Control features

Each device front panel includes the following control features:

• Serial management interface (the DB9 port labeled Console)

PowerConnect B-FCX Switch Hardware Installation Guide 3 53-1002267-01

Hardware features

• Out-of-band RJ45 management Interface

Serial management interface (DB9 Console port)

The serial management interface allows you to configure and manage the device using a third-party terminal emulation application on a directly-connected PC. A straight-through EIA or TIA DB9 serial cable (M or F) ships with the device. The serial management interface (the DB9 Console port) is located in the left corner of the front panel.

Out-of-band RJ45 management interface

The out-of-band RJ45 management interface enables you to configure and manage the device using a third-party terminal emulation application on a directly-connected PC.

Network interfaces for PowerConnect B-FCX624s and PowerConnect B-FCX648s

PowerConnect B-FCX devices contain the following interfaces:

• 10/100/1000 Mbps ports with RJ45 copper connectors

• 100/1000 Mbps ports with mini-GBIC slots for SFP MSA-compliant fiber transceivers

• Optional 2-port 10Gbps Ethernet XFP module

• CX4 stacking ports

Network interfaces for PowerConnect B-FCX624 and PowerConnect B-FCX648

PowerConnect B-FCX devices contain the following interfaces:

• 10/100/1000 ports with RJ45 copper connectors

• 100/1000 ports with mini-GBIC slots for MSA-compliant SFP transceivers

• Optional 4-port 1Gbps Ethernet SFP module

• Optional 4-port 10Gbps Ethernet SFP+ module

PowerConnect B-FCX 10/100/1000 BASE-T ports All PowerConnect B-FCX devices except for the fiber models contain 24 or 48 RJ45 ports that

operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports support automatic MDI or MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In addition, it is ideal and preferred to use straight-through cable for switch-to-switch connections.

Each of these ports supports auto-negotiation, so the optimum transmission mode (half or full duplex), and the data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of the port can be configured manually.

Combination ports PowerConnect B-FCX devices contain four combination ports, which are four Small Form Factor

Pluggable (SFP) network interfaces (1F~4F) that are shared with four of the RJ45 ports (ports 1~4). In the default configuration, if an SFP transceiver is installed in a slot and has a valid link on its port, the associated RJ45 port is disabled and cannot be used. The switch can also be configured to force the use of a combination RJ45 port or SFP slot, as required.

Connecting devices in a stack

PowerConnect B-FCX624s and PowerConnect B-FCX648s devices

Figure 5 shows how the stack cables are connected between switches in a stack. The connection is

based on 10G/16G Gigabit Ethernet, using CX4 cables. PowerConnect B-FCX devices support linear and ring stack topologies, and can also operate as standalone devices.

PowerConnect B-FCX Switch Hardware Installation Guide 21 53-1002267-01

Preparing the installation site

In a linear stack topology there is a single stack cable connection between each switch that carries two-way communications across the stack. In ring stack topology, an extra cable is connected between the top and bottom switches forming a “ring” or “closed-loop.” The closed-loop cable provides a redundant path for the stack link, so if one link fails, stack communications can be maintained. Figure 5 illustrates a ring-topology stacking configuration.

You can form a stack containing up to eight PowerConnect B-FCX units. To connect switches in a stack, perform the following steps:

1. Plug one end of a stack cable into one of the CX4 stacking ports of the top unit.

2. Plug the other end of the stack cable into one of the stacking ports of the next unit.

3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting with a stacking

NOTE

To turn the system off, simply unplug the power cable or cables.

NOTE

The socket should be installed near the equipment and should be easily accessible.

If the outlet is not rated 115/120V, stop and get the appropriate cable for the outlet.

Attaching a PC or terminal

To assign an IP address, you must have access to the Command Line Interface (CLI). The CLI is a text-based interface that can be accessed through a direct serial connection to the device and through Telnet connections. The CLI is described in detail in the PowerConnect B-FCX Series Configuration Guide.

Access the CLI by attaching a serial cable to the Console port. After you assign an IP address, you can access the system through Telnet, the Web management interface, or Brocade Network Advisor.

Attaching a PC or terminal

Use the following steps to attach a management station to the serial port.

1. Connect a PC or terminal to the serial port of the system using a straight-through cable. The serial port has a male DB-9 connector. See Figure 26.

You need to run a terminal emulation program on the PC.

2. Launch the terminal emulation program and set the following session parameters:

• Baud: 9600 bps

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: None

The EIA or TIA 232 serial communication port serves as a connection point for management by a PC or SNMP workstation. Dell devices come with a standard male DB-9 connector, shown in

Figure 26.

Checking Network Devices and Testing Connectivity

The procedures in this manual are for qualified service personnel.

