Enova Digital Media Switchers - Hardware Reference Manual
Applying Power and Startup
Overview
The enclosure’s universal power receptacles will accept all major international standard power sources. Two US power
cords are included with all enclosures shipped within the US. Maximum power specifications are on each power
receptacle (and are also listed on page 20). Always use earth-grounded power cords and equipment with an Enova DGX
Switcher.
The source electrical outlet(s) should be installed near the enclosure, easily accessible, and properly grounded. Power
should come from a building branch circuit. We strongly recommend using a dedicated line for the system’s power. Use a
minimum breaker current rating of 20 A for 110 V or 10 A for 230 V for each circuit. To avoid an overload, note the power
consumption rating of all the equipment connected to the circuit breaker before applying power.
Power Budget Planning for Systems with DXLink Twisted Pair Boards
If an Enova DGX 3200 system contains DXLink Twisted Pair Boards, be sure to read the section on "Power Budget Planning"
in board chapter. The power draw for the system should be calculated in order to maintain the power redundancy of the
power supplies in the enclosure. Calculating the power draw also helps determine how many DXLink Transmitters and
Receivers can be powered via the switcher.
Complete Power Redundancy Setup
IMPORTANT:
For proper redundant operations, all power supplies must be powered at all times.
Enova DGX 800/1600/3200 –
To take full advantage of the multiple power feeds and redundant power supplies, cable the
primary power feed to an outlet connected to one circuit breaker. The redundant power feed should be cabled to an
outlet connected to a second circuit breaker (FIG. 31).
Enova DGX 6400 –
To provide adequate power for an N+1 redundant application, connect each of the power supplies to
its own circuit.
CAUTION:
Attach all power cords to a surge protector and/or an AC line conditioner.
Power-Up Sequence
NOTE:
Enova DGX 6400 only - Four AC power filtering Ferrites (one per cord) are provided to ensure the system meets or
exceeds the radiated emission requirements defined in standards EN55022:2010, FCC 15.109(g):2014, and ICES-003:2012.
To install these filters, clamp in place onto the power cords as close to the power supply as reasonably possible for the
system.
IMPORTANT:
Enova DGX 6400 only – If two or more power supplies are not receiving power, shut down power to all power
supplies then restart the system with all power supplies connected.
The following instructions start with attaching only two source and destination devices for the purpose of executing a test
switch (after the factory default switch is disconnected).
