ECN 7000 Series Hardware Guide 1 1 Introduction This chapter introduces the ECN 7000 Series of products, and describes the ECN hardware architecture.
2 Introduction Overview of the ECN 7000 Series Residential and commercial energy customers are increasingly focused energy efficiency and reliability, while also reducing the environmental impact of electricity use. National and regional power distribution grids in the 21st century must address these customer concerns, while at the same time monitoring electricity as it flows through many types of devices and transmission media (substation elements, high, medium, and low voltage power lines, capacitor banks, transformers, meters, communicating thermostats, load-control devices, and so on). A modern smart power grid network must be able to manage itself using intelligent distributed control and be able to communicate with any device, over any network or protocol, to optimize grid operations and anticipate problems before they occur. The Echelon Edge Control Node (ECN) 7000 Series of open and extensible hardware products enable power distribution grids to become smarter. The ECN 7000 Series distributes the intelligence that public and private electrical power utilities need to monitor and control devices at the edge of the grid. The edge of the grid is the critical point where the distribution network connects to customers and where energy supply and demand are becoming increasingly unpredictable and complex. The ECN 7000 Series of products use the Echelon Control Operating System (COS) software platform, which provides the open, secure and modular software framework needed to host hundreds of new applications needed for a smarter grid. This powerful combination of hardware and software brings intelligent distributed control to the edge of the grid for maximum reliability, survivability, and responsiveness. The ECN 7650 is the first member of the ECN 7000 Series of products. The ECN 7650 supports a variety of local, wide-area, and radio frequency (RF) networks, with up to nine antennas, all contained within the ECN 7650 enclosure to protect them from the weather and to reduce vandalism and security risks. An ECN 7650 device can accommodate a variety of expansion cards depending on form factor, power requirements, and communications technology. For example, you might design one card for RF communications and another for wired communications. Third-party vendors can develop ECN expansion cards for the following example applications: • Wide-area network (WAN) communications, for example for 2G, 3G, or 4G networks • Metering applications, such as 868 MHz or 900 MHz transceivers for gas, water, heat, and other metering and communications systems • Analog or digital I/O • Local device or network interfaces By combining an extensible hardware architecture with the COS software platform, the ECN 7000 Series of products provides 21st century management for the smart grid.
ECN 7000 Series Hardware Guide 3 The cover of the ECN 7650 is secured with one-way screws, which virtually eliminates unauthorized access. When the ECN 7650 is pad mounted, you secure the power and network connections inside a metal housing with a padlock. The ECN 7650 is also rugged and sturdy enough to allow a person (for example, a utility working gaffing a utility pole) to step on it. The ECN 7650 is designed for quick and secure installation using a rapid-mount bracket on either a utility pole or a pad-mounted distribution transformer. Because the ECN 7650 is small enough and light enough to hand carry, installation is simple and easy. ECN Hardware Architecture The ECN 7650 is a small, lightweight box that contains all of the hardware to support the COS software platform and third-party applications. The hardware architecture includes the following elements: • Main board • Measurement processor and internal sensors • Real-time clock • System cards • Expansion cards • Optional backup battery These hardware elements are housed in a rigid plastic enclosure that provides protection for the electronics. Figure 1 on page 4 shows a high-level view of the ECN architecture.

ECN Hardware Architecture The ECN main processor manages the other hardware components within the ECN and runs the COS system software and related applications. The main processor communicates with a measurement processor that monitors the overall health of the ECN unit, including internal sensors and certain input data. The measurement processor also provides a hardware watchdog function to ensure that the main processor remains responsive. The ECN main processor also communicates with system cards and expansion cards that provide the communications interfaces for the ECN. It is these cards that allow the ECN to communicate with smart meters, home area networks, wide area networks, and the Internet. Inside the ECN enclosure, all of the hardware is further enclosed in an inner card cage that protects the main processor, the system cards, and the expansion cards from exposure to the communications frequencies emitted from the antennas located at the periphery of the ECN unit. Figure 2 on page 5 shows the ECN with its external cover removed so that the inner card cage is visible. Also visible in the figure are the antenna holders at the edges of the enclosure.
ECN 7000 Series Hardware Guide 5 Figure 2. The ECN Inner Card Cage Figure 3 on page 6 shows the ECN removed from its enclosure and with the inner card cage removed. The figure highlights the locations of the expansion slots. Also visible are the ECN system slots and the main board. The antenna holders are more visible as well.
6 Introduction Figure 3. ECN Expansion Slots The expansion slots allow you to customize the functionality provided by the ECN to suit your application’s needs. Typically, an expansion card provides additional communications interfaces for the ECN, but it can also provide additional software applications to complement the COS system software. Main Board The ECN main board includes the power supply back end, USB hubs with power control, and high bandwidth interconnects for the system cards and expansion cards. There are six expansion slots available on the backplane, each allocated with its own backplane communications interface. See the Edge Control Node 7000 Series Expansion Card Developer’s Guide for more information about the expansion cards. You can access all expansion by removing the enclosure front cover and the inner card cage. The ECN system processor has four high bandwidth interfaces available for use by external peripherals: two USB hosts and two SPI ports for Ethernet connectivity. The SPI interfaces are only used for direct connectivity to Ethernet devices, but the USB interfaces are available on the backplane for the expansion slots. These system resources are optimized for high performance communications between devices with higher bandwidth requirements, such as EV-DO modems and Wi-Fi™ devices.
ECN 7000 Series Hardware Guide 7 Figure 4 shows the relationships between the main processor and the backplane. Some of the functionality is provided by system cards, and the rest is provided by expansion cards.

ECN Main Board Architecture Power Management The ECN main board includes the power supply for the ECN unit, as well as for the system cards and expansion cards. To maintain data integrity, the ECN includes several watchdog and reset functions. Main Power Supply The ECN power supply is capable of operating on any phase of a 3-wire 120/240 VAC or 120/208 VAC network, making it compatible with network and non-network transformers. The power can provide up to 30 W of continuous power, which is ideal for RF applications where low radiated emissions are critical. The main component of the power supply is located at the top of the ECN main board, where the Faraday cage can provide adequate ventilation to prevent excessive heating of the expansion cards. Power-Up Function On power-up, the ECN unit is held in reset by hardware watchdog circuitry until the power supply stabilizes at its operating threshold. This function provides a
8 Introduction soft-start mechanism for the ECN system processor and expansion cards, and prevents heavy loading on the power supply while line voltages are settling. When the power supply is stable, reset is released and a “wake-up” interrupt is issued to the measurement processor, which has been operating in watch mode while power was off. During initialization, the measurement processor starts to monitor the AC line voltage and begins its other measurement tasks. Power-Down Function While the ECN is operational, the measurement processor continually monitors line voltages. When the line voltage drops below 50% of nominal for longer than one minute, the system performs its power-down procedure: • The system processor completes housekeeping tasks. • If the ECN unit includes backup batteries, the ECN switches to battery power. • If the ECN unit does not include backup batteries, the main system processor and all expansion cards are held in reset and the measurement processor enters watch mode. In this mode, the real-time clock and tamper functions are maintained. For line voltage drops of less than one minute, the ECN operates in brown-out mode, with internal capacitance providing temporary power to the ECN unit. WARNING: Wait at least one minute after removing mains power from an ECN unit before opening the cover and handling internal components, including expansion cards. Brown-Out Function If the line voltage sags for longer than one second, but remains 50% to 80% of nominal, the ECN runs in a reduced state of operation known as brown-out. In this state, the ECN effectively operates as if it was in battery back-up mode, but power continues to be taken from the line voltage, not the battery. The measurement processor continues to monitor line voltage and hold the system in brown-out state until power is either restored or removed. Line voltage sags of less than one second are ignored and do not trigger a brown-out event. Energy Saving Mode The ECN also provides a “Burst Mode Control” option. When in burst mode, the power supply runs more efficiently. The burst mode circuit operates as a type of relaxation oscillator where the output voltage from the power supply switches between 11.8 VDC and 14.0 VDC. The burst mode operates when the temperature is greater than 60 °C, thereby reducing the power dissipation inside the ECN enclosure. Peripheral Power Control Power for the USB hubs and expansion cards is derived from the main power supply on the ECN main system board. The hubs are powered by a single +5 V
ECN 7000 Series Hardware Guide 9 convertor, whereas each expansion slot has its own convertor. Thus, the expansion cards can be designed to use a different voltage value, as needed. See the Edge Control Node 7000 Series Expansion Card Developer’s Guide for more information. The ECN main system processor can control power management for each of the USB hubs and expansion slots. When the main processor is held in reset (because of a watchdog or brown-out event), the expansion slots are automatically turned off. Software applications that run on the main processor can also control the USB power. For example, if a particular application senses a problem with a specific communications card, it can cycle power to that card to reset it. Alternatively, applications can turn off individual communications cards to reduce overall power consumption (for example, when the ECN is operating from battery back-up power). Watchdog and Reset The ECN includes a number of watchdog and reset functions: • System watchdog and reset (hardware only) • Measurement processor watchdog (software only) • Main system processor watchdog (software only) • Expansion card watchdog and power control (hardware and software) Figure 5 on page 10 shows the relationships between the various watchdog and reset functions. The following sections describe the functions.

Watchdog Functions System Watchdog and Reset A dedicated processor provides hardware watchdog functionality for the entire ECN system. The watchdog has master reset control over both the ECN main system processor and the measurement processor. The measurement processor maintains the watchdog with a 1.6 second refresh signal. If the measurement processor fails to provide this signal, the hardware watchdog automatically initiates a system reset. A system reset all processors, USB hubs, communications devices, and expansion cards to causes reinitialize. Measurement Processor Watchdog The ECN measurement processor runs a software process to maintain a software watchdog for the processor. If there is a malfunction of the measurement scheduler, the software watchdog initiates a reset or a power cycle of the processor, which causes a full system reset or power cycle for the ECN unit. System Processor Watchdog The ECN main system processor runs a process to maintain a software watchdog for the processor. If there is a malfunction, the software watchdog initiates a reset or a power cycle of the processor, which also causes all expansion cards to be reset or power cycled. Expansion Card Watchdog and Power Control The ECN main system processor has power control over all peripherals, including USB hubs and expansion slots. Applications running on the main system
ECN 7000 Series Hardware Guide 11 processor can monitor the health of each of the expansion cards through the USB interface. Internal Sensors The ECN includes internal sensors to detect removal of the external cover, change in the title angle of the unit, internal temperature, secondary voltage, and current. Enclosure Cover Removal Sensor The ECN includes a reed switch that is mounted in the enclosure cover for sensing removal of the enclosure cover. When the enclosure cover is removed, the measurement processor raises an alarm that you can monitor remotely. Cover switch sensing continues to operate when power is removed. Tilt Sensor The ECN includes a ball bearing tilt sensor that is mounted on the ECN main processor card for sensing changes in tilt angle of the unit. This sensor allows you to determine remotely if the ECN has fallen from or been removed from its pole or pad mounting. When the tilt angle exceeds 30º, the sensor triggers an alarm. The detection circuitry is monitored by the measurement processor after power is removed. The tilt sensor is available as a factory option. Temperature Sensor The ECN includes an internal temperature sensor that provides a linear output voltage proportional to local temperature, from –55 ºC to +130 ºC. This sensor is monitored directly by the measurement processor. Temperature measurements are used to compensate the real-time clock and power supply voltages. They can also be used to generate alarms in the event that the internal temperature approaches maximum permissible levels. If the internal temperature of the ECN enclosure exceeds the maximum operating limits (105 ºC), a protection circuit turns off the main power. This shutdown protects the electronics within the enclosure and also prevents the ECN from reaching unsafe temperature levels. Secondary Voltage Sensing The ECN power supply system card includes isolated voltage transformers that card are connected to the ECN line inputs. Each transformer provides a low voltage signal that is proportional to the line voltage, with signal amplitude of 5 Vp-p at 300 VAC. Voltages above and below the power supply rail limits are clamped by protection devices on the power supply card. The motherboard backplane connects the low voltage signals to the ECN power supply system card and the ECN main processor system card. The measurement
12 Introduction processor processes the signals in real time. If you connect secondary current transformers (CTs), the measurement processor can calculate VRMS and monitor power quality events (such as sag, swell, line frequency, harmonic content, and energy). The voltage measurement circuitry can be calibrated at the factory to provide increased accuracy. With calibration it is possible to achieve better than 2% accuracy for VRMS readings. The secondary voltage sensor is available as a factory option. Primary and Secondary Current Sensing You can connect the ECN main processor system card to up to three external current transformers or Rogowski coils. Because the type of sensor technology determines the signal conditioning circuitry needed, the analog conditioning circuit is located on an adaptor board that is fitted to the ECN processor system card. Thus, a change in this circuit does not require a new processor system card, but only the replacement of the conditioning circuit. The external sensors provide isolated voltages proportional to the current waveform to the ECN processor system card through connectors mounted in the ECN’s external connection panel. The sensor inputs can be connected to either the primary or secondary lines of the transformer. The typical supported current sensors provide either the standard 0.333 VAC full scale output or di/dt output. In the case of the 0.333 V standard, the signal conditioning circuit consists of three differential amplifiers. In the case of the Rogowski coils, it consists of three voltage integrators. The 0.333 V standard is supported by multiple vendors with clamp-on current transformers covering primary currents from 200 A to 2 kA. The di/dt sensors or Rogowski sensors are more flexible than CTs and are available in various forms that can be wrapped around awkwardly shaped bus bars. The signals from the conditioning circuit are fed to the measurement processor so that IRMS can be calculated in real time. If the current sensors are on the secondary of the transformer, then IRMS and VRMS measurements can be combined to calculate total power, reactive energy, and active energy. The current measurement circuitry can be calibrated at the factory to provide increased accuracy. With calibration it is possible to achieve better than 2% accuracy for IRMS readings. Real-Time Clock The ECN measurement processor provides real-time clock function for the ECN unit. The real-time clock is accurate to at least +/- 6 ppm (6 µs drift). This tight accuracy is achieved by calibrating the clock during manufacturing. The ECN measurement processor adjusts the real-time clock, as needed, based on internal temperature measurements to maintain clock accuracy over the operating temperature range of the ECN. The COS system software can also adjust the real-time clock in the field, as needed. When mains power is removed from ECN, the measurement processor switches to battery backup power to maintain the real-time clock. In this mode, the
ECN 7000 Series Hardware Guide 13 processor is powered from a non-replaceable 3 VDC lithium battery located on the processor card. Tamper functions are also maintained during this period. This battery provides at least 10 years of functionality for the real-time clock. If you plan to store the ECN for significant periods of time, the measurement processor can be placed in stop mode to further extend the effective life (up to 20 years). When power is first applied to an ECN in this state, the COS system software enables watch mode and updates the date and time. When mains power is restored, the real-time clock time and date registers are updated along with the tamper status. Communications Interfaces The ECN supports many communications interfaces. Some, such as power line communications, are supported by system cards that are included with the ECN or are available as orderable options. Others, such as wireless modems, are supported by expansion cards provided by third-party manufacturers. This section describes the many communications interfaces supported by the ECN. Some communications interfaces are available as factory options, as shown in Figure 6 on page 14. In the figure, options are shown with dashed lines. The following sections describe each of the communications interfaces available for the ECN.

RF Communications Options for the ECN Power Line Communications Two of the ECN system cards provide support for Echelon’s Power Line technology within the communications frequencies defined by the comité européen de normalization electrotechnique1 (CENELEC) EN 50065-1 media access protocol standard. One card supports the CENELEC A Band (3 kHz to 95 kHz) and the other card supports the CENELEC C Band (125 kHz to 140 kHz). The A Band is typically restricted to electricity suppliers and their licensees; it is also used by Echelon’s NES System, the advanced metering infrastructure (AMI) 1 European Committee for Electrotechnical Standardization
ECN 7000 Series Hardware Guide 15 within the COS software platform. The C Band is typically used for commercial and residential applications, such as those that use LONWORKS communications channels. Each Power Line Communications card contains the following components: • An Echelon PL 3120® Power Line Smart Transceiver, configured for communications within the A Band or the C Band • Appropriate Power Line coupling circuit • Voltage transformer for secondary line-voltage monitoring • Zero-crossing detector • High-voltage rectifiers with surge protection • A USB Hub and associated USB-to-serial converter for communicating with the ECN main system processor The following features of the Echelon PL 3120 Power Line Smart Transceiver provide high performance communications over power lines: • Unique dual-carrier frequency feature, which automatically selects an alternate secondary communications frequency if the primary frequency is blocked by noise. • Highly efficient, patented, low-overhead forward error correction algorithm to overcome errors induced by noise. • Sophisticated algorithms for digital signal processing, noise cancellation, and distortion correction. These features correct for a wide variety of signaling impediments, including impulsive noise, continuous-tone noise, and phase distortion. A Power Line Smart Transceiver requires an isolated coupling circuit tuned to its specific transmission frequencies to be able to inject its signal into the low impedance power cables. The power amplifiers are capable of delivering a 10 Vp-p (2 Ap-p) signal into the power lines. The coupling circuits are specially tuned transformers that provide isolation between the high-voltage power lines and the low-voltage Power Line Smart Transceiver. Whenever line voltage is removed from the ECN, the main system processor holds the Smart Transceivers in reset or powers them off. See Power Management on page 7. Ethernet The ECN main system board provides two Media Access Control (MAC) physical layer (PHY) ports that provide support for the IEEE 802.3 standards for Ethernet-over-twisted-pair networking. The Ethernet 10/100 interfaces support two different speeds of Ethernet on the same port: 10BASE-T (10 Mbit/s) and 100BASE-TX (100 Mbit/s). The Ethernet MAC PHYs are connected to the SPI ports of the main system processor.
16 Introduction The ECN external connection panel includes two 8 Position 8 Contact (8P8C; also known as RJ45) modular connectors for connecting to the Ethernet network. You can use standard ANSI/TIA/EIA-568-A Category 5 cable in either the T568A or T568B wiring configuration. These Ethernet connectors have built-in transformers on the ECN main system board. The external connector is included with the External Connections + Serial option. Wi-Fi The ECN can include a Wi-Fi access point that supports simultaneous dual-band Wi-Fi clients. An option is also available that supports the draft IEEE 802.11s Wi-Fi meshing standard. EV-DO The ECN can include an Evolution-Data Optimized (EV-DO) modem that conforms to the TIA-856 Rev. B standard. For US models, the modem has been certified through the Verizon Wireless™ Open Development program to operate with the Verizon Wireless 3G network. Thus, the ECN can provide broadband Internet access to devices at the edge of the Smart Grid. USB The ECN main system board includes two Universal Serial Bus (USB) host controllers. These hosts allow connectivity to the three USB hubs that are included on the ECN main processor system card and to the six expansion slots. The USB hosts support the USB 1.1 specification at either 1.5 Mbit/s (Low-Bandwidth) or 12 Mbit/s (Full-Bandwidth). All expansion slots support a USB power interconnect (+1.8 VDC to +12 VDC variable-voltage input determined by the expansion card) and USB data interconnect. Serial The ECN can include serial communications connectors that provide serial ports for communicating with serial devices. The serial ports use standard 5-wire EIA-232 interface with a standard 9-pin female DE-9 connectors. There is also an optional Distributed Network Protocol (DNP3) driver available for process automation and distribution automation systems. The serial connections are included with the External Connections + Serial option. Multi-Utility Meters The ECN expansion slots support several wired and wireless technologies that allow the ECN to monitor advanced multi-utility meters, such as water and gas meters. Thus, the ECN can gather information about many forms of energy and power being used at the edge of the Smart Grid. For example, you can install an expansion card with a modem to connect to a Badger® Meter ORION® system or
ECN 7000 Series Hardware Guide 17 an Itron® Energy Gateway with an Itron Encoder-Receiver-Transmitter (ERT®) module. The end points for such multi-utility meters typically transmit their register readings periodically (for example, every 8 seconds for a Badger meter), so the reader must be able to capture these readings and transmit them to the ECN, which forwards the information to the back end software. Digital The ECN external connection panel includes a digital input connector that connects the measurement processor to external devices. The measurement processor monitors changes in state of the input, and raises an alarm for state changes. You can monitor the alarms remotely. GPS The ECN has a built-in Global Positioning System (GPS) modem operating at 1575.42 MHz. The GPS antenna is an active 12-channel antenna, mounted near expansion slot 5 in the outer plastic enclosure. Antenna Support EV-DO modems operating in the 800 MHz and 1900 MHz bands, or modems that operate within 900 MHz industrial, scientific and medical (ISM) radio bands, typically require two dual-band antennas for diversity operation. If both antennas are mounted with the same polarization, the antennas must be separated by approximately 16.5 cm (6.5 in). However, if one antenna is mounted vertically and the other antenna is mounted horizontally (that is, they have polarization diversity), the two antennas can be located in close proximity to one another. The antenna for an EV-DO or ISM radio system is a ½ wave length antenna that does not require a ground plane or counterpoise. Thus, the antenna is approximately 12 cm (5 in) in length. The antennas are mounted in the outer plastic enclosure and connect directly to the expansion card using coax cable. Expansion Card Architecture An ECN device can accommodate a variety of expansion cards depending on form factor, power requirements, and communications technology. Because each application has different requirements for its expansion card, the ECN provides six expansion slots, each of which can support one or more types of expansion card. All expansion slots support a USB power interconnect (+1.8 VDC to +12 VDC variable-voltage input determined by the expansion card) and USB data interconnect. Expansion slot 6 also provides an Ethernet connection. See the Edge Control Node 7000 Series Expansion Card Developer’s Guide for more information about the requirements for each expansion card type. The guide also describes the requirements for each device’s antennas.
18 Introduction Backup Battery To provide power to the ECN unit during extended power outages, the ECN can optionally be fitted with a backup battery. The ECN enclosure includes a separate compartment for the battery module. Within this compartment, a blind-mate electrical connector allows easy installation for the battery module. This separate compartment is weather tight and provides shielding from sensitive electronics and radios. Figure 7 shows the battery pack, after it is removed from the ECN. The ECN uses intelligent battery charging techniques (similar to those found in laptop computers) to maximize the life of the battery. That is, the ECN constantly monitors the state of the Lithium Ion cells used in the module to ensure long life and reliable operation. A typical charge cycle can take up to 4 hours. Each battery pack has an operating life of approximately 10 years. Figure 7. Battery Pack The battery module is capable of providing up to 24 W of power for at least 15 minutes. Table 2.

ECN 7000 Series Hardware Guide 19 2 Installing Components and Troubleshooting This chapter describes how to install components in an ECN unit before field deployment and how to perform basic troubleshooting for a unit returned from the field.
20 Installing Components and Troubleshooting Installing Components Because the ECN’s cover is not designed to be removed in the field (the cover is secured with one-way screws), you generally cannot perform in-field service for an ECN. If an ECN becomes non-operational, you should replace it in the field with a similarly equipped model to maintain operational service for your customers; see Chapter 5, Field Replacement for an ECN 7000 Series Device, on page 49. You can return the non-operational ECN to your service center for maintenance. The following sections describe how to install components in an ECN unit before field deployment. Removing the Cover The cover is secured to the ECN enclosure with four #10 (M5) one-way screws to prevent their unauthorized removal in the field. To remove these screws, use a one-way screw removal tool, which are available from vendors such as W.W. Grainger®, Inc. or Hudson Fasteners, Inc. Important: Removing the cover compromises the factory seal. You must replace the gasket and sealing screws to reestablish a proper seal. To remove the cover, remove the screws at the four corners of the ECN enclosure, as shown in Figure 8. Figure 8. Top View of ECN with Cover Attached Removing the Card Cage The card cage is secured to the interior of the ECN enclosure with four #10 (M5) standard Phillips® screws.
ECN 7000 Series Hardware Guide 21 To remove the card cage, remove the screws at the four corners of the card cage, as shown in Figure 9. Figure 9. Top View of ECN with Cover Removed Removing RF Shields Prior to installing an expansion card in expansion slots 3, 4, or 5, you must remove the factory-installed RF shielding for these slots. This shielding protects the rest of the ECN electronics from unintended emissions from the wireless or cellular modems installed in these slots. Figure 10 on page 22 shows these slots with and without their RF shielding.
22 Installing Components and Troubleshooting Figure 10. RF Shielding for Expansion Slots 3, 4, and 5 Installing an Expansion Card The ECN main board includes two types of slots: system slots and expansion slots. System slots contain system cards that are installed in the factory and provide basic or pre-installed optional functionality for the ECN. Expansion slots contain expansion cards that are generally installed before field deployment (although some expansion cards can be factory installed) and provide additional functionality for the ECN. For example, an expansion card can add a modem for additional communications functionality. There are six expansion slots (numbered 1 to 6), and five types of expansion card, types A, B, C, D, and E. Each of these types has different electrical and mechanical characteristics based on the type of functionality it is designed to provide. See the Edge Control Node 7000 Series Expansion Card Developer’s Guide for more information about each of the card types. Important: The ECN hardware, operating system, and communications software does not support plug and play or hot plug of expansion cards. Power must be removed from the ECN before installing, or uninstalling, an expansion card. Installation for Card Types A and B Access to expansion slots 1 and 2 can be made while the card cage is installed in the outer enclosure: 1. Remove the enclosure cover 2. Remove the inner card cage cover 3. Remove the card retainer Card guides are made available for each slot, which (along with the alignment holes in the ECN main board) prevent expansion cards from being misaligned on
ECN 7000 Series Hardware Guide 23 installation. After a card is installed, you must screw the card retainer back in place to prevent the card from becoming dislodged during transportation. If the expansion card requires electrical connections to external devices, those electrical connections must be positioned as close as possible to the edge of the card facing the external connection plate. Connection between the card and the IP66 connector on the ECN external connection panel must use a short cable. Installation for Card Type C Access to expansion slots 3 and 4 can be made while the card cage is installed in the outer enclosure: 1. Remove the enclosure cover 2. Remove the inner card cage cover 3. Remove the individual RF shields Card guides are made available for each slot, which (along with the alignment holes in the ECN main board) prevent expansion cards from being misaligned on installation. After a card is installed, you must reinstall the RF shielding. Make antenna connections using a suitable coaxial cable, and exit the shielding as recommended. Routing for antenna cables must follow the requirements described in your compliance approvals. The antennas must be installed as directed using the mounting points provided. Installation for Card Type D Access to expansion slot 5 can be made while the card cage is installed in the outer enclosure: 1. Remove the enclosure cover 2. Remove the inner card cage cover 3. Remove the RF shield that protects the slot Mount the card to the four PCB standoffs located inside the shielded enclosure using four retaining screws. You must provide an interface for the card that is compatible with expansion slot 5’s mechanical and electrical requirements. You can install multiple cards at this location. Make antenna connections using a suitable coaxial cable, and exit the shielding as recommended. Routing for antenna cables must follow the requirements described in your compliance approvals. The antennas must be installed as directed using the mounting points provided. Installation for Card Type E Access to expansion slot 6 can only be made when the inner card cage is removed from the outer enclosure. Gain access to the slot by removing the slot cover plate. Mount the card using five PCB standoffs that you screw to the cover plate. Reinstall the cover plate and card into the card cage as a single assembly. You must provide an interface for the card that is compatible with expansion slot 6’s mechanical and electrical requirements. You can install multiple cards at this location.
24 Installing Components and Troubleshooting Make antenna connections using a suitable coaxial cable, and exit the shielding as recommended. Routing for antenna cables must follow the requirements described in your compliance approvals. The antennas must be installed as directed using the mounting points provided. Installing an Antenna You can use the internal antenna holders for your own PCB antennas. Figure 11 shows the various antenna holders attached to the ECN inner card cage. The holders are extremely flexible and allow antennas of various sizes to be mounted on multiple planes. Recommendations: • Use the holders along each side for EV-DO, GPRS and ISM type applications. In particular one holder can be used on each side for diversity. • Use the holders along the top of the card cage for Wi-Fi and Wi-Max applications. The holders also have built in clips that can be used for locating cabling and holding protective ferrite beads. Figure 11. Antenna Holder Locations
ECN 7000 Series Hardware Guide 25 Troubleshooting The ECN is designed to perform without malfunctioning for a period of at least 10 years in harsh environmental conditions. In addition, the ECN outer enclosure is designed to provide IP66 protection, as defined by International Electrotechnical Commission (IEC) standard 60529. All Echelon supplied connectors are IP67 rated, and each connector has a cap designed to maintain its long-term reliability. The main symptom of a problem with an ECN unit would be a communications problem on one or more of the communications channels. You perform different troubleshooting tasks, depending on whether the unit is already field installed or is not yet deployed. For field-installed units, you can perform the following tasks to troubleshoot communications problems: • Verify that the cables are correctly plugged into their connectors on the ECN bottom panel. Check that the lock nut for each connector is secure. As necessary, ensure that no pins on any of the connectors are bent or damaged. • Attempt to communicate with the ECN unit with the COS system software. If possible, reboot the unit. • If you cannot connect to the ECN unit from the COS system software, remove power from the unit, wait at least two minutes, and reconnect power. Verify that the unit is operational, as described in Verifying Successful Installation on page 33. • If you still cannot establish communications, replace the unit, as described in Chapter 5, Field Replacement for an ECN 7000 Series Device, on page 49. Return the failed unit to your deployment station, or contact Echelon Support for service. For units not yet deployed, you can perform the following tasks to troubleshoot communications problems: • Perform the same set of tasks described above for field-installed ECN units. • Ensure that power is not connected to the unit. Remove the ECN cover, as described in Removing the Cover on page 20. Look for any obvious problems. Ensure that each antenna (if any) is seated correctly, and that any connector cables for the antennas are secure. • Remove the card cage, as described in Removing the Card Cage on page 20. Look for any obvious problems. Ensure that each card, both system and expansion, is seated correctly. Ensure that any connector cables are secure. • Connect power to the ECN unit, and attempt to reestablish communications. Be sure to follow proper safety protocols when supplying power with the cover removed. • If you still cannot establish communications, contact Echelon Support for service.
26 Installing Components and Troubleshooting
ECN 7000 Series Hardware Guide 27 3 Pole Mount Installation This chapter describes how to install the ECN on a utility pole.
28 Pole Mount Installation Introduction You can install an ECN on any standard utility pole, in either the supply space or the common area. The ECN provides a carrying loop for a carabiner hook to allow you to easily carry the ECN while climbing the pole. The ECN is also small and light enough that you can carry it while working from a boom lift. After installation, the ECN can withstand a 115 kg (250 lb) load, for example, of a utility worker stepping on the unit. The ECN is designed to be small enough that a utility worker can gaff up the pole and around the unit with minimal difficulty. The installation includes a bracket that you attach to the utility pole. You then attach the ECN to the installed bracket. Subsequent replacement or installation of an ECN can reuse the installed bracket, thus substantially reducing replacement installation time and effort. In addition, you can connect or disconnect the ECN from either power or the communications network easily, without having to uninstall the entire unit. Required Tools To perform the installation for the Pole Mounting Bracket, you will need the following tools: • Support bolt: 12 to 70 cm (4.5 to 27.5 inches) in length (depends on the pole class and the planned installation height for the ECN), 1.6 cm (5/8 inch) in diameter • One or two 1.6 cm (5/8 inch) washers, combined thickness 5.72 cm (2-1/4 inch) • One 1.6 cm (5/8 inch) square-head or hex-head nut • A drill, with drill bit appropriate for a 1.6 cm (5/8 inch) diameter bolt that is 12 to 70 cm (4.5 to 27.5 inches) in length • A wrench suitable for 1.6 cm (5/8 inch) bolts • A wire stripping tool • A fiberglass or plastic cable puller tool • A standard Phillips® screwdriver, Point Size 2 In addition to the tools listed above, you need an ECN Pole Mount Kit and the appropriate ECN input power cable accessory: • The input power cable accessory is available in three lengths: 3 m, 9 m, and 12 m (10 ft, 30 ft, and 40 ft). • The cable type conforms to the specifications for 1.29 mm (16 AWG) stranded copper conductors. The outer jacket for the cable is insulated (600 V rating). The cable includes four conductors: o Black: Phase 1 o Blue: Phase 2 o Red: Phase 3
ECN 7000 Series Hardware Guide 29 o White: Neutral The ECN does not use the blue connector (phase 2). • The end of the cable that connects to the ECN input power connector is fitted. The other end of the cable is not fitted. Installation Location Typically, you install the ECN on a utility pole either in the supply space (near the service distribution transformer) or in the common area (3-½ to 4-½ meters or 12 to 15 feet above ground level). Important: Do not install the ECN in the communication space; that space is reserved for cable, telephone, and other companies to install their equipment. For optimal antenna performance, you should place the ECN as high on the utility pole as possible, in the supply space. However, many installations will install the ECN common area: installation in the common area is typically easier to perform, less expensive, and involves less risk for the installer. Preparing for Installation After you have selected the installation location on the utility pole (within the supply space or in the common area), determine the distance from the low-voltage (LV) attachment point (typically at or near the service distribution transformer) and the proposed installation point for the ECN. If the ECN input power cable is shorter than this distance, splice an additional length of cable and weather seal that splice. When the ECN is installed in the common area, the input power cable must be shielded in a protective conduit to protect the input power cable from communications workers and other personnel who climb the pole. When the ECN is installed in the supply space, this protective conduit is not necessary. You can use a simple vertical wire guard, but generally you should use Schedule 40 conduit.2 Leave both the top and bottom of the conduit open so that water can flow freely through the conduit. The bottom end of the conduit should terminate near the ECN, but should not be attached to it. Feed the input power cable through the conduit and connect it to an available power source. Drill a hole through the utility pole. The diameter of this hole should be able to fit a 1.6 cm (5/8 inch) diameter bolt securely. The hole should be centered horizontally with respect to the pole diameter, and should be centered vertically with respect to the planned location of the ECN. Performing the Installation To install the ECN using the pole mount method, perform the following tasks: 1. Attach the Pole Mounting Bracket to the pole 2. Attach the ECN to the Pole Mounting Bracket 3. Secure the ECN to the Pole Mounting Bracket 2 See UL 651, NEMA TC-2, or NEC-Article 352 for Schedule 40 specifications.
30 Pole Mount Installation 4. Connect the ECN to power and to the network 5. Complete the installation Each of these tasks is described in the following sections. Attach Pole Mounting Bracket You connect the ECN to the utility pole using the hole that you drilled into the pole to prepare for installation; see Preparing for Installation on page 29. Place the bracket against the pole, insert the support bolt, and secure the bolt with a washer and nut, as shown in Figure 12. The Pole Mounting Bracket is designed to fit any standard utility pole. Figure 12. Attach Pole Mounting Bracket Attach ECN to Pole Mounting Bracket After the Pole Mounting Bracket is securely attached to the utility pole, you can attach the ECN to the Pole Mounting Bracket. The top of the back side of the ECN includes two tabs that slide into the top of the Pole Mounting Bracket. Figure 13 on page 31 shows the ECN attached to the Pole Mounting Bracket. Note that if you should need to replace an ECN, you need replace only the ECN and not the Pole Mounting Bracket.
ECN 7000 Series Hardware Guide 31 Figure 13. Attach the ECN to the Pole Mounting Bracket Secure ECN to Pole Mounting Bracket To secure the ECN to the Pole Mounting Bracket, secure the two captive ¼-20 screws to the bottom of the ECN to attach it to the Pole Mounting Bracket. These screws are already connected to the ECN, and are designed not to make contact with the pole. Figure 14 on page 32 shows a front view of the ECN attached to the Pole Mounting Bracket, with the bottom screws visible.
32 Pole Mount Installation Figure 14. Secure the ECN to the Pole Mounting Bracket Connect the ECN to Power and the Network You make the connections to power and to the communications network at the bottom of the ECN. All Echelon supplied connectors are IP67 rated. Each connector has a cap designed to maintain its long-term reliability. Figure 15 on page 33 shows the bottom of a typical ECN, before installation. You can connect the ECN to either low voltage, or with the CT option, medium voltage. The exact configuration of the ECN bottom panel depends on the options that you have installed in the ECN, but at a minimum, the bottom panel has a connection for power. In the figure, the upper left connection is for power. To make the power connection, remove the cap, insert the power cable, and twist the cable ¼ turn to lock it in place.
ECN 7000 Series Hardware Guide 33 Figure 15. Connect the ECN to Power and the Network Complete the Installation After the installation is complete, perform the following tasks: 1. Inspect the connection of the ECN to the Pole Mounting Bracket. 2. Inspect the connection of the Pole Mounting Bracket to the utility pole. 3. Inspect the cabling connections to the ECN. The completed installation should look similar to the views depicted in Figure 13 on page 31. Note that the figure does not show the cabling connections to the ECN. Verifying Successful Installation Because the ECN has no external lights or displays, it uses an internal audio buzzer to provide indications of important installation-related states. The buzzer’s audio frequency is 2.4 kHz (as a 1/2 duty cycle square wave) and outputs 85 to 92 dBA of sound pressure,3 which should be audible from at least 10 m (30 ft). Table 3 on page 34 lists the sound patterns for the audio indicator. The audio indicator outputs its audio indicator patterns only during ECN startup. 3 dBA measures sound pressure levels relative to 20 µPa (rms) at 1 m.
34 Pole Mount Installation Table 3. Internal Audio Indicator Sound Patterns Sound Pattern Description On (ms) Off (ms) Repeat 1000 0 1 ECN boot process successful System Manager is now running 4000 0 1 ECN boot process failed 1000 500 2 WAN connection to cell tower successful 4000 200 2 WAN connection to cell tower failed 1000 500 3 Connection to System Software successfully established 4000 200 3 Connection to System Software failed As the table shows, a successful installation should include several 1 second sound bursts, some with a repeated pattern (1 s on, 0.5 s off) to indicate successful network connections. If you receive a 4 s sound burst, the ECN boot process failed. If you receive the repeated pattern (4 s on, 0.2 s off), a network connection failed; check the network cable connection and verify that the network is operational. After installation is verified successful, use the COS Web page interface for the ECN to verify additional functionality. You might also want use the command-line interface to disable the internal audio indicator so that subsequent resets or power events do not cause the audio indicator to output its audio indicator patterns. You can also change the audio indicator patterns by modifying the controller configurable file (CCF); see the COS User’s Guide for information about modifying the audio indicator patterns.
ECN 7000 Series Hardware Guide 35 4 Pad Mount Installation This chapter describes how to install the ECN on a service distribution transformer that is mounted on a transformer pad.
36 Pad Mount Installation Introduction You can install an ECN on the same transformer pad as a service distribution transformer, and secure it to the transformer without drilling holes into or otherwise damaging the transformer housing. After installation, the ECN is resistant to manual removal, and none of the electrical or communications network connections can be accessed by unauthorized personnel. The installation includes a bracket that you attach to the transformer housing and transformer pad. You then attach the ECN to the installed bracket. Subsequent replacement or installation of an ECN can reuse the installed bracket, thus substantially reducing replacement installation time and effort. In addition, you can connect or disconnect the ECN from either power or the communications network easily, without having to uninstall the entire unit. Required Tools To perform the installation for the Pad Mounting Bracket, you will need the following tools: • Connection bolt: 5 cm (2 inches) in length, 1.6 cm (5/8 inch) in diameter • A 1.6 cm (5/8 inch) washer • Two 1.6 cm (5/8 inch) concrete-compatible bolt kits • Conduit housing • A wrench suitable for 1.6 cm (5/8 inch) bolts • A wire stripping tool • A fiberglass or plastic cable puller tool • A standard Phillips screwdriver, Point Size 2 • A shovel (hand or power) or similar digging tool • Standard conduit sealing putty or foam In addition to the tools listed above, you need an ECN Pad Mount Kit and the appropriate ECN input power cable accessory: • The input power cable accessory is available in three lengths: 3 m, 9 m, and 12 m (10 ft, 30 ft, and 40 ft). • The cable type conforms to the specifications for 1.29 mm (16 AWG) stranded copper conductors. The outer jacket for the cable is insulated (600 V rating). The cable includes four conductors: o Black: Phase 1 o Blue: Phase 2 o Red: Phase 3 o White: Neutral The ECN does not use the blue connector (phase 2). • The end of the cable that connects to the ECN input power connector is fitted. The other end of the cable is not fitted.
