overview This chapter provides an overview of the hardware components on the M5 and M10 Internet routers: • Chassis on page 5 • Packet Forwarding Engine on page 8 • Routing Engine on page 12 • Craft Interface on page 14 • Power Supplies on page 16 • Fan Tray on page 19 • Cable Management System on page 20 Chassis The router chassis is a rigid sheet metal structure that houses the other hardware components. The chassis is 17.5 in. (44.5 cm) wide and 24 in.
Chassis Figure 1: Front of M5 Chassis 1301 PICs R Mounting ear ESD point Craft interface 1300 Figure 2: Front of M10 Chassis Mounting ear Craft interface 6 M5 and M10 Internet Routers Hardware Guide PICs ESD point
Chassis Figure 3: Rear of Chassis Forwarding Engine Board Routing Engine cover Power supply B 1302 Power supply A ESD point Fan tray The chassis includes two electrostatic discharge (ESD) points (banana plug receptacles) for electrical safety, one front and one rear, as shown in Figure 1, Figure 2, and Figure 3. Before removing or installing components of a functioning router, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist.
Packet Forwarding Engine Description Value Weight, minimum configuration 57 lb (25.8 kg) Thermal output 2550 BTU/hour Packet Forwarding Engine The Packet Forwarding Engine is a multicomponent system that uses application-specific integrated circuits (ASICs) to perform Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. The ASICs include the Distributed Buffer Manager ASIC, Internet Processor II ASIC, I/O Manager ASIC, and media-specific controller ASICs.
Packet Forwarding Engine • • Power distribution—The midplane distributes power to all router components from the power supplies attached to it. Signal connectivity—The midplane transports the signals exchanged by system components for monitoring and control purposes. Figure 4: Midplane 1304 Midplane Physical Interface Cards (PICs) Physical Interface Cards (PICs) physically connect the router to network media.
Packet Forwarding Engine Quad-wide PICs, such as the 4-port Gigabit Ethernet and OC-48/STM-16 SONET/SDH PICs, occupy all four slots in an FPC. Some quad-wide PICs might not be supported on both the M5 and M10 routers; for more information, see the M5 and M10 Internet Routers PIC Guide. Both regular and quad-wide 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.
Packet Forwarding Engine Engine routing link-state updates and other packets destined for the router that have been received through the router interfaces. The ASICs and other components on the FEB provide the following functions: • Route lookups—The Internet Processor II ASIC on each FEB performs route lookups using the forwarding table stored in SSRAM.
Routing Engine • Processor subsystem—Manages FEB functions and handles exception packets. The processor has the following components: • One PowerPC 603e processor • Parity-protected Level 2 cache • Parity-protected DRAM • EEPROM—Stores the serial number and revision level. • 19.44-MHz stratum 3 reference clock—Generates clock signal for SONET/SDH PICs. • I2C controller—Monitors the status of router components. • Ejector levers—Control the locking system that secures the FEB in the chassis.
Routing Engine The Routing Engine installs into a slot in the FEB at the rear of the chassis. The Routing Engine is field-replaceable, but you must power down the router before removing it from the chassis. Packet forwarding halts until the Routing Engine is replaced and the router is powered on. For replacement instructions, see “Replace the Routing Engine” on page 115.
Craft Interface For specific information about Routing Engine components (for example, the capacity of the hard drive), issue the show chassis routing-engine command.
Craft Interface For information about the elements on the craft interface, see the following sections: • Alarm LEDs and Lamp Test Button on page 15 • Routing Engine Interface Ports and Status Indicators on page 15 • PIC Offline Buttons on page 16 Alarm LEDs and Lamp Test Button Two large alarm LEDs are located at the top of the craft interface. The circular red LED lights to indicate a critical condition that can result in a system shutdown.
Power Supplies • • CONSOLE—Connects the Routing Engine to a system console through an RS-232 (EIA-232) serial cable. AUX/MODEM— Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable. For information about the pinouts for the connectors, see “Cable Connector Pinouts” on page 171. PIC Offline Buttons An offline button for each PIC is located below the PIC slot along the bottom edge of the craft interface (see Figure 7).
Power Supplies After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 60 seconds before turning it off. If the router is completely powered down when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power down the router again, first issue the CLI request system halt command.
