Testing link end hardware
Testing link end hardware
This section describes how to test the link end hardware, either when it fails on
startup, or after a lightning strike.
Before testing link end hardware, confirm that all outdoor drop cables, that is those
that connect the ODU to equipment inside the building, are of the supported type, as
defined in
NOTE
Testing when PoE LEDs do not illuminate correctly
If the DATA & POWER OUT and DATA IN LEDs do not illuminate correctly during the
start-up sequence, test the link end as described in
the detailed test procedures that follow.
Testing after a lightning strike
If the installation has been struck by lightning, proceed as follows:
1
Test the link end as described in
detailed test procedures that follow.
Ensure that the PoE power supply is working and that the resistances
2
are correct as specified in
cable
3
If the ODU is not working, power off the ODU and LPU and return them
to Motorola.
4
If the ODU is working but there is suspicion of damage to the LPU, then
refer to
8-2
Installation inventories
These tests apply to installations that use the PoE power supply. If the PIDU
is installed instead of the PoE power supply, the test procedures will be
different.
