Safety and regulatory information

This section describes important safety and regulatory guidelines that must be observed by personnel installing or operating ePMP equipment.

IMPORTANT SAFETY INFORMATION

Warning

To prevent loss of life or physical injury, observe the safety guidelines in this section.

Power lines

Exercise extreme care when working near power lines.

Working at heights

Exercise extreme care when working at heights.

Grounding and protective earth

ePMP devices and mounting structures must be properly grounded to protect against lightning. It is the user’s responsibility to install the equipment in accordance with national regulations. In the USA, follow Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA). In Canada, follow Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. Other regulations may apply in different countries and therefore it is recommended that installation be contracted to a professional installer.

Powering down before servicing

Always power down and unplug the equipment before servicing.

Primary disconnect device

The ePMP power supply is the primary disconnect device.

External cables

Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the outdoor environment.

RF exposure near the antenna

Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the power to the ePMP device before undertaking maintenance activities in front of the antenna.

Minimum separation distances

Install the ePMP device so as to provide and maintain the minimum separation distances from all persons.

The minimum separation distances for each frequency variant are specified in Calculated distances

and power compliance margins on page 160.

CAMBIUM NETWORKS

000v013

IMPORTANT REGULATORY INFORMATION

The ePMP product is certified as an unlicensed device in frequency bands where it is not allowed to cause interference to licensed services (called primary users of the bands).

Radar avoidance

In countries where radar systems are the primary band users, the regulators have mandated special requirements to protect these systems from interference caused by unlicensed devices. Unlicensed devices must detect and avoid co-channel operation with radar systems.

The ePMP provides detect and avoid functionality for countries and frequency bands requiring protection for radar systems.

Installers and users must meet all local regulatory requirements for radar detection. To meet these requirements, users must set the correct country code during commissioning of the ePMP equipment. If this is not done, installers and users may be liable to civil and criminal penalties.

Contact the Cambium helpdesk if more guidance is required.

Specific expertise and training required for professional installers

To ensure that the ePMP is installed and configured in compliance with the requirements of Industry Canada and the FCC, installers must have the radio engineering skills and training described in this section. This is particularly important when installing and configuring an ePMP system for operation in the 5 GHz band (5150 – 5250 MHz – FCC only, 5250 – 5350 MHz, 5470 – 5725 MHz and 5725 – 5850 MHz).

Ethernet networking skills

The installer must have the ability to configure IP addressing on a PC and to set up and control products using a web browser interface.

Lightning protection

To protect outdoor radio installations from the impact of lightning strikes, the installer must be familiar with the normal procedures for site selection, bonding and grounding. Installation guidelines for the ePMP can be found in section System planning on page 32.

Training

The installer needs to have basic competence in radio and IP network installation. The specific requirements applicable to the ePMP must be gained by reading this user guide and by performing sample setups at base workshop before live installations.

Product description

This chapter provides a high level description of the ePMP product. It describes the function of the product, the main product variants and typical installation. It also describes the main hardware components.

The following topics are described in this chapter:

 The key features, typical uses, product variants and components of the ePMP are explained in

Overview of ePMP on page 14.

 How the ePMP wireless link is operated, including modulation modes, power control and

security is described under Wireless operation on page 15.

 The ePMP management system, including the web interface, installation, configuration, alerts

and upgrades is described in System management on page 17.

Overview of ePMP

This section introduces the key features, typical uses, product variants and components of the ePMP portfolio as a whole (802.11n and 802.11ac products).

PURPOSE – EPMP PORTFOLIO

Cambium ePMP Series products are designed for Ethernet bridging over point-to-multipoint and point-to-point microwave links in the unlicensed 2.4 GHz, 2.5 GHz (Brazil only), and 5 GHz bands. Users must ensure that the ePMP Series complies with local operating regulations.

Force 300-25 devices support point-to-point microwave links in the unlicensed 5 GHz band.

The ePMP Series acts as a transparent bridge between two segments of the operator and customers’ networks. In this sense, it can be treated as a virtual wired connection between the Access Point and the Subscriber Module. The ePMP Series forwards 802.3 Ethernet packets destined for the other part of the network and filters packets it does not need to forward.

KEY FEATURES

Force 300-25

Force 300-25 is a rugged high-capacity outdoor point-to point link wireless device in the unlicensed 5 GHz frequency bands with a maximum UDP throughput of 500+ Mbps (when operating with 80 MHz channel bandwidth). It is capable of operating in line-of-sight (LOS) and near-LOS conditions. Force 300-25 is available as an integrated unit with a dual-polarized 25 dBi narrow Beamwidth dish antenna. One point-to-point link consists of two Force 300-25 devices.

Force 300-25 is based on highly-integrated wireless semiconductor components designed to meet the IEEE 802.11ac standard, however the Force 300-25 device has a proprietary air interface for the main point-to-point link.

Force 300-25 is powered by standard power-over-Ethernet to a 1000Base-T port.

Management of the unit is conducted via the same interface as the bridged traffic (in-band Management).

A summary of the main Force 300-25 characteristics is listed under Table 1.

TYPICAL INSTALLATION EQUIPMENT

The Force 300-25 is a solution consisting of integrated outdoor units, indoor power supply units/LAN injectors, cabling and surge suppression equipment.

The main hardware components of a Force 300-25 installation are as follows:

 Force 300-25 Integrated Radio: An integrated outdoor transceiver unit containing all the radio,

networking, and surge suppression electronics.

 Force 300-25 Power Supply: An indoor power supply module providing Power-over-Ethernet

(PoE) supply and 100/1000 Base-T to the Force 300-25 device.

 Force 300-25 Radio Cabling and lightning protection: Shielded Cat5e cables, grounding cables,

and connectors.

For more information about these components, including interfaces, specifications and Cambium part numbers, see System hardware on page 20.

Wireless operation

This section describes how the ePMP wireless link is operated, including modulation modes, power control and security.

TIME DIVISION DUPLEXING

TDD cycle

ePMP links operate using Time Division Duplexing (TDD). The links employ a TDD cycle in which the Access Point determines which Subscriber Modules may transmit and when based on the configured downlink/uplink ratio (duty cycle). Three fixed Downlink/Uplink frame ratios are available – 75/25, 50/50 and 30/70.

OFDM AND CHANNEL BANDWIDTH

The Force 300-25 transmits using Orthogonal Frequency Division Multiplexing (OFDM). This wideband signal consists of many equally spaced sub-carriers. Although each sub carrier is modulated at a low rate using conventional modulation schemes, the resultant data rate from all the sub-carriers is high.

The channel bandwidth of the OFDM signal is 20 MHz, 40 MHz or 80 MHz, based on operator configuration.

CAMBIUM NETWORKS

000v013

Each channel is offset in center frequency from its neighboring channel by 5 MHz.

ADAPTIVE MODULATION

The Force 300-25 can transport data over the wireless link using a number of different modulation modes ranging from 256-QAM to QPSK. For a given channel bandwidth and TDD frame structure, each modulation mode transports data at a fixed rate. Also, the receiver requires a given signal to noise ratio in order to successfully demodulate a given modulation mode. Although the more complex modulations such as 256-QAM will transport data at a much higher rate than the less complex modulation modes, the receiver requires a much higher signal to noise ratio.

The Force 300-25 provides an adaptive modulation scheme where the receiver constantly monitors the quality of the received signal and notifies the far end of the link of the optimum modulation mode with which to transmit. In this way, optimum capacity is achieved at all times.

MIMO

Multiple-Input Multiple-Output (MIMO) technique provides protection against fading and increases the probability of a received decoded signal to be usable.

RADAR AVOIDANCE

In regions where protection of radars is part of the local regulations, the ePMP must detect interference from radar-like systems and avoid co-channel operation with these systems.

To meet this requirement, the ePMP implements the following features:

 The equipment can only transmit on available channels, of which there are none at initial

power up. The radar detection algorithm will always scan a usable channel for 60 seconds for radar interference before making the channel an available channel.

 This compulsory channel scan will mean that there is at least 60 seconds service outage every

time radar is detected and that the installation time is extended by at least 60 seconds even if there is found to be no radar on the channel

There is a secondary requirement for bands requiring radar avoidance. Regulators have mandated that products provide a uniform loading of the spectrum across all devices. In general, this prevents operation with fixed frequency allocations. However:

 ETSI regulations do allow frequency planning of networks (as that has the same effect of

spreading the load across the spectrum).

 The FCC does allow channels to be avoided if there is actually interference on them.

Note

When operating in a region which requires DFS, ensure that the AP is configured with alternate frequencies and that the SM is configured to scan for these frequencies to avoid long outages.

ENCRYPTION

The ePMP supports optional encryption for data transmitted over the wireless link. The encryption algorithm used is the Advanced Encryption Standard (AES) with 128-bit key size. AES is a symmetric encryption algorithm approved by U.S. Government organizations (and others) to protect sensitive information.

CAMBIUM NETWORKS

000v013

COUNTRY CODES

Some aspects of wireless operation are controlled, enforced or restricted according to a country code. ePMP country codes represent individual countries (for example Denmark) or regulatory regions (for example FCC or ETSI).

Country codes affect the following aspects of wireless operation:

 Maximum transmit power  Radar avoidance (future release)  Frequency range

Caution

To avoid possible enforcement action by the country regulator, always operate links in accordance with local regulations

FORCE 300-25 HEATER

At startup, if the Force 300-25 module temperature is at or below 32° F (0° C), an internal heater is activated to ensure that the device is able to successfully begin operation. The unit’s heater is only activated when the unit is powered on and will not apply heat to the device once startup is complete. When the unit temperature is greater than 32° F (0° C), the heater is deactivated and the unit continues its startup sequence.

The effect on device startup time at various temperatures is defined in Table 7.

FORCE 300-25 WIND LOADING

Ensure that the device and the structure on which it is mounted are capable of withstanding the prevalent wind speeds at a proposed ePMP site. Wind speed statistics are available from national meteorological offices.

The device and its mounting bracket are capable of withstanding wind speeds of up to 200 kph (124 mph).

Wind blowing on the device will subject the mounting structure to significant lateral force. The magnitude of the force depends on both wind strength and surface area of the device. Wind loading is estimated using the following formulae:

Force (in kilograms) = 0.1045aV2

System planning

This chapter provides information to help the user to plan an ePMP link.

The following topics are described in this chapter:

 How to plan ePMP links to conform to the regulatory restrictions that apply in the country of

operation is explained under Radio spectrum planning on page 32.

 Factors to be considered when planning links such as range, path loss and throughput are

described under Link planning on page 34.

 The grounding and lightning protection requirements of a ePMP installation are described

under Grounding and lightning protection on page 20.

 Factors to be considered when planning ePMP data networks are described under Data

network planning on page 35.

Radio spectrum planning

This section describes how to plan ePMP links to conform to the regulatory restrictions that apply in the country of operation.

Caution

The user must ensure ePMP product operates in accordance to local regulatory limits.

Note

Contact the applicable radio regulator to check if registration of the ePMP link is required.

GENERAL WIRELESS SPECIFICATIONS

REGULATORY LIMITS

The local regulator may restrict frequency usage and channel width and may limit the amount of conducted or radiated transmitter power.

Many countries impose EIRP limits (Allowed EIRP) on products operating in the bands used by the ePMP Series. For example, in the 5 GHz band, these limits are calculated as follows:

 In the 5.8 GHz band (5725 MHz to 5875 MHz), the EIRP must not exceed the lesser of 36 dBm or

(23 + 10 x Log Channel width in MHz) dBm.

Some countries (for example the USA) impose conducted power limits on products operating in the 5 GHz band.

CONFORMING TO THE LIMITS

Ensure the link is configured to conform to local regulatory requirements by configuring the correct country code (located in the web management interface, under Configure > Radio). In the following situations, the country code does not automatically prevent operation outside the regulations:

 When operating in ETSI regions, it is required to enter a license key in the ePMP web

management interface to unlock valid country-specific frequencies. This key may be obtained from https://support.cambiumnetworks.com/licensekeys/epmp.

AVAILABLE SPECTRUM

The available spectrum for operation depends on the region. When configured with the appropriate country code, the unit will only allow operation on those channels which are permitted by the regulations.

Certain regulations have allocated certain channels as unavailable for use:

 Some European countries have allocated part of the 5.8 GHz band to Road Transport and

Traffic Telematics (RTTT) systems.

Where regulatory restrictions apply to certain channels, these channels are barred automatically by the use of the correct country code. For example, at 5.8 GHz in some European countries, the RTTT band 5795 MHz to 5815 MHz is barred. With the appropriate country code configured for this region, the ePMP will not operate on channels within this band.

