M320 Router Description on page 3

M320 Router Description

The M320 Multiservice Edge Router is a high-density edge aggregation, routing, and service creation platform that builds on Juniper Networks service-built edge design. Constructed with separations between the control plane, forwarding plane, and services plane, the router supports multiple services on a single platform. The Junos OS runs on a control subsystem with dedicated hardware, ensuring that control functions are performed without affecting the forwarding subsystem. Forwarding and packet processing operations in the router are performed by dedicated programmable ASICs that enable the router to achieve data forwarding rates that match current fiber-optic capacity. This design eliminates processing and traffic bottlenecks, permitting the router to achieve high performance.

The router can be deployed in core, peering,and datacenter applications, butis optimized for dense edge aggregation and service creation. The M320 router can provide a single point of edge aggregation for thousands of customers over any access type, including ATM, Frame Relay, Ethernet, and TDM, at any speed from DS0 up to OC192/STM64 and 10-Gigabit Ethernet.

Documentation

The router is a half-rack chassis that supports up to eight Flexible PIC Concentrators (FPCs) providing up to 64 SONET/SDH OC48/STM16, 16 SONET/SDH OC192/STM64, or 160 Gigabit Ethernet ports for the router. In a standalone configuration, the Router's maximum aggregate throughput is 320 gigabits per second (Gbps), half duplex. The routersupports up to eight of these FPCs:

•

Type 1 FPCs—Rated at 4 Gbps full duplex, supports up to four PICs.

•

Type 2 FPCs—Rated at 16 Gbps full duplex, supports up to four PICs.

•

Type 3 FPCs—Rated at 20 Gbps full duplex, supports up to two PICs, including higher-speed PICs.

The router can operate with any FPC type in any slot. Type 1 FPCs and Type 2 FPCs each support four PICs, and Type 3 FPCs supports two PICs.

M320 Component Redundancy

A fully configured router is designed so that no single point of failure can cause the entire system to fail. Only a fully configured router provides complete redundancy. All other configurations provide partial redundancy. The following major hardware components are redundant:

•

Switch Interface Boards (SIBs)—A fully configured router has four SIBs. Each FPC has a dedicated ASICwith four high-speed links that connect to the SIBs (one link per SIB). In the event of a complete SIB failure, the traffic is forwarded across the remaining three planes with a slight degradation in performance. When the failed SIB is replaced, the router regains full forwarding capacity.

•

Host subsystem—The host subsystem consists of a RoutingEngine functioningtogether with a CB. To operate, each host subsystem requires a Routing Engine installed in an adjacent slot to the CB. The router can have one or two host subsystems. If two host subsystems are installed, one functions as the master and the other functions as the backup. If the master host subsystem (or either of its components) fails or is taken offline, the backup can take over as the master.

M320 Router Hardware Guide

For information about the effect of taking the host subsystem offline, see “Taking the M320 HostSubsystemOffline” onpage 160.For moreinformation about high availability features, see the Junos OS High Availability Configuration Guide.

•

Powersupplies—A router with a minimum of three AC power supplies or four DC power supplies is fully power redundant. In the AC configuration, all power supplies share the load evenly. In the DC configuration, two power supplies share the load to some of the components, and two other power supplies share the load to the remaining components. In both configurations, if one power supply fails, the remaining power supplies can provide full power to the router.

•

Cooling system—Thecooling system has redundant components, which are controlled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely.

The router chassis is a rigid sheet metal structure that houses all the other router components (see Figure 1 on page 7). The chassis measures 34.80 in. (88.4 cm) high,

17.43 in. (44.3 cm) wide, and 25.64 in. (65.1 cm) deep (from the front-mounting flanges to the rear of the chassis). The chassis canbe installed in many types of racks or cabinets. For more information, see Requirements Reference Example: M320 Cabinet Size and Clearance Requirements and “Rack Requirements for the M320 Router” on page 42

The chassis includes the following features (see Figure 1 on page 7, Figure 2 on page 8, and Figure 3 on page 9):

•

One pair of metal adjustable center-mounting brackets that can be attached to one of 11 positions on the side of the chassis. You can use the brackets for mounting the chassis in the rack or cabinet.

