16 Installation ELH100-12/24TXConnecting Hubs to the Stack’s BackplaneThe hub ships with a stack cable.Figure 2-2 shows how the stack cables are cascaded between the hubsin a stack (rack). To connect up to six hubs to the backplane, plug one endof 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 (orrack). Form a simple chain starting at the Out port on the first hub andending at the In port on the last hub.Figure 2-2. Connecting Hubs to the Stack’s BackplaneThe hubs support a power-off bypass feature whichallows traffic to pass freely across the stack’s back-plane, even if one or more of the hubs are poweredoff.
