Accessories

IO Expander

The IO expander is a cnReach module with no radios. It can be used to add Serial or Analog/Digital I/O to a

broadband network or additional I/O to a narrowband network. It is managed and configured in the same way as

a cnReach radio from a networking and management perspective.

NB-N500006B-US N500 AC to 24 VDC Power Supply with US line cord

NB-N500011B-GL N500 AC to 24 VDC Power Supply (no line cord)

Each cnReach radio module ships with a power connector and an I/O connector. The model listed here are for

spares purposes to replace lost or damaged connectors. Pictured below are the spare power connector and

spare I/O connector.

DINRailMount

The DIN Rail Mount allows for mounting the cnReach module on a standard DIN rail.

cnReach™ N500 QUICK START GUIDE

PAGE 10

Power Supplies

Cambium offers two power supplies for cnReach. The first is an AC brick useful for bench testing or temperature

controlled environments. The second is a DIN rail supply that covers a wide temperature range and is

mountable in a NEMA enclosure next to a cnReach DIN mounted radio.

Attention The DIN-rail supply does NOT come with a line cord. Also note the availability of the

‘brick’ supply without a line cord for import into countries using a non-U.S. style cord

Antennas

Cambium Networks offers a range of antenna options and installation kits to assist in the deployment of a

complete system.

For bench testing and trials, a series of ‘whip’ low-gain omni antennas is available for each band.

NB-N500008A-US N500 900 MHz Whip Antenna

NB-N500009A-US N500 700 MHz Whip Antenna

NB-N500010A-US N500 450 MHz Whip Antenna

NB-N500012A-US N500 220 MHz Whip Antenna

cnReach™ N500 QUICK START GUIDE

PAGE 11

These whip antennas generally net out to unity gain or close to 0 dB. Pictured below are the whip antennas

from left to right (220 MHz, 450 MHz, 700 MHz and 900 MHz)

Note that the 220 MHz and 450 MHz whip antennas need to be trimmed to the correct length for optimal

frequency matching. An instruction sheet is included with each antenna to indicate the correct length. Those

instruction sheets are pictured below:

cnReach™ N500 QUICK START GUIDE

PAGE 12

In addition to the whip antennas, Cambium provides a selection of Yagi antennas and an omni antenna for field

deployments. Specification sheets for these antennas are available on the Cambium website.

Obtaining an Unknown IP Address

The IP address of the radio can be changed by the user at any time. It is also possible to assign different IP

addresses to each interface; Eth1, Eth2, Radio1, Radio2 when using layer 3 routing. If the IP address of the radio

is unknown, the CLI can be used to either discover the IP or default the radio back to the factory default IP

address and configuration.

Attention Defaulting the radio via the CLI will also default the radio RF and radio network

settings, which will bring down any active RF connections.

If your computer is on the same subnet as the default radio IP address and communications cannot be

established, it‘s possible the IP address of the radio has changed. This is a common situation with previously-

installed radios.

Note It is good practice to apply light colored electrical tape to the underside of the radio to

track any IP address changes with a marker.

Use the following equipment to obtain the IP address you need:

•Serial to USB cable

•Standard CAT5 Ethernet cable

•cnReach N500 DB-9 to RJ-45 adapter

cnReach™ N500 QUICK START GUIDE

PAGE 16

Connect the Serial to USB cable to the computer and install the drivers per the manufacturer instructions

(unless the Operating System recognizes the device).

Note the COM Port number allocated to the device by the operating system.

Connect the RJ-45 to DB9 adapter to the DB9 Serial port on the Serial to USB cable.

Plug the CAT5 Ethernet cable into the RJ-45 to DB9 adapter.

Look at the SERIAL ports on the Enclosed radio. The SERIAL port that has the blinking Orange LED is

the CLI port. Plug in the Cat5 Ethernet cable.

Attention!cnReach N500 radios use RJ-45 connectors for both Serial and Ethernet ports. This

means it is possible to plug an Ethernet cable into a Serial port and vice versa.

Open a terminal emulator such as Teraterm, PuTTY or HyperTerminal and connect to the PC’s COM Port at

115200 8N1.

Press Enter. You will be prompted to log in. Username: admin

Type show ifconfig. The default Interface configuration (bridge) lists an IP address for VLAN1 only.

cnReach™ N500 QUICK START GUIDE

PAGE 17

If the radio configuration is routed, it is possible for each interface to have a unique IP address. This time,

show ifconfig will return the IP address of each physical interface.

The User Interface can be accessed at either the Eth1/Eth2 interface IP via a direct connection to that

interface.

Note The Laptop/PC should be given a fixed IP address on the same subnet as the connected

interface in order to establish Ethernet communications.

Mounting the cnReach Module

The cnReach module can be placed on a horizontal surface or onto a DIN-Rail with option DIN-rail mount option.

cnReach radios MUST be installed in weather-proof cabinet or indoors. cnReach modules are not meant for

outdoor deployments.

Warning

Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to

radiate RF energy as soon as they are powered up.

Observe the following guidelines:

Never work in front of the antenna when the cnReach module is powered.

Always remove power from the cnReach module before connecting or disconnecting the

drop cable the antenna.

Deployment Process

Successful network deployments are those that are installed predictably, perform well over time and recover

from unexpected conditions quickly. Our experience troubleshooting networks taught us to plan, install and

troubleshoot networks with the considerations listed below. Follow these steps to deploy a successful network.

Planning

•Understand customer’s application and required network throughput. This is especially important when

working with narrow-band channels on licensed spectrum. Take into account the polling cycles and the

sizes of each poll especially when planning PMP networks.

•Test radios on the bench with desired equipment before first deployment. This is especially important

when interfacing with serial or general-purpose IO equipment to confirm wiring diagrams, cables and

cnReach module settings.

•Perform a path study for each link using Cambium Networks LINKPlanner.

•Plan radio settings to achieve desired network throughput with consideration of expected signal strength,

RF noise and overlapping networks.

•Perform a Site Survey to sample in-band noise levels.

•Prepare equipment list that includes radios, radio accessories, cables, connectors, adapters, antennae,

towers/poles, brackets, etc.

•LINKPlanner imports path profiles and predicts data rates and reliability over the path. It allows the system

designer to try different antenna heights and RF power settings. It outputs an installation report that

defines the parameters to be used for configuration, alignment and operation. Use the installation report

to compare predicted and actual link performance.

Site Survey

A site survey involves using a spectrum analyzer or alternative spectrum tool to check in-band noise levels at the

site.

•Cambium Networks considers this an important step when deploying standard networks since the in-band

noise levels can be factored into the network design.

•Other aspects of a site survey include sweeping any existing installed coaxial transmission line, jumpers,

surge suppressors and antennas for Return Loss or VSWR.

•Identifying possible causes of interference with co-located systems.

Installation

•Use compass to align antennae to magnetic azimuth as recommended by the LINKPlanner installation

report

•Fine-tune the alignment by monitoring the results of the RF Ping diagnostic tool in the GUI to optimize the

displayed RSSi value. This value can be compared to the predicted value in LINKPlanner. Any deviations

from the LINKPlanner prediction should be justified before completing the installation.

•Properly torque all mechanical connections.

•Apply appropriate weatherproofing material to all exposed RF and electrical connections.
