Management modules

Tab le 1 lists the management modules that are available for PowerConnect B-MLXe routers.

TABLE 1 Management modules

Part number Description

NI-MLX-MR PowerConnect B-MLXe management module, 1 GB SDRAM, dual PCMCIA slots, EIA or

The management module controls the hardware components, runs the networking protocols, and provides the Real Time Operating System (RTOS).

TIA-232 and 10/100/1000 Ethernet ports for out-of-band management.

Each router requires one management module, and can accommodate a second module for redundancy. A redundant management module works in conjunction with the active management module. If the active module becomes unavailable, the redundant management module automatically takes over the system operation, minimizing system downtime. For information about the redundancy feature, refer to the “Using a Redundant Management Module” chapter in the PowerConnect B-MLXe Configuration Guide.

Management modules are installed in dedicated slots marked M1 and M2. By default, the module installed in slot M1 is the active management module.

Management modules are hot-swappable, which means you can remove and replace them without powering down the system. Figure 4 shows the management module front panel.

FIGURE 4 Management module front panel

The front panel contains the following control features:

• Two PCMCIA slots

• A console port

• A 10/100/1000 Ethernet port

• Six LEDs

Router modules

NOTE

PCMCIA slots

PCMCIA slots support flash PC cards. A flash PC card provides storage space in addition to system flash memory. You can store boot images, startup configuration files, running configuration files, and other system files on the flash PC card. This allows you to perform system management tasks, such as copying files between flash PC cards, or copying files between a flash PC card and flash memory.

Console port

The console port is a standard DB-9 serial connector through which you can attach a PC or terminal to configure the router using the CLI.

The console port interfaces the control plane only. It does not interface the data plane.

10/100/1000 Ethernet port

The management module also contains a 10BaseT, 100BaseTX, or 1000BaseTX auto-sensing, auto-negotiating Ethernet port. This port has an RJ45 unshielded twisted pair (UTP) connector.

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

• Connecting a PC to configure, monitor, and manage the system through a Telnet or SSHv2

connection.

• Connecting to the 10BaseT, 100BaseTX, or 1000BaseTX port for connectivity to your existing

management network. You can then access the router and configure, monitor, and manage the system from a management station.

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 functionality of the management port, refer to “Understanding

management port functions” on page 95.

For information about connecting a PC to the 10/100/1000 Ethernet port, refer to “Attaching a

management station” on page 205.

Unlike the 10 Gbps Ethernet ports, the out-of-band port does not interface the LAN. Instead, the out-of-band port can interface with a separate system management network, and allows you to do the following tasks:

• Access the router through Telnet, the Web management interface, or the SNMP Network

Manager software.

• Access a TFTP server to perform system upgrade tasks.

• Access SNMP messages or protocol data units (PDUs).

• Send Syslog packets.

• Access the system through RADIUS AAA.

Part number Description

NI-X-4-HSF High speed switch fabric module for 4-slot routers

NI-X-16-8-HSF High speed switch fabric module for 8- and 16-slot routers

Switch fabric modules switch packets from one interface module to another. PowerConnect B-MLXe routers can be configured with multiple switch fabric modules as described here:

• 4-slot router: Accommodates three switch fabric modules (two required and one redundant) for

a fully-loaded system. Ships with two switch fabric modules. You must purchase an additional switch fabric module to equip your router for redundancy.

• 8-slot router: Accommodates three switch fabric modules (two required and one redundant) for

a fully-loaded system. Ships with two switch fabric modules. You must purchase an additional switch fabric module to equip your router for redundancy.

• 16-slot router: Accommodates four switch fabric modules (three required and one redundant)

for a fully-loaded system. Ships with three switch fabric modules. You must purchase an additional switch fabric module to equip your router for redundancy.

PowerConnect B-MLXe router switch fabric modules are dedicated, which means that they function properly in PowerConnect B-MLXe routers only. If you attempt to install a PowerConnect B-MLXe router switch fabric module in another Dell device or a switch fabric module intended for another Dell device in a PowerConnect B-MLXe router, the router and switch fabric module will not function properly.

Figure 10 shows the front panel of a switch fabric module.

NOTE

DANGER

High-speed switch fabric modules

Generation 2 (G2) high-speed fabric (HSF) modules support wire-speed forwarding for all packet sizes, including jumbo frames.

HSF modules are supported on PowerConnect B-MLXe routers and are interoperable with all existing interface modules.

HSF modules are hot-swappable, which allows you to install or replace them while the system is powered up and running.

