Preface Preface This manual covers basic configuration and installation of the M2400S Wireless Broadband System and applies to the following radio part numbers: M2400S-AP M2400S-SU 2.4 GHz Access Point 2.4 GHz Subscriber Unit FCC Information This device complies with Part 15 of FCC Rules and Regulations.
Introduction Section 1 Introduction Your Trango Broadband M2400S radio system provides a reliable and robust means to deliver broadband access and wireless Ethernet connectivity to a wide geographic region. This section will familiarize you with basic operational concepts as well as an overview of the hardware and the various components of the M2400S system.
Introduction The M2400S radios are powered using "Power over Ethernet" for ease and low-cost installation. A single Cat-5 cable carries both Ethernet and DC power to the radio. Both APs and SUs feature a handy "site survey" tool to check for interference as well as RSSI tools for optimizing antenna positioning.
Hardware Overview Section 2 Hardware Overview This section provides detail about each radio in the M2400S family. Each radio in the M2400S family includes built-in, electronically switchable, dual-polarized antenna as well as a reverse polarity SMA connector for the attachment of an external antenna. For ease of installation all units are designed for outdoor installation and powered by Power-over-Ethernet (POE).
Getting Started The radio’s model number, FCC ID, MAC ID, and Serial # are located on the back side of the radio.

These limits are Side of Radio & Location of Reverse Polarity SMA Connector .600 6.
Getting Started • • • • NETWORK port connection is as follows: If connecting to a COMPUTER, use a Cross-Over Ethernet cable from the NETWORK 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.
Getting Started 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. See Appendix D (Command Set Reference) for a complete listing of commands, and the appropriate opmode for each command. Switch Settings M2400S firmware includes several “switches” which are used to set certain operational parameters of the radios. Switch settings can be changed via the HTTP browser interface or the Command Line Interface.

For a complete list of console commands, type "help" or “?” in the entry field. Logout: This link will end the current browser session with the radio.
Getting Started survey #> NOTE: The majority of the CLI commands will be covered throughout this text as well as in Appendix A, Command Set Reference. Troubleshooting If you cannot telnet into the radio or open a browser session, check cable connections, ensure proper use of cross-over vs. straight-through cable and ensure PC’s subnet is routable to radio’s IP address.
Basic Configuration via Browser Interface Section 4 Interface Basic Configuration via Browser This section describes a few more basic concepts and how to establish a basic wireless link between AP and SU using the Browser (HTTP) Interface. This section is written to address only the most basic steps in establishing a link in the lab, or a bench-top environment.
Basic Configuration via Browser Interface Note: SUs using SU to SU communication must be on the same subnet. CIR UP: Committed Information Rate from SU to AP. Minimum upstream rate (measured in Kbps) at which the SU will attempt to deliver bandwidth to the AP. Maximum setting is 5200. CIR DOWN: Committed Information Rate from AP to SU. Minimum downstream rate (measured in Kbps) at which the AP will attempt to deliver bandwidth to that SU. Maximum setting is 5200.
Basic Configuration via Browser Interface 5. CIR up (SU to AP Committed Information Rate) is the minimum upstream bandwidth for the SU in Kbps. 6. CIR dn (AP to SU Committed Information Rate) is the minimum downstream bandwidth for the SU in Kbps. 7. MIR up (SU to AP Maximum Information Rate) is the maximum upstream bandwidth for the SU in Kbps. 8. MIR dn (AP to SU Maximum Information Rate) is the maximum downstream bandwidth for the SU in Kbps. 9. Enter the Device ID (MAC Address of the SU) 10.
Basic Configuration via Browser Interface 2. Set Base ID or choose default base ID of 0000 (Must match the SU) 3. Set AP ID (00-FF HEX) 4. Set IP, Subnet, and Gateway, or leave at default settings. Keep in mind if you change the IP Settings of the radio you will loose your HTTP session when you save and activate. 5. Choose Active Channel (1-8) 6. Choose Antenna Polarization (H or V) or choose E for external antenna 7. Ensure default Opmode is "ON" 8. Save and Activate Settings 9.
Basic Configuration via Browser Interface Configure Basic SU Parameters In order to establish a working link, the Base ID in the SU must match the Base ID of the AP. SU Basic Setup: 1. Connect to the SU (see Getting Started) and open the Configuration page. 2. Set Base ID (Must match the AP) 3. Set IP, Subnet, and Gateway, or leave at default settings. Keep in mind if you change the IP Settings of the radio you will loose your HTTP session when you save and activate. 4. Ensure default Opmode is "ON" 5.
Basic Configuration via Browser Interface LED Summary At this point it is useful to learn about the various LEDs which can be found on the bottom of the radio. These LEDs can assist the user in determining radio and link status. LED / RESET BUTTON WINDOW 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.
Basic Configuration via Browser Interface On this page the user can immediately see which SUs are currently associated. In the page shown, SU ID# 1 is associated, and SU ID# 17 is not. Consider "Power Off" status synonymous with "not associated." RF Link Loopback Test The RF Link Loopback Test is one of the built-in tools for evaluating the quality of the wireless link. Specify an SU ID and time in minutes to conduct the test. The test is prioritized, so it will take precedence over all other traffic.
Basic Configuration via Browser Interface SU Ranging Test This test reports the SUs distance from AP in miles, received signal strength for uplink and downlink, and SU Tx Power. Use a link budget calculator to analyze results. Significant differences between calculated and actual values could indicate alignment or LOS issues! 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.
Basic Configuration via Browser Interface Channel Table: Assigns channel numbers to actual frequencies of operation. Default settings allow the largest number of channels (8) within the band, while still maintaining 10 MHz channel spacing. 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 can not be changed by the user.
Basic Configuration via Browser Interface Active Channel: The channel currently being used by the radio. RFRx Threshold: Sets the receive threshold of the radio. The radio will not process signals received below this level, so it is very useful for interference mitigation. For a smaller radius of operation use a higher threshold (-65 is higher than -70).
Basic Configuration via CLI Basic Configuration via CLI This section covers how to utilize the radio’s CLI interface to establish a working wireless link. In this section, the most common settings are discussed using the CLI. Topics include: • Access Point Basic Settings • Subscriber Unit Database Settings • Subscriber Unit Basic Settings See Appendix A Command Set Reference for a complete listing of CLI commands.

