4.4.2 Stacking Unmanaged SEH Hubs Together
Use the following procedure to stack non-intelligent hubs (SEHs)
together.
1. Power up each SEH in the stack by plugging the power cord into the
back panel of the SEH and plugging the other end into a grounded
receptacle.
2. Verify that the PWR LED for each hub is on, indicating that each SEH
is receiving power.
3. Attach the interconnect cable to the “IN” port on the rear panel of the
second SEH in the stack as shown in Figure 4-5.
4. Attach the other end of the interconnect cable to the “OUT” port on the
rear panel of the first SEH in the stack.
5. Continue connecting ports in this manner until all hubs are connected.
