Chapter 2

Product Overview

The NetIron MLX Series router provides high-performance routing for service providers, metro topologies, and
Internet Exchange Points. This chapter provides an overview of Foundry’s NetIron MLX Series routers. It provides
the following information:

• Overview of the benefits the NetIron MLX Series router offers

• Network topologies in which a NetIron MLX Series router will be commonly deployed

• The NetIron MLX Series router hardware and how each major hardware component functions

• Software features that the NetIron MLX Series router supports

• The NetIron MLX Series router’s architecture, how it differs from other Layer 3 router architectures, and how
you will benefit from the differences

Product Overview

The NetIron MLX Series router provides the following benefits:

• The ability of the 10 Gigabit Ethernet ports to process both inbound and outbound user packets at a full
10Gbps, thereby delivering true wire-speed performance

• IPv4 routing with very large hardware-based forwarding table and powerful hardware-based ACL and rate
limiting functions

• IPv6 routing with a rich feature set including hardware-based forwarding, and dual-stack support

• High availability (redundancy) of the following NetIron MLX Series router critical components:

• Management modules

• Fans

• Power supplies

• Switch fabric module

Each of these components, along with the interface modules, is hot swappable, which means you can remove
and replace them while the NetIron MLX Series chassis is powered on and running.

• Completely separate data and control planes, which results in uncompromised switching performance,
increased reliability of both planes, and increased security of the control plane in the event of a Denial of
Service attack (DoS) on the data plane

• Distributed data and control planes, which results in uncompromised wire-speed performance for the data
plane and faster and more efficient performance of management functions for the control plane

December 2008 © 2008 Foundry Networks, Inc. 2-1

Foundry NetIron MLX Series Installation and Basic Configuration Guide

• A management (10BaseT/100BaseTX/1000BaseTX Ethernet) port that can provide connectivity to your
existing management network

• Increased amount of TCAM on the interface modules, which accommodates the processing of more software
functions such as those related to routing protocols

• Increased amounts of processor RAM on the management and interface modules, which allows larger default
table sizes for the MAC address table, the IP route table, and so on

• Airflow that circulates from the front to the back of the NetIron MLX Series router chassis, which directs hot air
from the chassis away from other racks of equipment rather than toward them

NetIron MLX Series Router Applications

The NetIron MLX Series router is commonly deployed in the following situations:

• Layer 2 metro networks

• MPLS Layer-3 VPN service provider networks supporting multi-VRFs and RFC 2547bis

• MPLS Layer-2 VPN service provider networks supporting both VPLS and VLL

module becomes unavailable, the redundant management module automatically takes over the system operation,
minimizing system downtime. For information about the redundancy feature, see the chapter titled "Using a
Redundant Management Module" in the "Foundry NetIron XMR/MLX Configuration Guide".

The NetIron MLX-32 chassis uses a different management module than any of the other Foundry Networks
products. You cannot use management modules designed for the NetIron MLX-32 in any of the other NetIron MLX
Series chassis or management modules in the NetIron MLX-32 chassis designed for the NetIron MLX-4, NetIron
MLX-8, or NetIron MLX-16.

You can install management modules in dedicated slots marked M1 and M2. By default, the system considers the
module installed in the slot marked M1 to be the active management module.

NOTE: The NetIron MLX Series management module is dedicated, which means that you must install it in the
NetIron MLX Series chassis only. If you attempt to install the NetIron MLX Series management module in another
Foundry chassis or a management module intended for another Foundry chassis in the NetIron MLX Series
chassis, the module will not boot up to become active.

Additionally, the NetIron MLX-32 chassis uses a different management module than any of the other NetIron MLX
Series chassis. You cannot use management modules designed for the NetIron MLX-32 in any other Foundry
device, because it will not function properly.

A management module is hot swappable, which allows you to remove and replace it without powering down the
system.

Figure 2.5 shows the management module’s front panel.

Figure 2.5 Management Module Front Panel

The front panel includes the following control features:

• Two PCMCIA slots

• A Console port

• A 10/100/1000 Ethernet port

• Six LEDs

PCMCIA Slots

The PCMCIA slots support a flash PC card. The flash PC card provides storage space in addition to the system’s
flash memory. A flash PC card can store system files, including Boot images, startup configuration files, running
configuration files, and so on. As a result, you can perform system management tasks, such as copying files
between flash PC cards, copying files between a flash PC card and flash memory, and so on.

Console Port

The Console port is a standard DB-9 serial connector through which you can attach a PC or terminal to configure
the NetIron MLX Series system using the CLI.

This port interfaces the control plane only and not the data plane.

10/100/1000 Ethernet Port

The front panel includes a 10BaseT/100BaseTX/1000BaseTX auto-sensing, auto-negotiating Ethernet port. This
port has an RJ-45 unshielded twisted pair (UTP) connector.

Typical uses of this port include but are not limited to the following:

• Connecting a PC through which you can access the system through a Telnet or SSHv2 connection and

2-8 © 2008 Foundry Networks, Inc. December 2008

Product Overview

configure, monitor, and manage the NetIron MLX Series system.

• Connecting to the 10BaseT/100BaseTX/1000BaseTX port of a switch or router for connectivity to your
existing management network. You can then access the NetIron MLX Series system and configure, monitor,
and manage the system from a management station.

NOTE: The existing management network into which you can connect the 10/100/1000 Ethernet port must be
separate and isolated from the network over which user packets are switched and routed. For information about
the management port’s functionality, see “Understanding How the Management Port Functions” on page 4-5.

For information about connecting a PC and a switch to the 10/100/1000 Ethernet port, see “Attaching a
Management Station” on page 3-49.

This port interfaces the control plane only and not the data plane.

The POS Interface Modules support the following timing configurations:

• Internal Timing – This option uses the internal statum 3 clock. This is the default clocking configuration.

• Loop TIming – This option receives timing from the line

• Line Timing – This interface receives timing from the line and is used to clock all ports on the same interface
module but not for the entire chassis.

• External (BITS) Timing – This option allows timing to be provided by a central office BITS system. Each POS
interface module has 4 RJ-48C ports for connection to the external BITS system. The two input ports (labeled
IN) are for receiving clocking. The two output ports (labeled OUT) provide clocking to another POS Interface
module.

