With Nokia BTS Manager, right-click the BCF object in the Equipment
View window and carry out a BCF Object Reset, or, if locked from the
BSC/NMS, request an unlock from the BSC/NMS (the BCF reset is
automatic in this case).
Connect your Nokia BTS Manager PC to the LMP connector on the
interface unit.
Block the BCF locally with Nokia BTS Manager, or request a BCF lock
from the BSC/NMS.
If the manager connection can still be established, open Traffic Manager
from the Transmission menu and export the TS allocation information to
your PC's hard disk.
Open the cable entry block.
Make a note of the TRX cabling.
Disconnect the TRX cabling.
Open the TRX retaining screws with a Torx T10 driver. Loosen the screws
enough to remove the unit, but leave them engaged in the threads to allow
easy refitting.
Remove the TRX.
Unpack a new TRX.
Insert the new uncommissioned TRX into the master TRX slot (slot 1).
Tighten the TRX retaining screws to 1.5 Nm (1.11 lb ft) with a Torx T10
driver.