Power Supplies Table 5: Electrical Specifications for AC Power Supply Description Specification Maximum power output 800 W AC input voltage Nominal range: 100–240 VAC Operating range: 100–264 VAC AC input line frequency 47 – 63 Hz AC input current rating 8–4A Output voltages +1.5 V, +2.5 V, +3.3 V, +5.0 V, +12 V, +12 V DC Power Supply A DC-powered router has two load-sharing DC power supplies, located at the bottom rear of the chassis, as shown in Figure 3.
Fan Tray Description Specification Input DC current rating 13.5 A @ –48 V Output voltages +1.5 V, +2.5 V, +3.3 V, +5.0 V, +12 V, +12 V The DC power supplies are marked –48 VDC. This is the nominal voltage associated with the battery circuit. Any higher voltages are to be associated only with float voltages for the charging function. Power Supply LEDs and Self-test Button Table 7 describes the LED on both AC and DC power supplies.
Cable Management System The fan tray is hot-removable and hot-insertable, as described in “Field-Replaceable Units (FRUs)” on page 3. For instructions on replacing it, see “Replace the Fan Tray” on page 82. Do not remove the fan tray for more than a about one minute while the router is operating. The fans are the sole source of cooling, and the router can overheat when they are absent.
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.
Routing Engine Software Components • SNMP and MIB II Processes on page 26 • Management Process on page 27 • Routing Engine Kernel on page 27 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. It consolidates the routing information learned from all routing protocols into common routing tables.
Routing Engine Software Components • • • RIP—Routing Information Protocol, version 2, is an IGP for IP networks based on the Bellman-Ford algorithm. RIP is a distance-vector protocol. RIP dynamically routes packets between a subscriber and a service provider without the subscriber having to configure BGP or to participate in the service provider’s IGP discovery process.
Routing Engine Software Components IPv6 Routing Protocols The JUNOS Internet software implements full IP routing functionality, providing support for IP version 6 (IPv6). The routing protocols are fully interoperable with existing IP routing protocols and provide the scale and control necessary for the Internet core.
Routing Engine Software Components In the multicast routing table, the routing protocol process uses traffic flow and other parameters specified by the multicast routing protocol algorithms to select active routes. • MPLS routing table—Stores MPLS label information. For unicast routes, the routing protocol process determines active routes by choosing the most preferred route, which is the route with the lowest preference value.
Routing Engine Software Components VPNs The JUNOS software supports several types of VPNs: • • • • Layer 2 VPNs—A Layer 2 VPN links a set of sites sharing common routing information, and whose connectivity is controlled by a collection of policies. A Layer 2 VPN is not aware of routes within a customer’s network. It simply provides private links between a customer’s sites over the service provider’s existing public Internet backbone.
Tools for Monitoring the Software Management Process The management process starts all the other JUNOS software processes and the CLI when the router boots. It monitors the running JUNOS processes and makes all reasonable attempts to restart any process that terminates. Routing Engine Kernel The Routing Engine kernel provides the underlying infrastructure for all JUNOS software processes.
Software Upgrades Software Upgrades The router is delivered with the JUNOS Internet software preinstalled. To upgrade the software, you use CLI commands to copy a set of software images over the network to memory storage on the Routing Engine. The JUNOS Internet software set consists of several images provided in individual packages or as a bundle. You normally upgrade all packages simultaneously.
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.
Packet Forwarding Engine Architecture • • • 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.
Routing Engine Architecture Figure 13: Packet Forwarding Engine Components and Data Flow PIC Packet in Midplane Routing Engine FEB Controller Distributed Buffer Manager Internet Processor II I/O Manager Packet out Controller Distributed Buffer Manager 1335 PIC = ASIC 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.
Routing Engine Architecture Figure 14: Routing Engine Architecture JUNOS software System management processes Routing protocols Control functions Kernel System processes Operating system 1164 Intel-based PCI platform 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.
Routing Engine Architecture • Monitoring efficiency and flexibility—The router supports functions such as alarm handling and packet counting on every port, without degrading packet-forwarding performance. The Routing Engine constructs and maintains one or more routing tables. From the routing tables, the Routing Engine derives a table of active routes, called the forwarding table, which is then copied into the Packet Forwarding Engine.

Chapter 5 Prepare for Router Installation This chapter describes how to prepare your site for installation of the M5 and M10 Internet routers.
Rack Requirements • A 600-mm rack as defined in the four-part Equipment Engineering (EE); European telecommunications standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute (http://www.etsi.org). The horizontal spacing between the rails in a rack that complies with this standard are usually wider than the router’s mounting ears, which measure 19 in. (48.3 cm) from outer edge to outer edge.
