Dell PowerConnect 5224 Systems User's Guide
Before you begin installing the switch, confirm that your package contains the following items:
|NOTICE: Do not connect the switch to the network until you have established the correct Internet Protocol (IP) settings.|
Before you connect to the network, you must install the switch on a flat surface or in a rack, set up a terminal emulation program, plug in the power cord, and then set up a password and IP address.
The switch is supplied with rubber feet for stationing it on a flat surface and mounting brackets and screws for mounting the switch in a rack.
Install the switch on a level surface that can safely support the weight of the switch and its attached cables. The switch must have adequate space for ventilation and for accessing cable connectors.
Allow at least 2 inches (5.1 centimeters [cm]) on each side of the switch and 5 inches (12.7 cm) at the back for the power cable.
The rubber feet, although optional, are recommended to keep the unit from slipping.
You can install the switch in most standard 19-inch (48.3-cm) racks.
|NOTE: For racks that are not prethreaded, cage nuts are provided.|
The switch supports the Dell PowerConnect RPS-600 external redundant power system.
|NOTE: See the RPS-600 documentation for more information.|
|CAUTION: Do not use the switch with any redundant power system other than the Dell PowerConnect RPS-600.|
The switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and configuring the switch. This port is a male DB-9 connector, implemented as a data terminal equipment (DTE) connection.
To use the console port, you need the following equipment:
To connect a terminal to the console port:
Set the terminal emulation software as follows:
|NOTICE: When you use HyperTerminal with the Microsoft® Windows® 2000 operating system, ensure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 allows you to use arrow keys in HyperTerminal's VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.|
CLI commands for most common tasks are provided in "Management Interface." See the Command Line Reference on the documentation CD for a list of all commands and additional information on using the CLI.
To proceed through the CLI initial login screen, you must enter a password. If you have not logged into the CLI program, the default user names are admin and guest, and the corresponding passwords are admin and guest. If you log in as guest, you have access to the Normal Exec level. If you log in as admin, you have access to the Privileged Exec level.
User Access Verification
CLI session with the PowerConnect 5224 is opened.
To end the CLI session, enter [Exit].
After your initial login, define new passwords for both default user names to prevent unauthorized access to the switch, and record the passwords for future reference.
|NOTE: Passwords are case sensitive.|
|NOTICE: CLI configuration commands only modify the running configuration file and are not saved when the switch is rebooted. To save all your configuration changes in nonvolatile storage, you must use the copy command to copy the running configuration file to the startup configuration.|
Simple Network Management Protocol (SNMP) is a protocol designed specifically for managing devices on a network. Network equipment, such as hubs, switches, and routers, use SNMP to configure system features for proper operation, as well as to monitor their performance and detect potential problems.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network.
The PowerConnect 5224 switch includes an on-board SNMP agent that monitors the status of the switch hardware, as well as the traffic passing through the ports. A computer on the network running SNMP-based management software, called a Network Management Station (NMS), can be used to access this information. Access rights to the SNMP agent are controlled by community strings. To communicate with the switch, the NMS must first submit a valid community string for authentication.
The default community strings for the switch are:
If you do not intend to utilize SNMP, delete both of the default community strings. SNMP management access to the switch is disabled if no community strings exist. To delete the strings:
If you do intend to utilize SNMP, change the default community strings to prevent unauthorized access to the switch:
You must assign an IP address to the switch to gain management access over the network. You may also need to a establish a default gateway between the switch and management stations that exist on another network segment. You can statically configure a specific IP address or direct the switch to obtain an address from a Boot Protocol (BOOTP) or Dynamic Host Configuration Protocol (DHCP) server when it is powered on. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format is not accepted by the CLI program.
|NOTICE: By default, the IP address is assigned to VLAN 1 through DHCP.|
If you select the bootp or dhcp option, IP is enabled but does not function until a BOOTP or DHCP reply has been received. Requests are broadcast periodically by the switch in an effort to learn its IP address. (BOOTP and DHCP values can include the IP address, default gateway, and subnet mask).
To display assigned IP settings using the CLI:
The assigned IP address and subnet mask displays.
The following example displays IP settings assigned by bootp or dhcp using the CLI.
Console#show ip interface
IP address and netmask: 10.1.0.1 255.255.252.0 on VLAN 1,
and address mode: User specified.
Console# show ip redirects
ip default gateway 10.1.0.254
Before you can assign a static IP address to the switch, you must obtain the following information from your network administrator:
To assign a static IP address to the switch:
|NOTICE: Only one VLAN can be assigned an IP address. If you assign an address to any other VLAN, the new address overrides the original IP address.|
The following example shows how to set a static IP address using the CLI.
Console(config)# interface vlan 1
Console(config-if)# ip address 192.168.1.5 255.255.255.0
Console(config)# ip default-gateway 192.168.1.254
To configure the switch for DHCP or BOOTP:
After you assign IP addresses to the switch, you can connect devices to the RJ-45 connectors on the switch.
|NOTICE: If autonegotiation is disabled for an RJ-45 port, the auto- MDI/MDI-X pin signal configuration is also disabled.|
To connect a device to an SFP transceiver port:
|NOTICE: When the SFP transceiver acquires a link, the associated integrated 10/100/1000BASE-T port is disabled.|
