Figure 2-2 Mounting Bracket Installation (Ethernet Hub)
2. Position the hub as directed by the customer. Align screw holes in
the mounting brackets with screw holes in the rack-mount
standards.
3. Secure both sides of the hub to the rack-mount standards. Use the
1/8-inch Allen wrench and four Allen-head mounting screws
(10/32 x 0.5-inch) provided.
4. Repeat step 1 through step 3 for the remaining hubs.
5. Daisy-chain (connect) the hubs using the following procedure:
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 Figure 2-1 (1 and 2), to set the
medium-dependent interface (MDI) switch on the top and
middle hubs to MDI (in). As shown in Figure 2-1 (3), set the
MDI switch on the bottom hub to MDIX (out).
NOTE: To connect two hubs follow the middle and bottom hub
instructions only.
6. Connect a power cord to a rack power strip and the receptacle at
the rear of each hub. Power for each hub switches on when the
hub (and equipment rack) are connected to facility AC power.
