Assembling the
components, modem
installation method
Follow the steps below and refer to the illustrations on page 13
through page 16 to assemble the DW4020 components. Note that
some cables are connected to the installer laptop until
commissioning is complete. Then the DW4020 is connected to
the customer’s computer.
Before beginning the installation, be sure that you have installed
the installation software correctly. See Installing the software on
page 9. In addition, confirm that DHCP is enabled to accept IP
addresses automatically on your installer laptop PC. See
Appendix D – on page 113.
1. Be sure the power supply is not plugged into a wall outlet,
surge protector, or power strip.
2. Lay two of the four clips on a table and mount the
components as shown in Figure 8. Mount the Gateway first,
then the transmit modem, then the receive modem.
3. Turn the component stack right side up and install the other
two clips as shown in Figure 9.
4. Double-check that the components are installed in this order
from top to bottom: receive modem, transmit modem,
Gateway. See Figure 10.
CAUTION
• The components must be stacked in this order: Gateway
on bottom; transmit modem on top of Gateway; receive
modem on top of transmit modem. See Figure 10.
• If the components are not stacked in the proper order, the
receive modem may overheat and malfunction.
• Do not block any ventilation openings. Do not install near
any heat sources such as radiators, heat registers,
ovens, stoves, or other apparatus (including amplifiers)
that produce heat.
• Recommended ventilation space around the top and
sides of the DW4020 assembly should be approximately 6
inches. Ventilation is necessary to avoid overheating.
Note: The Gateway and the transmit modem have a hole at
the center of each of their four feet. There is a tab on the
bottom of each mounting clip, which snaps into place on the
Gateway when properly aligned over the hole.There is also a
tab in the middle of each mounting clip, which snaps into place
on the transmit modem when properly aligned over the hole.
