Chapter 3: Installation
NOTE: Do not place anything below or on top of the chassis; it must have proper ventilation for cooling.
2. Connect the WRT4000 Series Router chassis’s ports to their network devices. For example, connect the LAN ports, WAN port,
USB port, and expansion ports (serial port, etc.) to the network devices, as follows:
a. Use an Ethernet 10BASE-T cable to connect the WAN port to the WAN equipment.
b. Use an Ethernet 10BASE-T cable to connect each LAN port to its equipment.
c. Connect additional network equipment to the remaining ports on the WRT4000 Series Router chassis. This includes any port in
the expansion slot.
3. Use an Ethernet cable to connect your management console (for example, a PC) to a LAN port (eth 1) on the back of the
WRT4000 Series Router.
4. If the WRT4000 Series Router chassis will use only AC input power, go to step 10.
5. If the WRT4000 Series Router chassis will use DC input power, follow step 6 through step 9 to prepare the chassis for its DC
power connection.
NOTE: The DC power source must supply 24 VDC.
6. Make sure the WRT4000 Series Router chassis is disconnected from all power sources.
7. Do the following:
a. Turn the DC power connector (the DC power plug) on its side, with the screwheads at the left and with the prongs pointing
away from you (as shown in Figure 3-33).
Figure 3-33. DC Power Connector, on Side.
b. Note the following:
• The top post is + (for the positive wire).
• The bottom post is − (for the negative/return wire).
c. Connect a minimum 14 AWG two-wire input cable to the green two-pin power connector (that is, the power plug). Make sure
you connect the correct wire to each positive or negative post. Figure 3-34 shows the plug with the cables attached.
Figure 3-34. DC Power Connector with Wires.
8. A shell cover is provided with the DC power connector, to provide strain relief for the wires. Restrain the wires against the
lower half of the shell, and place the shell around the connector, as described in the following substeps:
a. Seat the DC power connector (the plug) into the bottom half of the shell. The connector will seat into the shell in only one
way, as shown in Figure 3-35.
