UNIVERSAL POWER-LINE CARRIER SYSTEM TYPE OPU-1 
WHOLE BAND QAM MODEM MBPU - Rev. 0  (July 2011) 

9/28

3 INSTALLATION 

This chapter describes the installation of the MBPU modem in the 6 s.u. shelf of the 

Universal Power-Line carrier terminal type OPU-1, together with the cabinet-mounted 

terminal block associated to the modem module. 

3.1 MODULE 

ARRANGEMENT 

The MBPU module can be installed in the last five positions of the 6 s.u. shelf, provided the 

said positions are not already occupied by other options. It must be kept in mind that the first 

shelf position corresponds, seen from the front, to module POWER SUPPLY (FAPU). 

The module must only be inserted when the power supply of the OPU-1 is not connected.

 

The MBPU module has two fixing screws, one at the top and one at the bottom of the 

front plate. 

To extract the module, turn the two fixing screws anti-clockwise as far as allowed. Then by 

means of the handles pull the module out of the shelf. 

Inserting the module in the shelf is achieved by carrying out the extraction process in 

reverse. Once the module has been inserted, the fixing screws must then be turned 

clockwise. 

3.2 TERMINAL 

BLOCK 

The terminal block associated to the MBPU module is called ZQBT. 

The block is fastened to the OPU-1 cabinet-mounted terminal block by means of screws. 

The connection between the block and the equipment is carried out by means of a cable. 

The ZQBT terminal block is made up of: 

  Four terminals that will allow a filter or an external equalizer to be inserted, provided 

jumpers J10 and J11 are in position B.
