6 System Installation

6.2 Replacement or Installation of a Hot-pluggable IMS Module

If the system is supplied with an antenna and antenna cable, it is advisable to first mount the antenna in a
suitable location (see chapter Antenna Mounting) and lay the antenna cable.

Please use a Torx screwdriver (T8 x 60) for removal and installation of the module.

1.

Follow the safety instructions at the beginning
of this manual!

2.

Remove the two marked Torx screws from the
module holder plate or the cover plate of
the empty slot.

3.

Note when removing!

Pull the module carefully out of the guide
rail. Note that the module is firmly anchored
in the connector block of the housing. You need
a certain amount of force to release the module
from this link. Once the connection to the
connector block of the system’s backplane is
loosened, the module can be easily pulled out.

4.

Note during installation!

Please ensure that the module is correctly inserted into the
two guide rails of the system housing as otherwise damage to the module and the housing could be caused.
Make sure that the module is securely locked into the connector block before you fasten the two screws.

5.

Now you can put the installed module into operation.
