  • Page 33: Installation Of The System

    Prior to the installation, the location where the exchange is to be mounted should be determined according to the criteria below: The wall on which the MS48IP exchange is to be mounted must be firm enough to carry the anchor plugs and it is supposed to have a smooth surface.

  • Page 34: Application

    APPLICATION Dimensions of the mounting template are the same as that of the MS48IP system; hence, it can be employed while choosing the location of the system and determining the spots to drill. The most appropriate location where the system is to be hanged can be determined by using that template.
  • Page 35 I N S T A L L I N G Insert the last screw into the third anchor plug through the hole that is on the lower left side of the motherboard and tighten it. In the meantime, it suffices to drive the screw deep enough to prevent the cabinet from moving up and down, and prevent its lower part from getting released from the wall.

  • Page 36: Mb48Ip Motherboard

    MB48IP MOTHERBOARD The MB48IP motherboard comes as mounted in the plastic cabinet of the exchange. The motherboard has been attached to the chassis by a screw and a grounding metal, and it has been fixed by plastic clicks. Figure - 16 There is normally no need to remove the motherboard from the cabinet.
  • Page 37 Figure - 17 Then, the screw that holds the motherboard and the ground bar are removed. At this stage, the lower part of the card is supposed to be taken out by pressing two of the plastic clicks that hold the card, which are at both sides of the card, outward from the card, but the card must not be pulled out, it is supposed to be removed by being pulled out beneath the fixed clicks that are on the upper side of the card, only after the clicks in the middle are released.

  • Page 38: Sps48 Power Supply Module

    In order to replace the card back into the cabinet, the procedure described above should be reversed. The most important point here is to make sure that the screw and the grounding metal have been actually attached after the plastic clicks have been fixed.
  • Page 39 Figure - 20 The empty space below the SPS48 card in the cabinet has been reserved for the battery that is attached to the system cabinet with a plastic clamp when necessary. There is normally no need to remove the SPS48 power supply from the cabinet. It may be necessary to remove it only in case of malfunction.
  • Page 40 Figure – 21 The cables that are connected to the SPS48 are detached from the corresponding connectors. The two screws that hold the SPS48 must be removed and then the card is supposed to be taken out by loosening the plastic clicks outward the card. In order to replace the card back into the cabinet, the procedure that has just been described should be reversed.

  • Page 41: Battery Connection

    BATTERY CONNECTION Cables that are to be attached to the pole contacts of the battery that has been placed in the appropriate location in the plastic cabinet are available that are necessary for connecting the SPS48 to a battery. One of those cables comes from the battery connector that is on the SPS48, and the other from the battery switch.

    INSTALLING THE DSP EXPANSION MODULE: One of the 4 channel or 8 channel DSP expansion cards can be installed to the SO- DIMM connector on the EXP48IP VoIP module. Both type expansion modules have the same physical structures, therefore the installation details are the same. The DSP expansion board is installed on the SO-DIMM connector by placing the pin side of the card in the slot gently as it has 45 degrees horizontally with the mainboard (1) and then pressing the card downwards to make it parallel with the mainboard and...

  • Page 48: Grounding Information

    GROUNDING INFORMATION Grounding should be made in order to weaken the effects of thunderbolts that might strike through the telephone lines and to prevent reception of undesired inbound signals due to similar reasons. Besides, grounding is also useful for eliminating noise that might be induced on the system due to environmental effects.
  • Page 49 Since the cabinet of the MS48IP exchange is made of plastic, a special design has been created in order to distribute grounding within the system. The grounding cable is connected to the ground distribution point that is on the exchange. The grounding...

  • Page 50: Other Connections

    OTHER CONNECTIONS EXTERNAL MUSIC SOURCE CONNECTION An external music source (tape or CD player, radio) can be employed as a source for “Background Music” and “Music On Hold” in the system. In order to connect the source, wires from the headset output of the music source are connected to the 2-pin music connector that is on the upper left corner of the MB48IP motherboard.

  • Page 51: Cabling

    CABLING The design of the plastic cabinet of the MS48IP exchange has details that allow exchange cabling to be performed properly. Extension and line cables can be tied to the projections at the lower part of the cabinet by cable ties, after they have been attached to corresponding connectors.
