E BEAM User Manual & Modem Installation Guide Modem Overview For optimum performance, the E BEAM modem must be stored in a cool, dry, and clean room. These devices must not be stored outdoors or in a place subject to extreme temperatures or high humidity. Back Panel The back panel of the E BEAM modem has two 48 V wall plug power adapter connections, RS-232 port, and a ground connection.
E BEAM User Manual & Modem Installation Guide LED Descriptions LED Power 100Mbps Fault Safety Fiber Data Fiber Link Ethernet Data Ethernet Link Description Green when connected to a power source. Amber when a proper link is established and the units are connected at 100 Mbps. When off, it is operating at 10 Mbps. Red when an internal firmware fault is detected in the modem. Red when a heater/safety interlock circuit fault has occurred.
E BEAM User Manual & Modem Installation Guide 2 Modem Installation Mounting the Modem The E BEAM modem must be stored in a cool, dry, and clean room. The temperature range for the modem is 0˚ C to +50˚ C (32˚ F to 122˚ F). Do not store the modem outdoors or in a place subject to extreme temperatures or high humidity. To prevent damage to the modem, it is recommended to mount the modem in a 19 inch telco rack.
E BEAM User Manual & Modem Installation Guide Next, connect the fiber optic cables to the modem. (*Note: It is recommended that the lettered fiber cable be connected to the “TX” fiber optic connection on the modem.) The Safety LED should turn on if the fiber optic cables are not connected to the antenna. Connecting the fiber optic cables to the antenna activates the lasers and should turn the Safety LED off.
E BEAM User Manual & Modem Installation Guide LED Descriptions As was previously discussed, the front panel of the modem is equipped with eight light-emitting diodes (LEDs). LED Description Power Green when connected to a power source. 100Mbps Amber when a proper link is established and the units are connected at 100 Mbps. When off, it is operating at 10 Mbps. Fault Red when an internal firmware fault is detected in the modem. Safety Red when a heater/safety interlock circuit fault has occurred.
E BEAM User Manual & Modem Installation Guide cables using an 850 nm optical light source and an 850 nm/dBm power meter. If there is no damage to the fiber optic cables, and the problem persists, please call Whirlwind Technical Support for assistance. Once the laser link between the antennas is functioning, the fiber optic link LED will turn on.
E BEAM User Manual & Modem Installation Guide modem is connected to a valid Ethernet source which is set to 100 Mbps Full-Duplex and not “Auto Negotiate”, and that the Ethernet Link LED is on. Also, use an 850 nanometer (nm) fiber optic power meter to verify that the received power is not greater than +2 dBm. Unplug the “RX” fiber cable and plug it into a fiber optic power meter to measure the dBm value.
E BEAM User Manual & Modem Installation Guide HyperTerminal Configuration for Optical Statistics Set up a new connection via HyperTerminal. Name the connection “EBeam Optical Data”. The default serial connection is COM1. If a different COM port is used, select the appropriate COM port. The settings for the COM port should be 9600-8-N-1 and no flow control.
E BEAM User Manual & Modem Installation Guide Use a straight through, male-to-female, dB9, RS-232 cable to connect from the back panel of the modem to the designated COM port on the PC or laptop. Once HyperTerminal screen has been set up properly, the screen is ready, and the cable has been connected, press and hold the Shift and question mark (?) key down simultaneously. The stats shown in the window below will appear on the HyperTerminal screen.
E BEAM User Manual & Modem Installation Guide Understanding Received Optical Power Level Readings Depending on where in the system the received optical power level is being measured and the distance between the antennas, the readings will differ slightly. The two sections below define the power level ranges for readings at the modem and the readings obtained by the modem utility. Received Optical Power at the Modem The table below displays the nominal received optical power levels at certain distances.
E BEAM User Manual & Modem Installation Guide Troubleshooting Guide If the link is inoperable, check the modem LEDs for the following: 1. Check power on LED a. Power LED off i. Power interruption 1. Unplugged power supply 2. Unplugged, turned off, or bad power strip/UPS 3. Thrown electric breaker ii. Defective modem b. Safety Shutoff/Interlock LED on i. Safety Shutoff/Interlock interruption 1. Fiber unplugged from modem 2. Fiber unplugged from antenna 3. Fiber damage (e.g. cut) ii. Defective modem 2.
E BEAM User Manual & Modem Installation Guide * Although all of the LEDs may be working properly, there can still be errors in data transmission. When the signal strength is too high, it can cause the unit to malfunction during data transmission. Too much signal strength causes receiver saturation. A temporary solution for this problem is to slightly pull out the ST connectors approximately 1mm on the modem.
