exceed 40οC (104οF).
Make sure the air flow around the front, sides, and back of the chassis is not restricted.
If you do not install a module in a slot, you must keep the slot blank in place. If you operate
the chassis with an uncovered slot, the system may overheat.
Never leave tools inside the chassis.
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 chassis.
Disconnect the power cord from all power sources to completely remove power from the
chassis.
Make sure that the power source circuits are properly grounded, then use the power cord
supplied with the chassis to connect it to the power source.

DANGER
DANGER
CAUTION
CAUTION
CAUTION
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 chassis.
Make sure the rack or cabinet housing the chassis is adequately secured to prevent it from
becoming unstable or falling over.
Mount the chassis in a rack or cabinet as low as possible. Place the heaviest chassis at the
bottom and progressively place lighter units above.
Ensure that the chassis 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 chassis. Compare this total
with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
chassis near the input power connectors.
B-MLXe series products 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.

Follow these steps to mount a PowerConnect B-MLXe Series chassis in a rack.
You must provide standard #12-24 pan-head screws to mount each chassis in a rack. You will need a Phillips
screwdriver to perform this task.
1. Determine the position of each chassis in the rack. For example, place units with the fewest modules near the
top of the rack, units with more modules near the middle of the rack, and fully populated units near the bottom
of the rack.
2. Using the keyhole slots in the chassis mounting brackets as a guide, align one screw per rack post, as shown in
Figure 5 on page 13. 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.

4. Slide the chassis down so that the mounting screw heads are in the narrow portion of the keyhole slots.
5. Tighten the screws to secure the chassis in place. For extra support, use additional screws.
Mounting the B-MLXe 8-slot chassis in a rack
For better grounding of the chassis to the rack, attach the chassis using star washers. You should also use star
washers with any single-hole grounding lugs to keep the lugs from rotating.
6. Repeat step 2 through step 5 to mount each chassis in the rack.
Installing modules
Use these procedures to install modules into empty slots. The same procedure applies to all modules.
The following sequence for installing multiple modules is important to ensure proper fit:
•
For the 4-slot and 8-slot chassis, install modules right-to-left, beginning with the lowest row and moving up.
•
For the 16-slot chassis, begin by filling the slots from the left side of the router, and work towards the right side.
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.

Before installing a module in the PowerConnect B-MLXe Series chassis, have the following on hand:
DANGER
NOTE
•
An ESD wrist strap with a plug for connection to the ESD connector on the PowerConnect B-MLXe Series chassis.
For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
•
A large flat-head screwdriver.
Follow the steps given below to install a module in the PowerConnect B-MLXe Series chassis:
1. If you are installing a module in an empty slot that was not previously configured for a different module, go on to
step 2. 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.
PowerConnect(config)# show running-config
Current configuration:
!
ver V5.0.0T163
module 1 ni-mlx-24-port-1g-copper
!
This example shows that slot 1 is currently configured for a 20-port 1 Gbps copper interface module.
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.
PowerConnect(config)# no module 1 ni-mlx-20-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 chassis, 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. E nt e r t he write memory command to ensure that the slot will be correctly configured for the new module after a
reboot.

Managing cables
NOTE
For information on managing cables attached to the PowerConnect B-MLXe Series, refer to your hardware
installation guide.
Attaching a management station
You can manage the PowerConnect B-MLXe 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 PowerConnect B-MLXe Series chassis to your existing management network and manage
the chassis, along with other network devices, from a management station. To do this, you can connect a
chassis to the management module’s 10BaseT/100BaseTX/1000BaseTX Ethernet (management) port.
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 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,” next. For information about connecting a
management port to a network, see “Attaching the management module’s Ethernet Port to a network” on page 25.
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 PowerConnect B-MLXe Series chassis 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 PowerConnect B-MLXe Series 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
Dell or build your own cable. If you prefer to build your own, see the pinout information in your hardware
installation guide.
•
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, refer to your hardware installation guide.
Follow the steps given below to attach a PC or terminal to the Console port or Ethernet port.
1. Connect a PC or terminal to the Console port or Ethernet port using the appropriate cable.

