INITIAL LINE UP ROI-S057503-13. INITIAL LINE UPThis NLite E Section explains instructions for the initial lineup of the equipment. Included is information on start-up, shut-down, IDU and ODU equipment setting, antenna orientation and lineup test between two stations.When the NLite E Monitor is used for RX LEV monitoring, connect the X0818 NLite E Monitor to the ODU. The NLite E Monitor operates on a dry battery (6F22/9V).Notes: 1. Insert the battery with correct polarity.2. When the NLite E Monitor will not be used for extended periods of time, remove the battery to avoid damage from battery leakage and corrosion.3. When the NLite E Monitor will be connected to the ODU, control corresponding ODU to Antenna Alignment mode using LCT in Maintenance ON.
ROI-S05750 INITIAL LINE UP3-23.1 Start-upThe procedure for starting the equipment is shown in Chart 3-1.Warning: 1. The –48 V DC is superimposed on the centre conductor of the IF coaxial cable between the MODEM and the ODU. Connecting test equipment directly to this terminal may damage it and touching the coaxial cable core may cause electrical shock.2. Do not disconnect the IF cable between the MODEM and the ODU in operating condition, to avoid damaging the NLite E , turn the IDU power OFF before connecting/disconnecting the IF cable.3. Do not allow open or short circuit of ODU TX output with the TX power on conditions. Perform the TX Mute control in the Maintenance mode or turn the PWR switch off at the IDU before disconnecting cable or feeder from the ODU TX output.4. After turning ON the equipment, wait at least 1 minute before turning it OFF again. Repeatedly turning the power ON and OFF within a short interval may cause the NLit E to fail.Caution: 1. In a system using the OPTICAL OC-3 INTFC, do not stare at the laser beam or look at it directly with optical instruments. Otherwise, it may hurt your eyes (Class 1 Laser Product).2. Be careful top surface above MODEM of the IDU is hot in operation.3. When replacing the MODEM, OC-3 INTFC or DC-DC CONV (optional) turn off the PWR switch and disconnect all cables connected to the module which is to be replaced.4. When dismounting the ( ) INTFC, turn off the PWR switch on the MODEM and disconnect all cables connected to the ( ) INTFC.5. In the SONET XPIC system, the system parameter setup must be performed at the Master station first, then at the Sub Station.6. In the SONET XPIC system, the Main Master and Sub Master channels must be connected to one dual polarized antenna.

ROI-S05750 INITIAL LINE UP3-16Safety Guideline for Microwave Radiation HazardThe Microwave and Millimeter-wave that NLite E series are transmitting is at a very small radiation level and never has been reported to effect human health. Advanced countries concerned about health hazards have started to regulate the radiation levels. The operator should not work near the parabolic antenna during RF transmission. The area in front of and to the side of the antenna show high radiation levels. Please see below figure and calculation sample 1. The front side of antenna presents a high power density in the antenna beam area. Therefore, the user of this system should pay attention not to radiate the beam against humans at any time. (Please refer below calculation sample 2)ODU- 90 to +90 degrees ANTENNAHazard Area of RadiationIn addition, the Power density and Field strength level is calculated by equation below. 10 × KPower density S (mW/cm2) = 40 × π × R2P+G−3010Where: P = Output power of ODU (dBm), G = Antenna Gain (dBi), (in consideration of the angle from antenna) K = Reflection factor =2.56 (given), R = Distance between Human and Antenna (m)Calculation example 1, (90 degree side of antenna)NLite E = 18 GHz/+23 dBm, Antenna diameter = 0.6 m, 0 degree antenna gain = 39 dBi, 90 degrees side antenna gain = −24 dBi, (90 degrees attenuation = −63 dB), Distance = 0.1 mPower density S (mW/cm2) = 0.0016 ≤ 0.01 Calculation example 2, (0 degree, front side of antenna)NLite E = 7 GHz/+27 dBm, Antenna diameter = 1.8 m, 0 degree antenna gain = 40 dBi, Distance = 100 mPower density S (mW/cm2) = 0.01
