Wood pole mounting only: one 1/4-inch diameter, 3 1/2-inch long lag bolt
Site Planning
To ensure safe and durable wiring, router installation must follow appropriate electrical and
building codes. Follow the National Electrical Code (NEC) requirements, unless local codes in
your area take precedence over the NEC code.
The following distance limits apply to installations that have 10/100 Base-T Category 5 network
cables attached to the routers:
300 feet maximum between devices for 100BaseT operation
500 feet maximum for 10BaseT operation.
The Ethernet duplex and speed setting is configurable.
Note
National Electrical Codes (NEC) Article 800 requires the use of Agency Listed (UL/CSA/TUV) Building
Entrance Protector for all power and data communications cables entering a building. The NEC
intends by Article 800 to protect the building and occupants from fires caused by transient voltage and
current surges.
Note
Ethernet data cable installations having lengths greater than 140 feet in the outdoor environment must
use a UL497 approved (UL/CSA/TUV Listed) primary protection device at the building entrance.
Ethernet data cable installations having lengths less than 140 feet in the outdoor environment may use
a UL497A (UL/CSA/TUV Listed) secondary protection device at the building entrance. Tropos Data
Protection Device and Network Protection Units are UL497A secondary protection devices.

Preparing for Installation
Tropos MetroMesh Routers Installation Guide, Models 6310 and 6320 5
Location Guidelines
Tropos routers are radio devices and therefore susceptible to interference that can reduce
throughput and range. Follow these guidelines to ensure the best performance:
Install the unit in an area where trees, buildings, and large steel structures do not obstruct
radio signals to and from the antenna. Direct line-of-sight operation is best.
Install the unit away from microwave ovens or other devices operating in the 2.4 GHz,
4.9 GHZ, or 5.8 GHz frequency range.
Install the unit away from other possible sources of 802.11a/b/g/n interference, such as
cordless phones, home spy cameras, frequency hopping (FHSS) and DSSS LAN
transceivers (non-802.11), electronic news gathering video links, radars, amateur radios,
land mobile radio services, local government sites (such as law enforcement), fixed
microwave services, local TV transmission and private fixed point transmitters.
Site Surveys
Due to variations in component configuration, placement, and physical environment, each
installation is unique. Before installing routers, perform a site survey to determine the optimum
placement of units for maximum range, coverage, and network performance. Consider the
following factors when performing a site survey:
Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum
radio range is achieved at the lowest workable data rate. A decrease in receiver threshold
sensitivity occurs as radio data rate increases.
Antenna orientation—Proper antenna orientation is a critical factor in maximizing radio
range. As a general rule, range increases in proportion to gain and antenna height measured
from the ground.
Physical environment—Clear or open areas provide better radio range than closed or filled
areas. The less cluttered the operating environment, the greater the range.
Obstructions—A physical obstruction, such as a building or tree, can block or hinder
communication. Avoid locating antennas in a location where there is an obstruction between
sending and receiving devices.
Building materials—Radio penetration is influenced by the building material used in
construction. For example, drywall construction permits greater range than concrete blocks.

Mounting Strategies
Tropos MetroMesh Routers Installation Guide, Models 6310 and 6320 6
Power Source
The Tropos 6310 and 6320 routers are powered by power over Ethernet (PoE) input:
PoE (20-60Vdc)
100-277 VAC with external accessory
Caution
Tropos 6310 and 6320 routers use proprietary PoE. The routers are not 802.3af
compliant.
Safety
Installing the routers can pose a serious hazard. Be sure to take precautions to avoid the
following:
Exposure to high voltage lines during installation
Falls when working at heights or with ladders
Injuries from dropping tools and equipment
Contact with AC wiring
Mounting Strategies
When choosing mounting locations, consider the available mounting structures and antenna
clearance. The router should always be mounted with the top of the unit horizontal and level and
with the antennas facing upward.
It is usually best to attach ground and data cables to the router prior to mounting. Before
mounting the router, review the wiring instructions in “Grounding the Router” on page 21 and
“Connecting Data Cables” on page 18 to determine the best strategy for the selected location.
Note
To eliminate potential interference from the mounting structure, the router should be
mounted with at least 4 feet of clearance around the antennas.

Mounting Strategies
Tropos MetroMesh Routers Installation Guide, Models 6310 and 6320 7
Acceptable options for mounting on a streetlight are shown in Figure 2. In each case the router is
mounted to assure clearance for the antennas above the height of the streetlight.

Proper Use of Clamps
Tropos MetroMesh Routers Installation Guide, Models 6310 and 6320 8
Proper Use of Clamps
The mounting assembly contains a clamp to secure the router to the mounting structure. Figure 3
illustrates the proper use of the clamp. The clamp must be routed through a slot in the pole
bracket as shown in the figure, and then attached to the pole and tightened.
The pole bracket should be leveled before it is secured to the pole.

Pole, Tower, and Streetlight Mounting Instructions
Tropos MetroMesh Routers Installation Guide, Models 6310 and 6320 9
Pole, Tower, and Streetlight Mounting Instructions
This section explains how to mount the router on a pole, tower, or streetlight. It is best to mount
the router to aluminum or galvanized steel structures. The mounting brackets are designed to
pierce any oxidation layers that are on the outside of the pole, thereby assuring good quality
connection to the grounded structure.
Due to potential antenna obstruction issues, the router is not designed to be directly mounted on
a building wall. If it is necessary to mount the router on a wall, follow the instructions for
mounting on a wooden pole (“Wood Pole Mounting” on page 13), and attempt to mount the
router with maximum possible clearance around the antennas.
Note
The router should always be mounted with the top of the router horizontal and level and with the
antennas facing upward.
Note
It is best to attach ground and data cables to the router before sliding the router into the mounting
bracket, as explained in this section. Before mounting the router, review the wiring instructions in
“Grounding the Router” on page 21 and “Connecting Data Cables” on page 18 to determine the best
strategy for the selected location.
Note
Mounting to wood, concrete, or painted poles may require primary grounding for the unit. Check the
national electrical codes in your area for specific rules.