Configuration of the internal and external clocking and timing options are described in the chapter titled "Using
Packet Over SONET Modules" in the Foundry NetIron XMR/MLX Configuration Guide.

Foundry NetIron MLX Series Installation and Basic Configuration Guide

Power Supplies

The NetIron MLX Series routers support the following power supply options:

• NetIron MLX-4: Accommodates three power supplies (AC or DC) with one required and two redundant. It is
shipped with one power supply. You must purchase one or two additional power supplies if you want your
NetIron MLX-4 equipped for redundancy.

• NetIron MLX-8: Accommodates four power supplies (AC or DC) with two required and two redundant.
Because power is supplied over a common power bus, any power supply purchased in addition to the two
required will provide backup for any supply that fails. Equipping a NetIron MLX-8 with two additional power
supplies provides full redundancy for both of the required power supplies.

• NetIron MLX-16: Accommodates eight power supplies (AC or DC) with four required and four redundant.
Because power is supplied over a common power bus, any power supply purchased in addition to the four
required will provide backup for any supply that fails. Equipping a NetIron MLX-16 with four additional power
supplies provides full redundancy for all of the required power supplies.

• NetIron MLX-32: Accommodates eight power supplies. Power supplies available include: 2100W AC, 2400W
AC, and 2400W DC. The redundancy configuration is as follows:

• If 2100W AC power supplies are used, then five are required and three are redundant. This is for 200-240

volts AC only.

• If 2400W AC or 2400W DC are used, then four are required and four are redundant. This is for 200-240

volts AC only.

• If 2100W and 2400W power supplies (AC or DC) are used in combination, then five are required and

three are redundant.

Because power is supplied over a common power bus, any power supply purchased in addition to the four or
five required provides backup for any supply that fails.

NOTE: The 2400W AC and DC power supplies for the NetIron MLX-32 are new parts and will be released
shortly. Please check with Foundry Networks for availability of these parts.

NOTE: Only the NetIron MLX-8 and the NetIron MLX-16 power supplies are interchangeable with each other.
The NetIron MLX-4 and NetIron MLX-32 power supplies are not interchangeable with any other chassis.

For power supply specifications, see “Power Specifications” on page 8-1.

In the NetIron MLX-8, NetIron MLX-16 and NetIron MLX-32, you install the power supplies (AC or DC) in the slots
along the bottom of the chassis. In the NetIron MLX-4, the power supplies (AC or DC) are installed in slots in the
rear of the chassis. The installed power supplies provide power to all chassis components, sharing the workload
equally and reporting their status to the management module. If the management module detects that one of
these power supplies has failed or overheated, the management module will redistribute the failed power supply’s
workload to the remaining power supplies.

Each power supply has three LEDs on its faceplate that provide status for the input power, output power and
notification of alarms sent. If the input power and output power LEDs are on (a steady green), the power supply is
providing power to the chassis components. For more information about operation of the power supply LEDs, see
the AC and DC power supply sections in Table 3.5 on page 3-51. The power supplies are hot swappable, which
means you can remove and replace them without powering down the system. For information about replacing a
power supply, see “Replacing a Power Supply” on page 6-10.

NOTE: After a power supply is removed from a NetIron MLX Series chassis, the software determines if there is
enough power to power-on the interface modules. If it determines that there isn’t enough power, some interface
modules will be powered off.

WARNING: The power supplies are hot swappable, which means they can be removed and replaced while the
NetIron MLX Series chassis is powered on and running. However, Foundry recommends that you disconnect a
power supply from its power source before removing and replacing the supply. The NetIron MLX-4, -8, or -16 chas-

sis can be running while a power supply is being removed and replaced, but the power supply itself should not be
connected to a power source. Otherwise, you could be injured or the power supply or other parts of the device
could be damaged. (In the NetIron MLX-32 chassis, you cannot unlatch and remove a power supply without first
releasing the cord retainer and removing the power cord.)

Built-in Mounting Brackets

The NetIron MLX-4 and NetIron MLX-8 chassis has built-in mounting brackets that enable you to front-mount the
chassis in a standard 19-inch (EIA310-D) rack. For instructions about using the built-in mounting brackets to
mount the device in a rack, see “Installing a NetIron MLX Series Router”.

Alternatively, you can use a mid-mount kit (ordered separately) to center-mount the NetIron MLX chassis using
two L-shaped mounting brackets. The mid-mount kit comes with instructions for installing the mounting brackets
and mounting the device in a rack.

Contact Foundry Networks for information about mid-mount kits.

Cooling System

The cooling system of the NetIron MLX Series is configured as described:

• NetIron MLX-4: Is equipped with a fan module containing two 4-speed fans and two fan controllers to support
redundancy.

• NetIron MLX-8: Is equipped with a fan module containing four 4-speed fans and four fan controllers to support
redundancy.

• NetIron MLX-16: Is equipped with three fan assemblies. The fan tray located in the lower front of the chassis
contains six 4-speed fans. There are two fan assemblies located in the rear of the chassis. Each of these
contain a 4-speed fan that pulls air through the chassis. The NetIron MLX-16 is equipped with eight fan
controllers to support redundancy.

• NetIron MLX-32: Is equipped with ten fan assemblies in the rear of the chassis. Each of these contains a 4­speed fan that pulls air through the chassis. The fan trays support four settings, 50%, 75%, 88%, and 100%,
as the normal fan speeds, and the management module sets all system fans to one of these speeds.

As shown in Figure 2.13 and Figure 2.14, the fans are located in the front of the NetIron MLX-4 and NetIron MLX­8 chassis. Figure 2.15 and Figure 2.16 show the front and rear locations of the fans on the NetIron MLX-16. Figure

2.17 shows the locations of all 10 fans at the rear of the NetIron MLX-32 chassis.

Upon system startup, the fans in the NetIron MLX Series router operate at high speed, then the management
module lowers the fan speed to low speed.

