Getting Started • Connect a Cat-5 (straight through) Ethernet cable (we recommend shielded twisted pair) between the ODU (out door unit) port of the J-box and the RJ-45 connector on the radio. Note that this cable will carry power-over-Ethernet (PoE). • If connecting to a COMPUTER, use a Cross-Over Ethernet cable from the NET port of the J-box to the computer’s Ethernet port. If connecting to a HUB, SWITCH, or ROUTER, use a Straight-Thru cable. • Plug the AC adapter into an AC outlet.
PAGE 10
Getting Started APs and SUs can be in one of two Opmodes (“ON” or “OFF”). When in Opmode “OFF,” the AP is not transmitting and it is not attempting to associate with SUs. Alternatively, when in Opmode “ON,” the radio is transmitting and is attempting to associate. Several functions, such as the site survey function and the SU RSSI function, can only be performed while the radio is in a particular Opmode.

Basic Configuration via Browser Interface LED Summary At this point it is useful to learn about the LEDs that can be found on the bottom of the radio. These LEDs can assist the user in determining radio and link status. RSSI LEDs (YELLOW) - In all modes except "Survey," the unit's four yellow LEDs indicate the level of RF signal being received from a valid AP. ASSOCIATION LED (GREEN) Blinking once every second in Opmode "OFF" (AP and SU).
PAGE 20
Basic Configuration via Browser Interface Link Control Page The radio’s firmware includes several useful tools to assist in determining which SUs are associated and the quality of each link. One method for verifying link quality is by using the Link Control page. On this page the user can immediately see which SUs have associated. In the page shown, SU ID# 1 is associated, and SU ID 17 is not. Consider "Power Off" status synonymous with "not associated.
PAGE 21
Basic Configuration via Browser Interface SU Ranging Test This test reports the SU’s distance from the AP in miles, received signal strength for uplink and downlink, and SU Tx Power. Use a link budget calculator to analyze results. Advanced Setup Page The Advanced Set up page includes several important parameters including RF TX Power, RF RX Threshold, Target RSSI from SU (AP only), and Channel Table. RF TX Power: Sets the conducted RF power output of the radio. Highest allowable setting is 26 dBm.
PAGE 22
Basic Configuration via Browser Interface Other Key Parameters This section describes the remainder of the parameters listed on the System Information page. Most of these parameters are the same for both APs and SUs. Hardware Version: Hardware version is factory-set and cannot be changed by the user. FPGA Version: Low-level field programmable gate array firmware currently loaded on the radio. Normally the FPGA firmware will not require upgrading. Firmware Version: Main firmware.
PAGE 23
Basic Configuration via Browser Interface Site Survey Page The Site Survey page provides a useful tool for detecting and measuring interference. The radio must be in Opmode “OFF” in order to use this feature. Enter the number of minutes desired for the survey, and select the polarization H, V, or E (for an external antenna). Click "Start Survey." A survey of the default 4 channels will be performed. Results are reported in dBm per channel as average and peak.

PAGE 35
Mounting Hardware Installation Notes Access to the radio’s RJ-45 Port and LED status lights are purposely located at the bottom of the radio to minimize the risk of water intrusion. Do not mount the radio upside down. The J-Box is not a weatherized device, and must be located either indoors or in a weather-protected cabinet. Shielded twisted pair Cat-5 cable is recommended for all installations unless the cable is placed in metal conduit.

Deployment Section 7 Deployment Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process consists of the following steps: • Site Selection • Site Survey • Channel Planning • SU Antenna Alignment • Link Management Commands Site Selection Proper site selection for your AP will help ensure a successful deployment.
PAGE 37

Deployment In conjunction with the RSSI command, it is also useful to perform the apsearch command that will tell you which AP is providing an adequate signal at the location of the SU. AP Search 1. 2. Ensure AP is in Opmode “On.” Run the apsearch command to verify which AP is providing the strongest signal strength. In this example, an AP is detected on channel 1, polarization horizontal. Further, the Base ID is 1234, and the MAC address is 00 01 DE 15 5C D0.
PAGE 39
Deployment 3 LED 4 LED -65 dBm -60 dBm Collocation and Channel Planning With proper channel planning and adherence to installation guidelines, multiple M900S APs may co-exist and operate interference-free on the same tower or building. The main consideration when collocating APs is to ensure at least 10 ft. of vertical separation. See the diagram below for collocation spacing, and a suggested channel plan.
PAGE 40
Deployment In establishing and diagnosing the quality of the link between the AP and SU(s), there are a few commands that are especially useful. All of these commands are performed at the AP. A summary of these commands follows: su Displays the status of all SUs in the AP’s SUDB. SUs in the SUDB will appear by SU ID, and are classified into one of the following status categories: Associated, Associating, and OFF. Example: #> su [Priority] 88 [0] [1] [2] [3] 88 [4] [5] [Associating] [Power Off] Success.

Management Section 8 Management Section Topics: • Radio Management Access using TCP/IP • SU Management from the AP’s command set • SNMP Radio Management Access Via TCP/IP The IP Address of an M900S radio is for management purposes only. The IP address is not used for purposes of routing or passing traffic. Users should take care to set appropriate IP schemes for all management activities including upgrading the radio’s firmware.
PAGE 44
Management Loading Multiple SUs into the SUDB using DLOAD Command To load a full database of SU entries into the AP’s SUDB, you need to create a subscriber database in ASCII text file format. As shown below, each row represents all information for one SU. Each column is an information field, which includes: SU ID, SU to SU group, service level, CIR, MIR, and MAC address.
PAGE 45
Management The Trango SNMP solution supports MIB-II (system only) and the Trango proprietary Management Information Base (MIB). The SNMP agent resides on the AP ONLY. The AP gathers health, status, and performance statistics from all SUs locally, then responds back to the SNMP manager upon request. Users interested in using the SNMP functionality should review the entire M900S MIB for a complete understanding of its features. The M900S MIB is available for download at: http://www.trangobroadband.
PAGE 46
Management SNMP Setup Trango Broadband provides only the MIB portion of the SNMP Management system. The radios act as individual agents, and it is up the user to provide an SNMP Manager software from a third party vendor. Below is an example of the setup process for SNMPc from Castle Rock™. 1. 2. Unzip trangopkg.zip file to a local temporary directory. Go to your local temporary directory, you will see 4 files shown below. a. b. c. d. 3. 4. 5. 6. trango_m900sap_1p0.mib – M900S AP MIB file trango.
