4. To interconnect three hubs:

NOTE: To connect two hubs, use step a and step c (top and middle

hub instructions only).

a. To connect the top and middle hubs in the stack, connect an

RJ-45 patch cable to port 24 of the top hub, then connect the

cable to port 12 of the middle hub.

b. To connect the bottom and middle hubs in the stack, connect a

second RJ-45 patch cable to port 24 of the middle hub, then

connect the cable to port 12 of the bottom hub.

c. Using a pencil or other pointed instrument, set the medium-

dependent interface (MDI) switch on the top and middle hubs

to MDI (in). Set the MDI switch on the bottom hub to MDIX

(out). The configuration is shown in Figure 2-2 on page 2-10.