•

Two installation handles on the top to facilitate positioning the router in the rack. Do not use the handles to lift the router.

•

Two electrostatic discharge points (banana plug receptacles): one front and one rear.

CAUTION: Before removing or installing components of a router, attach

an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router.

M320 Flexible PIC Concentrator (FPC) Description

Up to eight Flexible PIC Concentrators (FPCs) install vertically in the front of the router (see Figure 5 on page 12). The FPC slots are numbered left to right from FPC0 to FPC7. Depending on the FPC type, an FPC has either two or four slots into which a PIC can be installed (see “M320 FPCs Supported” on page 14 for more information). An FPC can be installed into any FPC slot on the router, regardless of which PICs it contains.

If a slot is not occupied by an FPC, an FPC blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

Each FPC consists of the following components:

•

FPC card carrier, which includes the PIC slots.

•

One Packet Forwarding Engine consisting of Layer 2/Layer 3 Packet Processing ASICs, Switch Interface ASICs, Internet Processor ASICs, and an MMB, which includes the Queuing and Memory Interface ASICs.

•

Midplane connectors and power circuitry.

•

Processorsubsystem(PMB), which includes a288-MHz CPU,system controller, 256 MB of SDRAM, and two Fast Ethernet interfaces.

•

Two LEDs, located on the craft interface above the FPC, that display the status of the FPC. For more information about the FPC LEDs, see “M320 Craft Interface FPC LEDs and Online/Offline Buttons” on page 32.

•

FPC online/offline button, located on the craft interface above the FPC.

The Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. Each FPC contains a memory subsystem (MMB) that is managed by the Queuing and Memory Interface ASICs.

FPCs are hot-removable and hot-insertable, as described in “M320 FRU Description” on page 137. When you install an FPC into a functioning router, theRouting Enginedownloads the FPC software, the FPC runs its diagnostics, and the PICs, housed on the FPC, are enabled. Forwarding continues uninterrupted during this process. When you remove or install an FPC, packet forwarding is not affected. For FPC replacement instructions, see “Replacing an M320 FPC” on page 175.

M320 Host Subsystem Description

The host subsystem provides the routing and system management functions of the router. You can install one or two host subsystems on the router. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding Control Board (CB) and vice versa.

NOTE: We recommend that you install two host subsystems for redundant

protection. If you install only one host subsystem, we recommend that you install it in slot RE0.

Chapter 2: M320 Hardware Components

NOTE: Eachhost subsystemhas three LEDs that display its status.The LEDs

that report host module status(including Routing Engine status)are located in the middle of the craft interface rather than the Routing Engine faceplate. For more information about the host subsystem LEDs, see “M320 Craft Interface Host Subsystem LEDs” on page 30.

NOTE: For specific information about Routing Engine components (for example, the amount of DRAM), issue the show chassis routing-engine command.

NOTE: If two Routing Engines are installed, they must both be the same hardware model.

M320 Routing Engine Description

The Routing Engine runs the Junos operating system (OS). The software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the router, control the router interfaces, control some chassis components, and provide the interface for system management and user access to the router.

You can install one or two Routing Engines in the router. The Routing Engines install into the upperrear ofthe chassisin the slots labeled RE0 and RE1. Each RoutingEngine requires a CB to be installed in the adjacent slot. RE0 installs below CB0, and RE1 installs above

CB1. A Routing Engine does not power up if a CB is not present in the adjacent slot.

If two Routing Engines are installed, one functions as the master, and the other acts as the backup. If themaster Routing Engine fails or is removed,and the backup is configured appropriately, the backup can take over as the master. If the Routing Engines are configured for nonstop active routing, the backup Routing Engine automatically synchronizes its configuration and state with the master Routing Engine. Any update to the master Routing Engine state isreplicatedon thebackup Routing Engine. If the backup Routing Engine assumes mastership, packet forwarding continues through the router without interruption. For more information about nonstop active routing, see the Junos OS High Availability Configuration Guide.

