Chapter 2 Installation Installation Tips

CAUTION! Use of controls or adjustments or performance of procedures other than those specified here may result in hazardous radiation exposure. Follow these tips when installing a GigaSpire device. For subscribers using data services, all data wiring inside the home must be CAT5 cable or better. Make sure subscriber connections are tightened properly. Check the contents of each box carefully as you receive them. Components may not be located where you might expect them due to certain items being tested immediately before shipment. Proprietary Information: Not for use or disclosure except by written agreement with Calix. 19 Install Guide About Wi-Fi Placement Certain building materials are particularly effective at blocking Wi-Fi signals (see table below) and should be considered when locating the GigaSpire. Line of sight is not necessary since MIMO technology takes advantage of reflections in the over-the-air path to carry additional data. However, Calix recommends that when possible, Calix GigaSpires should be placed in a centralized location within the home to yield the best possible results for Wi-Fi coverage. Building Materials and Their Effect on Wi-Fi Signals Material Wi-Fi Attenuation Wood, Drywall, Particle Board, Tile Glass Water Bricks, Cinder Block Plaster, Stucco Concrete Tinted or Low-E Glass (metalized) Metal Low Low Medium Medium High High Very High Very High Note: The lower the attenuation, the better the performance. Installation Variables Before installing the GigaSpire, consider what additional services may be implemented. Various access points are available on the back of the unit which may or may not be used. Prior to determining the unit's final location, you need to account for the following variables:

Optional: Where will the Ethernet cable be routed?

Tabletop Mounting the GigaSpire BLAST Any Calix GigaSpire BLAST can be mounted flat on a tabletop, in a tower configuration. Four (4) rubberized feet are pre-installed on the bottom of the unit to provide a non-skid surface when placing the GigaSpire on a table or shelf. Keep the following information in mind when considering tabletop mounting:

Due to component placement inside the chassis, do not remove the rubber feet that are installed on the bottom of the unit. Locate the GigaSpire on the desktop in a location that is unlikely to be bumped or jostled. Make sure that the Ethernet cable (if used) and power supply wiring attached to the GigaSpire are secured properly and out of harms way. Note: Once the GigaSpire is connected and turned up, Wi-Fi network parameters are persisted in memory. For this reason, if power is lost to the GigaSpire, it will be re-

discovered on the network automatically, without operator intervention. Proprietary Information: Not for use or disclosure except by written agreement with Calix. 23 Install Guide Wall Mounting the GigaSpire BLAST The Calix GigaSpire BLAST u6 and u12 series can be wall mounted using the optional wall mount bracket. These GigaSpire BLAST models includes a 6mm captive receptacle built into the base for attaching to the captive M6 screw assembled into the wall mount bracket. Keep the following information in mind when considering wall mounting:

Locate the BLAST on the wall in a location that is unlikely to be bumped or jostled. Make sure that the Ethernet cable(s) (if used) and power supply wiring attached to the GigaSpire are secured properly and out of harms way. Note: Once the GigaSpire is connected and turned up, Wi-Fi network parameters are persisted in memory. For this reason, if power is lost to the GigaSpire, it will be re-

discovered on the network automatically, without operator intervention. To wall mount the GigaSpire BLAST Typical Wall Mount Location 1. Find a suitable location for attaching the wall mount bracket to the wall. Be mindful of the power source and Ethernet cable requirements then determining a mounting location. 2. Using the wall mount bracket as a template, mark the two screw locations on the wall, making sure the bracket is level. Note: The holes of the bracket are designed to accommodate a #8 screw (not provided). Depending on the material you are attaching to, use a screw of sufficient length and strength to support the GigaSpire once attached to the bracket. Note: If attaching to sheet rock or gypsum board, Calix recommends using a wall anchoring system to ensure the bracket is securely attached to the wall.

