Wall-Mounting Instructions –MTA8328-4, MTA8328-8
Optionally, you may choose to mount your MTA on the wall.
1. Use the provided template to drill two holes on the wall.
2. Use a screwdriver to install one #6 metal screw in each hole. Leave the screw
heads 1/4 to 3/8 inch away from the wall.
3. Position the MTA with the ports at the top.
4. Place the unit above the screws and lower it so the screw heads are inside and
at the tops of the wall mount slots on the back of the unit.
5. Adjust to ft. If the unit is too loose, remove it from the wall, slightly tighten
screws, and rehang.

Important Safety Instructions
This section contains important safety information you should know before
working with the DEVICE. Use the following guidelines to ensure your own personal
safety and to help protect your DEVICE from potential damage.
This warning symbol means danger. You are in a situation that could
cause bodily injury. Before you work on any equipment, be aware of the hazards
involved with electrical circuitry and be familiar with standard practices for
preventing accidents
Only trained and qualified personnel should be allowed to install, replace, or
service this equipment.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and
WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45
connectors. Use caution when connecting cables. Statement 1021
Before working on a system that has an on/off switch, turn OFF the power
and unplug the power cord.
This unit is intended for installation in restricted access areas. A restricted
access area is where access can only be gained by service personnel through the
use of a special tool, lock and key, or other means of security, and is controlled by
the authority responsible for the location.
This product relies on the building’s installation for short-circuit
(overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120
VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all
current-carrying conductors).
This equipment must be grounded. Never operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is
available.
Do not work on the system or connect or disconnect cables during periods
of lightning activity.
Before working on equipment that is connected to power lines, remove
jewelry (including rings, necklaces, and watches). Metal objects will heat up when
connected to power and ground and can cause serious burns or weld the metal
object to the terminals.
The safety cover is an integral part of the product. Do not operate the unit
without the safety cover installed. Operating the unit without the cover in place
will invalidate the safety approvals and pose a risk of fire and electrical hazards.
Enclosure covers serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic
interference (EMI) that might disrupt other equipment; and they direct the flow of
cooling air through the chassis. Do not operate the system unless all covers are in
place.
Ultimate disposal of this product should be handled according to all national
laws and regulations.
To prevent bodily injury when mounting or servicing this unit in a rack, you
must take special precautions to ensure that the system remains stable. The
following guidelines are provided to ensure your safety:
 This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
 When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
 If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