Assigning permanent passwords

By default, the CLI is not protected by passwords. To secure CLI access, Dell strongly recommends assigning passwords. See the PowerConnect B-FCX Series Configuration Guide.

You cannot assign a password using the Web Management Interface. You can assign passwords using Brocade Network Advisor if an enable password for a Super User has been configured on the device.

The CLI contains the following access levels:

• User EXEC – The level you enter when you first start a CLI session. At this level, you can view

some system information but you cannot configure system or port parameters.

• 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 flash module, save the system configuration to flash, and clear caches at this level.

• CONFIG – The configuration level. This level lets you configure the system IP address and

configure switching and 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.

PowerConnect B-FCX Switch Hardware Installation Guide 33 53-1002267-01

Assigning permanent passwords

NOTE

Setting passwords

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

PowerConnect> enable

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, refer to “Recovering from a lost password” on page 34.

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

Passwords can be up to 32 characters long.

Recovering from a lost password

By default, the CLI does not require passwords. However, if someone has configured a password for the device but the password has been lost, you can regain super user access to the device using the following procedure.

Recovery from a lost password requires direct access to the serial port and a system reset.

Use the following procedure to recover from a lost password.

1. Start a CLI session over the serial interface to the Dell device.

2. Reboot the device.

3. While the system is booting, before the initial system prompt appears, enter b to enter the boot monitor mode.

4. Enter no password at the prompt. (You cannot abbreviate this command.)

5. Enter boot system flash primary at the prompt. This command causes the device to bypass the system password check.

After the console prompt reappears, assign a new password.

Configuring IP addresses

CAUTION

NOTE

You must configure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces.

Dell devices support 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.

By default, the CLI displays network masks in classical IP address format (example:

255.255.255.0). You can change the display to the prefix format. See the PowerConnect B-FCX

Series Configuration Guide.

Devices running Layer 2 software

Use the following procedure to configure an IP Address on a device running Layer 2 software.

Configuring IP addresses

1. At the opening CLI prompt, enter enable.

PowerConnect> enable

2. Enter the following command at the Privileged EXEC level prompt (for example, PowerConnect present:

PowerConnect# erase startup-config

Use the erase startup-config command only for new systems. If you enter this command on a system you have already configured, the command erases the configuration. If you accidentally do erase the configuration on a configured system, enter the write memory command to save the running configuration to the startup-config file.

3. Access the configuration level of the CLI by entering the following command:

PowerConnect# configure terminal (Privileged EXEC Level) PowerConnect(config)# (Global CONFIG Level)

4. Configure the IP address and mask for the switch.

PowerConnect(config)# ip address 192.22.3.44 255.255.255.0

5. Set a default gateway address for the switch.

PowerConnect(config)# ip default-gateway 192.22.3.1

#), then press Enter. This command erases the factory test configuration if still

You do not need to assign a default gateway address for single subnet networks.

NOTE

Syntax: [no] ip address <ip-addr> <ip-mask>

Syntax: [no] ip address <ip-addr>/<mask-bits>

Devices running Layer 3 software

Before attaching equipment to a Layer 3 Switch, you must assign an interface IP address to the subnet on which the router will be located. You must use the serial connection to assign the first IP address. For subsequent addresses, you also can use the CLI through Telnet or the Web management interface.

By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table.

The following procedure shows how to add an IP address and mask to a router port.

1. At the opening CLI prompt, enter enable.

PowerConnect> enable

2. Enter the following command at the CLI Privileged EXEC level prompt, then press Enter. This command erases the factory test configuration if still present:

PowerConnect# erase startup-config

3. Access the configuration level of the CLI by entering the following command:

PowerConnect# configure terminalPrivileged EXEC Level PowerConnect(config)#Global CONFIG Level

4. Configure the IP addresses and mask addresses for the interfaces on the router.

PowerConnect(config)# int e 2 PowerConnect(config-if-e1000-2)# ip address 192.22.3.44 255.255.255.0

You can use the syntax ip address <ip-addr>/<mask-bits> if you know the subnet mask length. In the above example, you could enter ip address 192.22.3.44/24.

Syntax: enable [<password>]

Syntax: configure terminal

Syntax: [no] ip address <ip-addr> <ip-mask> [secondary]

Syntax: [no] ip address <ip-addr>/<mask-bits> [secondary]

36 PowerConnect B-FCX Switch Hardware Installation Guide

53-1002267-01

Configuring IP addresses

NOTE

Use the secondary parameter if you have already configured an IP address within the same subnet on the interface.

Configuring IP parameters for devices running Layer 3 software

This section describes how to configure IP parameters for devices running Layer 3 software.