By default, the NetIron MLX Series router polls the temperature sensor on each module every 60 seconds to get a
temperature reading. Depending on the temperature readings for the modules, the system can do the following:

• Leave the fan speed as is

• Increase the fan speed

• Decrease the fan speed

• Shut down a module to prevent damage

If the temperature of a module exceeds specified high temperature thresholds, the system generates a Syslog
message and SNMP trap. The system can also shut the module down if the temperature exceeds the highest
threshold.

You can change default low and high temperature thresholds for modules and fan speeds.

The NetIron MLX Series chassis ships with all fan components fully installed. However, Foundry recommends that
you replace the air filters quarterly. For information about replacing the air filter and if necessary, other fan
components, see “Maintaining a NetIron MLX Series Router” on page 6-1. The fan components are hot
swappable, which means you can remove and replace them without powering down the system.

CAUTION: To avoid overheating of the NetIron MLX Series chassis, remove only one fan at a time. Failure to
have sufficient air flow within the chassis for an extended period of time may cause damage to the system. Do not
remove all fans from the chassis at one time.

December 2008 © 2008 Foundry Networks, Inc. 3-1

Foundry NetIron MLX Series Installation and Basic Configuration Guide

Power Precautions

CAUTION: Use a separate branch circuit for each AC power cord, which provides redundancy in case one of the

circuits fails.

WARNING: Make sure to choose the appropriate circuit device, depending on the number of AC power supplies
installed in the chassis.

WARNING: Disconnect the power cord from all power sources to completely remove power from the device.

WARNING: Make sure that the power source circuits are properly grounded, then use the power cord supplied

with the device to connect it to the power source.

WARNING: If the installation requires a different power cord than the one supplied with the device, make sure
you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your
country. The mark is your assurance that the power cord can be used safely with the device.

WARNING: Make sure the rack or cabinet housing the device is adequately secured to prevent it from becoming
unstable or falling over.

WARNING: Mount the devices you install in a rack or cabinet as low as possible. Place the heaviest device at the
bottom and progressively place lighter devices above.

CAUTION: Ensure that the device does not overload the power circuits, wiring, and over-current protection. To
determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed
on the same circuit as the device. Compare this total with the rating limit for the circuit. The maximum ampere rat­ings are usually printed on the devices near the input power connectors.

CAUTION: NetIron MLX -4, -8, -16, and -32 devices with DC power sources are intended for installation in
restricted access areas only. A restricted access area is where access can be gained only by service personnel
through the use of a special tool, lock and key, or other means of security, and is controlled by the authority
responsible for the location.

CAUTION: All devices with AC power sources (NetIron MLX-32 only) are intended for installation in restricted
access areas only. A restricted access area is a location where access can be gained only by service personnel
through the use of a special tool, lock and key, or other means of security.

CAUTION: For a DC system, the gauge of wire will be determined by the power source as well as the power
supply draw (see Table 3.1). Use a grounding wire of at least 6 American Wire Gauge (AWG). The AWG wire
should be attached to an agency-approved crimp connector (provided on the NetIron MLX Series chassis),
crimped with the proper tool. The single crimp connector should allow for securement to both ground screws on
the enclosure. For NetIron MLX -8 and -4, use a grounding wire of at least 6 AWG. For the grounding lug, use UL­listed Panduit crimp connector, P/N LCD6-10A, and two 10-32, PPH screws to secure the crimp connector to
chassis. The grounding position is located on the side of chassis adjacent ground symbol.

Chassis Lifting Guidelines for NetIron MLX-4 Routers

WARNING: A fully-populated NetIron MLX-4, chassis is heavy. TWO OR MORE PEOPLE ARE REQUIRED

WHEN LIFTING, HANDLING, OR MOUNTING THESE DEVICES.

Follow these guidelines for lifting and moving a NetIron MLX-4 chassis:

• Before lifting or moving the chassis, disconnect all external cables.

Installing a NetIron MLX-4 Chassis in a Rack

This section describes the following tasks:

• “Preparing to Mount a NetIron MLX-4 Chassis in a Rack”

• “Removing NetIron MLX-4 Extra Shipment Screws”

• “Mounting a NetIron MLX-4 Chassis in a Rack”

• “Removing the Slot Blanks”

Preparing to Mount a NetIron MLX-4 Chassis in a Rack

Because of the weight of a fully loaded NetIron MLX-4 chassis, Foundry recommends mounting a chassis in a
rack before installing the modules and AC power supplies if necessary.

In a standard 19-inch (EIA310-D) rack, you can install up to ten NetIron MLX-4 chassis.

For each NetIron MLX-4 chassis that you install in a rack, you must provide four standard #12-24 pan-head screws
with which to mount and secure the chassis. Before performing this task, you should have an assembled rack and
a #2 Phillips-head screwdriver.

Removing NetIron MLX-4 Extra Shipment Screws

The NetIron MLX-4 ships with two extra screws installed in the right side of the chassis. These screws secure the
fan tray, protecting it from damage during shipment. You must remove these screws before installing the chassis.
Figure 3.1 shows the location of the screws.

To perform this task, you need a #2 Phillips-head screwdriver.

Figure 3.1 Removing the Extra Screws Used for Shipment

Mounting a NetIron MLX-4 Chassis in a Rack

To mount a NetIron MLX-4 chassis in a rack, do the following:

1. Determine the position of each chassis in the rack, for example, a chassis with the fewest modules on top, a
chassis with more modules than the top chassis in the middle, and a fully populated chassis on the bottom.

December 2008 © 2008 Foundry Networks, Inc. 3-5

Standard
19-inch
Rack

2. Position the four screws for each chassis according to the spacings of the keyhole slots on the mounting
brackets as shown in Figure 3.2. Do not secure the screws completely; leave approximately 1/4 inch of
clearance between the back of the screw head and the rack.

Figure 3.2 Positioning the Screws in a Rack

3. Starting with the chassis that you want to mount in the lowest position in the rack, mount the chassis in the
rack as shown in Figure 3.3. With two or more people lifting the chassis, slip the wide portion of each keyhole
slot over the corresponding screw in the rack.

