TB9400 Installation and Operation ManualInstallation67 © Tait Limited April 2014 5Installation This chapter provides information on the site requirements for your TB9400 equipment and also describes how to install the base station in a standard 19 inch rack or cabinet. If this is your first time installing a TB9400 base station, we recommend that you read the entire chapter before beginning the actual installation. 68InstallationTB9400 Installation and Operation Manual © Tait Limited April 2014 5.1Before You Begin 5.1.1Equipment Security The security of your base station equipment is a high priority. If the site is not fully secure, the base station should at least be locked in a secure cabinet to prevent unauthorized access. 5.1.2Grounding and Lightning Protection Electrical GroundThe base station modules are grounded by physical contact between the module case and the subrack. To ensure a good ground connection you must tighten each module retaining clamp securely (refer to “Final Reassembly” on page 112 for the correct torque). A threaded grounding connector is provided on the rear of the subrack for connection to the site ground point (refer to “Connecting Up the Base Station” on page 88 for more details). Lightning GroundIt is extremely important for the security of the site and its equipment that you take adequate precautions against lightning strike. Because it is outside the scope of this manual to provide comprehensive information on this subject, we recommend that you conform to your country’s standards organization or regulatory body. 5.1.3Equipment Ventilation Always ensure there is adequate ventilation around the base station. NoticeDo not operate it in a sealed cabinet. You must keep the ambient temperature within the specified range, and we strongly rec- ommended that you ensure that the cooling airflow is not restricted. NoticeThe cooling fans are mounted on the front panel and will only operate when the panel is fitted correctly to the front of the subrack. To ensure adequate airflow through the base station, do not operate it for more than a few minutes with the front panel removed (e.g. for servicing purposes). 5.1.4Ambient Temperature Sensor The ambient temperature reading for the base station is provided by the temperature sensor located on the front panel circuit board. TB9400 Installation and Operation ManualInstallation69 © Tait Limited April 2014 5.1.5Cabinet and Rack Ventilation The cooling airflow for the base station enters through the front panel and exits at the rear of the subrack. For optimum thermal performance, the heated air that has passed through a base station must not be allowed to re- enter the air intakes on the front panel. Any space at the front of the cabinet not occupied by equipment should be covered by a blanking panel. Refer toFigure 5.1 on page 70. To allow enough cooling airflow through a cabinet-mounted base station, we recommend the following: ■an area of at least 23 in 2 (150 cm 2 ) of unrestricted ventilation slots or holes in front of the air intakes for the fans for each subrack; for example, thirty 0.25 x 3.3 in (6 x 85 mm) slots will allow the recommended airflow ■a vent in the top of the cabinet with an area of approximately 23 in 2 (150 cm 2 ) per subrack, or a similar area of ventilation per subrack at the rear of the cabinet behind each subrack ■a 2 U gap at the top of the cabinet. NoticeThe ventilation opening must be unrestricted. If the slots or holes are covered with a filter, mesh or grille, the open area must be increased to allow the same airflow as an unrestricted opening. The maximum ambient temperature entering the cabinet must not exceed + 140°F (+ 60°C). If you are installing multiple subracks in a cabinet, ensure that there will be enough cooling airflow through the cabinet after the equipment has been installed. For example, the recommended maximum number of subracks in a 38 U cabinet is five, as shown in Figure 5.1 on page 70. If the base station is installed in a rack or cabinet with other equipment with different ventilation requirements, we recommend that the base station be positioned below this equipment. Auxiliary Extractor Fans The base station does not require auxiliary extractor fans mounted in the top of the cabinet. If your cabinet is already fitted with fans, the following procedures apply: ■if there are six or more 4.75 in (12 cm) fans, each capable of extracting 94.2 ft 3 per minute (160 m 3 per hour), they must run continuously ■if there are fewer than six fans, you must remove them and ensure the vent in the top of the cabinet has an area of approximately 23 in 2 (150 cm 2 ) per subrack. If you have any other configuration, the performance of your system will depend on how closely you comply with the base station airflow requirements described above. 70InstallationTB9400 Installation and Operation Manual © Tait Limited April 2014 Figure 5.1Typical cabinet ventilation requirements b ventilation slots d airflow entry c blanking panels e airflow exit path 8in (20 cm) 2U ≥7in (≥17.5cm) side viewfront view top view c c d e b TB9400 Installation and Operation ManualInstallation71 © Tait Limited April 2014 5.2Unpacking and Moving the Subrack The subrack is packed in a strong corrugated cardboard carton with top and bottom foam cushions. To prevent personal injury and damage to the equipment, we recommend that two people unpack and move the subrack. To remove the subrack from the carton, follow the procedure illustrated in Figure 5.2. CautionA subrack complete with modules can weigh up to 46 lb (21 kg), or up to 53 lb (24 kg) complete with packaging. We recommend that you have another person help you unpack and move the equipment. The TBAA03-16 carrying handles will make it easier to move the equipment once it has been unpacked. If necessary, remove the modules from the subrack before moving it (refer to “Replacing Modules” on page 101). In all cases follow safe lifting practices. 1.Cut the tape securing…

Therefore the far-field calculation is appropriate and the minimum safe distance for the general public is 2.93m.
