Power consumption depends on the equipment connected to the FTFAsub-module.

2.3 FPFA and FPFB interfaces

Power is distributed from Flexi Power Distribution and Fuses (FPFA andFPFB) 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, whichgives more power feeding capacity to RF Modules. The FPFB iscompatible with both System Module releases.

The FPFB does not have any circuit breakers but instead electrical fusesand a dedicated power switch for the System Module. The fuse rates forthe FPFA are:

. A.101: RF1-3 20.0A, EXT 25.0A

. A.102 or later: RF1-3 20.0A, EXT 25.0A (System Module suppliedvia 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.

DN7084495Issue 7-3 en30/04/2009



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 forinput connections of the FPFA/B and when connecting power to theSystem Extension Module.

The multibeam connectors on the front panel must not be used as input tothe FPFA/B. The multibeam connectors are not hot-plug connectors. Thepower must be switched off via the on/off switch on the FPFA/B front panelwhen connecting or disconnecting the RF or System Extension Module tothe 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 asinstructed.

FPFA version A101

Extension module power supply comes through the circuit breaker andextension module power can be switched off via the circuit breaker. Thismust be done if the extension module is connected to the System Moduleto avoid hot-plug connection. This also required when disconnecting fromthe System Module.

When pulling the EXT circuit breaker switch to off position, switch off thepower supply to the extension module. Power feed to the System Moduleis still on.

FPFA version A102, A103 or later

FPFA versions A102, A103 or later have a common power supply via thesame circuit breaker for the System Module and the System ExtensionModule. This means that the same circuit breaker switch can be used toswitch on and off the power to the System Module and the SystemExtension Module.

Note

The System Module and extension modules are reset by pulling theEXT circuit breaker on/off switch on the front panel.

DN7084495Issue 7-3 en30/04/2009



When connecting the extension module to the System Module, switch offthe circuit breaker 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 theSystem Module.

6 System Module as an extension module

The System Module can be used as a System Extension Module operatingin a baseband extension mode to add channel capacity. In this case, it isconnected to the System Module by connecting two optical cables and aDC cable. These items are provided with Flexi System Extension Kit(FSKA).

When the System Module is used as a System Extension Moduleoperating in a baseband extension mode, a transmission sub-module isnot installed. Instead, a dummy transmission sub-module is installed toprovide IP protection. This item is also included in Flexi System ExtensionKit (FSKA).

When the System Module is used as a System Extension Moduleoperating in a baseband extension mode, the only connectors that can beused are DC input and optical interfaces from the System Module.Synchronisation is provided by the System Module. For installationinstructions, see section Installing System Extension Module in theInstalling Flexi WCDMA BTS Optional Items document. Forcommissioning instructions, see the Commissioning Flexi WCDMA BTSdocument.

When integrating the System Extension Module to Flexi WCDMA BTS, nocommissioning is required. Once the System Extension Module has beenconnected to the System Module and powered up, the auto detectionfunctions of Flexi WCDMA BTS detect the System Extension Module andconnect the System Extension Module to the normal operation of the BTS.As for software requirements, the auto detection requires that WN3.3 orlater BTS SW exists and is active both in the System Module and SystemExtension Module to be connected to. However, support for the FSMC andFSMD is introduced in WN5.0

1) Testclk_out (pin 11) is disabled by default, until commanded on via BTS manager.

Signal descriptions:

. 2M_out: 2.048 MHz clock reference output (ITU-T G.703/chapter 13). The signal comes from the Flexi transport part, which is locked

(PLL) to the Iub interface.. The signal in MDR14 is asymmetric: connect the core of the

coaxial cable to pin 7 and cable shield to GND (e.g. pin 14).

. Testclk_out: 10MHz system clock (LVTTL). The signal comes from BTS OCXO which is used for air I/F

generation => reference 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 11 and cable shield to GND (e.g. pin 10)

. GND: signal ground, for asymmetric signals

. PPS_out: Pulse Per Second (1Hz) frequency and time reference(electrically RS-485)

. GPStime_out: GPS time reference (electrically RS-485)
