 FastHub Stacks C-7
Numbering Convention of Hubs in a Stack
Numbering Convention of Hubs in a Stack
The physical position of the hubs in the hub stack and the stacking cable connections
between hubs determine how they appear to the management interface. The FastHub
management interface uses a hub-numbering convention, assigning numbers from top to
bottom—the hub at the top of the stack is Group 1, the hub below Group 1 is Group 2, and
so on (see Figure C-3). If you have four hubs in a stack and you remove Group 3 and
connect the stacking cable from Group 2 to Group 4, Group 4 is renumbered as Group 3.
If a hub stack has more than one management hub, the upper management hub in the stack
is the primary management hub. The lower management hub is the secondary management
hub. For more information, see the “Managing a Hub Stack” section on page C-6.
