Introduction
The modernization of the existing LTE network in central, north and east region is accomplished by the introduction of the new AirScale base stations. There are also sites where the existing FSMF will be used as the system module. FSMF is a common familiar hardware and is not included in the introduction part. The key component of the AirScale BTS is the AirScale system module which is described in the following sections.
1.1
Know your new AirScale System Module.

Nokia AirScale Capacity unit (ABIA) Nokia AirScale Capacity (ABIA) plug-in unit occupies half the width of a 19-inch subrack with an IP class of IP20. Weight: 2 kg. Nokia AirScale System Module Indoor can consist of up to six AirScale Capacity (ABIA). ABIA unit has six optical RF interfaces up to 6 Gbps OBSAI or 9.8 Gbps RI. IQ compression is ed with three RI links.
Nokia AirScale System Module installation and HW replacement Like other Flexi Multiradio BTS modules, the AirScale System Module allows a variety of module and plug-in unit-based installation options including: • stacked upon each other without any cabinet or rack • cabinet or rack installation • mounted onto a wall It is possible to stack two indoor subracks on a plinth or on top of existing Flexi casing. In wall installation, two subracks can be installed on top of each other on the plinth. Fan Replacement
The fans of the AirScale SM can be serviced on the field. It is possible to replace the fans from the back of an installed and operating module if there is working space for that. It is also possible to remove the module and easily replace the fan if there is no working space in the back of the module. During the fan replacement when the system module is operational, heat can temporarily rise and cause performance degradation for the system module. Unit Replacement
In case of failure, on-site service is done by the replacement of the plug-in unit. All maintenance requires front and top access only (except the fan replacement). Front cabling is used and the connectors and all fixings are easily accessible. In case of AirScale system module swap, the configuration data must be ed again to the module, either automatically using the auto-connection and auto-configuration functionality, or manually.

The fans of the AirScale SM can be serviced on the field. It is possible to replace the fans from the back of an installed and operating module if there is working space for that. It is also possible to remove the module and easily replace the fan if there is no working space in the back of the module. During the fan replacement when the system module is operational, heat can temporarily rise and cause performance degradation for the system module. Unit Replacement
In case of failure, on-site service is done by the replacement of the plug-in unit. All maintenance requires front and top access only (except the fan replacement). Front cabling is used and the connectors and all fixings are easily accessible. In case of AirScale system module swap, the configuration data must be ed again to the module, either automatically using the auto-connection and auto-configuration functionality, or manually.

Task overview
The existing TDD eNB with FSMF (+2 FBBA) and 3 FZHA RFM will be replaced with Airscale (1AMIA+1ASIA+2ABIA), 3 FZHJ RFMs and FPFC/FPFI power modules. The optical interfaces will be 6Gbps OBSAI links. There will be 3 OBSAII interfaces per FZHJ RF Module. The eNB should be in FL17A 0.2 SW release**. 11.3
Installation of FPFC/ FPFI power module
The FPFC /FPFI should be installed inside the shelter, preferably near the AS system module. This FPFC (or FPFI) will be used to power up the whole TDD eNB (AS baseband + 3 RFMs) and the FDD AirScale baseband modules. The installation location of the FPFC (or FPFI) should be directly below the AS system module (no HW is supposed to be installed on top of the AMIA rack).
63A CB can also be used for indoor FPFC/FPFI. More details in section 2.2
** The TL17A 0.2 SW release is the latest one available as on 07-Jan-2018. This is subjected to change after the release of the new update.
