This system is designed to be operated indoors as a fixed system device and must be located either on or near the ceiling away from the user. It must be mounted in a manner to ensure that all users and bystanders and users are kept a minimum of 20cm away from antennas at all times. Do not touch or move the antenna(s) while the unit is transmitting or receiving. Do not hold any component containing a radio such that the antenna is very close to or touching any exposed parts of the body, especially the face or eyes while transmitting. In most parts of the world, regulatory approval(s) are needed before the nanoBTS is operated. Do not connect any device other than the nanoBTS to any RJ45 socket that has been enabled for nanoBTS connection (i.e. 48Vdc operation).

If evidence of condensation is present do not apply power to the nanoBTS. The cabling to the nanoBTS and power supply is to run indoors only. The nanoBTS must only be powered using a PSU supplied by ip.access; the approved part is APC model PSU109 with UL file number E231617. PSUs supplied by ip.access must not be used for powering any other equipment. The external antenna ports are not covered by this products UL approval. 1.3 Regulatory Information For all regulatory information please see CENG0133 Ref{1}. 1.4 Unpacking Unpack nanoBTS and check to see that the unit has not been damaged in transit. Any damaged units should be returned to your supplier. Figure 1 - Unpacking the nanoBTS

NOTE: The RF feeder cable must not be bent as this may result in a degraded performance. Remove the plastic covers by removing the top and bottom plates from both ends of the nanoBTS. Lever gently apart with screwdriver in notch.

Refer to CENG0033 for details of the power supply connections. 1.7.2 Timing Interface Bus (TIB) – Multi-TRX only The Timing Interface Bus (TIB) is used to provide clock and signaling between the nanoBTS when operating in a Multi-TRX configuration. The TIB OUT from the Master TRX must be connected to the TIB IN of the slave TRX. This in turn has its TIB OUT connected to the next TRX in the chain. See Figure 9 - TIB Connections Figure 9 - TIB Connections

To fit the earth strap, remove the nanoBTS from the mounting plate Using the screw provided, screw the Earth Strap to the stud on the rear of the nanoBTS, see Figure 10 - Earth Stud. Earth Stud Figure 10 - Earth Stud Connect the other end of the Earth lead to the next nanoBTS Earth stud in the chain.

The network wiring must be complete before the nanoBTS can be installed and commissioned. The nanoBTS should be placed on a wall at or above head height or on a ceiling. Remove the nanoBTS from the bracket by sliding the removal tool over the central fin between the bracket and the body of the unit to disengage the locking spring, slide bracket to separate it from the main body of the unit. The tool may be inserted from the top or bottom of the nanoBTS Figure 11 - nanoBTS Bracket Removal Position the bracket on the wall and mark the position of the four screw holes. The top of the bracket MUST be positioned uppermost. Ensure that the bracket is level and sufficient clearance is maintained to allow the unit to be located on the bracket (at least 80mm from the bracket to the top of wall and 120mm from the side of the bracket to a side wall). See the diagram below, Figure 12 - Fixing the wall bracket. 80mm min120mm min Figure 12 - Fixing the wall bracket Drill the four holes in the positions marked previously and insert wall plugs (if required) and fix the mounting bracket securely to the wall. The bracket is designed to allow the nanoBTS unit to be mounted with the connections at the bottom of the unit. Slide the nanoBTS onto the bracket and ensure that the retaining spring engages into the indent at the rear of the unit.

On a sloping surface the top of the bracket MUST be uppermost. Once the unit has been attached to the bracket the outer cover MUST be removed to expose the cooling vanes, as shown in Figure 14 - Ceiling Mounted nanoBTS Figure 14 - Ceiling Mounted nanoBTS 1.8.1 Mounting Multi-TRX nanoBTS When the nanoBTS are to be installed in a Multi-TRX configuration, then each TRX should be installed in a similar orientation but not closer than 30cm to each other. A further specific constraint is that the TIB cables must be <1.5m and a 1.5mm2 Earth cable must also be connected between each TRX with a length not exceeding that of the TIB cable.

It is recommended that during installation an initial, local calibration is made following a powered on time of > 10 minutes followed by a final operational calibration after 24 hours power on time. NOTE: If the nanoBTS is used in a Multi-TRX configuration, then the TIB OUT must be disconnected from each nanoBTS in the chain prior to calibration and reconnected afterwards. • Using BTSInstaller, select the nanoBTS that is to be calibrated and then click on the “Listen” button in the “BTS Status” pane. • Select the frequency band to match that of the nanoBTS to be installed. • Click on the “Connect” button, this will cause the nanoBTS TRX to power up. The status LED will flash green when completed. • Click on the “Channel Usage” tab and then click on the “Start Test” button. • When completed click on the “BCCH Channel Usage” tab and then click on the “Start Test” button. • When completed, click on the “Frequency Synchronisation” tab. • Select “Configure Test” • Select the “Freq Sync Options” tab and then click on the “Apply Frequency Synch Options” and change the Option to “Adjust The Clock To Correct The Reported Errors” then click “OK” • Click on the “Start Test” button. Once the test completes then the calibration is completed and the procedure should be repeated for all installed nanoBTS before reconnecting the TIB cables. Following the 24-hour period, the Frequency Calibration procedure should be performed as per the Operations procedure – Ref {2}
