6.6 – Replacement of the X-Pol RBS Replacement of an X-Pol RBS has no impact on alignment. To replace the X-Pol RBS: – disconnect the grounding cable (see Figure 31 – Grounding the outdoor equipment with the 9900UXI102 pole mounting), We have four cables behing X-Pol RBS and DBS: – two cables RS422 Data with pling LEMO: • two cables IF IF and DC cable for X-Pol RBS Tx/X-Pol RBS Rx, • one cable with reference frequency.
Note: NT unit cannot be replaced by another NT unit of a different type. If wanted, the services on this NT must be suppressed then created again when the NT has been declared and has been entered into the network. 6.8 – Malfunctions 6.8.1 – Malfunctions on installation The A7390 is a reliable and easy-to-install system. By following the procedures described in the documentation, no problem should occur.
7 – Changes of configuration 7.1 – Interventions required by system evolution Evolution of the transmission network may require changes being made to equipment configurations in order to meet new needs. The A7390 equipment has sufficient flexibility to satisfy these scalability requirements. Modifications can be carried out by changing the software configuration with or without modifying the hardware configuration of the equipment, as the case may be. The 7390 LT may itself be subject to changes.
Note: Change network interface 155 Mbit/s to 34 Mbit/s is not possible. 7.2 – Recommendations For carrying out work of any kind on boards (disassembly/assembly, configuration modification), the operator must be equipped with a grounding strap (e.g., a "Disposable Wrist Strap" 3M, reference 2209). THESE OPERATIONS ARE ONLY TO BE CARRIED OUT BY QUALIFIED TECHNICIANS AUTHORISED BY ALCATEL. UPDATE THE REFERENCE DOCUMENTS AND LABELS IN ORDER FOR THEM TO COMPLY WITH THE NEW CONFIGURATION.