Power supplies

PowerConnect B-MLXe routers support the following power supply options:

• 4-slot router: Ships with one power supply, but can accommodate three AC power supplies (one

required and two redundant). To equip your router for redundancy, you must purchase one or two additional power supplies.

• 8-slot router: Accommodates four AC power supplies (two required and two redundant).

Because power is supplied over a common power bus, any power supply installed in addition to the two required will provide backup for any supply that fails. For full redundancy for both of the required power supplies, you must add two additional power supplies.

• 16-slot router: Accommodates eight AC power supplies (four required and four redundant).

Because power is supplied over a common power bus, any power supply installed in addition to the four required will provide backup for any power supply that fails. For full redundancy for all of the required power supplies, you must add four additional power supplies.

For power supply specifications, refer to “Power specifications” on page 175.

Power supplies provide power to all router components, share the workload equally, and report status to the management module. If the management module detects that a power supply has failed or overheated, the management module redistributes the workload of the failed power supply to the remaining power supplies.

Power supplies have three LEDs on the faceplate. These LEDs provide status for input power, output power, and notification of alarms that have been sent. If the input power and output power LEDs are on (a steady green), the power supply is providing power to the router components. For more information about the power supply LEDs, refer to the AC power supply sections in Table 27 on page 207.

After a power supply is removed from a router, the software determines if there is enough power to operate all of the interface modules. If it determines that there is not enough power, some interface modules will be powered off.

Power supplies are hot-swappable, which means they can be removed and replaced while the router is powered on and running. However, Dell recommends that you disconnect a power supply from its power source before removing and replacing the supply. The 4-, 8-, and 16-slot

PowerConnect B-MLXe Hardware Installation Guide 17 53-1002111-01

Router modules

router 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 router could be damaged.

Rack mounting brackets

All routers ship with pre-installed mounting brackets that allow you to front-mount the router in a standard 19-inch (EIA310-D) rack. For instructions about how to mount the router in a rack, refer to the installation chapter that is appropriate for your router model.

You can also mid-mount your 4-, 8- or 16-slot router using two L-shaped mounting brackets that come in a mid-mount kit (ordered separately). The mid-mount kit comes with instructions for installing the mounting brackets and mounting the router in a rack. Contact Dell for more information about the mid-mount bracket kit.

Cooling system for PowerConnect B-MLXe routers

The cooling systems for PowerConnect B-MLXe routers contain the following components:

• 4-slot router: Equipped with a fan assembly that contains two 4-speed fans and two fan

controllers to support redundancy.

• 8-slot router: Equipped with a fan assembly containing four 4-speed fans and four fan

controllers to support redundancy.

• 16-slot router: Equipped with two high-speed fan assemblies. Each fan assembly contains two

4-speed fans with 16 fan controllers to support redundancy.

Figure 11 and Figure 12 show the fan locations for 4-slot and 8-slot routers. Figure 13 and Figure 14 show the fan locations for 16-slot routers.

FIGURE 14 Rear fan location for PowerConnect B-MLXe-16 routers

1 Rear fan assemblies

At startup, the fans operate at high speed. After a period of time, the management module changes the fan speed to low.

By default, the router polls the temperature sensor on each module every 60 seconds for a temperature reading. Depending on the results, the router will:

• 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 down the module if the temperature exceeds the highest threshold.

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

“Changing temperature thresholds for modules and fan speeds” on page 107.

The fan control modules include a bi-color LED, which indicates the status of the fans. The router ships with fan assemblies fully installed. Fan assemblies are hot-swappable, which means you can remove and replace them without powering down the system.

NIBI-16-FAN-EXH-A high-speed fan assemblies

NIBI-16-FAN-EXH-A high-speed fan assemblies are required for PowerConnect B-MLXe routers when you install NI-MLX-10Gx8-M, NI-MLX-10Gx8-D, or NI-MLX-1Gx48-T-A modules. PowerConnect B-MLXe-16 routers ship with high-speed fan assemblies factory installed. Refer to “Installing

NIBI-16-FAN-EXH-A fan assemblies” on page 167 for high-speed fan installation instructions.

Installation precautions

CAUTION

DANGER

Power precautions

Use a separate branch circuit for each AC power cord for redundancy in case one of the circuits fails.

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

Disconnect the power cord from all power sources to completely remove power from the router.

Make sure that the power source circuits are properly grounded, then use the power cord supplied with the router to connect it to the power source.

If the installation requires a different power cord than the one supplied with the router, 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 router.

