Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F

Stacking scenarios

The following sections present examples in a variety of areas concerning stacking the Dell
PowerConnect 8100 switches and provides step-by-step guidance using the CLI and Web UI, with screen
shots as a visual guide. Consult the table of contents above for a list of examples covered in this
document.

Each scenario in this document assumes that all Dell PowerConnect devices are using the same
firmware revision. It is also recommended that all devices are using the latest firmware version.

Note:

Upgrade the firmware to the latest revision on the units before stacking them.

Unless mentioned otherwise, all scenarios below assume the switches are using the static ports that are
hard-wired into the switches, and that no modules are installed providing additional ports.  However,
ports from an installed expansion module are supported and may be used for stacking.  The following
expansion modules are supported for stacking in the Dell PowerConnect series:
