** Operational power consumption at room temperature
*** Module in idle state, fans off, +0°C
All above with nominal 48V voltage input.
For the fuse ratings of the FPFA/B outputs, see section FPFA and FPFB interfaces below.
For transmission sub-module power consumption figures, see section Power require-
ments of transmission sub-modules.
2.2 Power requirements of transmission sub-modules
The typical power consumption of the transmission sub-modules is described in the
table below.
Power consumption depends on the equipment connected to the FTFA sub-module.
2.3 FPFA and FPFB interfaces
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.
g If the total output power of an RF Module is more than 100W, the FPFB version of
the Flexi Power Distribution and Fuses module must be used with a rel. 1 System

Module. For example, in a 1+1+1 40W configuration the total output power is 120W
and therefore an FPFB is needed.
The FPFB does not have any circuit breakers but instead electrical fuses and a dedi-
cated power switch for the System Module. The fuse rates for the FPFA are:• A.101: RF1-3 20.0A, EXT 25.0A
• A.102 or later: RF1-3 20.0A, EXT 25.0A (System Module supplied via EXT circuit
breaker)
The fuse rates for the FPFB are:
• RF1-3 31.0A (+/-2A), EXT 25.0A (+/- 4.5A)
See the following figure for the location of the FPFA/B.
Figure 12 Location of the FPFA/B in the System Module
Inputs and outputs
A busbar input connector (with screw connection) must always be used for input con-
nections of the FPFA/B and when connecting power to the System Extension Module.
The multibeam connectors on the front panel must not be used as input to the FPFA/B.
The multibeam connectors are not hot-plug connectors. The power must be switched off
via the on/off switch on the FPFA/B front panel when connecting or disconnecting the
RF or System Extension Module to the FPFA/B.
There are two types of FPFAs available:
•
A101 version• A102, A103 or later
There are differences between these versions in the inner connections.

2.4 FPFA electrical connections
Note that there is a risk of short circuit. Connect the power cable as instructed.
FPFA version A101
Extension module power supply comes through the circuit breaker and extension
module power can be switched off via the circuit breaker. This must be done if the exten-
sion module is connected to the System Module to avoid hot-plug connection. This also
required when disconnecting from the System Module.
When pulling the EXT circuit breaker switch to off position, switch off the power supply
to the extension module. Power feed to the System Module is still on.
FPFA version A102, A103 or later
FPFA versions A102, A103 or later have a common power supply via the same circuit
breaker for the System Module and the System Extension Module. This means that the
same circuit breaker switch can be used to switch on and off the power to the System
Module and the System Extension Module.
g The System Module and extension modules are reset by pulling the EXT circuit
breaker on/off switch on the front panel.
When connecting the extension module to the System Module, switch off the circuitbreaker to avoid hot-plug connection to extension modules. After that, switch off the
System Module.
This is also required when disconnecting the extension module from the System
Module.

Flexi WCDMA BTS System Module Description System Module as an extension module
Id:0900d805805b6253
6 System Module as an extension moduleThe System Module can be used as a System Extension Module operating in a
baseband extension mode to add channel capacity. In this case, it is connected to the
System Module by connecting two optical cables and a DC cable. These items are
provided with Flexi System Extension Kit (FSKA).
When the System Module is used as a System Extension Module operating in a
baseband extension mode, a transmission sub-module is not installed. Instead, a
dummy transmission sub-module is installed to provide IP protection. This item is also
included in Flexi System Extension Kit (FSKA).
When the System Module is used as a System Extension Module operating in a
baseband extension mode, the only connectors that can be used are DC input and
optical interfaces from the System Module (with a few exceptions). Synchronisation is
provided by the System Module. For installation instructions, see section Installing
System Extension Module in the Installing Flexi WCDMA BTS Optional Itemsdocument.For commissioning instructions, see the Commissioning Flexi WCDMA BTS document.
When integrating the System Extension Module to Flexi WCDMA BTS, no commission-
ing is required. Once the System Extension Module has been connected to the System
Module and powered up, the auto detection functions of Flexi WCDMA BTS detect the
System Extension Module and connect the System Extension Module to the normal
operation of the BTS. As for software requirements, the auto detection requires that
WN3.3 or later BTS SW exists and is active both in the System Module and System
Extension Module to be connected to. However, support for the FSMC, FSMD and
FSME is introduced in WN5.0.

• Testclk_out: 10MHz system clock (LVTTL)
• The signal comes from BTS OCXO which is used for air I/F generation => refer-
ence for the RF measurement equipment.
• Note: the BTS OCXO is not in the PLL mode to the Iub, the locking is very loose
due to air I/F stability reasons.
• The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin
