Understanding Silver Spring Networks Access Points 1 1 About Access Points About Access Points Overview The Silver Spring Access Point (AP) provides the central link between endpoint devices and network control and monitoring. It is the connectivity between intelligent endpoints and the utility’s back office. Its flexible communication features extend the reach and coverage of the network to thousands of customer premises, through scalability that lowers ownership costs.
Understanding Silver Spring Networks Access Points 1 About Access Points Division Multiple Access, Long Term Evolution, High Speed Packet Access, single carrier Radio Transmission Technology) Wide Area Network (WAN) interface, or with a 10/100 Ethernet interface. The Access Point provides a method for implementing the last mile utility information and control network.
Understanding Silver Spring Networks Access Points 1 About Access Points Figure 2 shows an Ethernet AP. Figure 2. Silver Spring Networks Access Point (AP) Cellular antenna Power connector NAN antenna Battery Backups APs can be configured with battery backups. In the event of a power failure, the battery backup can provide continuous operation for at least eight hours. Silver Spring Networks suggests as a best practice, a battery backup within the Access Point.
Understanding Silver Spring Networks Access Points 1 About Access Points The design float life of Silver Spring-IBP products is up to eight (8) to ten (10) years at room temperature (25°C/77°F) and under proper charging conditions. This design life has been confirmed by the use of accelerated testing methods that are widely accepted by both manufacturers and users of sealed-lead batteries. High temperatures are used to accelerate the aging process of the battery under test.
Understanding Silver Spring Networks Access Points 1 About Access Points Cellular Modem Currently, the modem is a Sierra Wireless AirLink, RavenX, RavenXT, or RavenXE depending on AP model and country location. Addressing Schemes Silver Spring’s addressing scheme is based on the Internet Protocol (IP) suite. Each network device has one or more IPv6 addresses within the LAN. The Access Point will typically have an IPv4 address assigned to the WAN side.

Understanding Silver Spring Networks Access Points 1 About Access Points Declaration of Conformity with regard to the R&TTE Directive 1999/5/EC This declaration is only valid for configurations (combinations of software, firmware, and hardware) provided and supported by Silver Spring Networks Inc. The use of software or firmware not provided and supported by Silver Spring Networks Inc. may result in the equipment no longer being compliant with the regulatory requirements.
Understanding Silver Spring Networks Access Points 1 About Access Points Maintenance Procedures If an Access Point experiences an outage, all end point devices and Relays that were associated with it will converge on their secondary Access Point as found within their NodeQs. This alleviates outages due to Access Point failure. UtilityIQ-Network Element Manager (NEM), GridScape, or HCM is then alerted of an Access Point outage, and forwards this message to the operator.
Understanding Silver Spring Networks Access Points 1 About Access Points Customers have used the following alternative backhaul technologies: • Distribution Substation Backhaul (for example, fiber) • WiMAX • Satellite Radios The design rule for Access Point to RF devices is 1 to 5,000. At this ratio, the maximum data throughput required from a WAN solution is 40kbps per Access Point. Based on real-world data on a network of this size, the average wireless speed is measured at 2.
Understanding Silver Spring Networks Access Points 1 About Access Points Figure 4 illustrates data collected from a live customer network over a period of one week. As shown, the average bandwidth consumed by Advanced Metering traffic is approximately 15 Kbps or 15%, leaving 85% for other smart grid solutions such as DA or DR (disaster recovery). Figure 4.

Understanding Silver Spring Networks Access Points 1 About Access Points Responding to a WAN Failure An AP might not be reachable because the device cannot dial out on the WAN. The device continues to try dialing out until it is either able to connect, or it has dialed 308 times. If it can connect, the device notifies the event management program that it has successfully recovered. If it cannot, then the modem resets itself.
Understanding Silver Spring Networks Access Points 1 About Access Points Address Management For the LAN, a DDNS (Dynamic DNS) system is used. Each device has one or more IPv6 addressed assigned to it, based on its location in the network and route out of the LAN. These addresses are then stored at the head end and used for all communications with the devices (ping, trace, reads, etc.), giving the customer a true, native end-to-end IP network.
Understanding Silver Spring Networks Access Points 1 About Access Points Configuration To facilitate the configuration and remove the chance for human error (for example, typos) a simple shell script is generated and run from a Unix-based laptop which has a Silver Spring Field Service Unit attached to the USB port. All Silver Spring APs are configured during the manufacturing process to ensure that the proper profile (Network ID, etc.) is included.

Improper installation could void the userʹs authority to operate the equipment. The device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1.
Understanding Silver Spring Networks Access Points 2 FCC and Government Guidelines CAUTION: Changes or modifications not expressly approved by Silver Spring Networks could void the user's authority to operate the equipment. FCC Guidelines for Devices Containing a Transmitter Module The following is an extract from FCC PART 15 UNLICENSED MODULAR TRANSMITTER APPROVAL, DA 00-1407, Released: June 26, 2000, Section 6 describing labeling requirements for devices containing a modular transmitter. Section 6.
Understanding Silver Spring Networks Access Points 2 FCC and Government Guidelines Safety Information WARNING: Severe shock and explosion hazard! Touching energized parts can result in massive equipment damage, and severe injury or death. Short-circuiting energized parts will result in blinding flash and explosion. Opening and closing electrical circuits can also produce dangerous and explosive arc flashes. Involuntary muscular reactions associated with electrical shock may result in other injuries.
Understanding Silver Spring Networks Access Points 2 FCC and Government Guidelines • 120V current can be just a lethal as higher voltages because current flow through a body depends upon the bodyʹs resistance. • Do not trust insulation and/or weatherproofing on a wire as protection from shock. • Use electrically insulated tools. Inspect portable electrical equipment or tools for defects and remove any defective devices from service immediately.
Understanding Silver Spring Networks Access Points 2 FCC and Government Guidelines • Only use ladders made of non-metallic, non-conductive material. They should be the proper size and type for the work intended. Inspect ladders for wear and breakage. Remove any oil, grease, or other slippery materials. • Do not set the ladder at too steep or too shallow of an angle. A rule of thumb is to stand erect with your toes against the bottom rails of the ladder, with your arms extended straight out.
