Make sure the terminal or PC you are using to make this connection is configured to match these settings.

If you are having problems making this connection on a PC, make sure the emulation is set to VT-100. If you still don’t see anything, try hitting <Ctrl> + r to refresh the screen.

Managing Switch Stacks

The Switch is designed to be stacked in stacks of up to six Switches, all managed as a single unit with a single IP address. The stack order is hardware-determined, that is, the unique MAC address of each Switch determines where the Switch stands in the stack order. This fact can be taken into account when you are placing the Switches in the equipment rack. Administrators may find it convenient to place the Switches in the rack in the same order they appear logically in the Switch stack. However, you also may prefer to override the auto-detect stack order feature if for example, you add Switches to a stack that is already in place. Regardless of the method used to determine Switch stack order, remember some important points:

•All management of all the Switches in the stack is done through the Master Switch.

•It is recommended that the Master Switch be used to uplink to the Ethernet backbone.

•If any Switch in the stack fails, all Switches will need to be rebooted upon correcting the failure.

•If a new Master is elected, all Switches in the stack must rebooted. This includes situations where the new Master is determined by MAC address, for example, if the original Master is removed from the stack.
