Scenario 1: Stack two switches using the internal stacking link in the same fabric
For instance, CB1 and CB2 are to be stacked. If you want the CB1 be the stack master, you need to
plug-in the CB1 first, after 20 more seconds, you plug-in the CB2.
Scenario 2: Stack two switches using the external stacking link in the different fabric
For instance, CB1 and CB3 are to be stacked. If you want the CB1 to be the stack master, you need to
plug-in the CB1 first, after 20 more seconds, plug-in CB3 and connect the external stacking cable
between CB1 and CB3 within next 20 seconds.
Scenario 3: Stack four switches using both internal and external stacking link
For instance, CB1, CB2, CB3, and CB4 are to be stacked. First, you need to plug-in the SWM that you
prefer to be the stack master (CB1) to the fabric, and then plug-in CB2 20 seconds later (refer to
scenario 1). Then, you plug-in CB3 and connect the external stacking cable between CB1 and CB3
within the next 20 seconds. Plug-in CB4 and finally connect the external stacking cable between CB2
and CB4.
For the first time installation, the powering consideration has to be followed, otherwise it is
!
not determined which CB will be the master (see master election process). If you have been
saved the configurations, you could power them on together. However, the external
stacking cables have to be present all the time during powering on.