ECN 7000 Series Hardware Guide 37 Installation Location For optimal antenna performance, you should place the ECN as high on the distribution transformer as possible. However, most installations will require that the top of the ECN after installation extend no higher than the top of the transformer. A typical residential transformer measures between 46 cm (18 inches) and 74 cm (29 inches) in height. If you place the ECN exactly even with the top of the transformer, you have between 15 cm (6 inches) and 43 cm (17 inches) clearance from the transformer pad to the bottom of the ECN. For most installations, this clearance is sufficient to connect the installed ECN to external power and the communication network. Installation rules also typically require that the top of the 1.9 cm or 3.2 cm (¾” or 1-1/4”) flexible conduit should be at least 7.6 cm (3 inches) above grade level to prevent water ingress into the conduit. That is, there must be at least 7.6 cm (3 inches) of clearance from the bottom locking nut on the outside of the 1.9 cm or 3.2 cm (¾” or 1-1/4”) flexible conduit. Preparing the Transformer Pad To prepare to connect the ECN to the power mains at the transformer, perform the following tasks: 1. Open the transformer cover to determine the location of an unused pre-cored hole in the transformer pad. This hole must be large enough to accommodate the 1.9 cm or 3.2 cm (¾” or 1-1/4”) flexible conduit for the ECN. 2. Use a shovel or similar tool to dig under the transformer pad to clear space for the conduit. 3. Fit the conduit up and into the hole. 4. Position the conduit as near to the lifting nut on the side of the transformer as possible. Ideally, the conduit should be positioned vertically under the lifting nut. 5. Cut to the conduit to the approved length. 6. Replace the dirt below the transformer pad. 7. Close the transformer cover. Preparing for Installation After you prepare the transformer pad, you can complete installation preparation by performing the following steps: 1. Use a cable stripping tool to strip approximately 45 cm (18 inches) of the insulating jacket from the conductors of the non-fitted end of the power cable. 2. Use a fiberglass or plastic cable puller tool to thread the power cable though the conduit that you prepared in the previous section, Preparing the Transformer Pad. 3. On the transformer side, attach the cables to the transformer so that they can provide power to the ECN.
38 Pad Mount Installation 4. Seal the top of the conduit inside the transformer cover with sealing putty or foam. This seal ensures that water and foreign objects cannot enter the transformer housing. 5. Seal the end of the conduit that is external to the transformer cover with sealing putty or foam. After the conduit and cabling are ready, you can install the ECN. See the next section, Performing the Installation. Performing the Installation To install the ECN using the pad mount method, perform the following tasks: 1. Extend the Pad Mounting Bracket 2. Attach the Pad Mounting Bracket to the transformer’s lifting nut 3. Attach the Conduit Housing to the Pad Mounting Bracket 4. Insert a Conduit Thread into the Conduit Housing 5. Attach the ECN to the Pad Mounting Bracket 6. Secure the ECN to the Pad Mounting Bracket 7. Connect the ECN to power and to the network 8. Close and lock the Conduit Housing 9. Complete the installation Each of these tasks is described in the following sections. Extend Pad Mounting Bracket You connect the ECN to the transformer using the transformer’s lifting nut, as described in Attach Pad Mounting Bracket to Lifting Nut on page 39. The Pad Mounting Bracket is designed to secure the ECN to the transformer’s lifting nut, regardless of the location of the lifting nut. The Pad Mounting Bracket is vertically adjustable (from approximately 46 cm [18 inches] to 92 cm [36 inches]) so that you can match the 1.9 cm (3/4 inch) horizontal slots with the position of the transformer lifting nut. Figure 16 on page 39 shows the Pad Mounting Bracket fully extended.
ECN 7000 Series Hardware Guide 39 Figure 16. Extend the Pad Mounting Bracket Attach Pad Mounting Bracket to Lifting Nut Because it is generally inadvisable to drill holes into the transformer housing, you use one of the 1.6 cm (5/8 inch) welded lifting nuts (inside the transformer cabinet and exposed through a hole in the transformer casing) as the installation point. Locate one of the transformer’s lifting nuts. There is no standard for the location of the lifting nuts, but typically one is within a few centimeters (an inch or two) of the top of the transformer. Measure the distance from the lifting nut to the top of the transformer, and extend the Pad Mounting Bracket to ensure that after the bracket is attached to the lifting nut, the top of the bracket is as close to the top of the transformer as possible. To secure the ECN to the transformer’s lifting nut, temporarily remove the nut. Position the Pad Mounting Bracket so that one of the horizontal slots matches the position of the lifting nut. Attach the Pad Mounting Bracket to the lifting nut. Figure 17 on page 40 shows the Pad Mounting Bracket attached to the lifting nut. After you secure the Pad Mounting Bracket to the lifting nut, secure the bracket to the transformer pad using the two 1.6 mm (5/8 inch) slots at the bottom of the bracket.
40 Pad Mount Installation Figure 17. Attach the Mounting Bracket to the Transformer’s Lifting Nut Attach Conduit Housing to Pad Mounting Bracket To protect the electrical and network connections to the ECN, the Pad Mounting Bracket includes a Conduit Housing. The Conduit Housing is approximately 13 cm (5 inches) high and 30 cm (12 inches) wide. Attach the Conduit Housing to the bottom of the upper extension of the Pad Mounting Bracket, as shown in Figure 18 on page 41. You can perform this step prior to field installation.
ECN 7000 Series Hardware Guide 41 Figure 18. Attach the Conduit Housing to the Pad Mounting Bracket Insert Conduit Thread into Conduit Housing To protect the electrical and network cabling as it enters the Pad Mounting Bracket Conduit Housing, insert a Conduit Thread unit into one of the available holes in the bottom of the Conduit Housing. The Conduit Thread should accommodate the locking nut for the conduit and the radius of one or more cable bundles. The Conduit Housing provides three cutouts for conduits; at least one of these should be precut to allow for insertion of the electrical and network cabling. Insert the Conduit Thread into the Conduit Housing, as shown in Figure 19 on page 42. You can perform this step prior to field installation.
42 Pad Mount Installation Figure 19. Insert a Conduit Thread into the Conduit Housing Attach ECN to Pad Mounting Bracket After the Pad Mounting Bracket is securely attached to the transformer, and the Conduit Housing is securely in place, you can attach the ECN to the Pad Mounting Bracket. The top of the back side of the ECN includes two tabs that slide into the top of the Pad Mounting Bracket. Figure 20 on page 43 shows the ECN attached to the Pad Mounting Bracket. Note that if you should need to replace an ECN, you need replace only the ECN and not the Pad Mounting Bracket.
ECN 7000 Series Hardware Guide 43 Figure 20. Attach the ECN to the Pad Mounting Bracket Secure ECN to Pad Mounting Bracket To secure the ECN to the Pad Mounting Bracket, secure the two captive ¼-20 screws to the bottom of the ECN to attach it to the Pad Mounting Bracket. These screws are designed not to make contact with the transformer. Figure 21 on page 44 shows a front view of the ECN attached to the Pad Mounting Bracket, with the bottom screws visible.
44 Pad Mount Installation Figure 21. Secure the ECN to the Pad Mounting Bracket Connect the ECN to Power and the Network You make the connections to power and to the communications network at the bottom of the ECN, which is inside the Conduit Housing. All Echelon supplied connectors are IP67 rated. Each connector has a cap designed to maintain its long-term reliability. Figure 22 on page 45 shows the bottom of a typical ECN, before installation. You can connect the ECN to either low voltage, or with the CT option, medium voltage. The exact configuration of the ECN bottom panel depends on the options that you have installed in the ECN, but at a minimum, the bottom panel has a connection for power. In the figure, the upper left connection is for power.
