Desktop Installation
To install and configure up to three Ethernet hubs on a desktop, use
the following steps:
1. Remove the backing from the four adhesive rubber pads and
apply the pads to the underside of each hub. Ensure that the pads
are aligned with the scribed circles at each corner.
2. Position the first hub on a table or desktop as directed by the
customer.
3. Stack the remaining hubs on top of the first hub. Ensure that the
adhesive rubber pads on the underside of a hub align with the
recesses on the top of the hub below.
4. Daisy-chain (connect) the hubs using the following steps:
a. Connect the top and middle stacked hubs, 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. Connect the bottom and middle stacked hubs, 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. Use a pointed instrument to set the medium-dependent
interface (MDI) switch on the top and middle hubs to MDI
(in) as shown in Figure 2-1 (1 and 2).
d. Set the medium-dependant interface (MDI) switch on the
bottom hub to MDIX (out) as shown in Figure 2-1 (3).
NOTE: To connect two hubs, use step b and step c (middle and
bottom hub instructions only).
