Epica DGX 16 and Epica DGX 32 Instruction Manual
Input and Output Signal Cables
When attaching input and output signal cables in a multiple-enclosure system, check the system and
enclosure numbers are on the rear of the Epica DGX 16 or 32 (if not on the rear, the numbers are on the
side). The system was programmed at the factory to operate only as a specifically configured system.
If AMX AutoPatch cable management bars are used, they are installed before attaching cables
(see page 23).
Before connecting all input and output cables, attach only the first two input and output cables (and any
applicable DGX Fiber modules) and execute a test switch (see page 40). When the test switch is
successful, attach the rest of the input and output cables.
For information on cabling specific types of connectors, see the DGX SC Optical Board chapter on
page 47 or the DGX DVI Board chapter on page 53.
Applying Power and Startup
The enclosures’s universal power receptacles will accept all major international standard power sources.
(Two US power cords are included with all shipments unless ordered otherwise.) Maximum power
specifications are on each power receptacle (also listed on page 14). Always use earth-grounded power
cords / system with an Epica DGX 16 or 32.
The source electrical outlet 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.
To avoid an overload, note the power consumption rating of all the equipment connected to the circuit
breaker before applying power.
Complete Power Redundancy Setup
For proper redundant operations, both power supplies must be powered at all times. To take full
advantage of dual power feeds and redundant power supplies on the Epica DGX 16 and 32, we
recommend cabling the primary Epica DGX 16 or 32 power feed, via a power strip to an outlet
connected to one circuit breaker and the redundant power feed via a power strip to an outlet connected to
a second circuit breaker (FIG. 22). For linked systems with redundant power supplies, repeat pattern.
Caution: We recommend attaching all power cords to a surge protector and/or an AC line
conditioner.
