In non-TCP/IP environments, you communicate with the switch from a remote location (Omega Remote) by entering its pre-configured MAC address, located below the RS232 port on the front panel (Figure1-1).

At a later time, you can assign an easy-to-remember switch name through the System Administration menus (described later in Chapter 3 in the section,

5HPRWH#0DQDJHPHQW#,Q#7&32,3#1HWZRUNV

In a TCP/IP network, the switch requires a set of IP parameters, such as a unique IP address and subnet mask, for communication. The switch obtains its IP parameters in one of the following ways:

If you have BootP or DHCP, the switch can obtain its IP parameters from the BootP or DHCP server during startups. In this case, you simply connect the switch to the network.

The function of the BootP or DHCP utility within an IP server is to provide IP parameters, including an IP address, to the switch. Whenever you reset or power on and off the switch, the switch transmits a request packet to the server every three seconds to obtain the required IP parameters. The switch makes three request attempts.

If the requesting switch does not receive a BootP or DHCP response after the third request, it will operate with a computed pseudo IP address based on the switch’s MAC address.

If the switch receives a response from the BootP or DHCP server, the switch extracts the IP address, Subnet Mask, or Gateway/Router address and uses these parameters to configure itself until the next power-on or reset. Additionally, if the BootP response packet specifies a filename and a TFTP host address, then the switch sends a TFTP

request to the specified host using the specified filename.

This initiates a TFTP download of operating software and allows you to maintain the downloaded software on your server.

If you do not quit Omega from a local session, future Telnet sessions to the switch will be blocked.

If you are currently in a Telnet session, you must additionally disconnect Telnet after quitting Omega. Otherwise, future Telnet sessions to the switch will be blocked.

You may configure a timeout value so that the switch automatically disconnects Telnet sessions after a period of inactivity. See Chapter 3, section on

Configuring a Timeout Value

on page3-13, for the

procedures.

Skip this section if you have a non-TCP/IP network or if you have TCP/IP but use a BootP or DHCP server to provide IP parameters.

$70654#8VHU·V#*XLGH

This procedure provides the

minimum

IP configurations you need to enter so that the switch can be part of your TCP/IP network. Assigning a unique IP address to the switch provides an advantage: the switch uses the same IP parameters despite resets and power cycles.

1. Select System configuration>IP Parameters from the

main menu.

2. Select IP address, press

to insert a type-in field, and

enter a unique IP address for the switch.

3. Select Subnet mask and enter the switch’s subnet mask.

4. Select Gateway address and enter the address if you are

sending packets to another IP network. The gateway address is the router that can forward packets to

the other IP networks.

Once the switch has an IP address, you may initiate Omega sessions to it via Telnet or a web browser. Note that you can only have one Telnet session operating at any one time. The session can be either inbound or outbound. If y ou ha v e an inboun d session to Omega, yo u do not have the option of starting a new session (outbound connection). Therefore, if you are already using Telnet, the Omega option Connect to a remote system will not be available (described in detail in Chapter 4,

Monitoring and Administration

). In addition, a local RS232 connection blocks a T elnet session and vice versa.

For more on IP parameter configuration, go to Chapter 3 and refer to the section,

IP Parameters

on page3-2.

Note

For non-IP environments, you can use MAC addresses to connect to remote Allied Telesyn switches as long as there are no routers between the two switches. If you have assigned unique names, you may use these in place of MAC or IP addresses.
