11Commissioning2 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.

13CommissioningFIGURE 4. Management IP2.2.3 Setting the management VLANGo to Configuration > Management > Management VLAN tab (see Figure 5).TABLE 5. 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 MAC addresses of Eth1, Eth2 and wireless port.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.draft

Commissioning14FIGURE 5. Management VLAN2.2.4 Setting the radio parametersThis operation should be done from both the passive and control ends of the link and channel selec-tions should match to ensure the link comes up when properly aligned. Before setting the radioparameters, ensure that the correct radio standard is licensed for the geographic location where theradio is to be installed. For example: FCC for USA or Canada, ETSI for Europe 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. Go to Setup > Commissioning tab (see Figure 6) and click Next Step.FIGURE 6. Step 12. Input the license key and click Modify. Click Refresh to make sure of the configuration.TABLE 6. Management VLANParameter DescriptionManagementVLANConfigure the management VLAN ID for remote login. VLAN range from 51 ~ 4094.Default: 127.ManagementVLAN PriorityConfigure the management VLAN priority. Value from 0 ~ 7. Default: 6.Eth1 If the port is to be used as a part of the management VLAN, set to Yes. If no, it meansthis port is removed from the management VLAN.Eth2Ath1(wireless1)Rate Limit Configure the engress and eggress rate limit for management VLAN. Value from128Kbps ~ 2Mbps. Default: 1024Kbps.draft

15CommissioningFIGURE 7. Step 2INFOIf changing from one radio standard to another, existing license must be cleared.Please contact DragonWave Customer Support if a new license needs to be entered to change theradio standard or geographic location setting.3. Set up wireless parameters according to Table 7.draft

Commissioning16FIGURE 8. Step 34. In Configuration Summary page, set the Setup Frequency field according to Table 9.TABLE 7. Wireless parametersParameter DescriptionLink Name Up to 32 characters, and both numbers and characters are supported. The linkname of both Control Site and Passive Site should be the same.System Role Control Site or Passive Site.One end of Lite should be configured as the Control Site, and the other end thePassive Site.Antenna Stream V+H Stream supported.Bandwidth 40 MHz or 20MHz.Traffic Mode (Uplink/Downlink)50/50For 50/50, the uplink and downlink have the same bandwidth.Guard Interval 400 ns or 800 ns.If the maximum multi-path delay spreads more than 400 ns, we suggest to use800 ns. Leaving the guard interval at 400 ns (the default) works in most applica-tions. For installations where the link is over long stretches of water, or non-line ofsight applications with lots of multi-path signals, selecting 800 ns guard intervalcan improve the performance.Wireless Port RateLimitRate limit on Wireless port. It will only take effect while the value is lower than theWireless Throughput.Static Modulation If ACM is disabled, Lite will use Static Modulation as Tx side modulation. This isthe modulation selected for this link and will not change unless ACM is enabled.Tx Power Tx power on each radio. Limited by EIRP. This rate limit is automatically assignedbased on the modulation selected.draft
