You can use any of the RJ-45 or QSFP+ ports for stacking, provided it is configured as a stacking port. CAUTION: To connect S4820T systems, use only Dell Force10 supported stacking cables. To connect two S4820T systems in a ring (Figure 4-9), starting with the S4820T at the bottom of the stack, follow these steps: NOTE: The port numbers in the following procedure are examples only. Step Task 1 Insert one end of the first cable into stack port 60 in chassis 1 (bottom). 2 Insert the other end of the same cable into stack port 52 on chassis 2 (top). 3 Insert a second cable into stack port 56 on chassis 2 (top). 4 Insert the other end of the second cable into stack port 56 on chassis 1 (bottom). 34 | Installing the S4820T