The master Routing Engine (if nonstop active routing is configured) and the backup Routing Engine are hot-removable and hot-insertable. A nonredundant Routing Engine or master Routing Engine (if nonstop active routing is not configured) is hot-pluggable.

The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.

A condition that causes an LED to light also activates the corresponding alarm relay contact on the connector interface panel (CIP). The LED display on the craft interface reports the cause of the alarm.

To deactivate red and yellow alarms, press the button labeled ACO/LT (for “alarm cutoff/lamp test”), which is located to the left of the alarm LEDs. Deactivating an alarm turns off both LEDs and deactivates the device attached to the corresponding alarm relaycontact on the CIP. However, the LED displaycontinues to report the alarmmessage until you clear the condition that caused the alarm.

M320 Power System Description

The M320 router uses either AC or DC power supplies. The router is configurable with two,three, orfour AC powersupplies or two orfour DCpower supplies.The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the router components, depending on their voltage requirements.

All power supplies are hot-removable and hot-insertable. Each power supply is cooled by its own internal cooling system.

Documentation

• M320 Power Requirements on page 250

• Troubleshooting the M320 Power System on page 132

M320 AC Power Supply

In the AC power configuration, the router contains two to four load-sharing AC power supplies (see Figure 17 on page 34), which are located at the lower rear of the chassis in slots PEM0 through PEM3 (top to bottom). The router requires a minimum of two fully functional power supplies to operate.

To provide power redundancy, you can upgrade the number of AC power supplies from two to three or from three to four. Each AC power supply provides power to all components in the router, as opposed to the DC power configuration (see “M320 DC Power Supply” on page 34 for more information). Three AC power supplies provide full

CAUTION: Mixing AC and DC power supplies is not supported and prevents

the router from powering on.

Grounding the M320 Router on page 95•

power redundancy. If one power supply fails or is removed, the remaining power supplies instantly assume the entire electrical load.

NOTE: In a router with two power supplies (no power supply redundancy),

if one power supply fails or is shut down, the other power supply goes into a “check” state and does not operate even though it has not failed (this is because the router requires two power supplies to operate).

For AC power supply and power system electrical specifications, see “M320 AC Power Electrical Specifications” on page 252 and “M320 AC Power Cord Specifications” on page 253.

M320 DC Power Supply

In the DC power configuration, the router contains either two or four DC power supplies (see Figure 18 on page 35), located at the lower rear of the chassis in slots PEM0 through

PEM3 (top to bottom). You can upgrade your DC power supply from two to four power

supplies. The DC power suppliesin slotsPEM0 and PEM2,when both are installed, provide load-sharing and power to the FPCs in slots FPC3 through FPC7. The DC power supplies in slots PEM1 and PEM3, when both are installed, provide load-sharing and power to the FPCs in slots FPC0 through FPC2, SIBs, CBs, and Routing Engines. All DC power supplies provide power to the fan trays.

When fully configured with four DC power supplies, the DC power supplies provide full redundancy. The DC power supplies in slots PEM0 and PEM1 can provide full power to the router. Likewise, the DC power supplies in slots PEM2 and PEM3 can also provide full power. The DC power supply in PEM2 serves as the backup to the DC power supply in slot PEM0, and the DC power supply in PEM3 serves as the backup to the DC power supply in slot PEM1.

Connecting Power to an AC-Powered M320 Router on page 96•

Chapter 2: M320 Hardware Components

Each DC power supply has a single DC input (-48 VDC and return) that requires a dedicated60 A (–48 VDC) circuitbreaker.

M320 Fuses

The router uses fuses from the Cooper Bussman brand GMT series for the CB, SIBs, and FPCs. The fuses are located in the rear of the midplane behind the power supply in slot

PEM0. When the fuse for a component blows, the component stops functioning even

though it is installed correctly and the power supplies are providing power to the router. For more information, see “Troubleshooting the M320 Fuses” on page 133. For fuse replacement instructions, see “Replacing an M320 Fuse” on page 204.

