6. INSTALLATION
When this equipment is initially commissioned, please use the equipment set-up record sheet in
Appendix B. This will help both the installation personnel and AFL should these figures be needed for
future reference or diagnosis.
6.1 General Remarks
The equipment racks that these master site shelves will be fitted into must be located on a flat, level
surface that is made from a material suitable for bearing the weight of the rack assembly. If the
installer is in any doubt about the suitability of a site it is recommended that he consult with an
appropriately qualified Structural Engineer.
It is important in determining the location of the rack within the room that space is allowed for access
to the front and rear of the equipment. To enable maintenance to be carried out, the doors must be
able to fully open.
The location must be served with a duct to allow the entry of cables into the unit.
The mains power supply is connected to the terminal strip located on the bulkhead at the rear of the
equipment at floor level. It is recommended that the connection is made by a qualified electrician, who
must satisfy himself that the supply will be the correct voltage and of sufficient capacity.
All electrical and RF connection should be completed and checked prior to power being applied for
the first time.
6.2 RF Connections
Care must be taken to ensure that the correct connections are made with particular attention made to
the base station TX/RX ports.
In the event that the base transmitter is connected to the RX output of the rack, damage to the
equipment will be done if the base station transmitter is then keyed.
Ensure that connections are kept clean and are fully tightened.
6.3 Commissioning
Once all connections are made the equipment is ready for commissioning.
Using the system diagrams and the end-to-end test specification, the equipment should be tested to
ensure correct operation.
On initial power up the system alarm indicators on the front panels of the equipment should be
checked. A red LED illuminated indicates a fault in that particular tray that must be investigated before
proceeding with the commissioning. A green LED on each shelf illuminates, to indicate that the power
supply is connected to the shelf
In the event that any part of the system does not function correctly as expected, check all connections
to ensure that they are to the correct port, that the interconnecting cables are not faulty and that they
are tightened. The majority of commissioning difficulties arise from problems with the interconnecting
cables and connectors.
