1 Installation Preparation 1.1 Installation Preparations 1.1.1 Collecting the Technical Documents The technical documents, include network diagram, equipment room facility plan, installation design drawings, wiring drawings, etc, should be provided by the party who is responsible for preparing the documents under the request of purchasing party. Copies of the documents should be provided by the purchasing party to the gateway supplier prior to the shipment. This manual and < Operation Manual for MX Gateway Series > should be provided to the purchase party in the shipment. A <Site Survey Report> must be completed prior to the installation. When all required conditions are satisfied, <Installation Project Agreement> should then be prepared and signed-off, and <Installation Project Plan> should be prepared. 1.1.2 Tools and Meters The tools and meters listed in table 1-1 are required for the installation. Table 1-1 Tools and Meters for the Project Items Philips Screwdriver Slotted Screwdrivers Diagonal Cutter RJ45 & RJ11 Crimping Tool Wire Stripper RJ45/RJ11 Cable Tester Angle Square Spirit Level Multimeter Antistatic wrist strap Cable Tie Gloves Antistatic Gloves 1.2 Site Requirements 1.2.1 Temperature and Humidity Check the temperature and humidity of equipment room. To ensure the normal operation and long service life of the gateway, the temperature and humidity in the room should be kept at the proper range. The humidity in the equipment room should be kept between 10% and 90% (non-condensing). Abnormal humidity condition may cause problems to the gateway: Long term high humidity may lead to bad insulation and even cause electricity leakage, mechanical property change and corrosion. Low humidity is likely to leave captive screws to loose due to static electricity built up and the insulation washer shrunk. Shanghai New Rock Technologies, Inc. Page 7/23

The temperature in the equipment room should be kept between 0 and 40. Abnormal temperature condition may cause problems to the gateway: High temperature acceralets aging of electrical parts and insulation materials. Low temperature, however, may destablize the operation of gateway. 1.2.2 Cleanliness Dust is very harmful to the safe operation of the gateway. Dust that is adsorbed by static electricity acts as insulator, which not only affects the service life of the gateway but also leads to communication failure. Therefore, the room for the gateway must be kept clean. To ensure adequate ventilation to keep the gateway from overheating, there should be adequate clearance for the air intake and the air exhaust vents. Keep at least 6 cm clearance at the left and right side of the chassis where the air intake is and at least 15 cm clearance at the rear of the chassis where the exhaust vents located. The rack for MX51, MX100-AG and MX120 should have a good ventilation system. 1.2.3 Power Supplier Check the power supply system against the electrical specification of the gateway. The electrical specification is listed in Table 1-2. Table 1-2 Power Requirements of MX Gateway Series Model Rated Voltage Input Voltage Power Max Power Range Frequency Consumption Range MX8 DC 5V 5V~9V DC 15W MX51 110V or 220V 100V~240V 47Hz~63Hz 50W MX100-AG 110V or 220V 100V~240V 47Hz~63Hz 75W MX120 (Main Chassis) MX120 (Expansion Chassis) 110V or 220V 100V~240V 47Hz~63Hz 75W 110V or 220V 100V~240V 47Hz~63Hz 50W : MX8 is equipped with an AC to DC adapter 1.2.4 Grounding There is no ground tab on MX8 and it gets power from an AC to DC adapter. To maintain good voice quality, proper grounding of the AC supply is critical to minimize the noise from the AC interference. Therefore, the following conditions must be ensured: The AC power outlet has a protection ground contact. The ground contact of AC supplier must be grounded properly. Avoid sharing the multi-outlet power strip with other devices that may generate elctrical interference. MX51, MX100-AG and MX120 are chassis based with ground tab. In a site that can not provide ground for the chassis, you must make sure that the AC supply satisfies the requirement described above for MX8. In a site that can provide ground for the chassis, the ground tab at the rear panel of chassis for MX51, MX100-AG and MX120 must be properly grounded. 1.2.5 Electromagnetic Environment Any possible interference source, wherever it is from, impacts the gateway negatively. To resist the interference, make sure that: Keeping the gateway far from radio transimitting station, radar station, and high-freqency devices. Use electromagnetic shielding when necessary. The gateway is capable for secondary lighten protection on wires and cables that connected to outside buildings.the site must provide the primary lighten protection. Shanghai New Rock Technologies, Inc. Page 8/23

The power supply system should be used independently as much as possible and effective measures of preventing electric grid from interference should be adopted. Ensure a good power grounding effect of equipment or add a lightning protector. 1.2.6 Other Facilities Rack/Workbench MX8 can be placed on a clean and flat workbench. Ensure that the workbench is stable and well ventilated. MX51, MX100-AG and MX120 are designed to be installed in a standard 19-inch rack, which should provide adequate air-flow to cool down the gateway, and should be firm enough to support the weight of the gateway. It is also recommended the rack is earth grounded properly. PSTN Line If the gateway is equipped with FXO interface, be sure to subscribe PSTN lines from local telephone company and activate the lines prior to the installation. IP Network The gateway is connected to IP network through its 10/100 base-t Ethernet port and communicate with other equipments through the network. Inspect IP network on the site, including router, switch, cable wiring and etc, and make sure they are ready for the gateway. AC Power Outlets The gateway needs AC power supply, and sometimes the power is provided through a power strip with extension cord. Verify that each socket outlet on the power strip is equipped with protective earth contact and the protective action is not negated by using extension power cord. 1.3 Opening Inspection After the completion of installation preparation, you should open the box for inspection.
