Installation Guide 5

1 Introduction

EMG101 Gateways are components of Symbol Technologies Wireless Controller System. An EMG101 Gateway
links to wireless 802.15.4 electronic shelf label tags. It installs in minutes anywhere a CAT-5e (or better) cable is
located.

The EMG101 Gateway ships with two single-band 2.4GHz 802.15.4 radios. The radios are configured for redundant
operation. If the currently operating radio fails, the gateway will automatically activate the second radio.

The EMG101 Gateway is approved under MODEL: EMG101.
Symbol recommends the EMG101 Gateway receive power and transfer data through the same CAT-5e (or better)

Ethernet cable using a Symbol Power Injector. The Power Injector ((Part No. AP-PSBIAS-2P2-AFR) is an 802.3af PoE
injector. For information, see

A separate power supply (Part No. PWRS-147376-01R) is also available if you do not wish to use a Power Injector.
This standard power supply just supplies power to the EMG101 Gateway’s power connector and does not converge
power and Ethernet within a single cable connection.

1.1 Document Conventions

The following graphical alerts are used in this document to indicate notable situations:

Power Injector System.

NOTE Tips, hints, or special requirements that you should take note of.

CAUTION Care is required. Disregarding a caution can result in data loss or

equipment malfunction.

WARNING! Indicates a condition or procedure that could result in personal injury or

equipment damage.

1.2 Warnings

• Read all installation instructions and site survey reports, and verify correct equipment installation before
connecting the EMG101 Gateway.

• Remove jewelry and watches before installing this equipment.

• Verify any device connected to this unit is properly wired and grounded.

• Verify there is adequate ventilation around the device, and that ambient temperatures meet equipment
operation specifications.

1.3 Site Preparation

To prepare your deployment site for gateway installation:

• Consult your site survey and network analysis reports to determine specific equipment placement, power

drops, and so on.

• Assign installation responsibility to the appropriate personnel.

• Identify and document where all installed components are located

• Ensure adequate, dust-free ventilation to all installed equipment

• Prepare Ethernet port connections

• Verify cabling is within the maximum 100 meter allowable length

1.4 Package Contents

The EMG101 Gateway ships with the following:

• ESL101 Gateway

• Installation Guide (This Guide)

• Rubber Wall Mount Spacers (4)

• Wall mount screw and anchor kit

1.5 Features

• One RJ-45 console connector

• LED indicator

• Safety wire tie point

• Wall mount slots

• Clips for suspended T-Bar mounting

• DC power connector

An EMG101 Gateway has one RJ-45 connector supporting an 10/100/1000 Ethernet port connection and requires

802.3af compliant power from an external source.

The EMG101 Gateway contains runtime firmware which enables the unit to boot after either a power up or a
watchdog reset. The runtime firmware on the gateway can be updated via the Ethernet interface.

Installation Guide 7

2 Hardware Installation

2.1 Installation Instructions

The EMG101 Gateway can attach to a wall or mount under a suspended T-Bar. Select a mounting option based on
the physical environment of the coverage area. Do not mount the EMG101 Gateway in a location not approved in
a site survey.

To prepare for the installation:

1. Verify the contents of the box includes the intended EMG101 Gateway and accessory hardware.

2. Review site survey and network analysis reports to determine the location and mounting position for the
EMG101 Gateway.

3. Connect a CAT-5 or better Ethernet cable to a PoE compatible device and run the cable to the installation
site. Ensure there is sufficient cable slack to perform the installation steps.

4. Determine whether the EMG101 Gateway is powered using a Power Injector system, combining data and
power to the Gateway’s GE1/PoE port or will be powered from a conventional power adapter providing
power only to the Gateway’s DC-48V connector.

2.2 Precautions

Before installing the EMG101 Gateway:

• Verify the intended deployment location is not prone to moisture or dust.

• Verify the environment has a continuous temperature range between 0° C to 50° C.

2.3 EMG101 Gateway Placement

For optimal performance, install the EMG101 Gateway away from transformers, heavy-duty motors, fluorescent
lights, microwave ovens, refrigerators and other industrial equipment. Signal loss can occur when metal, concrete,
walls or floors block transmission. Install the EMG101 Gateway in an open area or add additional gateways as
needed to improve coverage.

Antenna coverage is analogous to lighting. Users might find an area lit from far away to be not bright enough. An
area lit sharply might minimize coverage and create dark areas. Uniform antenna placement in an area (like even
placement of a light bulb) provides even, efficient coverage.

Place the EMG101 Gateway using the following guidelines:

• Install the EMG101 Gateway at an ideal height of 10 feet from the ground.

• Orient the EMG101 Gateway antennas (Part Number ML-2452-APA2-01) vertically for best reception.

• Point the EMG101 Gateway antennas downward if attaching to the ceiling.

To maximize the EMG101 Gateway’s radio coverage area, Symbol recommends conducting a site survey to define
and document radio interference obstacles before installing the EMG101 Gateway.

2.4 Power Injector System

The EMG101 Gateway can receive power via an Ethernet cable connected to the GE1/PoE port.

When users purchase an Electronic Shelf Label (ESL) solution, they often need to place EMG101 Gateways in
obscure locations. Power can be supplied from a dedicated connection or from a PoE injector. The Power Injector
merges power and Ethernet into one cable, reducing the burden of installation and allowing optimal EMG101
Gateway placement in respect to the intended coverage area.

The Power Injector (Part No. AP-PSBIAS-2P2-AFR) is an 802.3af PoE injector. The EMG101 Gateway can only use a
Power Injector when connecting to the EMG101 Gateway’s GE1/PoE port. The Power Injector is separately ordered
and not shipped with the EMG101 Gateway. A separate Power Injector is required for each EMG101 Gateway
comprising the network.

Installation Guide 9

The Power Injector has no On/Off power switch. The Injector receives power and is ready for device connection and
operation as soon as AC power is applied. Refer to the Installation Guide shipped with the Power Injector for a
description of the device’s LED. The Power Injector can be installed free standing, on an even horizontal surface or
wall mounted using the Power Injector’s wall mounting key holes.

The following guidelines should be adhered to before cabling the Power Injector to an Ethernet source and an
EMG101 Gateway:

• Do not block or cover airflow to the Power Injector.

• Keep the Power Injector away from excessive heat, humidity, vibration and dust.

• The Power Injector isn’t a repeater, and does not amplify the Ethernet signal. For optimal performance,
ensure the Power Injector is placed as close as possible to the Ethernet switch. This allows the EMG101
Gateway to be deployed away from power drops.

• Ensure the cable length from the Ethernet source (host) to the Power Injector and EMG101 Gateway does
not exceed 100 meters (333 ft).

CAUTION To avoid problematic performance and restarts, disable PoE from a

wired controller port connected to an EMG101 Gateway if mid-span
power sourcing equipment (PSE) is used between the two, regardless
of the manufacturer.

CAUTION Ensure AC power is supplied to the Power Injector using an AC cable

with an appropriate ground connection approved for the country of
operation.
