Instruction Manual – Enova DGX 8/16/32 Digital Media Switchers
Safety Recommendations for Laser Products
Caution: The safety recommendations for laser products include applying power last. If instead
of powering down during the board replacement procedure, you decide to take advantage of the
DGX SC Optical Board’s ability to hot-swap, be sure
that you follow the rest of the laser safety
recommendations here and in the instructions when replacing a DGX SC Optical Board.
Caution: Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
Important: No user serviceable parts are included inside Enova DGX enclosures; service should only
be done by qualified personnel.
Exercise caution when installing DGX Fiber products to avoid direct eye exposure to invisible laser
radiation. Follow the recommendations below whenever installing or working with DGX Fiber products.
 Be sure to apply the power only after all fiber connections are made and no fiber ends are
exposed.
 Do not remove dust plugs from SC fiber connectors or the dust caps from the fiber cables until
establishing connections; avoid direct eye exposure.
 Make sure all cables, including fiber cables, are correctly connected and/or terminated.
 Before you unplug a fiber cable on an input board, disconnect the power on the DGX TX that
is connected to the input.
 Before you unplug a fiber cable on an output board, disconnect the switch for that output
connector.
Adding or Replacing a Board
Important: When replacing a board, be sure to install the new board in the same slot that held the
original board to make sure the switching commands are correct.
In almost all cases, Enova DGX Switchers are configured to accommodate a full enclosure’s worth of
boards and do not require modification to the configuration file when a board is added. If you cannot
execute switches with the new board after it has been installed, the configuration file may need to be
updated; see “Board Troubleshooting” on page 210.
Caution: Cable management bars are not to be used as handles to remove or install boards.
In the following procedure, read each step entirely. The steps include helpful tips to avoid damage to the
enclosure’s internal cables and connectors.
To remove and replace an Enova DGX board:
1.
Optional – If the board being replaced has custom settings that have not been saved, use DGX
Configuration Software to save the settings now (see page 157).
2. Optional – For SC Optical Boards, we recommend unplugging the AC power cords from both of the
power supplies (be sure to read the first
Caution at the top of this page.)
3. Enova DGX 32 only – Loosen the captive screw on each end of the connector numbering plate
above the boards, and set the plate aside.