ECN 7000 Series Hardware Guide 45 To make the power connection, remove the cap, insert the power cable, and twist the cable ¼ turn to lock it in place. Figure 22. Connect the ECN to Power and the Network Because the transformer’s lifting nut is not necessarily centered vertically with where you placed the 1.9 cm or 3.2 cm (¾” or 1-1/4”) flexible conduit relative to the transformer pad, ensure that the flexible conduit is long enough to reach both the Conduit Housing and the connections on the ECN. Close and Lock the Conduit Housing After you have completed all cabling connections and are ready to complete ECN installation, close the Conduit Housing door and secure it with a lock, as shown in Figure 23 on page 46. The Conduit Housing includes a 1.3 cm (½ inch) hasp hole for the lock.
46 Pad Mount Installation Figure 23. Close and Lock the Conduit Housing Complete the Installation After the installation is complete, perform the following tasks: 1. Inspect the connection of the ECN to the Pad Mounting Bracket. 2. Inspect the connection of the Pad Mounting Bracket to the transformer. 3. Inspect the cabling connections to the ECN. 4. Inspect the transformer pad. The completed installation should look similar to the views depicted in Figure 24 and Figure 25 on page 47. Note that the figures do not show the cabling connections to the ECN.

48 Pad Mount Installation Verifying Successful Installation Because the ECN has no external lights or displays, it uses an internal audio buzzer to provide indications of important installation-related states. The buzzer’s audio frequency is 2.4 kHz (as a 1/2 duty cycle square wave) and outputs 85 to 92 dBA of sound pressure,4 which should be audible from at least 10 m (30 ft). Table 4 lists the sound patterns for the audio indicator. The audio indicator outputs its audio indicator patterns only during ECN startup. Table 4. Internal Audio Indicator Sound Patterns Sound Pattern Description On (ms) Off (ms) Repeat 1000 0 1 ECN boot process successful System Manager is now running 4000 0 1 ECN boot process failed 1000 500 2 WAN connection to cell tower successful 4000 200 2 WAN connection to cell tower failed 1000 500 3 Connection to System Software successfully established 4000 200 3 Connection to System Software failed As the table shows, a successful installation should include several 1 second sound bursts, some with a repeated pattern (1 s on, 0.5 s off) to indicate successful network connections. If you receive a 4 s sound burst, the ECN boot process failed. If you receive the repeated pattern (4 s on, 0.2 s off), a network connection failed; check the network cable connection and verify that the network is operational. After installation is verified successful, use the COS Web page interface for the ECN to verify additional functionality. You might also want use the command-line interface to disable the internal audio indicator so that subsequent resets or power events do not cause the audio indicator to output its audio indicator patterns. You can also change the audio indicator patterns by modifying the controller configurable file (CCF); see the COS User’s Guide for information about modifying the audio indicator patterns. 4 dBA measures sound pressure levels relative to 20 µPa (rms) at 1 m.
ECN 7000 Series Hardware Guide 49 5 Field Replacement for an ECN 7000 Series Device This chapter describes how to replace an ECN or an ECN’s battery pack after the ECN has been installed in the field.
50 Installing Components and Overview The ECN 7000 Series of products is designed to allow you to easily replace an ECN unit in the field after installation. For ECN units with the backup battery option, you can also easily replace the battery in the field. Because an ECN is typically installed in a location that exposes it to weather and other hazards, you might need to replace ECN units from time to time. In addition, you might want to replace a working unit with one that includes additional or different expansion cards to provide additional services for your customers. Because the ECN’s cover is not designed to be removed in the field (the cover is secured with one-way screws), you generally cannot perform in-field service for an ECN. If an ECN becomes non-operational, you should replace it in the field with a similarly equipped model to maintain operational service for your customers. You can return the non-operational ECN to your service center for maintenance; see Troubleshooting on page 25 for additional information. Replacing a Pole-Mounted ECN Important: Before replacing an ECN in the field, visually inspect the unit and its surroundings to ensure that the unit is not damaged and that it is safe to handle. You do not need to reinstall the Pole Mounting Bracket to replace an ECN unit. To remove a pole-mounted ECN: 1. If possible, use the COS system software to shut down the unit remotely, before beginning field replacement. 2. Remove all network connections from the bottom of the unit. 3. Remove the power connection from the unit. 4. Remove the screws at the bottom of the unit. These screws will remain attached to the ECN. 5. Lift the ECN from the Pole Mounting Bracket. 6. Attach a carabiner hook to the ECN carry loop to safely transport it to the ground. To install a replacement pole-mounted ECN: 1. Attach the ECN to the Pole Mounting Bracket, as described in Attach ECN to Pole Mounting Bracket on page 30. 2. Secure the ECN to the Pole Mounting Bracket using the screws at the bottom of the unit, as described in Secure ECN to Pole Mounting Bracket on page 31. 3. Connect the ECN to power and to the network, as described in Connect the ECN to Power and the Network on page 32. 4. Verify successful installation, as described in Verifying Successful Installation on page 33.
ECN 7000 Series Hardware Guide 51 Replacing a Pad-Mounted ECN Important: Before replacing an ECN in the field, visually inspect the unit and its surroundings to ensure that the unit is not damaged and that it is safe to handle.

These screws are captive, and remain attached to the ECN. 6. Lift the ECN from the Pad Mounting Bracket. To install a replacement pad-mounted ECN: 1. Attach the ECN to the Pad Mounting Bracket, as described in Attach ECN to Pad Mounting Bracket on page 42. 2. Secure the ECN to the Pad Mounting Bracket using the screws at the bottom of the unit, as described in Secure ECN to Pad Mounting Bracket on page 43. 3. Connect the ECN to power and to the network, as described in Connect the ECN to Power and the Network on page 44. 4. Close the Conduit Housing and lock the door, as described in Close and Lock the Conduit Housing on page 45. 5. Verify successful installation, as described in Verifying Successful Installation on page 48. Replacing the Battery Pack To allow the ECN to run continuously, regardless of external power conditions, the ECN includes a backup battery option. If your ECN includes this option, you will occasionally need to replace the batteries. The battery module is located in its own dedicated compartment accessible from the outside of the ECN enclosure, as shown in Figure 26 on page 52. Within this compartment, a blind-mate electrical connector allows easy installation of the battery module. This separate compartment is weather tight and provides shielding from sensitive electronics and transceivers. Important: Removing any of the front panels compromises the factory seal. You must use the replacement gaskets and sealing screws included with the battery kit to reestablish a proper seal.
52 Installing Components and Figure 26. ECN Battery Compartment Location Required tools for replacing the battery pack: • A standard Phillips screwdriver, Point Size 2 • The battery replacement kit, which includes the battery pack and four sealing screws To remove the battery pack: 1.