The host subsystem monitors the temperature of the router components. When the router is operating normally, the fans function at lower than full speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing Engine shuts down some or all of the hardware components.

M320 Cable Management System Description

The cable management system (see Figure 20 on page 39) consists of a row of nine semicircular plastic bobbins mounted on the front of therouter below the FPC card cage. The PIC cables pass between the bobbins and into the tray, keeping the cables organized and securely in place. The curvature of the bobbins also helps maintain the proper bend radius for optical PIC cables.

You can pull the cable management system up and outward to lock it into the maintenance position. This allows you to access the lower fan tray and the front air filter.

Chapter 2: M320 Hardware Components

Figure 20: Cable Management System

The router; ships with an accessory box that contains four cable guards—two upper and two lower—that you can install on the front-mounting flanges of the chassis after you have mounted the chassis in a rack or cabinet. The cable guards protect the PIC and CIP cables from rubbing against the front edges of the chassis.

Included with your router shipment is a clear plastic cable cover that you can attach to slots in the cable guards without using tools. The cable cover prevents the PIC and CIP cables from being disturbed or snagged.

Rack Requirements for the M320 Router

The router can be installed in many types of racks, including four-post (telco) racks and open-frame racks. An example of an open-frame rack is shown in Figure 21 on page 43.

For open-frame racks, center-mounting is preferable to front-mounting because the more even distribution of weight provides greater stability.

The router is designed for installation ina 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org).

With the use of adapters, the router can fit into a 600-mm-wide rack or cabinet, 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). Use approved wing devices to narrow the opening between the rails.

The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 34.80 in. (88.4 cm) high, 25.64 in. (65.1 cm) deep, and

17.43 in. (44.3 cm) wide, excluding the front and rear cable management systems. The

Chapter 3: Preparing the Site for M320 Router Installation

outer edges of the mounting brackets extend the width to 19 in. (48.3 cm). The spacing of rails and adjacent racks must also allow for the clearances around the router and rack.

Two sets of holes are used in the mounting brackets and front-mount flanges to attach the chassis to a rack. The holes within each set are spaced at 2 U (3.5 in. or 8.9 cm) and 3 U (5.25 in. or 13.3 cm). The router; can be mounted in any rack that provides holes spaced at those distances.

The mounting holes for connecting the mounting brackets to the chassis are spaced

0.984 in. (25 mm) apart.

The chassis height of 34.80 in. (88.4 cm) is approximately 20 U. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association. You can stack two M320 routers in a rack that has at least 40 U (70 in. or 1.78 m) of usable vertical space.

The rack must be strong enough to support the weight of the fully configured router, up to 439 lb (199.6 kg). If you stack two fully configured routers in one rack, it must be capable of supporting about 878 lb (399.1 kg).

Figure 21: Typical Open-Frame Rack

M320 Router Hardware Guide

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.

Documentation

M320 Clearance Requirements on page 44•

• M320 Chassis Lifting Guidelines on page 216

M320 Clearance Requirements

When planning the installation site, you need to allow sufficient clearance around the rack (see Figure 22 on page 44):

•

For the cooling system to function properly, the airflow around the chassis must be unrestricted. “M320 Cooling System Description” on page 37 depicts the airflow in the router.

•

For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. We recommend that you allow at least 30 in. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the rack.

Figure 22: Chassis Dimensions and Clearance Requirements

The router has two adjustable center-mounting brackets that are initially attached to the mounting holes closest to the rear ofthe chassis. Youcan movethe pair of adjustable center-mounting brakcets to one of 11 positions on the side of the chassis. The mounting holes for connecting the mounting brackets to the chassis are spaced 0.984 in. (25 mm) apart.

M320 Router Hardware Guide

M320 Cabinet Size and Clearance Requirements

The minimum size enclosed cabinet that can accommodate the router is 600 mm wide and 800 mm deep. A cabinet larger than the minimum requirement provides better airflow and reduces the chance of overheating. To accommodate a single router, the cabinet must be at least 20 U (35 in. or 88.9 cm) high. If you provide adequate cooling air and airflow clearance, you can stack two routers in a cabinet that has at least 40 U (70 in. or 1.78 m) of usable vertical space.

