Management port
The Management port provides connectivity to your existing management network through
10/100/1000 copper ports that uses auto-sensing and auto-negotiating to determine the speed
(10 Mbps, 100 Mbps, or 1000 Mbps) and mode (full-duplex or half-duplex) of the port at the other
end of the link, and adjusts port speed accordingly. The Management port on the PowerConnect
B-Series TI24X supports RJ-45 copper connectors, auto MDI or MDIX detection, and has an RJ-45
unshielded twisted pair (UTP) connector.
This port interfaces with the CPU only and not the data plane.

Assigning permanent passwords
The procedures in this manual are intended for qualified service personnel.

This chapter provides the details for connecting network devices and checking network
connectivity.
By default, the CLI is not protected by passwords. To secure CLI access, Dell strongly recommends
assigning passwords.
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—Also called the Enable level, and can be secured by a password. At this level,
you can perform tasks such as manage files on the flash module, save the system
configuration to flash, and clear caches.
• CONFIG—This level lets you configure the system IP address, and switching and routing
features. To access the CONFIG mode, you must already be logged into the Privileged level of
the EXEC mode (the Enable level).
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.
Follow the steps 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
2. Access the CONFIG level of the CLI by entering the following command.
PowerConnect# configure terminal

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”.
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.
Follow the steps to recover from a lost password.
1. Start a CLI session over the serial interface to thePowerConnect 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.
6. 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. In addition, Dell routers require an IP
subnet address for the subnet in which you plan to place them in your network.
Dell PowerConnect devices support both classical IP network masks (Class A, B, and C subnet
masks, and so on) and Classless Interdomain Routing (CIDR) and network prefix masks as follows:
• 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. Referto the PowerConnect
B-Series TI24X Configuration Guide.
Configuring IP addresses

Devices running Layer 2 software
Follow the steps to configure an IP address on a device running Layer 2 software.
1. At the opening CLI prompt, enter enable.
PowerConnect> enable
2. Enter the following command at the Privileged EXEC level prompt (for example, PowerConnect
Switch#), then press Enter. This command erases the factory test configuration if still 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
You do not need to assign a default gateway address for single subnet networks.
Syntax: enable [<password>]

Connecting network devices
Dell PowerConnect devices support connections to routers, switches, and hubs from other vendors,
as well as other Dell PowerConnect devices.
Connectors and cable specifications
Refer to “Cable specifications” on page 53 for cable lengths and types supported on the
PowerConnect B-Series TI24X devices. For port pinouts, refer to “10/100/1000 Gigabit port
pinouts” on page 53.
Connecting to Ethernet or fast Ethernet hubs
For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another Dell
PowerConnect device, a crossover cable is required (Figure 10 and Figure 11). 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. Therefore, a crossover cable may not be required; a
straight-through cable may work as well. For more information about this feature, refer to the
PowerConnect B-Series TI24X Configuration Guide.

The 802.3ab standard calls for automatic negotiation of the connection between two 1000Base-T
ports. Consequently, a crossover cable may not be required; a straight-through cable may work as
well.
Connecting to workstations, servers, or routers
Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or
routers using network interface cards (NICs).
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”.
Automatic MDI or MDIX detection
All 10/100/1000 Copper ports on the Dell PowerConnect B-Series TI24X devices support
automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX)
detection. This feature is enabled on all 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.

Connecting a network device to a fiber port
For direct attachment from the Dell PowerConnect device to a Gigabit NIC, switch, or router, fiber
cabling with an LC connector is required.
To connect the Dell PowerConnect device to another network device using a fiber port, you must do
the following:
• Install a fiber optic module (SFP transceiver or mini-GBIC for Gigabit Ethernet ports, or SFP+
• Cable the fiber optic module
The following sections provide information about performing these tasks.
Installing a fiber optic module
You must install a fiber optic module (SFP or SFP+ transceiver) in each Gigabit Ethernet and
10-Gigabit Ethernet fiber port you want to use.
transceiver for 10-Gigabit Ethernet ports)
You can install a new fiber optic module in a port while the Dell PowerConnect device is powered on
and running.
To install a fiber optic module, you will need an ESD wrist strap.
For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
Follow the steps to install a fiber optic module.
1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface
(such as an equipment rack) to act as ground.
2. Remove the new module from its protective packaging.
3. Gently insert the fiber optic module into the port until the module clicks into place. The module
is keyed to prevent incorrect insertion.
Cabling a fiber optic module
Follow the steps to cable a fiber optic module.
1. Remove the protective covering from the fiber-optic port connectors and store the covering for
future use.
2. Before cabling a fiber optic module, Dell strongly recommends that the cable connectors and
the port connectors are cleaned thoroughly.
3. Gently insert the cable connector or connectors (a tab on each connector should face upward)
into the port connector or connectors until the tabs lock into place.
4. Observe the link and active LEDs to determine if the network connections are functioning
properly. Refer to Table 5 .