The number and identity of channels barred by the license key and country code is dependent on the channel bandwidth.

CAMBIUM NETWORKS

000v013

CHANNEL BANDWIDTH

Select the required channel bandwidth for the link. The selection depends upon the ePMP frequency variant and country code, as specified on page 164.

The wider a channel bandwidth the greater is its capacity. As narrower channel bandwidths take up less spectrum, selecting a narrow channel bandwidth may be a better choice when operating in locations where the spectrum is very busy.

Both ends of the link must be configured to operate on the same channel bandwidth.

Link planning

This section describes factors to be taken into account when planning links, such as range, obstacles path loss and throughput.

RANGE AND OBSTACLES

Calculate the range of the link and identify any obstacles that may affect radio performance.

Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the risk of interference. This information is necessary in order to achieve an accurate link feasibility assessment.

PATH LOSS

Path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. The path loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal (Fade Margin). The following calculation needs to be performed to judge whether a particular link can be installed:

capability

Equipment Capability (dB)

Free space path loss is a major determinant in received (Rx) signal level. Rx signal level, in turn, is a major factor in the system operating margin (fade margin), which is calculated as follows:

System Operating Margin (fade margin) dB = Rx signal level (dB) – Rx sensitivity (dB)

Thus, the fade margin is the difference between strength of the received signal and the strength that the receiver requires for maintaining a reliable link.

CAMBIUM NETWORKS

000v013

ADAPTIVE MODULATION

Adaptive modulation ensures that the highest throughput that can be achieved instantaneously will be obtained, taking account of propagation and interference. When the link has been installed, web pages provide information about the link loss currently measured by the equipment, both instantaneously and averaged.

This section describes factors to be considered when planning ePMP data networks.

Note

Practical Ethernet rates will depend on network configuration, higher layer protocols and platforms used.

Over the air throughput will be capped to the rate of the Ethernet interface at the receiving end of the link.

MANAGEMENT VLAN

Decide if the IP interface of the device management agent will be connected in a VLAN. If so, decide if this is a standard (IEEE 802.1Q) VLAN or provider bridged (IEEE 802.1ad) VLAN, and select the VLAN ID for this VLAN.

Use of a separate management VLAN is strongly recommended. Use of the management VLAN helps to ensure that the device management agent cannot be accessed by customers.

QUALITY OF SERVICE FOR BRIDGED ETHERNET TRAFFIC

Decide how quality of service will be configured in ePMP to minimize frame loss and latency for high priority traffic. Wireless links often have lower data capacity than wired links or network equipment like switches and routers, and quality of service configuration is most critical at network bottlenecks.

CAMBIUM NETWORKS

000v013

ePMP provides three priority types for traffic waiting for transmission over the wireless link – Voice, High and Low. Low is the lowest priority and Voice is the highest priority. Traffic is scheduled using strict priority; in other words, traffic in a given priority is transmitted when all higher-priority transmissions are complete.

Caution

ePMP supports Automatic Transmit Power Control (ATPC) where the Subscriber Module devices are instructed by the Access Point to adjust their Tx power in order for the Subscriber Module device signal (UL RSSI) to arrive at the Access Point at a predetermined RSSI level (configurable on the Access Point under Configuration>Radio>Power Control>Subscriber Module Target Receive Level). This feature is beneficial to keep the overall noise floor in the sector to an acceptable level. However, the feature negates the purpose of eAlign measurements on the Access Point device since, during the alignment, the Subscriber Module may constantly change its Tx power. It is recommended to turn off ATPC and set the Subscriber Module Tx power to maximum allowable power during alignment.

While aligning the link using eAlign, please follow these steps:

Procedure:

On the Subscriber Module, set Configuration>Radio>Power Control>Max Tx Power to Manual.

Set Configuration>Radio>Power Control>Transmitter Power to 26 dBm (or maximum value allowed by regulations).

Operation and Troubleshooting

This chapter provides instructions for operators of ePMP networks. The following topics are described:

 General Planning for Troubleshooting on page 89  Upgrading device software on page 89  Testing hardware on page 90  Troubleshooting the radio link on page 92  Resetting ePMP to factory defaults by power cycling on page 93

General Planning for Troubleshooting

Effective troubleshooting depends in part on measures that you take before you experience trouble in your network. Cambium recommends the following measures for each site:

Procedure:

Identify troubleshooting tools that are available at your site (such as a protocol analyzer).