Rack Requirements Figure 16: Typical Center-Mount Rack 19 in. (48.3 cm) Mounting rails 7 ft (2.13 m) 1011 Floor bolts Spacing of Mounting Holes The holes in the mounting brackets are spaced at 2 U (3.5 in. or 8.89 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.
Router Environmental Tolerances Clearance Requirements for Airflow and Hardware Maintenance When planning the installation site, you need to allow sufficient clearance around the rack (see Figure 17): • For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allowing at least 6 in. (15.
Fire Safety Requirements Description Tolerance Temperature Normal operation ensured in temperature range of 32° F to 104° F (0° C to 40° C) Seismic Designed to meet Bellcore Zone 4 earthquake requirements Install the router only in restricted areas, such as dedicated equipment rooms and equipment closets, in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.
Power Guidelines, Requirements, and Specifications In addition, in minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals. Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged. To keep warranties effective, do not use a dry chemical fire extinguisher to control a fire at or near a Juniper Networks router.
Power Guidelines, Requirements, and Specifications Site Electrical Wiring Guidelines When planning the electrical wiring at your site, consider the factors discussed in the following sections. Distance Limitations for Signaling Improperly installed wires can emit radio interference. In addition, the potential for damage from lightning strikes increases if wires exceed recommended distances, or if wires pass between buildings.
Power Guidelines, Requirements, and Specifications Table 9: Component Power Requirements Power Requirement (Watts) Power Requirement (Amps) Base system (all components except PICs, with fans running at normal speed) 188 (approximate) 4 A/48 V (approximate) Fans running at full speed (additional power required) 40 (approximate) 0.833 A/48 V Routing Engine 17 0.2 A/48 V FEB 50 1.
Power Guidelines, Requirements, and Specifications If you plan to operate a maximally configured DC-powered router, we recommend that you provision at least 13.5 A @ 48 VDC and use a facility circuit breaker rated for 20 A minimum. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure, and allows the router to function at full capacity using one power supply.
Power Guidelines, Requirements, and Specifications Australia Europe Italy Japan North America UK 1013 Figure 18: AC Plug Types For information about the AC power supply, including electrical specifications and a description of components, see “AC Power Supply” on page 17. For instructions on connecting the power cord during initial installation, see “Connect Power to an AC-Powered Router” on page 65.
Power Guidelines, Requirements, and Specifications For field-wiring connections, use copper conductors only. For other electrical safety information, see “Electrical Safety Guidelines and Warnings” on page 135. Figure 19 shows how to attach the grounding and power cables. The grounding cable attaches to one of the grounding points on the upper edge of the router rear panel. The accessory box shipped with the router contains the lug used to secure the grounding cable the grounding point.
Network Cable Specifications and Guidelines connecting the DC power and grounding cables during initial installation, see “Connect Power to a DC-Powered Router” on page 66. For instructions on replacing the cables on an operating router, see “Disconnect and Connect DC Power” on page 108. Power cords and cables must not block access to router components or drape where people could trip on them.
Network Cable Specifications and Guidelines Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances. It is consequently more expensive. For information about the maximum transmission distance and supported wavelength range for the types of single-mode and multimode fiber-optic cable used by PICs on the M5 and M10 routers, see the M5 and M10 Internet Routers PIC Guide.
Network Cable Specifications and Guidelines When you calculate the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate at the worst-case levels.
Network Cable Specifications and Guidelines The following example uses the estimated values in Table 12 to calculate link loss (LL) for a 2 km-long multimode link with a power budget (PB) of 13 dB: • Fiber attenuation for 2 km @ 1.0 dB/km= 2 dB • Loss for five connectors @ 0.5 dB per connector = 5(0.5 dB) = 2.5 dB • Loss for two splices @ 0.5 dB per splice =2(0.5 dB) = 1 dB • Higher-order loss = 0.
Site Preparation Checklist the power to bring it within the allowable range; for short lengths of fiber, with fiber and connector loss close to zero, an attenuator of 5 to 10 dB should be sufficient. For specifications of minimum and maximum input level (receiver sensitivity and receiver saturation) and minimum and maximum output level (average launch power) for the SONET/SDH PICs supported on the M5 and M10 routers, see the M5 and M10 Internet Routers PIC Guide.