Figure 3.3 Mounting the NetIron MLX-4 or NetIron MLX-8 Chassis in a Rack

4. Slide the chassis down so that the screw heads are in the narrow portion of the keyhole slots.

5. Tighten the screws to secure the chassis in place.

3-6 © 2008 Foundry Networks, Inc. December 2008

Installing a NetIron MLX Series Router

NOTE: To provide better grounding of the chassis to the rack, attach the chassis to the rack using star washers.

Additionally, if any single hole grounding lugs are used star washers shall be used as a means to prevent rotation
of the lug.

6. Repeat Step 3 through Step 5 to mount each subsequent chassis in the same rack.

Removing the Slot Blanks

The NetIron MLX-4 chassis ships with slot blanks installed in all module slots. The slot blank covers a slot that
does not currently have a module installed in it, ensuring proper airflow within the chassis. If you plan to install a
module in a particular slot, you must remove the slot blank.

CAUTION: If you do not install a module in a slot, you must keep the slot blank in place. If you run the chassis
with an uncovered slot, the system may overheat. Tighten the screws that secure the slot blanks so that they
remain in place when removing adjacent panels or modules.

Although the slot blanks are different in size, the procedure for removing them from the NetIron MLX-4 chassis is
the same. Therefore, this section provides one procedure that applies to all slot blanks.

You will need a flat-head screwdriver to perform this task.

To remove a slot blank, do the following:

1. Loosen the screws on either end of the slot blank by hand or with a flat-head screwdriver.

2. Pull the slot blank out of the chassis, and store it in a safe place for future use.

Installing NetIron MLX-4 Modules

This section provides one procedure that applies to all modules. The sequence for installing more than one
module is important to ensure proper fit. The recommended sequence for the NetIron MLX-4 chassis is to start
with the lowest row, moving upwards, from right-to-left.

WARNING: The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building
or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be
metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4)
and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection
in order to connect these interfaces metallically to OSP wiring.

NOTE: The NetIron MLX Series modules are dedicated, which means that you must install them in the NetIron
MLX Series chassis only. For example, if you attempt to install the NetIron MLX Series management module in
another Foundry chassis or a management module intended for another Foundry chassis in the NetIron MLX
Series chassis, the chassis and module will not function properly.

Table 3.2 provides the chassis slot number(s) into which you must install the modules. Markings for the chassis
slots appear at the base of the slots.

The NetIron MLX-4 chassis ships with the required switch fabric modules installed.

Module” in the "Foundry NetIron XMR/MLX Configuration Guide" for information about how the redundant module
works, optional software configurations that you can perform, and how to manage the redundancy feature.

Before installing a module in the NetIron MLX-4 chassis, have the following on hand:

• An ESD wrist strap with a plug for connection to the ESD connector on the NetIron MLX-4 chassis.

WARNING: For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.

• A large flat-head screwdriver.

To install a module in the NetIron MLX-4 chassis, do the following:

1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector on the chassis
front.

2. Remove the module from its packaging.

3. With the ejectors in the outward position, insert the module into the appropriate chassis slot and slide the card
along the card guide until the ejectors on either side of the module move close to the module front panel.

Figure 3.4 Installing a Module in a NetIron MLX-4 Chassis

NOTE: When inserting the module into the chassis, make sure that the faceplate doesn’t overlap with the

faceplate of an adjacent Interface module.

4. Push the ejectors in until they are flush with the module front panel. This action will fully seat the module in
the backplane. Modules have a snug fit for maximum EMI protection.

NOTE: The installation instructions for installing modules shown in the following illustrations are exactly the
same for interface, management, and switch fabric modules.

5. Tighten the two screws at either end of the module front panel by pushing them in and turning them
clockwise. Then, tighten the screws further using the flat-head screwdriver.

For information on cabling, see “Installing Power Supplies in a NetIron MLX-16 Chassis” on page 3-25, “Attaching
a Management Station” on page 3-49, and “Connecting a NetIron MLX Series Router” on page 4-5.

Installation Location

Before installing the router, plan its location and orientation relative to other devices and equipment. For cooling
purposes, allow a minimum of six inches of space between the sides, front, and the back of the chassis and walls
or other obstructions. If a chassis is installed within a perforated enclosure, the perforations must have openings of
at least 60 percent of the surface.

If you will be using a mechanical lift to move and install the chassis, make sure you allow enough working room.

Unpacking a NetIron MLX-16 Router

The NetIron MLX-16 router ships with several items. Review the list below, and verify the contents. If any items are
missing, contact the place of purchase.

• NetIron MLX-16 chassis with the appropriate number of switch fabric modules already installed in the slot
marked SF and a slot blank installed in all other module slots.

• Rack mount kit, including two L-shaped brackets and mounting screws.

NOTE: You must provide standard #12-24 pan-head screws for mounting the NetIron MLX Series chassis into a
rack.

• CD-ROM containing software images and the user documentation (including this guide).

• Warranty card.

• A 115V AC power cable for each AC power supply you purchase from Foundry.

To unpack a NetIron MLX-16 chassis, follow these steps:

1. Move the pallet to a staging area as close to the installation site as possible.

2. Position the shipping carton with the arrows pointing up.

5. Save the shipping carton, pallet, and packing materials in case you need to move or ship the chassis at a later
time.

Chassis Lifting Guidelines for NetIron MLX-16 Routers

WARNING: A fully-populated NetIron MLX-16 chassis is heavy. TWO OR MORE PEOPLE ARE REQUIRED

WHEN LIFTING, HANDLING, OR MOUNTING THESE DEVICES.

Follow these guidelines for lifting and moving a NetIron MLX-16 chassis:

• Before lifting or moving the chassis, disconnect all external cables.

• Do not attempt to lift a fully configured chassis by yourself. Using a mechanical lift to maneuver the chassis
into a rack is recommended. If a lift cannot be used, a minimum of four people must lift the chassis, and you
must remove components from the chassis before lifting.

Installing a Chassis in a Rack

Preparing to Mount a NetIron MLX-16 Chassis in a Rack

Keep the following in mind when mounting a NetIron MLX-16 chassis in a rack:

WARNING: A fully-populated NetIron MLX-16 chassis is heavy. TWO OR MORE PEOPLE ARE REQUIRED
WHEN LIFTING, HANDLING, OR MOUNTING THESE DEVICES. Do not use the handles on the power supply
units to lift or carry Chassis devices.

