5. INSTALLATION
5.1 Installation Record
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 Axell Wireless Ltd. should these figures
be needed for future reference or diagnosis.
5.2 General Remarks
The size and weight of the equipment racks mean that they represent a significant topple hazard
unless they are bolted to the floor though the mounting holes in the base of the unit. In the interests of
safety this should be done before any electrical, RF, or optical connections are made.
The equipment 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 rack.
5.3 Electrical Connections
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.
Ensure that connections are kept clean and are fully tightened.
5.4 RF Connections
All RF connections are made to the cable termination, located on the bulkhead at the rear of the
equipment at floor level. 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.
5.5 Optical Connections
The optical input and output ports will be located on the appropriate E/O shelf as shown in the rack
layout drawing and the system layout drawing. The ports are supplied with a green plastic cover,
which must be removed prior to the connection of the fibre cable. Ensure that transmitter and receiver
fibre cable are identified to prevent misconnection. At the master site, the fibre transmitters are in the
downlink path with the receivers in the uplink. At the remote sites the fibre transmitters are in the
uplink with the receivers in the downlink.
Ensure that connections are kept clean and are fully tightened.