Identify commands and other sources that can capture baseline data for the site. These may include:

 Ping  tracert or traceroute  Throughput Test results  Throughput data  Configure GUI page captures  Monitor GUI page captures  Session logs

Start a log for the site, including:

 Operating procedures  Site-specific configuration records  Network topology  Software releases  Types of hardware deployed  Site-specific troubleshooting process  Escalation procedures  GPS latitude/longitude of each network element

Upgrading device software

To take advantage of new features and software improvements for the ePMP system, monitor the Cambium Networks PMP Software website: https://support.cambiumnetworks.com/files/epmp

To upgrade the device software, follow this procedure:

CAMBIUM NETWORKS

000v013

Procedure:

Navigate to page Tools, Software Upgrade

Under the Main Software section, set the Upgrade Option to URL to pull the software file from a network software server or select Local File to upload a file from the accessing device. If URL is selected, enter the server IP address, Server Port, and File path.

If Local File is selected, click Browse to launch the file selection dialogue

Click Upgrade

Caution

Do not power off the unit in the middle of an upgrade process.

Once the software upgrade is complete, click the Reset icon.

Testing hardware

This section describes how to test the hardware when it fails on startup or during operation.

Before testing hardware, confirm that all outdoor cables, that is those that connect the device to equipment inside the building, are of the supported type, as defined in Ethernet cabling on page 31

CHECKING THE POWER SUPPLY LED

When the power supply is connected to the main power supply, the expected LED behavior is:

 The Power (green) LED illuminates steadily.

If the expected LED operation does not occur, or if a fault is suspected in the hardware, check the LED states and choose the correct test procedure:

 Power LED is off on page 90  Ethernet LED is off on page 90

POWER LED IS OFF

Meaning: Either the power supply is not receiving power from the AC/DC outlet, or there is a wiring fault in the unit.

Action: Remove the device cable from the PSU and observe the effect on the Power LED. If the Power LED does not illuminate, confirm that the mains power supply is working, for example, check the plug. If the power supply is working, report a suspected power supply fault to Cambium Networks.

ETHERNET LED IS OFF

Meaning: There is no Ethernet traffic between the device and power supply.

Action: The fault may be in the LAN or device cable:

 Remove the LAN cable from the power supply, examine it and confirm it is not faulty.  If the PC connection is working, remove the AP/SM cable from the power supply, examine it,

and check that the wiring to pins 1,2 and 3,6 is correct and not crossed.

CAMBIUM NETWORKS

Test Ethernet packet errors reported by the device

Log into the device and click Monitor, Performance. Click Reset System Counters at the bottom of the page and wait until LAN RX – Total Packet Counter has reached 1 million. If the counter does not increment or increments too slowly, because for example the ePMP system is newly installed and there is no offered Ethernet traffic, then abandon this procedure and consider using the procedure Test ping packet loss on page 91.

Check the LAN RX – Error Packet Counter statistic. The test has passed if this is less than 10.

Test Ethernet packet errors reported by managed switch or router

If the device is connected to a managed Ethernet switch or router, it may be possible to monitor the error rate of Ethernet packets. Please refer to the user guide of the managed network equipment. The test has passed if the rate of packet errors reported by the managed Ethernet switch or router is less than 10 in 1 million packets.

Test ping packet loss

Using a computer, it is possible to generate and monitor packets lost between the power supply and the AP/SM. This can be achieved by executing the Command Prompt application which is supplied as standard with Windows and Mac operating systems.

Caution

This procedure disrupts network traffic carried by the device under test.

Procedure:

1. Ensure that the IP address of the computer is configured appropriately for connection to the

device under test, and does not conflict with other devices connected to the network.

2. If the power supply is connected to an Ethernet switch or router then connect the computer to a

spare port, if available.

3. If it is not possible to connect the computer to a spare port of an Ethernet switch or router, then

the power supply must be disconnected from the network in order to execute this test:

 Disconnect the power supply from the network.  Connect the computer directly to the LAN port of the power supply.

4. On the computer, open the Command Prompt application.

5. Send 1000 ping packets of length 1500 bytes. The process will take 1000 seconds, which is

approximately 17 minutes.