WARNING: Make sure the rack or cabinet housing the device is adequately secured to prevent it from becoming
unstable or falling over.

WARNING: Mount the devices you install in a rack or cabinet as low as possible. Place the heaviest device at the
bottom and progressively place lighter devices above.

Because of the weight of a fully loaded NetIron MLX-16 chassis, Foundry recommends mounting a chassis in a
rack before installing the modules and AC power supplies.

In a standard 19-inch (EIA310-D) rack, you can install up to three NetIron MLX-16 chassis.

For each NetIron MLX-16 chassis that you install in a rack, you must provide four standard #12-24 pan-head
screws with which to mount and secure the chassis. Before performing this task, you should have an assembled
rack and a #2 Phillips-head screwdriver.

This section describes the following tasks:

• “Attaching Mounting Brackets to a NetIron MLX-16 Chassis”

• “Mounting a NetIron MLX-16 Chassis in a Rack”

• “Removing the Slot Blanks”

Attaching Mounting Brackets to a NetIron MLX-16 Chassis

The NetIron MLX-16 chassis ships with a rack mount kit. The kit includes two L-shaped mounting brackets and
mounting screws.

The chassis sides have two sets of screw holes: one set for attaching the mounting brackets close to the chassis
front and another set for attaching the brackets toward the chassis center.

Attach the mounting brackets to the sides of the chassis as illustrated in Figure 3.17.

NOTE: The diagram shows locations for attaching the mounting brackets for either front-mount or mid-mount of
the NetIron MLX-16 chassis.

December 2008 © 2008 Foundry Networks, Inc. 3-21

Foundry NetIron MLX Series Installation and Basic Configuration Guide

Mounting a NetIron MLX-16 Chassis in a Rack

To mount a NetIron MLX-16 chassis in a rack, do the following:

1. Determine the position of each chassis in the rack, for example, a chassis with the fewest modules on top, a
chassis with more modules than the top chassis in the middle, and a fully populated chassis on the bottom.

2. Position the four screws for each chassis according to the spacings of the keyhole slots on the mounting
brackets as shown in Figure 3.18. Do not secure the screws completely; leave approximately 1/4 inch of
clearance between the back of the screw head and the rack.

Figure 3.17 Positioning the Screws in a Rack

3. Starting with the chassis that you want to mount in the lowest position in the rack, mount the chassis in the
rack as shown in Figure 3.18. With two or more people lifting the chassis, slip the wide portion of each
keyhole slot over the corresponding screw in the rack.

Figure 3.18 Mounting the NetIron MLX-16 or NetIron MLX-32 Chassis in a Rack

3-22 © 2008 Foundry Networks, Inc. December 2008

Installing a NetIron MLX Series Router

4. Slide the chassis down so that the screw heads are in the narrow portion of the keyhole slots.

5. Tighten the screws to secure the chassis in place.

NOTE: To provide better grounding of the chassis to the rack, attach the chassis to the rack using star washers.
Additionally, if any single hole grounding lugs are used star washers shall be used as a means to prevent rotation
of the lug.

6. Repeat Step 3 through Step 5 to mount each subsequent chassis in the same rack.

Removing the Slot Blanks

The NetIron MLX-16 chassis ships with slot blanks installed in all module slots. The slot blank covers a slot that
does not currently have a module installed in it, ensuring proper airflow within the chassis. If you plan to install a
module in a particular slot, you must remove the slot blank.

CAUTION: If you do not install a module in a slot, you must keep the slot blank in place. If you run the chassis
with an uncovered slot, the system may overheat. Tighten the screws that secure the slot blanks so that they
remain in place when removing adjacent panels or modules.

Although the slot blanks are different in size, the procedure for removing them from the NetIron MLX Series
chassis is the same. Therefore, this section provides one procedure that applies to all slot blanks.

You will need a flat-head screwdriver to perform this task.

To remove a slot blank, do the following:

1. Loosen the screws on either end of the slot blank by hand or with a flat-head screwdriver.

2. Pull the slot blank out of the chassis, and store it in a safe place for future use.

Installing NetIron MLX-16 Modules

This section provides one procedure that applies to all modules. The sequence for installing more than one
module is important to ensure proper fit. For the NetIron MLX-16 chassis, starting with the lowest row, and moving
upwards, install the modules left-to-right starting with the bottom row.

WARNING: The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building
or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be
metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4)
and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection
in order to connect these interfaces metallically to OSP wiring.

NOTE: The NetIron MLX Series modules are dedicated, which means that you must install them in the NetIron
MLX Series chassis only. For example, if you attempt to install the NetIron MLX Series management module in
another Foundry chassis or a management module intended for another Foundry chassis in the NetIron MLX
Series chassis, the chassis and module will not function properly.

Table 3.4 provides the chassis slot number(s) into which you must install the modules. Markings for the chassis
slots appear at the base of the slots.

If you are installing a redundant management module, see the chapter titled “Using a Redundant Management
Module” in the "Foundry NetIron XMR/MLX Configuration Guide" for information about how the redundant module
works, optional software configurations that you can perform, and how to manage the redundancy feature.

Before installing a module in the NetIron MLX-16 chassis, have the following on hand:

• An ESD wrist strap with a plug for connection to the ESD connector on the NetIron MLX Series chassis.

WARNING: For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.

• A large flat-head screwdriver.

To install a module in the NetIron MLX-16 chassis, do the following:

1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector on the chassis
front.

2. Remove the module from its packaging.

Chassis Slot Number

3. With the ejectors in the outward position, insert the module into the appropriate chassis slot and slide the card
along the card guide until the ejectors on either side of the module move close to the module front panel. See
special instructions, “Populating a NetIron MLX-16 Chassis” on page 3-25.

NOTE: When inserting the module into the chassis, make sure that the faceplate doesn’t overlap with the
faceplate of an adjacent Interface module.

4. Push the ejectors in until they are flush with the module front panel. This action will fully seat the module in
the backplane. Modules have a snug fit for maximum EMI protection.

