Important Power Considerations for Enova DGX 3200 Endpoint Systems
NOTE: This section 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 4K Input and
Output boards.
In an endpoint system, the Enova DGX Switcher has DXLink Transmitters and/or Receivers attached. The Transmitters and
Receivers can be powered either locally, remotely, or via the switcher (the last two ways are considered DXLink power since power
is received via the DXLink line).
Local power – Local power on a DXLink Transmitter or Receiver always takes precedence over power via the DXLink line
from the switcher. However, if a locally powered Module is connected to a switcher and the local power is lost
(i.e., unplugged or turned off), the Module will power down and then automatically power back up using power from the
switcher via the DXLink connection (increasing the overall power draw on the switcher). When local power is restored, it
automatically replaces the power over the DXLink line.
DXLink power – When DXLink Transmitters or Receivers are being powered by an Enova DGX DXLink board or DXLink power
injector* (using power via the DXLink line), to maintain the switcher’s power redundancy, we recommend that you:
Determine the power budget based on the input/output boards used and the quantity of powered endpoints (DXLink
Modules and Wallplates); see the following page.
Do not use the local DC power jack on the Module (even if the local power adapter is off).
* AMX supports the use of DXLink power injector PDXL-2 (FG1090-170) and PS-POE-AT-TC (FG423-84); other power injectors may
potentially damage the DXLink equipment.
IMPORTANT: If local power is used for the DXLink Modules, it must come from the provided desktop power supplies, which must not
be altered in any way.
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
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, DXLink Receiver Modules 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:
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 4K 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).
System Condition Result/Required Action
Enova DGX 3200
Within power budget The system continues 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.)