Deployment Section 6 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.
Deployment Site Survey Example: #> survey 2 v Press [space] then [enter] to stop 2350 2355 2360 2365 2370 2375 2380 2385 2390 2395 2400 2405 2410 2415 2420 2425 2430 2435 2440 2445 2450 2455 2460 2465 2470 2475 2480 2485 2490 2495 2500 2505 2510 2515 2520 2525 2530 2535 2540 2545 2550 #> MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz Ch 1 Ch 2 Ch 3 Ch 4 Ch 5 Ch 6 Ch 7 Ch 8 peak peak peak
Deployment Once the SU is installed and aimed in the general direction of the AP it is time to perform an RSSI (relative signal strength indicator) test to determine the signal strength from the AP. Now you can precisely align the SU antenna for maximum signal strength. Although it is possible to rely upon the subscriber unit’s LEDs for alignment, more precise RSSI readings are available from the command RSSI. In conjunction with the RSSI command, it is also useful to perform the APSEARCH command.
Deployment SU Alignment Using LEDs The LED RSSI indicators on the bottom of the radio provide a handy alignment tool. If all four LEDs are lit, the unit is receiving –64 dBm or stronger. If no LEDs are lit, there is not sufficient signal strength to establish a wireless link. Lit LEDs Signal Strength 0 LED -80 dBm 1 LED -75 to -79 dBm 2 LED -70 to -74 dBm 3 LED -65 to -69 dBm 4 LED -64 dBm and stronger Note: RSSI tool (telnet or LEDs) will show all RF energy on a given freq. i.e.
Deployment Link Management Commands Once the radios are properly aligned for maximum RSSI, ensure the SU’s default Opmode is “ON” and that all configuration parameters are correct. Reboot the SU. Once the SU enters Opmode “ON” the authentication process will begin, and the two radios will begin to associate. From the AP side, there are several basic diagnostics commands such as su ping, su info, and su testrflink to ensure that a reliable RF link has been established.
Deployment [#End] Avg = -51 dB Success. su AP will poll the SU for SU’s current status and will provide information such as SU range from AP, signal strength received at SU from AP, SU temperature, etc. Example: #> su 1 [ 1] pr [as] y [d] 0.0 [rssi at ap] -50 dBm [rssi at su] -60 dBm [ip] 10.8.1.234 [subnet] 255.255.255.192 [gateway] 10.8.1.

In this test, the AP will send 20 large (1512 byte) packets to the SU and the SU will in turn send the same 20 packets back to the AP.
Management • The units buffer up to 1200 frames or 4 seconds worth of RF TX Data frames to support the ARQ algorithm. • The AP unit maintains counters concerning the ARQ algorithm on a per SU basis. The counters shall include the following data: Total Transmitted Frames Total Retransmission Attempts Total “Maximum Attempts Reached” The SU also maintains a counter concerning its use of the ARQ algorithm.
Management Example: su ipconfig 7 192.168.10.10 255.255.255.0 192.168.10.1 In this example SU ID #7’s IP address is changed to 192.168.10.10, the subnet mask is changed to 255.255.255.0, and the gateway is changed to 192.168.10.1. A complete description of these commands and many others can be found in Appendix A Command Set Summary.
Management and an integrated accounting system. For more information on SNMP and its uses you can visit http://www.faqs.org/faqs/snmp-faq/. 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. It gathers health, status and performance statistics from all SUs locally, the agent then responds back to the SNMP manager upon request.
Management By default, the Read Community is set to “public”, and the Write Community is set to “private” in the AP. The Trap Community is “SNMP_trap”. The manager needs to have the same settings in order to communicate with the AP successfully.
