System Module and RF module/RRH require 48v DC power supply.
In local installations, the System Module provides DC power supply to the Radio Modules.
In Feederless / Distributed Sites the DC power supply to Radio equipment may be provided by any other (48v) DC source.
For 24v DC environment there is a DC-DC converter 24v 48v available (FPDA).

Power is distributed from Flexi Power Distribution and Fuses (FPFA and FPFB) to the System Module. The FPFA is used with System Module rel. 1, whereas in System Module rel. 2 it is replaced with the FPFB, which gives more power feeding capacity to RF Modules. The FPFB is compatible with both System Module releases.

Functional description: FTLB supports following physical interfaces:
- 2 x electrical Gigabit Ethernet, RJ45 (10/100/1000Base-T)
- 1 x optical Gigabit Ethernet, via optional SFP (e.g. for 1000Base-SX/LX)
- 4 x E1/T1/JT1 symmetrical, RJ48 (coaxial E1 supported via baluns)
It provides HW supports for Ethernet features like:
- Dual Iub, Native Iub/IP
- Timing over Packet (ToP)
- Synchronous Ethernet (SE) slave functions
FTLB is prepared also for Synchronous Ethernet Regeneration. This allows to synchronize either a collocated BTS or even a chained BTS on another site via Synchronous Ethernet.
All three GE interfaces can be used simultaneously with basic Ethernet switching functionality (RAN1847 Basic Ethernet Switching).

The figure above shows fully equipped Flexi Power Module (FPMA) with AC/DC converters (FPAA) and Batteries (FPBA).
FPMA is the casing, AC and DC cable connector box and support frame for actual power sub-modules FPAA, FPBA and FPDA.
Flexi Power AC-DC Sub-Module (FPAA)
The main function of FPAA is to provide 48 V DC power from AC to be used by the BTS modules. FPMA can house from one to three AC/DC rectifiers. Output power of each AC-DC rectifier is 1 kW.
Flexi Power Battery Sub-Module (FPBA)
FPBA is a separate optional sub-module to be used together with AC-DC Module (FPAA). FPMA can house up to three Battery sub-modules.
Battery sub-module provides up to 10 minutes battery back-up time when the Flexi BTS site AC power mains is down. FPBA is maintenance free Lithium Ion battery bringing significant savings in operaover 10 years of Li-Ion battery life time.
