Instruction 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 situation 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.
For additional information on power supplies and power supply troubleshooting for an Enova DGX Switcher, see the

information, contact technical support (see page 102).
System
Condition
Result / Required Action
Enova DGX 8/16
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
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.)