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

Mount the routers you install in a rack or cabinet as low as possible. Place the heaviest router at the bottom and progressively place lighter routers above.

Page 37

Installing a PowerConnect B-MLXe-4 router

CAUTION

Ensure that the router 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 router. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the routers near the input power connectors.

PowerConnect B-MLXe routers with AC power sources 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.

For the DC input circuit to the system of PowerConnect B-MLXe-4. PowerConnect B-MLXe-8, and PowerConnect B-MLXe-16 routers (1800W supply), make sure there is a UL-Listed 60 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to the power supply. The input wiring for connection to the product should be copper wire, 6 AWG, marked VW-1, and rated minimum 90C.

For the DC input circuit to the system of PowerConnect B-MLXe-4. PowerConnect B-MLXe-8, and PowerConnect B-MLXe-16 routers (1200W supply), make sure there is a UL-Listed 30 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to the power supply. The input wiring for connection to the product should be copper wire, 6 AWG, marked VW-1, and rated minimum 90C.

For the NEBS-compliant installation of PowerConnect B-MLXe-4, PowerConnect B-MLXe--8, and PowerConnect B-MLXe-16 routers with AC systems, use a ground wire of at least 6 American Wire Gauge (AWG). The ground wire should have an agency-approved crimped connector (provided with the device) attached to one end, with the other end attached to building ground. The connector must be crimped with the proper tool, allowing it to be connected to both ground screws on the enclosure. Before crimping the ground wire into the provided ground lug, ensure the bare copper wire has been cleaned and antioxidant is applied to the bare wire.

NOTE

Illustrations in this chapter may differ slightly from the actual equipment.

Preparing the installation site

Before installing the router, plan the 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 router and walls or other obstructions. If a router is installed in a perforated enclosure, the perforations must cover at least 60 percent of the surface.

This equipment is suitable for installation in a Network Telecommunication facility and where NEC requirements apply. Additionally, it may be installed in either a Common Bonding Network (CBN) or Isolated Bonding Network (IBN). It is not intended for Outside Plant (OSP) installations.

Ensure that the proper cabling is installed at the site.

For information on cabling, refer to “Installing power supplies in a PowerConnect B-MLXe-4 router” on page 38, “Attaching a management station” on page 68, and “Connecting the router to a

network device” on page 95.

Unpacking a PowerConnect B-MLXe-4 router

The PowerConnect B-MLXe-4 router ships with the following items:

• Router chassis with switch fabric modules installed in slots marked SF, slot blanks installed in

all empty module slots, and mounting brackets attached for front-mount.

• Insertion or extraction tool for use with RJ45 and fiber-optic connectors.

If any items are missing, contact the place of purchase.

Unpacking steps

Follow these steps to unpack your PowerConnect B-MLXe-4 router.

1. Remove the router from the shipping carton.

2. Save the shipping carton and packing materials in case you need to move or ship the router at a later time.

Installing a PowerConnect B-MLXe-4 router in a rack or cabinet

Your PowerConnect B-MLXe-4 router ships from the factory with mounting brackets attached. You can mount your router in the following ways:

• Front-mount in a standard two-post rack using the factory-installed brackets.

• Mid-mount in a standard two-post rack by moving the factory-installed brackets to the center of

the device

• Mount the device in a four-post rack or cabinet using the Cabinet Mount Kit. Refer to

“Mounting in a 4-post rack or cabinet” on page 29.

53-1002111-01

Page 39

Installing a PowerConnect B-MLXe-4 router

NOTE

Because of the weight of a fully loaded PowerConnect B-MLXe-4 router, Dell recommends mounting it in a rack before installing the modules and AC power supplies.

You can install up to eight PowerConnect B-MLXe-4 routers in a standard 19-inch (EIA310-D) two-post rack using the factory-installed mounting brackets for either front- or mid-mounts.

If you use the air duct rack mount method, you can install up to six PowerConnect B-MLXe-4 routers in a cabinet or four-post rack using the cabinet mounting kit.

Mounting your device in a standard rack

The factory-installed mounting brackets allow you to front-mount or mid-mount your device in the rack. For a mid-mount, you must remove the factory installed brackets from the front edge of the device and install them using the holes in the center-sides of the device. Refer to Figure 16.

You will need to provide four standard #12-24 pan-head screws (per router) to secure routers in the rack. You will also need a #2 Phillips screwdriver. Complete the following steps.

When connecting the device to the rack frame, use thread-forming screws and paint-piercing washers.

1. Determine the position of each router in the rack according to the weight of the router. For example, mount the router with the fewest modules near the top of the rack, a router with more modules near the middle of the rack, and fully populated routers near the bottom of the rack.

