LITE, R1.0, Operation and Maintenance Guide, Issue 1 5Commissioning2 Commissioning2.1 Before commissioningBefore LITE system become operational, initial configuration steps need to be carried out first. Andthe Commissioning wizard is recommended to be executed prior to the hardware installation on site.The LITE system can be accessed by the Web Browser on a PC, such as Google Chrome (28.0 orhigher), Firefox (26.0 or higher), IE (9.0 or higher). If Firefox or IE is to be used, Adobe Flash Playerplug-in has to be installed first. (To download Adobe Flash Player, go to website http://get.adobe.com/cn/flashplayer/.)Before logging into the LITE Web interface, the network configuration of the PC must be set asFigure 1. We suggest setting the PC IP address to 192.168.255.1 and subnet mask255.255.255.248. This IP address is used to access LITE when the management PC is directly con-nected to LITE system. By default, the private IP address of LITE is 192.168.255.3 and the subnetmask 255.255.255.248.FIGURE 1. PC network configuration2.2 Commission steps2.2.1 Logging inSteps1.

Management IP2.2.3 Setting the management VLANGo to Configuration > Management > Management VLAN tab (see Figure 5).TABLE 4. Management IPParameter DescriptionPublic IP Address Public IP is used to access LITE over Management VLAN (Tagged, typically using aswitch or other intranet connectivity). It is for in-band management.Public IP MaskPublic GatewayPrivate IP (Eth 1) Private IP is used for commissioning.Private IP Mask (Eth1)Local ManagementIPLocal Management IP is used to access LITE locally over one of the Ethernet portsuntagged, for example, from a PC running WebLCT. It is also for out-of-band man-agement.Local ManagementIP MaskMAC 1 Display the learned MAC addresses of Ethernet and Wireless ports.MAC 2MAC 3Node Type This field is used in chain site configuration. When it is changed to Node with P+Eoutput, the private IP would be automatically changed to 192.168.255.4, to avoid IPaddress conflict in the chain site.
Commissioning8LITE, R1.0, Operation and Maintenance Guide, Issue 1FIGURE 5. Management VLAN2.2.4 Setting the radio parametersBefore setting the radio parameters, ensure that the correct radio standard is licensed for the geo-graphic location where the radio is to be installed. For example: FCC for USA or Canada, ETSI forEurope and Asia, etc.It is also important to verify that the correct maximum speed required is licensed, as per the linkdesign specified for the radio in this location.Steps1.

Pd = power density in mW/cm2the limit of MPE, 1mW/cm². 43Declaration of Conformity for RF Exposure This microwave outdoor unit product has been found to be compliant to the requirements set forth in CFR 47Section 1.1307 addressing RF Exposure from radio frequency devices as defined in Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. Antennas with less than 23.5 dBi gain should be located at a minimum of 39.03 cm in more from the body of all persons. Calculation Formula: Pd = (Pout*G)/(4*pi*r2) Where Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 r = distance between observation point and center of the radiator in cm Pd is If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. LITE, R1.0, Operation and Maintenance Guide, Issue 1
Federal Communications Commission (FCC) Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generate, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:  Reorient or relocate the receiving antenna.  Increase the separation between the equipment and receiver.  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. RF exposure warning This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment must be installed and operated in accordance with provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 39.03 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter.
IC Radiation Exposure Statement for Canada This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent is otropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. User manuals for transmitters equipped with detachable antennas shall also contain the following notice in a conspicuous location: This radio transmitter (identify the device by certification number, or model number if Category II) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste,ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.