Configuring IP addresses You can configure an IP address on the following types of Layer 3 switch interfaces:

• Ethernet port

• Virtual routing interface (also called a Virtual Ethernet or “VE”)

• Loopback interface

By default, you can have up to 24 IP addresses on each interface, but you can increase this number to 128 IP addresses.

Once you configure a virtual routing interface on a VLAN, you cannot configure Layer 3 interface parameters on individual ports in the VLAN. Instead, you must configure the parameters on the virtual routing interface itself.

Dell devices support 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 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 bits (ones).

By default, the CLI displays network masks in classical IP address format (for example:

255.255.255.0). You can change the display to prefix format.

Assigning an IP address to an Ethernet port Enter the following commands to assign an IP address to port 1/1/1.

PowerConnect(config)# interface ethernet 1/1/1 PowerConnect(config-if-1/1/1)# ip address 192.45.6.1 255.255.255.0

You also can enter the IP address and mask in CIDR format, as follows:

PowerConnect(config-if-1/1/1)# ip address 192.45.6.1/24

Syntax: [no] ip address <ip-addr> <ip-mask>

Syntax: [no] ip address <ip-addr>/<mask-bits>

Assigning an IP address to a loopback interface Loopback interfaces are always up, regardless of the states of physical interfaces. They can add

stability to the network because they are not subject to route flap problems that can occur due to unstable links between a Layer 3 Switch and other devices. You can configure up to four loopback interfaces on a Layer 3 switch.

PowerConnect B-FCX Switch Hardware Installation Guide 37 53-1002267-01

Configuring IP addresses

NOTE

You can add up to 24 IP addresses to each loopback interface.

If you configure the Dellswitch to use a loopback interface to communicate with a BGP4 neighbor, you must also configure a loopback interface on the neighbor and configure the neighbor to use that loopback interface to communicate with theDell switch.

To add a loopback interface, enter commands such as those shown in the following example:

PowerConnect(config)# exit PowerConnect(config)# int loopback 1 PowerConnect(config-lbif-1)# ip address 10.0.0.1/24

Syntax: interface loopback <num>

The <num> parameter specifies the virtual interface number. You can specify from 1 to the maximum number of virtual interfaces supported on the device. To display the maximum number of virtual interfaces supported on the device, enter the show default values command. The maximum is listed in the System Parameters section, in the Current column of the virtual-interface row.

Assigning an IP address to a virtual routing interface A virtual interface is a logical port associated with a Layer 3 Virtual LAN (VLAN) configured on a

Layer 3 switch. You can configure routing parameters on the virtual interface to enable the Layer 3 switch to route protocol traffic from one Layer 3 VLAN to the other, without using an external router.

This section describes how to configure an IP address on a virtual interface.

The switch uses the lowest MAC address on the device (the MAC address of port 1 or 1/1/1) as the MAC address for all ports within all virtual interfaces you configure on the device.

Enter commands similar to the following to add a virtual interface to a VLAN and configure an IP address on the interface.

PowerConnect(config)# vlan 2 name IP-Subnet_1.1.2.1/24 PowerConnect(config-vlan-2)# untag 1/1/1 to 1/1/4 PowerConnect(config-vlan-2)# router-interface ve1 PowerConnect(config-vlan-2)# interface ve1 PowerConnect(config-vif-1)# ip address 1.1.2.1/24

The first two commands in this example create a Layer 3 protocol-based VLAN name “IP-Subnet_1.1.2.1/24” and add a range of untagged ports to the VLAN. The router-interface command creates virtual interface 1 as the routing interface for the VLAN. The last two commands change to the interface configuration level for the virtual interface and assign an IP address to the interface.

Syntax: router-interface ve <num>

Syntax: interface ve <num>

Deleting an IP address

Enter a command similar to the following to delete an IP address.

PowerConnect(config-if-1/1/1)# no ip address 1.1.2.1

This command deletes IP address 1.1.2.1. You do not need to enter the subnet mask.

Cable specifications

Refer to “Cable specifications” on page 62 for cable lengths and types.

Connecting to Ethernet or fast Ethernet hubs

For copper connections to Ethernet hubs, a 10/100BaseTX or 1000BaseT switch, or another Dell device, a crossover cable is required (Figure 32 and Figure 33). If the hub is equipped with an uplink port, it will require a straight-through cable instead of a crossover cable.

The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the connection between two 1000Base-T ports. In this case a straight-through cable may work just as well as a crossover cable. For more information about this feature, see the PowerConnect B-FCX Series Configuration Guide.

Fiber cabling is required for direct attachment to Gigabit NICs or switches and routers through fiber ports. Refer to “Connecting a network device to a fiber port” on page 40.

Automatic MDI or MDIX detection

All 10/100 and Gbps Ethernet Copper ports on the devices support automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all 10/100 and Gigabit copper ports by default. For each port, you can disable auto MDI or MDIX, designate the port as an MDI port, or designate the port as an MDIX port.

