Connecting Stacking Cables

Figure 3‐5 shows an example of a four‐high stack connected in a closed loop configuration. All STACK DOWN and STACK UP connectors are used in the installation. The stacking cable connections are from the STACK DOWN connector of one switch to the STACK UP connector of the next switch up in the stack. A stacking cable connection from the STACK DOWN connector of the switch at the top of the stack to the STACK UP connector at the bottom of the stack closes the loop. In a daisy chain configuration, one cable connection is not made.
