Before You Connect to the Network: Mounting Kit Instructions

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.

Installing the Switch Without the 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.

1. Set the switch on a flat surface and check for proper ventilation.
   
   

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.

2. Attach the rubber feet on the marked locations on the bottom of the chassis.
   
   

The rubber feet, although optional, are recommended to keep the unit from slipping.

Installing the Switch in a Rack

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.

1. Use the supplied screws to attach a mounting bracket to each side of the switch.
   
   
2. Align the holes in the mounting bracket with the holes in the rack.
   
   
3. Insert and tighten two screws through each of the mounting brackets.
   
   

External Redundant Power System

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.

Connecting the Console Port

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:

• A terminal or a computer with both a serial port and the ability to emulate a terminal
  
  
• A null modem or crossover RS-232 cable with a female DB-9 connector for the console port on the switch
  
  

To connect a terminal to the console port:

1. Connect the female connector of the RS-232 cable directly to the console port on the switch, and tighten the captive retaining screws.
   
   
2. Connect the other end of the cable to a terminal or to the serial connector of a computer running terminal emulation software.
   
   

Set the terminal emulation software as follows:

1. Select the appropriate serial port (COM port 1 or COM port 2).
   
   
2. Set the data rate to 9600 baud.
   
   
3. Set the data format to 8 data bits, 1 stop bit, and no parity.
   
   
4. Set flow control to none.
   
   
5. Under Properties, select VT100 for Emulation mode.
   
   
6. Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that you select Terminal keys (not Windows keys).
   
   

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.

3. After you have correctly set up the terminal, plug the power cable into the power receptacle on the back of the switch. The boot sequence appears in the terminal.
   
   
4. After the boot sequence completes, the console login screen displays. If you have not logged into the command line interface (CLI) program, the default user names are admin and guest, and the corresponding passwords are admin and guest.
   
   
   • If you log in as guest, the CLI displays the Console> prompt to indicate that you are using the CLI in normal access (Normal Exec) mode.
     
     
   • If you log in as admin, the CLI displays the Console# prompt to indicate that you are using the CLI in privileged access (Privileged Exec) mode.
     
     
5. Enter the commands to complete your desired tasks. Many commands require Privileged Exec-level access.
   
   

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.

6. When you have completed your tasks, exit the session with the Quit command.
   
   

Password Protection

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

Username: admin

Password:

CLI session with the PowerConnect 5224 is opened.

To end the CLI session, enter [Exit].

Console#

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.

1. At the CLI login prompt, enter admin as the user name and password for the Privileged Exec level. Press <Enter>.
   
   
2. Type configure and press <Enter>.
   
   

NOTE: Passwords are case sensitive.

3. To set the Normal Exec level password, type username guest password 0 password, where password is your new password (up to eight characters). Press <Enter>.
   
   
4. To set the Privileged Exec level password, type username admin password 0 password, where password is your new password (up to eight characters). Press <Enter>.
   
   
5. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
   
   

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.

SNMP Settings

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:

• public — Allows authorized management stations to retrieve MIB objects.
  
  
• private — Allows authorized management stations to retrieve and modify MIB objects.
  
  

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:

1. If you are not already in the Privileged Exec level global configuration mode, type configure and press <Enter>.
   
   
2. To delete the private community string, type no snmp-server community private and then press <Enter>.
   
   
3. To delete the public community string, type no snmp-server community public and then press <Enter>.
   
   
4. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
   
   

If you do intend to utilize SNMP, change the default community strings to prevent unauthorized access to the switch:

1. If you are not already in the Privileged Exec level global configuration mode, type configure and press <Enter>.
   
   
2. To delete the existing private community string, type no snmp- server community private and then press <Enter>.
   
   
3. Type snmp-server community string rw, where string is your new community string (case sensitive) for read-write access. Press <Enter>.
   
   
4. To delete the existing public community string, type no snmp- server community public and then press <Enter>
   
   
5. Type snmp-server community string ro, where string is your new community string (case sensitive) for read-only access. Press <Enter>.
   
   
6. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
   
   

IP Address Assignment

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:

1. From the Privileged Exec or Normal Exec level mode, type show ip interface and press <Enter>.
   
   

The assigned IP address and subnet mask displays.

2. From the Privileged Exec mode, type show ip redirects to display the assigned gateway IP address. Press <Enter>.
   
   

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

Console#

Before you can assign a static IP address to the switch, you must obtain the following information from your network administrator:

• IP address for the switch
  
  
• Default gateway for the network
  
  
• Network mask for the network
  
  

To assign a static IP address to the switch:

1. From the Privileged Exec level global configuration mode prompt, type interface vlan 1 to access the interface-configuration mode. Press <Enter>.
   
   
2. Type ip address ip-address netmask, where ip-address is the switch IP address and netmask is the network mask for the network.
   
   
3. Type exit to return to the global configuration mode prompt. Press <Enter>.
   
   
4. To set the IP address of the default gateway for the network to which the switch belongs, type ip default-gateway gateway, where gateway is the IP address of the default gateway. Press <Enter>.
   
   
5. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
   
   

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-if)# exit

Console(config)# ip default-gateway 192.168.1.254

Console(config)#

To configure the switch for DHCP or BOOTP:

1. From the Privileged Exec level global configuration mode prompt, type interface vlan 1 to access the interface-configuration mode. Press <Enter>.
   
   
2. At the next prompt, use one of the following commands:
   
   
   • To obtain IP settings through DHCP, type ip address dhcp
     
     
   • To obtain IP setting through BOOTP, type ip address bootp
     
     
3. Press <Enter>.
   
   
4. To save your configuration changes, type copy running-config startup-config, and then press <Enter>.
   
   

Connecting Devices to the Switch

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:

1. Use your cabling requirements to select an appropriate SFP transceiver type.
   
   
2. Insert the SFP transceiver (sold separately) into the SFP transceiver slot. The slot's LED indicator turns on to confirm that it is correctly installed.
   
   
3. Use the appropriate network cabling to connect a device to the connectors on the SFP transceiver.
   
   

NOTICE: When the SFP transceiver acquires a link, the associated integrated 10/100/1000BASE-T port is disabled.