2. Using the keyhole slots in the router mounting brackets as a guide, align one screw per rack post, as shown in Figure 33. On one side of the rack, the screw should align with the top hole in the mounting bracket. On the other side of the rack, the screw should align with the bottom hole of the mounting bracket. When tightening these screws, leave approximately 1/4 inch of clearance between the back of the screw head and the rack post.

Installing PowerConnect B-MLXe-4 modules

The sequence for installing multiple modules is important to ensure proper fit. The recommended sequence for the PowerConnect B-MLXe-4 router is to install right-to-left, beginning with the lowest row and moving up.

Installation procedures are identical for interface, management and switch fabric modules.

The intra-building ports of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports 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.

PowerConnect B-MLXe modules are dedicated, which means that you must install them in PowerConnect B-MLXe routers only. If you install a PowerConnect B-MLXe module in a non-PowerConnect B-MLXe router, or install a module intended for a non-PowerConnect B-MLXe router in a PowerConnect B-MLXe router, the router and module will not function properly.

For information about how to disable and re-enable power to interface modules, see “Disabling and

re-enabling power to interface modules” on page 99

Tab le 13 identifies the router slot numbers where the modules must be installed. An identifying

Installing a PowerConnect B-MLXe-4 router

CAUTION

The PowerConnect B-MLXe-4 router ships with slot blanks installed in all empty module slots. The slot blanks help ensure proper airflow inside the router. You must remove the slot blank to install a module into a slot.

If you do not install a module in a slot, you must keep the slot blank in place. If you operate the router 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 differ in size, the procedure for removing them is identical. You will need a flat-blade screwdriver to remove slot blanks.

Slot blank removal steps

Follow these steps to remove a slot blank.

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

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

If you are hot-swapping a module, allow a minimum of two seconds after a module (or power supply or fan tray) has been removed before inserting a module in the same slot.

Module installation steps

Follow these steps to install a module.

1. If you are installing a module in a slot which may have been configured for a different module type, remove the old configuration information by following these steps.

a. Use the show running-config command in config mode to determine the current

configuration of the slot.

PowerConnect(config)# show running-config Current configuration: ! ver V5.1.0aT163 module 1 ni-mlx-24-port-1g-copper !

This example shows that slot 1 has already been configured for a 24-port 1 Gbps copper interface module.

b. Enter the no module <slot-number> <module-type> command to remove the configuration

from slot 1, using the information shown as a result of the show running-config command.

PowerConnect(config)# no module 1 ni-mlx-24-port-1g-copper

This example removes the existing configuration from slot 1, leaving it ready for a new module.

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

3. Remove the module from the packaging.

Installing a PowerConnect B-MLXe-8 router

NOTE

• Do not attempt to lift a fully configured router by yourself.

• It is recommended that you install router components after you have installed the router in a

rack.

Installing a PowerConnect B-MLXe-8 router in a rack

Because of the weight of a fully loaded PowerConnect B-MLXe-8 router, Dell recommends mounting it in a rack before installing the modules and AC power supplies.

You can install up to six PowerConnect B-MLXe-8 routers in a standard 19-inch (EIA310-D) rack using the standard rack installation method. If you use the cabinet mounting kit, you can install up to 4 PowerConnect B-MLXe-8 routers in a standard 19-inch rack.

Front- or mid-mount your device in a standard rack

Your PowerConnect B-MLXe-8 router ships from the factory with mounting brackets attached for front-mount installation in a standard rack. You can also use these brackets for a mid-mount installation by simply removing the brackets from the front edges of the device and re-attaching them in the center sides of the device using the pre-drilled holes. Refer to Figure 27.

You will need to provide four standard #12-24 pan-head screws (per router) and a #2 Phillips screwdriver to secure routers in the rack.

When connecting the device to the rack frame, use thread-forming screws and paint-piercing washers.

Follow these steps to mount your device in a standard rack in either a front- or mid-mount configuration.

1. Determine the position of each router in the rack according to weight. For example, mount the router with the fewest modules near the top of the rack, the router with more modules near the middle of the rack, and a fully populated router near the bottom of the rack.

2. Using the keyhole slots in the router mounting brackets as a guide, align one screw per rack post, as shown in Figure 26. On one side of the rack, the screw should align with the top hole in the mounting bracket. On the other side of the rack, the screw should align with the bottom hole of the mounting bracket. When tightening these screws, leave approximately 1/4 inch of clearance between the back of the screw head and the rack post.

