www.dell.com | support.dell.com Facing the rear of an S-Series unit, stack-port are numbered from left to right, beginning with the highest Ethernet port number (n) plus 1. For example, for a 48-port unit with two 12-Gigabyte stacking modules, the stack-ports are 49, 50, 51, and 52, starting from the left. To add a unit to an existing stack: Step 1 2 3 4 5 Task Command Syntax Verify that each unit has the same FTOS version prior to stacking them together. Pre-configure unit numbers for each unit so that the stacking is deterministic upon boot up. Configure the switch priority for each unit to make management unit selection deterministic. show version stack-unit renumber stack-unit priority Connect the units using stacking cables. Power the stack one unit at a time. Start with the management unit, then the standby, followed by each of the members in order of their assigned stack number (or the position in the stack you want each unit to take). Allow each unit to completely boot, and verify that the unit is detected by the stack manager, and then power the next unit. show system brief To display the status of the stacking ports, including the topology: Command Mode EXEC Privilege EXEC Privilege CONFIGURATION EXEC Privilege Task Display the stacking ports. Command Syntax show system stack-ports Command Mode EXEC Privilege The first example below shows a daisy-chain topology. The second example shows the same stack converted to a ring by connecting stack-port 2/51 to 0/51; you may rearrange the stacking cables without triggering a unit reset, so long as the stack manager is never disconnected from the stack.