5. Save the crate (including the shipping panel) in case the chassis needs to be shipped again.

Installing a NetIron MLX-32 Chassis in a Rack

This section describes the following tasks:

• Preparing to Mount a NetIron MLX-32 Chassis in a Rack

• Attaching mounting brackets to a chassis

• Mounting a NetIron MLX-32 chassis in a rack

Preparing to Mount a NetIron MLX-32 Chassis in a Rack

Keep the following in mind when mounting a NetIron MLX-32 chassis in a rack:

WARNING: Make sure the rack or cabinet housing the device is adequately secured to prevent it from becoming
unstable or falling over.

WARNING: Mount the devices you install in a rack or cabinet as low as possible. Place the heaviest device at the
bottom and progressively place lighter devices above.

Because of the weight of a fully loaded NetIron MLX-32 chassis, Foundry recommends mounting the chassis in a
rack before installing the modules and AC power supplies.

In a standard 19-inch (EIA310-D) rack, you can install one NetIron MLX-32 chassis.

For each NetIron MLX-32 chassis that you install in a rack, you must provide eight standard #12-24 pan-head
screws with which to mount and secure the chassis. Before performing this task, you should have an assembled
rack and a #2 Phillips-head screwdriver.

Attaching Mounting Brackets to a NetIron MLX-16 or NetIron MLX-32 Chassis

The NetIron MLX-16 and NetIron MLX-32 chassis ship with a rack mount kit that contains two L-shaped mounting
brackets and mounting screws.

The chassis sides have two sets of screw holes: one set for attaching the mounting brackets close to the chassis
front, and another set for attaching the brackets toward the chassis center.

Attach the mounting brackets to the sides of the chassis as illustrated in “ Mounting the NetIron MLX-16 or
NetIron MLX-32 Chassis in a Rack” on page 3-22.

NOTE: The diagram shows locations for attaching the mounting brackets for either front-mount or mid-mount of
the NetIron MLX-16 chassis. Mounting brackets for the NetIron MLX-32 chassis are attached in the same manner.

Mounting a NetIron MLX-32 Chassis in a Rack

Due to its larger size, the NetIron MLX-32 chassis has some requirements different from the other NetIron MLX
Series chassis. Use the following procedural changes when installing a NetIron MLX-32 chassis:

• Only one NetIron MLX-32 chassis can be mounted in a rack, positioned a low as possible.

• The empty NetIron MLX-32 chassis weighs approximately 325 lbs. You must use a mechanical device (such
as a material lift or work positioner), and four people are required to guide the chassis into place.

• When positioning the chassis into the rack from the mechanical lift, use the hand pockets in the sides and
back, and the lifting bar on the front of the chassis, and keep your back straight as you lift.

To install a NetIron MLX-32 chassis, use the following procedure:

4. Using a mechanical lift equipped with a lift plate, position the lift plate as close to the front of the chassis as
possible. Adjust the lift plate height to be even with the bottom of the chassis.

5. Slide the chassis onto the lift plate.

WARNING: Four or more people are required to position the unpopulated chassis into the rack.

WARNING: Do not use the handles on the power supply units or fan modules to position the chassis.

6. Secure the chassis to the mechanical lift with a strap to prevent tipping.

7. Carefully move the chassis and position it in front of the rack where it is to be installed.

8. Remove the strap securing the chassis to the lift.

9. With two people in front and two people in back, slide the chassis into the rack.

10. If you are installing the chassis 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 chassis in an
open-frame rack, install eight standard #12-24 pan-head screws into each of the open mounting holes aligned
with the rack, starting from the bottom.

Installing a NetIron MLX Series Router

11. Visually inspect the alignment of the chassis. If the chassis 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
chassis should be level.

Installing NetIron MLX-32 Modules

The NetIron MLX-32 ships with empty module slots, and upper and lower shipping panels installed.

WARNING: The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building
or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be
metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4)
and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection
in order to connect these interfaces metallically to OSP wiring.

CAUTION: If you do not install a module in a slot, you must leave the slot blank installed in the slot. If you run the
NetIron MLX-32 chassis with an uncovered slot, the system may overheat.

NOTE: The NetIron MLX Series modules are dedicated, which means that you must install them in the NetIron
MLX Series chassis only. For example, if you attempt to install the NetIron MLX Series management module in
another Foundry chassis or a management module intended for another Foundry chassis in the NetIron MLX
Series chassis, the chassis and module will not function properly.

If you are installing a redundant management module, see the chapter titled “Using a Redundant Management
Module” in the "Foundry NetIron XMR/MLX Configuration Guide" for information about how the redundant module
works, optional software configurations that you can perform, and how to manage the redundancy feature.

Before installing a module in the NetIron MLX-32 chassis, have the following on hand:

• An ESD wrist strap with a plug for connection to the ESD connector on the NetIron MLX-32 chassis.

WARNING: For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.

• A large flat-head screwdriver.

To install a module in the NetIron MLX-32 chassis, do the following:

1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector on the chassis
front.

2. Remove the module from its packaging.

3. Remove the two shipping panels by unscrewing the six captive screws holding each panel.

4. With the ejectors in the outward position, insert the module into the appropriate chassis slot and slide the card
along the card guide until the ejectors on either side of the module move close to the module front panel. See
special instructions, “NetIron MLX-32 Cable Management” on page 3-36.

NOTE: When inserting the module into the chassis, make sure that the faceplate doesn’t overlap with the
faceplate of an adjacent Interface module.

5. Push the ejectors in until they are flush with the module front panel. This action will fully seat the module in
the backplane. Modules have a snug fit for maximum EMI protection.

NetIron MLX-32 Module Installation Details

The sequence for installing more than one card is important to ensure proper fit in the NetIron MLX-32 chassis.
When populating the NetIron MLX-32, start with the middle slot, and work towards the edge. Always fill the bottom
slots of the upper and lower card cage of the NetIron MLX-32 first. See “ NetIron MLX-32 Chassis” on page 2-5
for slot locations.

NOTE: Do not insert interface modules running releases below 02.3.00 into slots 17 to 32 of a NetIron MLX-32
chassis. They should only be inserted into slots 1 to 16.

NOTE: Any empty slots must contain slot blanks to ensure proper air flow within the chassis.

NOTE: During the initially installation of the modules into a NetIron MLX 3200, Foundry recommends inserting

all the modules into the appropriate chassis slots before tightening the screws into the chassis.

Figure 3.27 Chassis Overview

Using the Insertion/Extraction Tool

Due to the high density of cables that the NetIron MLX-32 chassis can support, it may be difficult to insert and
remove the RJ-45 and optical connectors. An insertion/extraction tool has been provided in the NetIron MLX-32
accessory kit to make this task easier. See Figure 3.28.

December 2008 © 2008 Foundry Networks, Inc. 3-35

Foundry NetIron MLX Series Installation and Basic Configuration Guide

Hooked tab

Stepped tab

Figure 3.28 Insertion/Extraction Tool

Use the tool to grasp the boot or the plug of the modular connector at its narrow end (the end closest to the
attached cable), and insert the connector into the proper interface module. Grasping the boot or plug at the wide
end during insertion may cause the tool to be difficult to release and remove.

When using the tool to extract the boot or plug of a modular connector, cover the entire length of the boot or plug
with the tool. Notice that one end of the tool has a "hook" side. Use this side to compress the locking tab while you
remove the connector.

NetIron MLX-32 Cable Management

NetIron MLX-32 cable management is designed to ensure access to the power supplies at the bottom of the
chassis, and to keep the air inlet clear in the center of the chassis (this is essential for proper cooling). Cable
management hardware at the top, bottom and sides of the chassis will assist you in channeling the cables in the
proper direction.

In general, cables from the outer interface modules are routed horizontally and away from the chassis. With the
cable management upper cover swung open, cables from the remaining modules in the upper half of the chassis
are routed up, then outwards along the channels.

With the cable management lower cover swung open, the remaining modules in the lower half of the chassis follow
a similar path downwards, above the power supplies. Figure 3.29 diagrams the cable routing, with the upper and
lower covers removed for clarity.

Final Steps

Here are the final steps that you should complete in the order in which they are listed:

• “Attaching a Management Station”

• “Powering-On the Power Source”

• “Verifying Proper Operation”

Attaching a Management Station

You can manage the NetIron MLX Series system in the following ways:

• You can connect a PC or terminal to the management module’s serial (Console) port for a direct connection.
From this interface, you can configure the 10BaseT/100BaseTX/1000BaseTX Ethernet (management) port
with an IP address and either Telnet or SSH. This enables you to manage the device through the
10BaseT/100BaseTX/1000BaseTX Ethernet (management) port using either Telnet or SSH.

• You can connect the NetIron MLX Series router to your existing management network and manage the router,
along with other network devices, from a management station. To do this, you can connect a router to the
management module’s 10BaseT/100BaseTX/1000BaseTX Ethernet (management) port.

NOTE: The existing management network into which you can connect the 10/100 Ethernet port must be
separate and isolated from the network over which user packets are switched and routed. For information about
the management port’s functionality, see “Understanding How the Management Port Functions” on page 4-5.

For information about connecting a PC or terminal to the management module’s Console port or management
port, see “Attaching a PC or Terminal to the Console Port or Ethernet Port” on page 3-50. For information about
connecting a management port to a network, see “Attaching the Management Module’s Ethernet Port to a
Network” on page 3-50.

December 2008 © 2008 Foundry Networks, Inc. 3-49

Foundry NetIron MLX Series Installation and Basic Configuration Guide

Attaching a PC or Terminal to the Console Port or Ethernet Port

The management module’s Console port (which has a male DB-9 serial connector), and 10BaseT/100Base TX
Ethernet port (which has an RJ-45 UTP connector) allow you to attach a PC or terminal. From the Console port,
you can access the NetIron MLX Series router’s CLI directly from the PC or terminal or via a Telnet connection to
the PC or terminal. From the Ethernet port, you can access the NetIron MLX Series router’s CLI or Web
management interface directly from the PC or terminal or via a Telnet connection to the PC or terminal.

Before performing this task, you need the following items:

• PC running a terminal emulation application or a terminal.

• If connecting the PC or terminal to the Console port, a straight-through EIA/TIA DB-9 serial cable with one
end terminated in a female DB-9 connector and the other end terminated in a male or female DB-9 or DB-25
connector, depending on the specifications of your PC or terminal. You can order the serial cable separately
from Foundry Networks or build your own cable. If you prefer to build your own, see the pinout information in
“Console Port Pin Assignments” on page 8-5.

• If connecting the PC or terminal to the Ethernet port, a Category 5 UTP crossover cable, which you must
supply. For information about the management port pin assignments, see “Management Port Pin
Assignments” on page 8-6.

To attach a PC or terminal to the Console port or Ethernet port, do the following:

1. Connect a PC or terminal to the Console port or Ethernet port using the appropriate cable.

2. Open the terminal emulation program, and set the session parameters as follows:

• Baud: 9600 bps

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: None

Attaching the Management Module’s Ethernet Port to a Network

The management module’s 10BaseT/100BaseTX/1000BaseTX Ethernet (management) port (RJ-45 UTP
connector) allows you to connect the management port to a network. A management station in your existing
management network can then access a NetIron MLX Series router using the IronView Network Manager.

To attach the management module’s Ethernet port to a network, you need a Category 5 UTP straight-through
cable (not supplied by Foundry). Connect one end of the straight-through cable to the management port and the
other end to the network.

Powering-On the Power Source

After you complete the hardware installation, you can power-on your power source:

1. Verify that all modules and power supplies are fully and properly installed and no module slots are uncovered.

CAUTION: If you do not install a module in a slot, you must keep the slot blank in place. If you run the chassis
with an uncovered slot, the system may overheat.

2. If you are supplying a DC power source to a NetIron MLX Series chassis, attach the power cables to the DC
power supply as described in the appropriate section:

• “Connecting DC Power to a NetIron MLX-4 Chassis” on page 3-10

• “Connecting DC Power to a NetIron MLX-8 Chassis” on page 3-18

• “Connecting DC Power to a NetIron MLX-16 Chassis” on page 3-27

• “Connecting DC Power to a NetIron MLX-32 Chassis” on page 3-47

3-50 © 2008 Foundry Networks, Inc. December 2008

Installing a NetIron MLX Series Router

Connect the other end of the cables to the DC power source. Repeat this step for each installed DC power
supply. Then switch on the power source.

