Installation RBS 6201
1.      Installing the Base Frame. Unpack the base frame. Position the base frame as specified in the floor plan in Site Installation Documentation. Mark the positions of the four holes, using the base frame as a template. To make it easier to orient the base frame, one side is marked FRONT. Drill the holes in the floor and insert expansion bolts into each hole. Position the base frame over the pilot holes and insert the bolts, together with washers, trough the adjustable feet and screw in the bolts a few truns by hand. Tighten each bolt to the recomended torque.
2.      Attaching the Cabinet to the Base Frame Position the cabinet correcly by aligning the two holes in the botto of the cabinet with the fixed points on the slider of the base frame.
3.      Grounding the Cabinet. Route the earth grounding cable from the site Main Earth Terminal (MET), to the cabinet earth grounding point, connect this point to local grounding point (varies, site dependant).
4.      Connecting the Power Supply. The RBS can be connected to different power supplies. Select the applicable situation and perform the procedure, the RBS can also be connected to battery backup.
·        A -48 V DC power supply is being used
·        A +24 V DC power supply is being used
·        An AC mains power supply is being used
For this case, RBS 6201 uses AC mains power supply. 3 phase wire connect to AC Connection until refer to following figure.
5.      Connecting the On –Site Transmission System. The external transmission cable are connected to the Digital Unit (DU). The cable connections depend on the transmission alternative chosen for the spesific site. The actual location of the positions indicated in the figurescan vary, either using ATM connections (E1/T1) or IP transport (RJ45-electrical/optical), booth connection towards TRM modules.
6.      Conection the RF Cables. Route the RF cables to the connectors of each RU. The RF B cable of each RU is routed on top of the RF A cable. Connect the RF cables to the connectors and tighten them to a torque of 25 Nm using a torque wrench and a 32 mm opend-ended head. Press each cable firmly into the gasket of the cable inlet. Check that each cable is as straight as possible and make any necessary adjustments. Ensure that the internal cables of the RU’s have not been accidentally loosened.
7.      Verifying RBS installation at Site. Verification must be performed to check the installation of the RBS cabinet before it is integrated with the radio network, according to installation (swap) checklist and Standard Installation Checklist, refer to FORM RBS 6000 Check List Indosat. The RBS cabinet has already been verified at the vactory.
8.      PoweringUp the RBS. Ensure that the RBS mains power is switched off before starting. Switch on the RBS main power. Switch on each output on PDU where a cable is connected by pressing the buttons marked 1 to 11 in the following oder: 7-9-1-2-3-4-5-6-8-10-11. Make sure that the yellow indicator is off on the PDU.
