2-2. UNPACKING
A preliminary inspection of the equipment container should be made before un-
packing. Evidence of damage should be noted and reported immediately.
To unpack, place the container on a clean flat surface, cut all straps, and open or re-
move top. Carefully take out the DV-MUX3 and all the accessories packed in the
container, and place them securely on a clean surface. Inspect the product for dam-
age. Immediately report any damage.
2-3. SITE REQUIREMENTS
Power AC-powered DV-MUX3 units should be installed within 1.5 m (5 feet) of an eas-
ily-accessible grounded AC mains outlet capable of furnishing the nominal supply
voltage of the DV-MUX3 ( in accordance with your order). The supply voltage is
marked on a label located on the rear panel, near the power connector.
DC-powered DV-MUX3 units require a -48 VDC source.
The DV-MUX3 does not include a power switch, and will start operating as soon
as its power cable is connected to power. Therefore, a circuit breaker located at a
convenient location, that will also serve as an on/off switch, must beincluded in the
circuit used to provide power to the DV-MUX3.
Cable Connections The DV-MUX3 has two 15-pin female D-type connectors (one connector for the
data channel, and the other connector for the main link) and two RJ-45 connectors
for the two voice channels. Various adapter cables are available for interface con-
version. Appendix A provides connector pin allocations, and wiring data for the
adapter cables.
Front and Rear
Panel Clearance
When the DV-MUX3 is installed in a 19" rack, allow at least 90 cm (36 inches) of
frontal clearance for operator access. Allow at least 10 cm (4 inches) clearance at
the rear of the unit for interface cable connections.
Ambient
Requirements
The ambient operating temperature of the DV-MUX3 should be 0 to 45°C (32 to
104°F), at a relative humidity of up to 90%, non-condensing.
Do not place another unit on top a DV-MUX3 unit, because this will obstruct the
free flow of cooling air around the unit,
