Chapter 4 Chapter 4: Configuration Using the Console Interface Overview The Switch features a menu-driven console interface that lets you perform basic switch configuration and easily manage your network. To use the console interface, you either run the HyperTerminal application to configure a serial connection through the Switch’s console port, or run a telnet session over an Ethernet connection.
Chapter 4 How to Use the Console Interface The Console Interface consists of a hierarchical series of menu screens and settings screens. Each menu displays a list of options. Selecting an option brings up a settings screen where you can configure the relevant settings. To select a menu option, either press the number of the option in the list (for example, press 5 to select Help from the Main Menu), or use the arrow keys to move up or down...

Appendix A About Gigabit Ethernet and Fiber Optic Cabling Appendix A: About Gigabit Ethernet and Fiber Optic Cabling Gigabit Ethernet Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with 100Mbps Fast Ethernet hardware.
Appendix B Appendix B: About Switch Stacking A switch may operate in one of two modes: Stack or Standalone. You can select either mode during software boot or using the web-based utility’s Setup > Summary screen, with the new mode taking effect after the unit is reset.
Appendix B the Console port, Telnet or Web-based Utility) and reset the units to make this assignment permanent. The unit that is assigned number 1 will act as the Master; this is indicated by the Stack Master LED on its front panel being lit amber.
Appendix B Stack Units Startup Process Whenever a unit in stack mode is initialized (powered up or rebooted) it goes through the same exact process, consisting of the following three steps: Master Discovery/Election. Unit ID allocation by the Master (including duplicate Unit ID conflict resolution) Unit/port configuration by the Master Master Discovery...
Appendix B If both duplicate units are in auto (self ordering) mode, • then the unit ID will be decided by the Mac address. The unit with the lower Mac will keep its unit ID. The other will be reassigned a new unit ID. If one of the duplicates is in auto (self ordering) •...
Appendix B If the incoming unit did not have an assigned Unit • ID (that is, it was in factory default mode), it will be assigned the lowest available Unit ID by the Master. It is strongly recommended that automatic assigned unit ID mode be used since it provides better resiliency to the stack.
Appendix B If the incoming unit already has an assigned Unit ID, • and that Unit ID is unused in the current stack, the incoming unit will keep its assigned Unit ID and the Master will apply to it any configuration relevant to that Unit ID.
Appendix B before the split. Since the Backup Master was not acting as a master prior to the split, it will initiate a topology database and port-learning process. Traffic might be halted for a short period of time until synchronization (unit and port configuration) is completed.
Appendix B It should be emphasized that when two stacks are combined, all of the configuration information for one of the stacks will be lost. Only the surviving master (after the discovery/election process completes) will maintain its configuration information. The best practice to combine two stacks is to reset the switches in one stack to the factory defaults and then add the switches as described in the “Adding Units to a Running Stack”...