Fiber-optic connectors
NOTE
To avoid problems with the connection between the fiber optic module (SFP (mini-GBIC) or SFP+)
and the fiber cable connectors.
When not using an SFP or SFP+ connector, use the protective covering from the fiber-optic port
connectors.
Testing connectivity
After you install the network cables, you can test network connectivity to other devices by pinging
those devices. You also can observe the LEDs related to network connection and perform trace
routes.
Pinging an IP address
To verify that a PowerConnect B-Series TI24X device can reach another device through the network,
enter a command such as the following at any level of the CLI on the PowerConnect device.
PowerConnect> ping 192.33.4.7

You can do the following:
• Verify that the connection to the other
network device has been properly made.
Also, make certain that the other
network device is powered on and
operating correctly.
• Verify that the transmit port on the Dell
PowerConnect device is connected to the
receive port on the other network device,
and that the receive port on the Dell
PowerConnect device is connected to the
transmit port on the other network
device. If you are uncertain, remove the
two cable connectors from the port
connector and reinsert them in the port
connector, reversing their order.
• Dust may have accumulated in the cable
connector or port connector. For
information about cleaning the
connectors, refer to “Fiber-optic
connectors”.
• If the other actions don't resolve the
problem, try using a different port or a
different cable.

extended
period.
The port is not transmitting or receiving user
packets. You can do the following:
• Check the Link LED to make sure the link
is still established with the remote port.
If not, take the actions described in the
Meaning or Action column for the Link
LED.
• Verify that the port has not been
disabled through a configuration
change. You can use the CLI. If you have
configured an IP address on the device,
you also can use Brocade Network
Advisor.
If a problem persists after taking these actions, contact Dell technical support.

Tracing a route
To determine the path through which a Dell PowerConnect device can reach another device, enter a
command such as the following at any level of the CLI on the PowerConnect 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 Time-To-Live (TTL). In addition, if there are
multiple equal-cost routes to the destination, the Dell PowerConnect device displays up to three
responses by default.
Troubleshooting network connections
• For the indicated port, verify that both ends of the cabling (at the PowerConnect device and the
connected device) are snug.
• Verify that the PowerConnect device and the connected device are both powered on and
operating correctly.
• 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.
• Verify that the port has not been disabled through a configuration change. You can use the CLI.
If you have configured an IP address on the device, you also can use IronView Network
Manager.
• For copper ports, you can test the cable using Virtual Cable Testing (VCT). Refer to "Monitoring
Hardware Components" in the PowerConnect B-Series TI24X Configuration Guide.
• If the other procedures don't resolve the problem, try using a different port or a different cable.

Support for digital optical monitoring
You can configure your PowerConnect 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 SFP+ or
SFP manufacturer recommended thresholds. For more information about digital optical monitoring,
refer to the PowerConnect B-Series TI24X Configuration Guide.

Managing temperature settings
This section describes how to display temperature settings on the PowerConnect B-Series TI24X
and how to change the temperature warning levels.
Using the temperature sensor
The PowerConnect B-Series TI24X comes with two built-in temperature sensors; one at the air
intake, and the other at the exhaust (refer to Figure 25 on page 51). The temperature sensor at the
air intake monitors the incoming air temperature. The temperature sensor at the air exhaust
monitors the air temperature as it exits the device. The temperature sensors cause the device to
generate a Syslog message and SNMP trap if the temperature exceeds a specified warning level
The software reads the temperature sensors according to the device poll time, which is 60 seconds
by default. If the temperature equals or exceeds the warning temperature the software generates a
Syslog message and SNMP trap.
4
You can use the CLI to perform the following:
• “Displaying the temperature”
• “Changing the temperature warning level”
• “Changing the device temperature polling interval”
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.
The following shows an example output.
PowerConnect#show chassis
Power supply 1 (NA - NA - Regular) present, status ok
Power supply 2 not present
Fan 1 ok, speed (auto):
