Power Budget Planning for Enova DGX 3200 with DXLink Boards

Before installing an Enova DGX 3200 Switcher and connecting any required DXLink Transmitters and Receivers, the power draw for
the system should be calculated in order to maintain the power redundancy of the power supplies in the enclosure. (Each Enova
DGX 3200 enclosure ships with two mutually-redundant power supplies.)
IMPORTANT: If you do not want to draw power from the Enova DGX 3200 enclosure's power supplies, you must power the DXLink
Transmitter and Receiver Modules with local power (must use the provided desktop power supply) or remote power (must be a DXLink
power injector). Local or remote power always overrides power from the switcher. If local or remote power is turned off, the DXLink
Transmitters and Receivers do not power down but immediately start drawing power from the switcher.
Power Budget Calculation
Calculating the power budget helps determine how many DXLink Transmitters and Receivers can be powered via the Enova DGX
3200 Switcher while maintaining power redundancy if one of the power supplies should fail. The Enova DGX Configuration Tool is
used to determine the switcher's power budget. Simply enter the types of boards and the number of DXLink Transmitters and
Receivers to be powered via the switcher, and the calculator shows the resulting power draw. The Enova DGX Configuration Tool is
located at www.amx.com/enova. If more DXLink units are required than the switcher can support while maintaining redundancy,
they must be powered using the provided desktop power supplies (which must not be altered in any way) or a DXLink power
injector; otherwise, damage may occur.
Foregoing Power Supply Redundancy
Depending on particular Enova DGX 3200 Switcher input and output board configurations, operating over the redundant power
supply level may be necessary on a permanent basis for some installations. While foregoing the benefits associated with a
redundant power supply should be understood, operating without redundancy is in no way detrimental to the system, as long as
both power supplies are operational. In this case, necessary power will be pulled evenly from both supplies. However, the loss of
one power supply will result in the system being non-operational from a normal "non-redundant" system capability perspective.
In the Event of a Power Supply Failure
If an Enova DGX 3200 power supply fails, check the table below to determine which situation applies and any actions that may be
required:
System
Enova DGX 3200
NOTE: The table above does not apply to the Enova DGX 800/1600/6400 because the system is capable of providing power for the
maximum number of DXLink Transmitters and Receivers required when the enclosure contains all DXLink Twisted Pair Input and
Output boards.
In both the situations in the table above, the power supply should be replaced as soon as possible to restore power redundancy to
the system or to allow the system to become fully operational again. Unless the Enova DGX 3200 has exceeded its power budget, it
should operate normally with a failed power supply. For power supply replacement information, contact technical support (see
page 61).
Connecting Switching Systems with DXLink Connectors
Switching systems with DXLink Twisted Pair support (e.g., an Enova DGX Switcher and an Enova DVX-3150HD) can be connected via
their DXLink (RJ-45) ports.
IMPORTANT: This section does not refer to the linking of enclosures from CPU to CPU, which is not supported in the Enova DGX
Switcher.
In an installation with a multiple-stage switching system, the following applies:
When two switching systems with DXLink support are connected via their DXLink ports, only video and audio will be passed

through the DXLink connection.
When a DXLink input or output on one switching system determines that it is connected to a DXLink input or output on

another switching system, the DXLink port will automatically disable all Ethernet, power, and control on that connection
port so that the only things passed down the DXLink line are the video and audio signals.
When connecting switching systems via DXLink ports, AMX recommends no more than 3 switcher throughputs.*

Network loops must be avoided (see the following page).

* For example, the path through 3 switchers could be: source device > Enova DVX-3250HD (out a DXLink/HDMI port) > Enova DGX
3200, DXLink input (out a DXLink port) > Enova DGX 1600, DXLink input (out a DXLink port) > DXLink Receiver > display device as
an HDMI signal.

Condition
Within power budget The system will continue to run; okay to leave it powered until the failed power
supply is replaced.
Over power budget The remaining power supply will turn off. If enough DXLink Transmitter or Receiver
Modules are removed (or otherwise powered) to bring the system's power budget
within its maximum limit, the system will be able to run until the failed power
supply is replaced. (You can also remove some input and/or output boards.)
