1. READ these instructions.
2. KEEP these instructions.
3. HEED all warnings.
4. FOLLOW all instructions.
5. DO NOT use this apparatus near water.
6. CLEAN ONLY with dry cloth.
7. DO NOT block any ventilation openings. Install in accordance with the manufacturer's instructions.
8. DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that
produce heat.
9. DO NOT defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding prong. The wider blade or the third prong are provided for your
safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. PROTECT the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
11. ONLY USE attachments/accessories specified by the manufacturer.
12. USE ONLY with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is
used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. UNPLUG this apparatus during lightning storms or when unused for long periods of time.
14. REFER all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as
power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped.
15. DO NOT expose this apparatus to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on
the apparatus.
16. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug from the AC receptacle.
17. Where the mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
18. DO NOT overload wall outlets or extension cords beyond their rated capacity as this can cause electric shock or fire.
The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the product.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons.
ESD Warning: The icon to the left indicates text regarding potential danger associated with the discharge of static electricity from an outside
source (such as human hands) into an integrated circuit, often resulting in damage to the circuit.
WARNING: To reduce the risk of fire or electrical shock, do not expose this apparatus to rain or moisture.
WARNING: No naked flame sources - such as lighted candles - should be placed on the product.
WARNING: Equipment shall be connected to a MAINS socket outlet with a protective earthing connection.
WARNING: The bottom of the enclosure is a hot surface. Do not touch!

Instruction Manual - NXA-ENET8-POE+
ESD WARNING
WARNING: This product is intended to be operated ONLY from the voltages listed on the back panel or the recommended, or
included, power supply of the product. Operation from other voltages other than those indicated may cause irreversible
damage to the product and void the products warranty. The use of AC Plug Adapters is cautioned because it can allow the
product to be plugged into voltages in which the product was not designed to operate. If the product is equipped with a
detachable power cord, use only the type provided with your product or by your local distributor and/or retailer. If you are
unsure of the correct operational voltage, please contact your local distributor and/or retailer.
RACK MOUNTING
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given
to supply connections other than direct connections to the branch circuit (e.g. use of power strips)."
FCC AND CANADA EMC COMPLIANCE INFORMATION:
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if it is not
installed and used in accordance with the instruction manual, it may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required
to correct the interference at his own expense.
CAN ICES-3 (A)/NMB-3(A)
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before
touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be
followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive
smocks, and conductive work mats are specifically designed for this purpose. These items should not be manufactured
locally, since they are generally composed of highly resistive conductive materials to safely drain static discharges, without
increasing an electrocution risk in the event of an accident.
Anyone performing field maintenance on AMX equipment should use an appropriate ESD field service kit complete with at
least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with ano ther ground cord.
WARNING: Do Not Open! Risk of Electrical Shock. Voltages in this equipment are
hazardous to life. No user-serviceable parts inside. Refer all servicing to qualified
service personnel.
Place the equipment near a main power supply outlet and make sure that you can
easily access the power breaker switch.
Avoid exposure to extreme heat and cold.
