Removing a TILx - HL module
To remove an i-link module, firstly switch off the TPRNx4 subrack which
houses the module.
Remove the fibers and the RF jumpers connected to the i-link module which is
going to be removed. Insert the caps on the optical ports which has just been
disconnected.
Unscrew the 4 screws at the corners of the i-link module which is going to
removed, and slowly remove the card.
Put the card in its safety box
TILx – HL start-up
Before both the master-side station and the slave-side station(s) are switched
on, make sure that:
all expected modules have been inserted into the Master Unit
the modules have been connected each other by RF jumpers, according to
what planned in the system design
the i-link master modules have been connected to the relevant slave side
modules through fiberoptics cables;
every TFLN master optical TRX has been connected to relevant remote
units
each remote unit has been connected to its coverage antennas
the remote supervision unit, if present, has been connected to the Master
Unit
both on the master-side and on slave-side stations, the different subracks
are connected each other via bus RS485
After that, remember that all remote units have to be switched on before the
master-side and the slave-side subracks. When all the remote units are on,
the different subracks (at master-side and slave-side) can be switched on.
Once all the active subracks have been switched on, the behaviour of the
different i-link modules can be summarized as follows:
o All the LEDs on the different i-link modules (both on master side and on
slave side) turn on for a couple of seconds;
o After that, all the green LEDs on the different modules remain ON (thus
indicating proper power supply), while the red LEDs switch off as soon as
the master-side and the slave-side detect each other;
o During normal working operations, the LEDs on the front panels of the
TILx modules should behave according to what described in table 5.13,
5.14, 5.15, 5.16;
o Once all the master-side and slave-side subracks have been switched
on, the system should begin to work correctly. Anyway, in order that the
i-link modules are recognized by the supervision management system, it
is necessary that the system carries out the discovery phase (please
refer to Supervision System Manual for more details). During this phase,
