Safety Recommendations For Laser Products; Adding Or Replacing A Board - AMX Enova DGX 8 Instruction Manual

Safety Recommendations for Laser Products

Warning: DXLink Fiber uses a Class 1 laser product to send signals. While the Class 1 category indicates
that the invisible laser used is safe, we recommend avoiding direct eye exposure when using any optical
fiber product.
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 DGX SC Optical Boards.
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 Epica SC Fiber and DXLink Fiber products to avoid direct eye exposure to invisible
laser radiation. Follow the recommendations below whenever installing or working with these 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 and DXLink Fiber connectors or the dust caps from the fiber cables
 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
 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 222.
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.
Important: The Audio Insert/Extract board is not hot-swappable; when installing an AIE Board, be sure to
power down the system.
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 172).
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.
