  • Page 37: Electrostatic Discharge(Esd) Considerations

    363-206-204 About This Document Electrostatic Discharge(ESD) Considerations CAUTION: Industry experience has shown that all integrated circuit packs can be dam- aged by static electricity that builds up on work surfaces and personnel. The static charges are produced by various charging effects of movement and contact with other objects.

  • Page 38: Figure 1. Static Control Wrist Strap

    363-206-204 About This Document To reduce the possibility of ESD damage, assemblies are equipped with grounding jacks to enable personnel to ground themselves using wrist straps (see Figure 1) while handling circuit packs or working on an assembly(s). The jacks for connection of wrist straps are located at the lower right-hand corner of each assembly and are labeled.

    DDM-2000 OC-3 Fan Shelf 4.0 inches If the DDM-2000 OC-3 is installed at the bottom of the bay frame, there should be an air gap of at least 1.25 inches below the DDM-2000 OC-3. A heat baffle or fan shelf is required between each pair of DDM-2000 OC-3 shelves as described below.

  • Page 79: Inspection

    Perform the following procedure before the DDM-2000 OC-3 Multiplexer installation or cable installation. Procedure 1. Verify that the frame or structure into which the DDM-2000 OC-3 will be installed is properly grounded. NOTE Each DDM-2000 OC-3 shelf, heat baffle, and fan shelf comes equipped with an installation kit, a pouch attached to the shelf (or baffle) containing the hardware required for mounting and grounding.

  • Page 80: Equipment Installation

    3. Inspect the DDM-2000 OC-3 shelf for visible damage, including bent or touching backplane pins. 4. Determine the type of bay frame the DDM-2000 OC-3 shelf will mount in. The DDM-2000 OC-3 shelf side mounting brackets may have to be moved, according to bay type.

  • Page 88: Procedure

    Two feeders (A and B) are required from the battery distribution fuse board (BDFB) to the DDM-2000 OC-3 bay. The bay power cable is used to power up to six shelves and up to three fan shelves (refer to Table 2-5).
  • Page 89 363-206-204 Equipment and Rear Access Cable Installation 3. Connect a cable to the upper DDM-2000 OC-3 shelf at each break point. NOTE The remaining cable in the break point connects to a fan shelf (when pro- vided). NOTE If the bottom shelf position is not being equipped and a bay power cable assembly is being installed, locate the breakouts on the cable so that a connector will be available for future addition of the shelf.

  • Page 90: Office Alarm Cable Installation - Rear Access

    In all cases, and as a matter of good practice, suppression devices such as diodes or contact protection networks must be provided across any exter- nal relay coil being driven by the DDM-2000 OC-3 to limit transient voltages and currents.

  • Page 91: Procedure For Shelf 1

    Procedure for Shelf 1 NOTE Office alarms are cabled to shelf 1 (bottom DDM-2000 OC-3 shelf) in the bay. Office alarms for the other DDM-2000 OC-3 shelves in the bay are daisy-chained up the bay from shelf 1 (bottom shelf).

    DDM-2000 OC-3 Fan Shelf 4.0 inches If the DDM-2000 OC-3 is installed at the bottom of the bay frame, there should be an air gap of at least 1.25 inches below the DDM-2000 OC-3. A heat baffle or fan shelf is required between each pair of DDM-2000 OC-3 shelves.

  • Page 151: Inspection

    Perform the following procedure before the DDM-2000 OC-3 Multiplexer installation or cable installation. Procedure 1. Verify that the frame or structure into which the DDM-2000 OC-3 will be installed is properly grounded. NOTE Each DDM-2000 OC-3 shelf, heat baffle, and fan shelf (when provided) comes with an installation kit, a pouch attached to the shelf, baffle, or fan shelf, containing the hardware required for mounting and grounding.

    363-206-204 Release 7 Installation Tests services and EC-1 interfaces are provided and thus VT and STS-1 cross-connects are applicable. Due to the flexibility and complexity of cross-connect s it is strongly recommended to document the cross-connects of each site and have a compilation located at each site.
  • Page 291 363-206-204 Release 7 Installation Tests An EC-1 interface composed of DS1 services should be cross-connected at the VT level as opposed to the STS-1 level. Thus in the event of one VT (or more) failure the channel protection switch would occur. An EC-1 interface composed of DS3 services should be cross-connected at the STS-1 level.

    When a system sets a parallel telemetry point, it also sets its correspond- ing system identification (SID) point. The SID point that is set is the same as the DDM-2000 OC-3’s shelf number. For the following tests it should be verified that the appropriate SID point is set. Issue the command rtrv-ne (RETRIEVE NETWORK ELEMENT) to check the shelf number.

    363-206-204 Operational Tests Procedure With a Terminal Use the following procedure to verify parallel telemetry wiring by activating alarm points and have the maintenance center observe for their appearance or by checking for activation with a volt meter. NOTE This test can be terminated at any time with the CANcel or DELete key. 1.
