Strip the DC input cable for 16 mm.

The cable size range for the DC input cable is 6 to 25 mm2and the outer cable diameter

4 to 11 mm.

g If your DC input cable is coming from Flexi Power Module (FPMA) (cable code 995069),the pre-cut guide mark for cable stripping is at 11 mm. Make a new cut at 16 mm and

then strip the cable.

6.2 Installing Flexi Multiradio 10 BTS optional Transmission

Sub-Module (FTIF)

Purpose

Flexi Multiradio System Module core (FSMF/G) has an integrated Gigabit Ethernet andoptical Ethernet transport interface available on the front panel, however, if more or

other Ethernet interfaces are required then install an optional transmission sub-module

(FTIF). The sub-module is also mandatory in co-location cases when a backhaul con-

nection or synchronization is done through time-division multiplexing (TDM).

Before you start

The System Module has to be powered off before installing or replacing the transmission

sub-module.

If cable entries are installed, remove them.

Steps

Remove the FTIF dummy unit as follows:

Undo the screws holding the FSMx core in place.

Pull out the core.

Remove the four screws holding the FTIF dummy unit in place.

g Leave the other dummy units in place if you are not installing any other optional sub-modules.
