Safety Recommendations for Laser Products
Important: No user serviceable parts are included inside an AMX AutoPatch product; service should
only be done by qualified personnel.
Caution: Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
Exercise caution when installing DGX SC Optical Boards to avoid direct eye exposure to invisible laser
radiation. Follow the recommendations below whenever installing or working with DGX 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.
Replacing or Adding 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, Epica DGX 16 and 32 systems 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 149.
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 Epica DGX 16 or 32 Board:
1.
Optional for systems with SC Optical boards – Power down the enclosure (see the “Caution” at the
bottom of page 145).
2. Epica DGX 32 only – Loosen the two captive screws (one on each end) that hold the connector
numbering plate at the top of the boards, and set the plate aside.
3. If applicable – Label and disconnect all cables on the board being replaced. If cables from adjoining
boards obstruct access, label and disconnect them as necessary.
If the system is not powered down:
 For disconnecting a DGX SC Optical input board – Before disconnecting the fiber cables,
disconnect the power on the DGX TX Transmitter modules that are connected to the inputs.
 For disconnecting a DGX SC Optical output board – Before disconnecting the fiber cables,
disconnect the switches for those output connectors.