Installing PowerConnect B-MLXe-8 modules

The sequence for installing multiple modules is important to ensure proper fit. The recommended sequence for the PowerConnect B-MLXe-8 router is to install right-to-left, beginning with the lowest row and moving up.

installation instructions are identical for interface, management, and switch fabric modules.

The intra-building ports of the equipment or subassembly are suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports 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.

PowerConnect B-MLXe modules are dedicated, which means that you must install them in the PowerConnect B-MLXe router only. If you try to install a PowerConnect B-MLXe module in a non-PowerConnect B-MLXe router, or install a module intended for a non-PowerConnect B-MLXe router in a PowerConnect B-MLXe router, the router and module will not function properly.

Tab le 14 identifies the router slot numbers where the modules must be installed. An identifying

label can be seen at the base of each slot.

For information about how to disable and re-enable power to interface modules, see “Disabling and

Installing a PowerConnect B-MLXe-16 router

CAUTION

Reset fan speed to auto

For PowerConnect B-MLXe 16-slot routers, if you insert a module into a slot where the fan speed for a previous module was manually configured, you will need to change the fan speed back to auto. For example, if the fan speed was manually configured to “slow”, and you are installing a module that requires more cooling power, the “slow” setting will cause the module to overheat. To configure the fan speed to auto, enter the following command:

NetIron# set-fan-speed auto

The PowerConnect B-MLXe-16 router ships with slot blanks installed in all empty module slots. The slot blanks help ensure proper airflow inside the router. You must remove the slot blank to install a module in a slot.

Although the slot blanks differ in size, the procedure for removing them is identical. You will need a flat-blade screwdriver to perform this task.

Slot blank removal steps

Follow these steps to remove a slot blank.

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

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

If you are hot-swapping a module, allow a minimum of two seconds after a module (or power supply or fan tray) has been removed before inserting a module in the same slot.

Module installation steps

Follow this procedure to install modules in the router.

1. If you are installing a module in a slot which may have been previously configured for a different module type, remove the old configuration information using this procedure:

a. Use the show running-config command in config mode to determine the current

configuration of the slot.

MLXe-16(config)# show running-config Current configuration: ! ver V5.1.0aT163 module 1 ni-mlx-24-port-1g-copper !

This example shows that slot 1 is currently configured for a 24-port 1 Gbps copper interface module.

64 PowerConnect B-MLXe Hardware Installation Guide

53-1002111-01

Page 77

Installing a PowerConnect B-MLXe-16 router

NOTE

b. With the module designation from show running-config command output, use the no

module <slot-number> <module-type> command to remove the configuration from slot 1.

MLXe-16(config)# no module 1 ni-mlx-24-port-1g-copper

This command removes the configuration from slot 1, leaving it ready for a new module.

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

3. Remove the module from the packaging.

4. Insert the module into the slot, and slide the module along the card guide until the ejectors on either side of the module rotate towards the module front panel.

When inserting a module in the router, make sure that the module faceplate does not overlap the faceplate of an adjacent module.

5. Rotate the ejectors flush with the module faceplate. This action will fully seat the module in the backplane.

6. Tighten the two screws on the module faceplate by pushing them in and turning them clockwise. Complete the tightening process using the flat-blade screwdriver.

7. En te r t h e write memory command to ensure that the slot will be correctly configured for the new module after a reboot.

MLXe-16(config)# write memory Write startup-config done.

Final steps

Complete these steps in the order listed:

• “Attaching a management station”

• “Activating the power source”

• “Verifying proper operation”

Attaching a management station

You can manage your router in the following ways:

• Connect a PC or terminal to the console port on the management module. From this port, you

can assign an IP address to the management module and establish connections through Telnet or SSH.

• Connect the router to your existing management network and manage the router and other

network devices from a management station.

The management network that you connect to through the 10/100 Ethernet port must be separate and isolated from the network over which user packets are switched and routed. For information about functionality on the management port, Refer to “Understanding

management port functions” on page 95.

Attaching a PC or terminal to the console port or Ethernet port

You can attach a PC or terminal to either the console port (which has a male DB-9 serial connector), or the 10/100/1000 or 1000Base TX Ethernet port (which has an RJ45 UTP connector) on the management module. From the console port, you can access the router CLI directly from the PC or terminal or through a Telnet connection. From the Ethernet port, you can access the router CLI or Web management interface directly from the PC or terminal or through a Telnet connection.

Before performing this task, have the following items available:

• PC running a terminal emulation application or a terminal.
