Troubleshooting (Fault Finding); Test Link End Hardware - Motorola PTP 600 Series User Manual

11 Troubleshooting (Fault Finding)

Perform troubleshooting (fault finding) procedures either on a newly installed link, or on an
operational link if communication is lost:
1. Test the hardware at one end of the link, as described in Section 11.1 "Test Link End
Hardware".
2. Test the hardware at the other end of the link, as described in Section 11.1 "Test Link
End Hardware".
3. Test the radio link, as described in Section 11.2 "Test Radio Link".

11.1 Test Link End Hardware

When the link end hardware (PIDU, LPU, ODU and cabling) has been installed, start it by
following this procedure:
1. Connect the RJ45 from the ODU (or LPU if fitted) to the PIDU and apply mains or
battery power to the PIDU. The green Power LED should illuminate continuously.
2. After 45 seconds, the yellow Ethernet LED should be observed starting with 10 slow
flashes.
3. Connect the RJ45 from the LAN port of the PIDU to the network. The yellow Ethernet
LED should blink randomly as traffic passes through.
If the Power and Ethernet LEDs do not illuminate correctly, test the link end as described in
the flowchart (Figure 130).
NOTE: The flowchart contains references to the detailed test procedures 11.1.1 to 11.1.7.
