3.If you are installing this switch in a stacked configuration, repeat this procedure for each switch until all switches have been installed in the stack, then proceed to “Connecting Stacking Cables” on page 3‐11. Otherwise, proceed to “Connecting AC and RPS‐SYS Power” on page 3‐16.

Connecting Stacking Cables

The stack of switches can be connected in a closed loop or daisy chained. In a closed loop all the switches are connected in sequence and the last switch in the stack is connected back to the first switch. In a daisy chain configuration the cable that would return the connection back to the first switch in a closed loop is not installed. The advantage of the closed loop is redundancy, this configuration eliminates any single point of failure. Up to eight switches can be stacked together and connected by standard UTP Category 5 or better cables. The stacking cables allow the entire stack to operate with a single IP address.
