Adding A Switch To The Stack - Dell PowerConnect 8024 User Configuration Manual

• If the stack master function is unassigned and there is another stack
master in the system then the switch changes its configured stack master
value to disabled.
• If the stack master function is enabled or unassigned and there is no other
stack master in the system, then the switch becomes stack master.
• If the stack master function is disabled, the unit remains a non-stack
master.
If the entire stack is powered OFF and ON again, the unit that was the stack
master before the reboot will remain the stack master after the stack resumes
operation.
You can manually set the unit number for the switch. To avoid unit-number
conflicts, one of the following scenarios takes place when you add a new
member to the stack:
• If the switch has a unit number that is already in use, then the unit that
you add to the stack changes its configured unit number to the lowest
unassigned unit number.
• If the switch you add does not have an assigned unit number, then the
switch sets its configured unit number to the lowest unassigned unit
number.
• If the unit number is configured and there are no other devices using the
unit number, then the switch starts using the configured unit number.
• If the switch detects that the maximum number of units already exist in
the stack making it unable to assign a unit number, then the switch sets its
unit number to

Adding a Switch to the Stack

When adding a new member to a stack, make sure that only the stack cables,
and no network cables, are connected before powering up the new unit. Stack
port configuration is stored on the member units. If stacking over Ethernet
ports, configure the ports on the unit to be added to the stack as stacking
ports and power the unit off prior to connecting the stacking cables. Make
sure the links are not already connected to any ports of that unit. This is
important because if STP is enabled and any links are UP, the STP re-
convergence will take place as soon as the link is detected.