The minimum front and rear clearance requirements depend on the mounting configuration you choose. The minimum total clearance inside the cabinet is 30.70 in. between the inside of the front door and the inside of the rear door. If you choose a front-mount installation, you must maintain clearance of 4.80 in. (122 mm) between the front-mounting flanges and the inside of the cabinet front door, and 25.90 in. (658 mm) betweenthe front-mountingflanges and the insideof thecabinet rear door. If you choose an adjustable-mount installation usingthe mounting brackets, the clearance requirements depend on where you install the mounting brackets.

Table 15 on page 46 provides the clearance requirements for each of the 11 mounting bracket positions on the side of the chassis (position 1 represents the mounting brackets installed closest to the front of the chassis; position 11 represents the mounting brackets installed closest to the rear of the chassis). The front clearance is measured between the front of the front rack rail and the inside of the cabinet front door. The rear clearance is measured between the front of the front rack rail and the inside of the cabinet rear door.

M320 Cabinet Airflow Requirements

When you mount the router in a cabinet, you must ensure that ventilation through the cabinet issufficient to prevent overheating. Following is alist of requirements to consider when planning for chassis cooling:

•

Ensure that the cool air supply youprovide through the cabinet canadequatelydissipate the thermaloutput of the router.“M320 Environmental Specifications” on page 247 lists the router's environmental specifications, including its operating temperature and thermal output.

•

Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without recirculating into the router. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust. For an illustration of chassis airflow, see “M320 Cooling System Description” on page 37.

•

Install the router as close as possible to the front of the cabinet so that the cable management system just clears the inside of the front door. This maximizes the clearance in the rear of the cabinet for critical airflow.

•

If you operate the router in an enclosed 800-mm cabinet, you must install a baffle on the inside of the rear door of the cabinet to prevent the router from overheating at elevated ambient temperatures. The baffle separates the cool air intake from the hot air exhaust in the rear of the cabinet (for baffle dimensions and location, see Figure 24 on page 48). We recommend that the baffle be made of soft foam with a depth of

2.25 in. (57 mm) so that it slightly touches the rear of the router when the rear cabinet door is closed.

•

Route and dress all cables to minimize the blockage of airflow to and from the chassis.

technician verify that the rack is strong enough to support the router's weight and is adequately supported at the installation site.

M320 Router Hardware Guide

To install the router using a lift (see Figure 31 on page 67):

1. Ensure that the rack is in its permanent location and is secured to the building. Ensure

that the installationsite allows adequate clearance for both airflow andmaintenance. For details, see “M320 Clearance Requirements” on page 44.

2. Load the Router onto the lift, making sure it rests securely on the lift platform.

CAUTION: Do not lift the router using the craft interface, installation

handle, or the handles on top of the chassis. Use these handles only to help position the router.

3. Using the lift, position the router in front of the rack or cabinet, centering it in front of

the mounting shelves.

4. Lift the chassis approximately 0.75 in. above the surface of the mounting shelves and

position it as close as possible to the shelves.

5. Carefully slide the router onto the mounting shelves so that the bottom of the chassis

and the mounting shelves overlap by approximately 2 inches.

6. With one person pulling on the installation handle from the rear of the rack or cabinet

while another person pushes on the front-mounting flanges, slide the router onto the mounting shelves until the mounting brackets or front-mounting flanges contact the rack rails or spacer bars (depending on your type of installation). The shelves ensure that theholes inthe mounting brackets and the front-mounting flanges of the chassis align with the holes in the rack rails.

7. Move the lift away from the rack.

8. If you are installing the router in a four-post rack or cabinet, install a mounting screw

and a cage nut into each of the holes aligned with the threaded holes in the spacer bars. If you are installing the router in an open-frame rack, install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.

9. Visually inspect the alignment of the router. If the router is installed properly in the

rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side and the router should be level.
