LevelOne GSW-2692 manual Stack Operations, Remote Connections

Stack Operations 2

Remote Connections

Prior to accessing the switch’s onboard agent via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using a console connection, DHCP or BOOTP protocol.

The IP address for this switch is obtained via DHCP by default. To manually configure this address or enable dynamic address assignment via DHCP or BOOTP, see “Setting an IP Address” on page 2-5.

Note: This switch supports four concurrent Telnet/SSH sessions.

After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network. The onboard configuration program can be accessed using Telnet from any computer attached to the network. The switch can also be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above), or from a network computer using SNMP network management software.

Note: The onboard program only provides access to basic configuration functions. To access the full range of SNMP management functions, you must use SNMP-based network management software.

Stack Operations

Up to eight switches can be stacked together as described in the Installation Guide. One unit in the stack acts as the Master for configuration tasks and firmware upgrade. All of the other units function in Slave mode.

To configure any unit in the stack, first verify the unit number by counting down from the Master unit, and then select the appropriate unit number from the web or console management interface.

Selecting the Stack Master

Note the following points about unit numbering:

•When the stack is initially powered on, the Master unit is designated as unit 1. The stack is simply numbered from top to bottom, with the first unit in the stack designated at unit 1. This unit identification number can be selected on the front panel graphic of the web interface, or from the CLI.

•If more than one stack Master is selected using the Master push button on the switch’s front panel, the stack will not function.

•If any unit fails, the stack will not function. You must replace the failed unit, and reconnect the stacking cables to restore a ring topology.

•If a unit in the stack fails or is removed from the stack, the unit numbers will not change. This means that when you replace a unit in the stack, the original configuration for the failed unit will be restored to the replacement unit.