Site Preparation Checklist Item or Task Performed By Date Notes Select the type of rack. Plan rack location, including required space clearances. Secure rack to floor and building structure. Acquire cables and connectors. Locate sites for connection of system grounding. Calculate power budget and power margin.

Chapter 6 Unpack the Router This chapter explains how to unpack the router and verify the parts received. Before beginning, prepare the installation site as described in “Prepare for Router Installation” on page 37 and review the safety information in “Safety and Regulatory Compliance Information” on page 129, especially “General Safety Guidelines and Warnings” on page 131 and “Installation Safety Guidelines and Warnings” on page 146.
Unpack the Router 2. Position the carton so that the arrows are pointing up. 3. Using a utility knife, cut through the sealing tape on the top seam of the carton. Open the top flaps of the carton. 4. Remove the accessory box and packing material from the top of the router. 5. Open the accessory box and verify the contents against the parts inventory on the label attached to the box. 6. Remove the router from the shipping carton. 7.
Choose Front or Center Mounting Component Quantity Front-mounting shelf 1 Mounting ears 2 PIC and PIC blank Up to 4 on an M5 router Up to 8 on an M10 router Power supply 2 Routing Engine 1 Choose Front or Center Mounting You can mount the router into either a center-mount rack, or into front-mount rack, four-post rack, or cabinet. In general, a center-mount rack is preferable, because the more even distribution of weight in the center-mount rack provides greater stability.
Choose Front or Center Mounting 58 M5 and M10 Internet Routers Hardware Guide
Chapter 7 Install the Router Because the router weighs between 57 lb (25.8 kg) and about 61 lb (27.6 kg) for the M5 router or 67 lb (29.5 kg) for the M10 router, using a mechanical lift to install it is recommended. If you do not use a mechanical lift, installing the chassis safely requires two people to lift and an additional person to insert the mounting screws.
Install the Chassis into the Rack • • • Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure. For details, see “Rack Requirements” on page 37. Read the information in “Installation Safety Guidelines and Warnings” on page 146, with particular attention to “Chassis Lifting Guidelines” on page 146. Remove the router from the shipping carton, as described in “Unpack the Router” on page 55.
Chapter 8 Connect the Router and Perform Initial Configuration After installing the router into the rack as described in “Initial Installation” on page 35, complete the installation by connecting management and alarm devices, PICs, and power cables.
Connect the Router to Management Devices Figure 21: Routing Engine Management Ports R Red alarm LED Lamp test button Yellow alarm LED Link status LED PIC0/3 PIC0/2 PIC0/1 PIC0/0 PIC1/3 PIC1/2 PIC1/1 PIC1/0 PIC online/offline buttons 1336 Activity status LED Routing Engine ports To connect external devices to the Routing Engine management ports, perform the procedures described in the following sections: • Connect to a Network for Out-of-Band Management on page 62 • Connect to a Managemen
Connect PIC Cables 1063 Figure 22: Routing Engine Ethernet Cable Connector Connect to a Management Console or Auxiliary Device To use a system console to configure and manage the Routing Engine, connect it to the CONSOLE port on the craft interface. To use a laptop, modem, or other auxiliary device, connect it to the appropriate AUX/MODEM port on the craft interface. Both ports accept an RS-232 (EIA-232) serial cable with DB-9/DB-9 connectors. One such cable is provided with the router.
Connect PIC Cables 2. If the PIC cable connector port is covered by a rubber safety plug, remove the plug. Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate.

Troubleshoot Packet Forwarding Engine Components Juniper Networks Technical Assistance Center If you need assistance during troubleshooting, you can contact the Juniper Networks Technical Assistance Center (JTAC) by e-mail or telephone. See “How to Request Support” on page xix.
Troubleshoot the Power System Troubleshoot the FEB If the FEB fails, the forwarding and routing functions of the router halt immediately and do not resume until the FEB failure has been corrected. To troubleshoot an FEB, follow these guidelines: • • Make sure the FEB is properly seated in the midplane. Use a Phillips screwdriver to ensure that the screws at the top of the FEB are securely tightened. Check the alarm LEDs on the craft interface.
Troubleshoot the Power System LED on Both Supplies Is Off If the LED is off on both power supply faceplates, either someone has switched off power to the router or the system temperature has exceeded the acceptable maximum. In the latter case, the Routing Engine shuts down both power supplies. There is no power to the router, so no LED is lit, including the alarm LEDs on the craft interface. Excessive system temperature is almost always caused by excessive environmental temperature.
