Connecting Switching Systems with DXLink Fiber Connectors
Enova DGX switching systems with DXLink Fiber support can be connected via their DXLink Fiber 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 Fiber support are connected via their DXLink Fiber ports, only video and audio will
be passed through the DXLink Fiber connection.
When a DXLink Fiber input or output on one switching system determines that it is connected to a DXLink Fiber input or
output on another switching system, the DXLink Fiber port will automatically disable all Ethernet and control on that
connection port so that the only things passed down the DXLink Fiber line are the video and audio signals.
Compatibility between boards types from switcher to switcher must be maintained: multimode to multimode and single
mode to single mode.
When connecting switching systems via DXLink Fiber ports, AMX recommends no more than 3 switcher throughputs.*
Network loops must be avoided (see below).
* For example, the path through 3 switchers could be: source device > Enova DGX 800 (out a DXLink Fiber port) > Enova DGX
3200, DXLink Fiber input (out a DXLink Fiber port) > Enova DGX 1600, DXLink Fiber input (out a DXLink Fiber port) > DXLink Fiber
Receiver > display device as an HDMI signal.
Avoiding Network (Ethernet) Loops
CAUTION: Be careful not to create a network (Ethernet) loop.
Only one connection to the Public LAN is permitted within a switching system with DXLink Fiber support.** Network loops must be
avoided. A network loop is created when the enclosure and one or more DXLink Fiber, Duplex units in Bidirectional Mode within the
system are connected to the same Public LAN as the Enova DGX. The Enova DGX Switcher does not support STP (Spanning Tree
Protocol).
** This applies to systems with DXLink Fiber Boards, Duplex in Bidirectional Mode and/or DXLink Twisted Pair Boards and DXLink
Twisted Pair 4K Boards.
Example
In the example in FIG. 60, a network loop was created when an Enova DGX 1600 was connected to a Public LAN and one of its
DXLink Fiber, Duplex Transmitters in Bidirectional Mode was connected to the same Public LAN as the Enova DGX. The DXLink Fiber,
Duplex Transmitter needs to be disconnected from the LAN. The same problem would also occur if an enclosure and one (or more)
of its DXLink Fiber, Duplex Receivers were connected to a common Public LAN.
IMPORTANT: For Duplex hardware in Bidirectional Mode connected to an Enova Digital Media Switcher, we recommend connecting
the switcher to the network for all network connection needs. Network connections via the switcher are faster and more reliable.
Never connect both a TX and RX, a TX and switcher, or a switcher and RX to the same network: Avoid network loops.

Avoid network loops
IMPORTANT: If you have questions or
concerns about network setup, consult
with your network administrator about
avoiding network loops before connecting
units.