If the computer is running a Windows operating system, this is achieved by typing (for an IPv6 address, use the ping6 command):

ping –n 1000 –l 1500 <ipaddress>

where <ipaddress> is the IP address of the AP or SM under test.

If the computer is running a MAC operating system, this is achieved by typing:

ping –c 1000 –s 1492 <ipaddress>

where <ipaddress> is the IP address of the AP/SM under test.

6. Record how many Ping packets are lost. This is reported by Command Prompt on completion of

the test.

The test has passed if the number of lost packets is less than 2.

Troubleshooting the radio link

This section describes how to test the link when there is no radio communication, when it is unreliable, or when the data throughput rate is too low. It may be necessary to test both ends of the link.

MODULE HAS LOST OR DOES NOT ESTABLISH RADIO CONNECTIVITY

If there is no wireless activity, follow this:

Procedure:

Check that the devices are configured with the same Frequency Carrier.

Check that the Channel Bandwidth is configured the same at both ends of the link.

On the Access Point, verify that the Max Range setting is configured to a distance slightly greater than the distance between the Access Point and the other end of the link.

Check that the Access Point Synchronization Source is configured properly based on the network configuration.

Verify the authentication settings on the devices. if Authentication Type is set to WPA2, verify that the Pre-shared Key matches between the Access Point and the Subscriber Module Preferred Access Points List.

Check that the software at each end of the link is the same version.

Check that the desired Access Point SSID is configured in the Subscriber Module Preferred Access Points List.

On the Subscriber Module, check the DL RSSI and DL CINR values. Verify that for the Subscriber Module installed distance, that the values are consistent with the values reported by the LINKPlanner tool.

Check Tx Power on the devices

Check that the link is not obstructed or misaligned.

Check the DFS status page (Monitor, System Status) at each end of the link and establish that there is a quiet wireless channel to use.

If there are no faults found in the configuration and there is absolutely no wireless signal, retry the installation procedure.

If this does not work then report a suspected device fault to Cambium Networks.

CAMBIUM NETWORKS

000v013

LINK IS UNRELIABLE OR DOES NOT ACHIEVE DATA RATES REQUIRED

If there is some activity but the link is unreliable or does not achieve the data rates required, proceed as follows:

Procedure:

Check that the interference has not increased by monitoring the uplink and downlink CINR values reported in the Access Point page Monitor, Wireless Status

Check that the RSSI values reported at the device are proper based on the distance of the link – the LINKPlanner tool is designed to estimate these values.

Check that the path loss is low enough for the communication rates required.

Check that the device has not become misaligned.

Review your Quality of Service configuration and ensure that traffic is properly classified and prioritized.

Resetting ePMP to factory defaults by power cycling

Operators may reset an ePMP radio to default factory configuration by a sequence of power cycling (removing and re-applying power to the device). This procedure allows operators to perform a factory default reset without a tower climb or additional tools. The procedure is depicted in Figure 25.

Procedure:

Remove the Ethernet cable from PoE jack of the power supply for at least 10 seconds.

Reconnect the Ethernet cable to re-supply power to the ePMP device for 3-5 seconds and disconnect cable to power off the ePMP device for 3-5 seconds. (1st power cycle)

Reconnect the Ethernet cable to re-supply power to the ePMP device for 3-5 seconds and disconnect cable to power off the ePMP device for 3-5 seconds. (2nd power cycle)

Reconnect the Ethernet cable to re-supply power to the ePMP device for 3-5 seconds and disconnect cable to power off the ePMP device for 3-5 seconds. (3rd power cycle)

Reconnect the Ethernet cable to re-supply power to the ePMP device for 3-5 seconds and disconnect cable to power off the ePMP device for 3-5 seconds. (4th power cycle)

Reconnect the Ethernet cable to re-supply power to the ePMP device for at least 30 seconds and allow it to go through the boot up procedure (Note: Device will go through an additional reset automatically). This will reset the current configuration files to factory default configuration (e.g. IP addresses, Device mode, RF configuration etc.). The device can be pinged from a PC to check if boot up is complete (Successful ping replies indicates boot up is complete).

Access the ePMP device using the default IP address of 192.168.0.1 (AP) or 192.168.0.2 (SM).

" GNU GENERAL PUBLIC LICENSE Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble The licenses for most software are designed to take away your

freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