From a best practices standpoint, keep the following in mind:

Calix recommends mounting the BLAST as high as possible for Wi-Fi performance reasons. However, this deployment scenario still mandates that an AC power outlet is located within the power cord distance of the Wi-Fi source. If installing in a greenfield environment (initial installation), plan on placing the GigaSpire within 4 feet of the power supply. As an alternative, longer power cords are available to extend the distance between the BLAST and the power supply. Calix also recommends keeping cabling neat and well secured wherever possible. A tidy installation allows for increased safety and an overall neater appearance. Common tools used for this purpose include cable ties and velcro straps for routing cable out of the way. Also, custom made wall plates are often used where cabling is hidden behind a wall. Example Wiring Scenario - Custom Plate EXAMPLE WIRING SCENARIO To Downstream Ethernet Devices (x4) LAN1 LAN2 WAN 1 LAN3 LAN 4 To Upstream Router VAC to 12VDC Power to Upstream GigaSpire BLAST POTS 1 POTS 2 8219 To Downstream POTS Devices (x2) With so many options available for deployment, your network architecture is no doubt going to be different from other subscribers. The diagram directly below is one of hundreds of options. This particular example provides the following:

A Local Convergence Point (LCP) for bringing fiber into the home. In this case, a Calix 803G GPON GigaPoint is located near the services panel in a climate controlled utility room or storage room that can be locked with limited access by others. A customized interface panel (see above) for providing LAN, WAN, and POTS ports pre-wired near the BLAST. This allows for short cable runs and an overall cleaner deployment reducing clumsy and ill-terminated cable runs. Proprietary Information: Not for use or disclosure except by written agreement with Calix. A Calix GigaSpire BLAST mounted near the ceiling on the optional Wall Mount Bracket. This device provides Wi-Fi radios inside the home in a location that provides the optimal Wi-Fi signal throughout the home. The BLAST also provides a mechanical hub for deploying additional Ethernet ports or POTS ports in the home. In this particular deployment, a UPS is not being used and as such, only the 2-pin barrel connector is needed for powering the GigaSpire. 26 EXAMPLE WIRING SCENARIO Utility Closet Upstream Router (Calix 803G GigaPoint) Internet Source Local Convergence Point (Fiber) Incoming Power (12 VDC) POTS Bundle Ethernet/POTS Cabling Together Living Space POTS-RJ 11 (x2) Gigabit LAN Ethernet, RJ45 (x4) 2.5G Gigabit WAN - RJ45 (u6.2) 1.0G Gigabit WAN - RJ45 (u12, u12X, u6.1) Proprietary Information: Not for use or disclosure except by written agreement with Calix. 27 Install Guide Proprietary Information: Not for use or disclosure except by written agreement with Calix. Chapter 3 Final Set-up and Testing BLAST Reset Behavior The reset button will do a "restore to defaults" when held for 10 seconds which clears everything except what was set by Smart Activate (restores defaults to whatever was set up during installation by the service provider). Note: Performing a reset does not remove the default SPID and ACS URL that has been assigned to the system. This is designed intentionally, so that u6 systems cannot be taken out of service by the subscriber if they were to cancel and/or move to another service provider. The SPID and ACS URL are unique for each service provider. Calix EDGE systems support a variety of system reset functions and provide multiple methods for invoking each of these functions, as described in this topic. Calix defines these functions and behaviors as follows:

1. Basic reset (reboot): Restarts the router. 2. Configuration reset: Resets the RG configuration settings (those visible to the subscriber/Admin user in the EWI, such as SSIDs, LAN IP scope, etc.) to defaults, but retains operator-configured management settings (those visible only to the Support user in the EWI, such as ACS URL and SPID). 3. Factory reset: Resets the router (and any attached mesh satellites) to factory default settings. A factory reset also removes devices from network management systems, including Calix Support Cloud and the Smart Home Admin Dashboard, where applicable. These reset functions can be used as troubleshooting and/or operations tools for reset/removal scenarios, whether the device is deployed as an RG or as a subtended WAP or Satellite (GigaSpire BLAST or GigaMesh). Hardware-invoked resets behave differently depending on how long the reset button is pressed, as described below. Proprietary Information: Not for use or disclosure except by written agreement with Calix. 29 Install Guide Function Where Performed 1 Basic Reset 2 Configuration Reset Factory Reset Hardware: Press Reset button once for 1 second Software: EWI > Utilities > Reboot Hardware: Press and hold Reset button for 15+