For more information about this feature and how configure it, refer to PowerConnect B-FCX Series Configuration Guide.

Connecting a network device to a fiber port

For direct attachment from the device to a Gbps NIC, switch, or router, using a fiber optic transceiver, you will need fiber cabling with an LC connector.

To connect the device to another network device using a fiber port, you must do the following tasks:

• Install a fiber optic transceiver (XFP, SFP, or SFP+)

• Cable the fiber optic transceiver

The following sections describe these tasks.

Tracing a route

To determine the path through which a Dell device can reach another device, enter a command similar to the following at any level of the CLI on the device.

PowerConnect> traceroute 192.33.4.7

Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]

[source-ip <ip addr>]

The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the Dell device displays up to two responses by default.

Troubleshooting network connections

• For the indicated port, verify that both ends of the cabling (at the device and the connected

device) are snug.

• Verify that the device and the connected device are both powered on and operating correctly.

PowerConnect B-FCX Switch Hardware Installation Guide 45 53-1002267-01

Troubleshooting network connections

• Verify that you have used the correct cable type for the connection:

- For twisted-pair connections to an end node, use straight-through cabling.

- For fiber optic connections, verify that the transmit port on the device is connected to the

receive port on the connected device, and that the receive port on the device is connected to the transmit port on the connected device.

• Use the CLI to verify that the port has not been disabled through a configuration change. If you

have configured an IP address on the device, you also can use the Web management interface or Brocade Network Advisor.

• If the other procedures don’t resolve the problem, try using a different port or a different cable.

Using Virtual Cable Testing to diagnose a cable

These devices support Virtual Cable Test (VCT) technology. VCT technology enables you to diagnose a conductor (wire or cable) by sending a pulsed signal into the conductor, then examining the reflection of that pulse. This method of cable analysis is referred to as Time Domain Reflectometry (TDR). By examining the reflection, the device can detect and report cable statistics such as local and remote link pair, cable length, and link status.

Configuration notes

• This feature is supported on copper ports only. It is not supported on fiber ports.

• The port to which the cable is connected must be enabled when you issue the command to

diagnose the cable. If the port is disabled, the command is rejected.

• If the port is operating at 100 Mbps half-duplex, the TDR test on one pair will fail.

• If the remote pair is set to forced 100 Mbps, any change in MDI or MDIX may cause the device

to interpret the Multilevel Threshold-3 (MLT-3) as a reflected pulse, in which case, the device will report a faulty condition. In this case, Dell recommends that you run the TDR test a few times for accurate results.

Command syntax

To diagnose a cable using TDR, enter a command such as the following at the Privileged EXEC level of the CLI.

PowerConnect# phy cable-diag tdr 1/1/1

This command diagnoses the cable attached to port 1/1/1.

Syntax: phy cable-diag tdr <port-num>

Viewing the results of the cable analysis

To display the results of the cable analysis, enter a command similar to the following at the Privileged EXEC level of the CLI.

PowerConnect# show cable-diag tdr 1/1/1

Digital optical monitoring

You can configure your device to monitor optical transceivers in the system, either globally or by specified port. When this feature is enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specified ports. Console messages and syslog messages are sent when optical operating conditions fall below or rise above the XFP, SFP, and SFP+ manufacturer’s recommended thresholds. For more information about digital optical monitoring, refer to PowerConnect B-FCX Series Configuration Guide.

CAUTION

Managing the PowerConnect B-FCX Hardware

The procedures in this manual are for qualified service personnel.

Managing temperature settings

This section describes how to display temperature settings on the device and how to change the temperature warning and shutdown levels.

Using the temperature sensor

The device ships with three built-in temperature sensors that cause the device to generate a Syslog message and SNMP trap if the temperature exceeds a specified warning level or shutdown level. If the device temperature exceeds the safe threshold (shutdown level), the device will reboot.

The software reads the temperature sensors based on the device poll time, which is by default 60 seconds. If the temperature equals or exceeds the shutdown temperature for five consecutive polls by the software, the software will reboot the device to prevent damage.

You can use the CLI or Web management interface to perform the following tasks:

• Display the temperature of the device

• Change the warning and shutdown temperature levels

• Change the device poll time

Displaying the temperature

By default, the software polls the temperature sensor every 60 seconds to get the current temperature. This poll rate is controlled by the device poll time, which also controls how often the software polls other system components.

To display the temperature of a device, enter the show chassis command at any level of the CLI.

PowerConnect# show chassis The stack unit 1 chassis info: Power supply 1 (NA - AC - Regular) present, status ok Power supply 2 not present Fan ok, speed (auto):
