4 FlexiPacket MultiRadio replacement

4.1 Double cable configurationThis paragraph gives the procedure to follow when having to replace the faulty Flexi-

Packet MultiRadio from the supporting framework fastened to the pole (independent

antenna configuration) or from the antenna (integrated antenna configuration).

Steps

1 Power off the FlexiPacket MultiRadio.

2 Pull out the Ethernet cable and the Power Supply cable, if any.

3 Disconnect the ground.

4 Disconnect the RF waveguide.

5 Unhook the four hooks on the FlexiPacket MultiRadio.

6 Lift the FlexiPacket MultiRadio, so as to free it from the hooks on the support, and

remove it.

7 Install the FlexiPacket MultiRadio spare part.

8 Hook the four hooks.

9 Connect the RF waveguide.

1 Connect the ground.

11 Connect the Ethernet cable and the Power supply cable, if any.

12

Power on the FlexiPacket MultiRadio.13 Connect the PC.

14 Configure the FlexiPacket MultiRadio with the same configuration and same licence

of the faulty FlexiPacket MultiRadio (refer to the Commission document). To restore

the license with CLicS after the replacement of a faulty FlexiPacket MultiRadio refer

to paragraph 8.2 of the Operate and Maintain document).

t If a backup file has been saved, this file can be used to restore the configuration(refer to the Operate and Maintain document).

15 Enter menu Alarmsand verify that no alarm is active.

tIn case of a failed FlexiPacket MultiRadio connected to a FlexiHopper antenna followthe steps:

Remove the assembly FlexiPacket MultiRadio + FlexiHopper Adapter.

Disconnect the FlexiHopper Adapter from the FlexiPacket MultiRadio.

Take a spare FlexiPacket MultiRadio and install on it the previously disinstalled Flex-

iHopper Adapter.

Install on the FlexiHopper Antenna the assembly.

Sent to the repair center only the FlexiPacket MultiRadio.