3. If your power source is AC, attach one end of a Foundry-supplied AC power cord to the AC power supply as
described in the appropriate section:

• “Connecting AC Power to a NetIron MLX-4 Chassis” on page 3-9

• “Connecting AC Power to a NetIron MLX-8 Chassis” on page 3-17

• “Connecting AC Power to a NetIron MLX-16 Chassis” on page 3-26

• “Connecting AC Power to a NetIron MLX-32 Chassis” on page 3-46

Insert the other end into a 115V/120V wall outlet. Repeat this step for each installed AC power supply.

WARNING: If the installation requires a different power cord than the one supplied with the device, make
sure you use a power cord displaying the mark of the safety agency that defines the regulations for power
cords in your country. The mark is your assurance that the power cord can be used safely with the device.

NOTE: The NetIron MLX Series router is designed to provide uninterrupted service even when you insert or
remove the management modules and the interface modules. Therefore, the system does not have a
separate on/off power switch. To turn the system off, simply unplug the power cord(s).

NOTE: The wall outlet should be installed near the equipment and should be easily accessible.

4. Verify that the NetIron MLX Series router has initialized successfully. For information, see “Verifying Proper
Operation”below.

Verifying Proper Operation

To verify the proper operation of the NetIron MLX Series chassis after power on, you can do the following:

• Observe the LEDs

• Display the status of the modules using the CLI

Observing the LEDs

After a NetIron MLX Series chassis powers on, you can observe its LEDs to verify that it initialized successfully.

The Status column shows the module status. A management module can have one of the following statuses:

• ACTIVE – The module is currently the active management module.

• STANDBY – The module is currently the standby management module.

• COMING UP – The module is coming up as the standby module. This status occurs if the standby
management module becomes the active module, which is called a switchover.

The switch fabric module can have one of the following statuses:

• ACTIVE – The module is up and running.

• BAD – The management module cannot initialize the switch fabric module.

An interface module can have one of the following statuses:

• CARD_STATE_INIT – The system detects the module but the module is not up and running yet.

• CARD_STATE_BOOT – The module is booting.

• CARD_STATE_INTERACTIVE – The module is booting from interactive mode.

• CARD_STATE_LP_SYNC – The module’s IronWare images are synchronized between the management
module and interface module.

• CARD_STATE_SYNC – The system is currently synchronizing the module’s IronWare images between the
management module and interface module.

• CARD_STATE_SOFTWARE_LOADED – The module has loaded its IronWare image.

• CARD_STATE_POWER_OFF – The module does not have power.

• CARD_STATE_UP – The module is up and operating normally.

• CARD_STATE_FAILED – The management module was unable to bring up an interface module properly. If
you observe this status, make certain that the interface module is installed properly. For more information,
see “Installing NetIron MLX-4 Modules” on page 3-7, “Installing NetIron MLX-8 Modules” on page 3-15,

Connecting a NetIron MLX Series Router

to a Network Device

This chapter provides information about performing the following tasks:

• Securing access to the NetIron MLX Series router’s CLI by assigning passwords

• Configuring IP addresses for the management, Ethernet, virtual, and loopback interfaces

• Understanding how the management port functions

• Connecting a NetIron MLX Series router to another networking device

Chapter 4

• Testing network connectivity

This chapter also includes information about troubleshooting a network connection in case a problem arises

WARNING: The procedures in this manual are for qualified service personnel.

Assigning Permanent Passwords

By default, the NetIron MLX Series router’s CLI is not protected by passwords. To secure CLI access, Foundry
strongly recommends assigning passwords. (For additional information on security, see the Foundry Security
Guide.)

The CLI contains the following access levels:

• Privileged EXEC – This level is also called the Enable level and can be secured by a password. You can
perform tasks such as manage files on the management module’s flash memory or a PCMCIA flash card in
the management module’s slots 1 or 2, save the system configuration to flash memory, and clear caches at
this level.

• CONFIG – The configuration level. This level lets you configure the system’s IP address and configure routing
features. To access the CONFIG mode, you must already be logged into the Privileged level of the EXEC
mode.

NOTE: You cannot assign a password using the Web management interface. You can assign passwords using
the IronView Network Manager if an Enable password for a Super User is already configured on the device.

December 2008 © 2008 Foundry Networks, Inc. 4-1

Foundry NetIron MLX Series Installation and Basic Configuration Guide

You can set the following levels of Enable passwords:

• Super User – Allows complete read-and-write access to the system. This is generally for system
administrators and is the only password level that allows you to configure passwords.

NOTE: You must set a super user password before you can set other types of passwords.

• Port Configuration – Allows read-and-write access for specific ports but not for global (system-wide)
parameters.

• Read Only – Allows access to the Privileged EXEC mode and CONFIG mode but only with read access.

To set passwords:

1. At the opening CLI prompt, enter the following command to change to the Privileged level of the EXEC mode:

NetIron> enable
NetIron#

2. Access the CONFIG level of the CLI by entering the following command:

NetIron# configure terminal
NetIron(config)#

3. Enter the following command to set the super-user password:

NetIron(config)# enable super-user-password <text>

NOTE: You must set the super-user password before you can set other types of passwords.

4. Enter the following commands to set the port configuration and read-only passwords:

NetIron(config)# enable port-config-password <text>
NetIron(config)# enable read-only-password <text>

NOTE: If you forget your super-user password, see the Release Notes.

Syntax: enable super-user-password | read-only-password | port-config-password <text>

Passwords can be up to 48 characters long.

Configuring IP Addresses

The NetIron MLX Series routers implement separate data and control planes. This architecture affects how you
assign IP addresses. Table 4.1 outlines the interfaces to which you can assign IP addresses.

In this table, “in band” refers to an interface over which user packets are routed, while “out of band” refers to an
interface over which control packets related to system management are forwarded.
