RAM2241 RU User Manual Version 0.2（2012-06-18） General safety precautions All safety attention to realize As the guarantee person and equipment safety, once operating the installation, operation and maintenance of the equipment, please follow the equipment identification and manual that all of the safety precautions. In the manual, "note", "warning" and "dangerous" matters, doesn't mean that all security matters should abide by, just as all safety precautions supplement.
RAM2241 RU User Manual Personal safety Banned in the thunderstorm weather to operate the equipment and cables. Open hole look straight into the optical fiber, in order to prevent the laser burn eyes. If fire, should be evacuated from the building or equipment area, and press the fire alarm, or dial the fire alarm call. In any case, it is strictly prohibited to once again into the burning building.
RAM2241 RU User Manual alternating current operation, and equipment installation , or you will have life risks. Big leakage current Before turn on the power, the equipment must grounding, otherwise you will endanger personal and equipment safety. Power supply cord Banned connected, disconnected the power cord when charging the equipment. The power cord in the moment of contact with conductor core will produce electric arc or edm, may lead to fire or eye injuries.
RAM2241 RU User Manual Before the light source has been shut down, banned to look directly into the end of any optical fiber. An optical power meter should be used to verify active fibers. A protective cap hood must be immediately placed over any fiber connector to avoid the potential of dangerous amounts of radiation exposure. Fiber operation Please follow the optical fiber operation requirements: Only properly trained personnel to do cutting and welding optical fiber operation.
RAM2241 RU User Manual When equipment installation, please clearly marked the number and name of fiber link to avoid the fiber connection error. Fiber link error will lead to U-DAS2200 system does not work normally. In U-DAS2200 system, up link and down link are independent optical transmissions. Wrong connection for UL and DL, or wrong connections for different ports from higher level can cause equipments do not work normally.
RAM2241 RU User Manual Inside MU and EU, lower power supply of AC/DC is assembled, MU and EU cannot offer of lower equipments remote power supply by themselves. But MU and EU both have the spreader plate which divides into 8 roads input DC power supply for RUs. Reboot equipment The ship type switch of MU front panel is for AC power input and backup battery hige switch. No DC power switches for MU. DC power hige control is controlled by PSU. If need to reboot MU, there are three options.

RAM2241 RU User Manual 1 Overview 1.1 U-DAS2200 system U-DAS2200 system is a solution for transmission and distribution of wireless signals solutions, is a kind of intelligent and active integrated antenna distribution system. Working band can cover from 680 MHz to 2200 MHz for all of the cellular mobile communication frequency. Meet from simple to complex all kinds of indoor wireless access network requirements.
RAM2241 RU User Manual As shown in Figure 1-1 shows, U-DAS2200 system the basic equipments: the main unit (MU), expansion unit (EU), remote unit (RU) composition. When the system working in many business state, it needs to increase the wireless access unit (WAU). The wireless access unit (WAU) combines more signals from the base station, and apply the RF signal to master unit (MU). Master unit (MU) will convert the RF signals to light signals, and expanded to 8ways to lower equipment.

RAM2241 RU User Manuel 3.2 Equipment Connection 1）RF cable connection Figure 3-4 RAM2241 RU power supply connection 2）Fiber connection Figure 3-5 RAM2241 RU fiber connection Take down the dust cap of the equipment, and properly kept, has been used next time. On the positive direction, guarantee the connector center in the same axis, bolt and card slot in the same direction, such as shown in Figure 3-5.
RAM2241 RU User Manuel Figure 3-6 RU power line cable connection Sick the RJ45 connector to the internet socket, the key to the neck such as shown in Figure 3-6 ,nip the end of the plug and push slightly to the socket.When it clicks,they are con nected in place and the RJ45 connector wouldn't get loose.
RAM2241 RU User Manuel Note, RJ45 joint should adopt standard of T568A or T568B line sequence. If line sequence is wrong then may cause permanent damage to the device.
RAM2241 RU User Manuel 4 U-DAS2200 Opening 4.1 The preparing work before opening 4.1.1 The matching of the access power of signal Design principle: According to insertion loss of different wireless access unit and the output power of different base stations, we calculated the value of the attenuation, make after combine the all the signal together then the input power into the DL of main unit is 0 dBm.
RAM2241 RU User Manuel In the second step, according to the actual configuration business quantity, estimate power of every business need to infuse the MU. If it is 4-band system, the input power will be forced into each MU adjustment for-6 dBm as far as possible. 3-band system, each power will be forced into MU is adjustment for-5 dBm. 2-band system, each power will be forced into MU adjustment for-3 dBm. So the total power is easy to control requirements in range.
RAM2241 RU User Manuel In U-DAS，MU is in 0 level，no need to configured。The equipment under the MU is level-1 Expansion Unit，so that the first address is“1”for this EU。If a EU is under the level-1 EU, then this EU will be level-2, and the first address is configured to “2”。 Wrong coding the address of Expansion Unit will cause the higher equipment can not find it, can’t do the monitor control.
RAM2241 RU User Manuel Figure4-3 Address configuration As Figure4-3 shows EU01 is bellow MU，in level 1，so the left address is“1”，E01 is connected to the port1 of Main Unit， so the right address of EU01 is“2”。EU02 is bellow EU01，in lever-2，and EU02 is connected to the port 6 of EU01，so the address configure on EU02 is“2”，“6”。 U-DAS2200 support two levels of EU currently. 4.
RAM2241 RU User Manuel The most troubles in the opening U-DAS2200 are wrong connections in the link engineering, wrong address configuration of the equipments and big loss in fiber link engineering. Check the equipments based on the checking list before power up the equipments. Table 4-1 Main Unit Check List Table No. Check Items Check Requirement 1 MU Installation environment See 3.1 2 Grounding Line See 3.2 3 Fiber port connection See 3.2 4 CAT-5 Connection See 3.
RAM2241 RU User Manuel 4.2.1 Equipment Power up and Debug The power up flow is from lower level of equipments to higher level of equipments.(RU-EU-EU-MU) Before power up the equipments, we need to check the installation of every equipment, the fiber link labels, and the configuration of EUs by using the Design documents The restart the “reset” on MU can refresh the system topology.
RAM2241 RU User Manuel The ship type switch of MU front panel is for AC power input and backup battery hige switch. No DC power switches for MU. DC power hige control is controlled by PSU. If need to reboot MU, there are three options. 1 Shut down AC, DC, power, and then open PSU, AC power. 2.Reset button on the panel.( only reboot the monitor module) 3.By OMT software to reboot. The ship type switch of EU front panel is for AC power input. No DC power switches for EU.
