Enova Digital Media Switchers - Hardware Reference Manual
Expansion Boards
IMPORTANT:
Audio Switching Boards, Dante Audio Switching Boards, and Audio Insert/Extract Boards are not compatible.
Do not install mixed types of expansion boards in the same enclosure. If two types of boards are present, the audio
subsystem is disabled.
IMPORTANT:
If you plan to use the instructions in this appendix, remember that Enova DGX expansion boards must be
installed in expansion board slots. Although Audio Switching Boards are hot-swappable, Audio Insert/Extract Boards are
not hot-swappable; be sure to power down the system.
Procedure Overview
IMPORTANT:
Adding or replacing boards should only be done by personnel trained to handle ESD sensitive parts and
assemblies.
ESD WARNING: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded
before touching any internal Enova DGX materials. Use an ESD wristband and cord with an alligator clip attached to a good
ground source.
Items Required
Enova DGX board(s)
Phillips #1 screwdriver
ESD wristband and cord with alligator clip
PC with NetLinx Studio (or another terminal emulation program) and a null modem serial cable (RS-232)
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 (see the OSHA directive on
page 146).
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 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 DXLink 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 Transmitter that is connected to
the input.
Before you unplug a fiber cable on an output board, disconnect the switch for that output connector.
