Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
Power Budget Calculation
Calculating the power budget helps determine how many DXLink Transmitters and Receivers can be powered through the Enova
DGX Digital Media 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 through the switcher, and the calculator shows the resulting power draw.
The
Enova
DGX Configuration Tool
is at www.amx.com/enova.
If more DXLink units are required than the switcher can support while maintaining
redundancy, any DXLink Modules can be powered using the provided desktop
power supplies or DXLink Power Injectors: PDXL-2 (FG1090-170) or
PS-POE-AT-TC (FG423-84).
Wallplate and Decor Wallplate Transmitters
must
be included in the power
calculations unless they are being powered by a DXLink power injector (
must
be
AMX approved).
IMPORTANT:
AMX does not support the use of any power supplies other than the
provided ones or power injectors other than the ones approved as they may
potentially damage the DXLink equipment.
Foregoing Power Supply Redundancy
Depending on particular Enova DGX 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 power supply fails, check the table below to determine which condition* applies and any actions that may be
required:
In all of the situations 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 Digital Media Switcher has exceeded its power
budget, it should operate normally with a failed power supply.
* The over power budget condition does not apply to Enova DGX 64/6400 Switchers (which have four power supplies).

System
Condition
Result/Required Action
Enova DGX 8/16 and 800/1600
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 system will continue to run; however, we do not recommend leaving
it powered until the failed power supply is replaced, unless enough
DXLink Transmitter or Receiver Modules are removed (or otherwise
powered) to bring the system’s power budget within its maximum limit.
(Another option is to remove some of the input and/or output boards.)
Enova DGX 32 and 3200
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.)
