Connecting Hubs to the Stack’s Backplane
The hub ships with a stack cable.
Figure 2-2 shows how the stack cables are cascaded between the hubs
in a stack (rack). To connect up to six hubs to the backplane, plug one end
of the stack cable in the "Out" port of the top hub and the other end to the
"In" port of the next hub. Repeat this step for each hub in the stack (or
rack). Form a simple chain starting at the Out port on the first hub and
ending at the In port on the last hub.
Figure 2-2. Connecting Hubs to the Stack’s Backplane
The hubs support a power-off bypass feature which
allows traffic to pass freely across the stack’s back-
plane, even if one or more of the hubs are powered
off.
