DC900X INSTALLER’S MANUAL (501-3434310) RELEASE 30th Oct. 2009
CONNECTING THE EQUIPMENT (cont.)
Using existing cabling
In the diagram of a typical home network shown on page 10:
• Existing coaxial cables, which run around the home behind walls, above ceilings etc, are shown in red.
• The cable from the point of entry (POE) to the house is split using a coaxial splitter, which is typically in
the attic, but could be elsewhere in the home. This splitter should be rated up to 1.5 GHz.
• Existing “visible” coaxial cables in each room, which were used to connect set-top to the coaxial wall
output in each room, are shown in blue.
You can use all of these existing cables, but ensure, wherever possible, that they are not damaged. We also
recommend that you use crimped (not screw-on) F-type connectors.
Remember to disconnect the existing set-tops from the power supply before disconnecting/connecting any
other cables to their rear panels. See page 12 for details on powering up all the equipment after installation.
Deciding on the location for the NAS
Choose a position for the NAS near one of the existing set-tops. This set-top will become “Client set-top 3”
in the MoCA-Ethernet hybrid network. Typically you would place the NAS below the set-top, allowing three
inches of ventilation space between them.
Connecting an additional coax splitter
Both the NAS and client set-top 3 need to be connected to the coaxial cable network in the home. If there is
only one coaxial wall output in the room where they are both located, you must connect a coaxial splitter (rated
up to 1.5 GHz) at the coaxial wall output in that room, as shown in the diagram on page 10.
Connecting up the NAS
Connect a new coaxial cable between the NAS’s CABLE IN connector and the coaxial wall output (or the
additional coax splitter, if you have had to install one – see above).
Connect an Ethernet (Cat5e/Cat6) cable between the Ethernet connectors on the NAS and client set-top 3.
Connect the 12 V power supply unit to the DC IN connector on the NAS, but do not yet apply power to the NAS
(you must do this after the whole network is connected up).
Connecting a low-pass filter at client set-top 3
Disconnect the existing coaxial cable from the CABLE IN connector on client set-top 3.
Connect a low-pass filter at the CABLE IN connector on client set-top 3.
Connect the existing coaxial cable to the low-pass filter.
Connecting a low-pass filter at the POE
Connect one low-pass filter into the main coaxial cable at the POE to the home.
If it is not convenient to connect it at the POE, you could connect it at another convenient point in this main
coaxial cable that runs between the POE and the first coaxial splitter in its path. This could even be at the input
to the coaxial splitter in the attic.
Connecting up client set-tops 1 and 2
Disconnect the existing coaxial cable from the CABLE IN connector on client set-top 1.
Connect this existing cable to one of the coax connectors on a MoCA dongle (Ethernet-Coax Bridge).
Connect a new coaxial cable between the second coax connector on the MoCA dongle and the CABLE IN
connector on client set-top 1.
Connect an Ethernet (Cat5e/Cat6) cable between the Ethernet connectors on the MoCA dongle and client set-top 1.
If the MoCA dongle has a MoCA/CONFIG switch, set it to the MoCA position.
Do not yet apply power to the MoCA dongle (you must do this after the whole network is connected up).
Repeat the above steps for client set-top 2.

NOTE
The numbers for the client set-
tops (1, 2 and 3), as seen on the
Diagnostics screens (see page 16)
are assigned by the network when
it is up and running. They may not
correspond to the numbers in these
connection diagrams. You can
use the eSTB MAC addresses on
the base of the clients to cross-
reference the actual clients with the
on-screen client names/numbers.