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 PowerConnect B-MLXe Series chassis using the management application.
To attach the management module’s Ethernet port to a network, you need a Category 5 UTP straight-through cable
(not supplied by Dell). Connect one end of the straight-through cable to the management port and the other end to
the network.
Activating 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.
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 your power source is AC, attach one end of a Dell-supplied AC power cord to the AC power supply as described
in “Connecting AC power” on page 21.
Insert the other end into a 115V or 120V wall outlet. Repeat this step for each installed AC power supply.
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.
The PowerConnect B-MLXe Series chassis 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 cords.
The wall outlet should be installed near the equipment and should be easily accessible.

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.
4. Verify that the PowerConnect B-MLXe Series chassis has initialized successfully. For information, see “Verifying
proper operation,” below.
Verifying proper operation
To verify the proper operation of the PowerConnect B-MLXe 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 PowerConnect B-MLXe Series chassis powers on, you can observe its LEDs to verify that it initialized
successfully. Refer to your hardware installation guide for a complete description of LED operation and status
messages displayed through the CLI show module command.
If a problem persists, contact technical support.
Displaying the module status
After you have attached a PC or terminal to the management module’s Console or Ethernet port and the
PowerConnect B-MLXe Series chassis has initialized successfully, press Enter to display the following CLI prompt in
the terminal emulation window:
PowerConnect>
If you do not see this prompt, do the following:
1. Make sure the cable is securely connected to your PC or terminal and the Console port or Ethernet port.
2. Check the settings in your terminal emulation program. In addition to the session settings listed in “Attaching a
PC or terminal to the Console port or Ethernet port” on page 24, make sure the terminal emulation session is
running on the same serial port you attached to the Console port.
If you see this prompt (PowerConnect>), you are now connected to the system and can display the status of the
modules using the CLI. Enter the following command at any CLI level:

Assigning passwords
NOTE
NOTE
NOTE
By default, the PowerConnect B-MLXe Series CLI is not protected by passwords. To secure CLI access, Dell strongly
recommends assigning passwords.
The CLI contains the following access levels:
•
Privileged EXEC – This level is also called the Enable level and can be secured by a password. From this level you
can manage files on the management module flash memory or a PCMCIA flash card in the management module
slots 1 or 2, save the system configuration to flash memory, and clear caches.
•
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.
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.
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:
PowerConnect> enable
PowerConnect#
2. Access the CONFIG level of the CLI by entering the following command:
PowerConnect# configure terminal
PowerConnect(config)#
3. Enter the following command to set the super-user password:
PowerConnect(config)# enable super-user-password <text>
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:
PowerConnect(config)# enable port-config-password <text>
PowerConnect(config)# enable read-only-password <text>
If you forget your super-user password, see the Release Notes.
The read-only--password and the port-config password should be difference from the super-user password.
Passwords can be up to 48 characters long.

Configuring IP addresses
The PowerConnect B-MLXe Series implement separate data and control planes. This architecture affects how you
assign IP addresses. Tabl e 3 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.
TABLE 3
Interface Associated physical port Out of band or in band
Assigning IP addresses
Management interface Ethernet 10/100/1000 port on active
or redundant management module
Any interface over which user packets are routed Any interface module port In band
Any virtual interface over which user packets are routed Any interface port In band

This section describes the following:
•
PowerConnect B-MLXe Series support of sub-net masks
•
How to assign an IP address to a management interface
•
How to assign an IP address to an interface or virtual interface over which user packets are routed
Out of band
Support of subnet masks
The PowerConnect B-MLXe Series supports both classical IP network masks (Class A, B, and C subnet masks, and so
on) and Classless Interdomain Routing (CIDR) network prefix masks.
•
To enter a classical network mask, enter the mask in IP address format. For example, enter
“209.157.22.99 255.255.255.0” for an IP address with a Class-C subnet mask.
•
To enter a prefix number for a network mask, enter a forward slash (/) and the number of bits in the mask
immediately after the IP address. For example, enter “209.157.22.99/24” for an IP address that has a network
mask with 24 significant (“mask”) bits.
Assigning an IP address to a management interface
Instead of assigning a global IP address to the B-MLXe for system management purposes, you must assign an IP
address to the active management module. If the active management module becomes unavailable and the
redundant module becomes the active module, the IP address is automatically assigned to the new active
management module.
For example, to assign the IP address 10.0.1.1 to the management interface, do the following:
1. At the opening CLI prompt, enter enable:
PowerConnect> enable
2. Enter the following command at the Privileged EXEC level prompt (for example, PowerConnect#), then press
Enter. This command erases the factory test configuration if still present:
PowerConnect# erase startup-config
