System Description

The M5 and M10 Internet routers provide high-speed interfaces for medium and large networks and network applications, such as those supported by Internet service providers (ISPs). Application-specific integrated circuits (ASICs), a definitive part of the router design, enable the router to forward data at the high speeds demanded by current network media.

The M5 router supports up to four Physical Interface Cards (PICs), and the M10 router supports up to eight PICs. Each PIC accepts a specific type of network media, providing up to 16 physical interface ports per system o n the M5 router and up to 32 ports per system on the M10 router. The router height of 5.25 in. (13.3 cm) enables stacked installation of 14 M5 or M10 routers in a single floor-to-ceiling rack, for increased port density per unit of floor space.

the following topics:

The router’s maximum aggregate throughput is 6.4 gigabits per second (Gbps), full duplex. The router provides very high throughput for any combination of PICs that does not exceed 3 Gbps for the M5 router or 6 Gbps for the M10 router. A combination that exceeds these numbersissupported,butconstitutes oversubscription.

The router architecture cleanly separates control operations from packet forwarding operations, which helps to eliminate processing and traffic bottlenecks. Control operations in the router are performed by the Routing Engine, which runs JUNOS Internet software to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management. Forwarding operations in the router are performed by the Packet Forwarding Engine, which consists of hardware, including ASICs, designed by Juniper Networks.

Field-Replaceable Units (FRUs)

Field-replaceable units (FRUs) are router components that can be replaced at the customer site. Replacing most FRUs requires minimal router downtime. The router uses the following types of FRUs:

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.

Safety Requirements, Warnings, and Guidelines

To avoid harm to yourself or the router as you install and maintain it, you need to follow the guidelines for working with and near electrical equipment, as well as the safety procedures for working environment, see “Prepare for Router Installation” on page 37.

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. (61 cm) deep. The chassis height of 5.25 in. (13.3 cm) enables stacked installation of 14 M5 and M10 routers in a single floor-to-ceiling rack. For more information, see “Rack Requirements” on page 37.

The two mounting ears (one on each side) extend the chassis width to 19 in. (48.3 cm) and enable installation into either a front-mount or a center-mount rack.

Figure 1, Figure 2, and Figure 3 show front and rear views of the router chassis.

Physical Interface Cards (PICs)

Physical Interface Cards (PICs) physically connect the router to network media. They are housed in Flexible PIC Concentrators (FPCs); for more information about FPCs, see “Fl exible PIC Concentrators (FPCs)” on page 10.

PICsreceiveincomingpacketsfromthenetwork 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 complete PIC specifications, see the M5 and M10 Internet Routers PIC Guide.

Some PICs, such as selected Gigabit Ethernet 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 “Field-Replaceable Units (FRUs)” on page 3. For SFP replacement instructions, see “Replace an S FP” on page

95. For information about PICs that use SFPs, see the M5 and M10 Internet Routers PIC Guide.

Up to four regular PICs install into an M5 router and up to eight regular PICs install into an M10 router, as shown in Figure 1 and Figure 2. The PIC slots on an M5 router and in the upper FPConanM10routerarenumberedfrom0/0 (zero/zero) through 0/3, right to left. The PIC slots in the lower FPC on an M10 router are numbered from 1/0 (one/zero) through 1/3,right to left. The slot number for a PIC appears next to its offline button on the craft interface (see “PIC Offline Buttons” on page 16). The number of ports on a PIC depends on the type of PIC.

• 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 P ICs h ave additional LEDs, often one per port. The meaning of the LED states differs for various PICs. For more information, see the M5 and M10 Internet Routers PIC Guide.

• Ejector lever—Controls the locking system that secures the PIC in the card cage.

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 9). On the M5 and M10 routers, each FPC is built in (cannot be removed from the chassis as on other M-series platforms) and corresponds to a horizontal row of PIC slots. The single FPC on the M5 router is numbered 0 (zero) and the two FPCs on the M10 router are numbered 0 and 1,topto bottom. Each FPC accommodates up to fourregularPICsoronequad-widePIC.

Forwarding Engine Board (FEB)

The Forwarding Engine Board (FEB) performs route lookup, filtering, and switching on incoming data packets, then directs outbound packets to the appropriate FPC for transmission to the network. It can process 40 million packets per second (Mpps).

The FEB installs into the midplane from the rear of the chassis, as shown in Figure 3. It weighs approximately 7 lb (3.2 kg). The FEB is field-replaceable, but you must power down the router before removing it from the chassis. Packet forwarding halts until the FEB is replaced, the router is powered on, and the Routing Engine finishes booting.

For FEB replacement instructions, see “Replace the FEB” on page 84.

The FEB communicates with the Routing Engine using a d edicated 100-Mbps Fast Ethernet link that transfers routing table data from the Routing Engine to the forwarding table in the Internet Processor II ASIC. The link is also used to transfer from the FEB to the Routing
