    3. OPERATION

    This section provides instructions for operating the IDU. Included isinformation on the interface terminals, interface jacks, controls, indicators,test jacks, equipment start-up, and equipment shut-down.

    3.1 Interface Terminals and Jacks

    The IDU has interface terminals and jacks to interconnect data, alarm andIF signals with associated equipment. These interface terminals and jacksare located as shown in Fig. 3-1 and are used as described in Table 3-1.

    Caution: Do not connect between the NMS/RA terminals with theRS-485 cable, when PM CARD is mounted on the IDU, theprotocol is set to RS-232C and the back-to-back connectionbetween the NMS/RA terminal on the IDUs is performed.

    The setting of each item for the IDU is performed by the PC as follows:

    Caution: If login is not possible, check if settings of the

    communication format are proper.

    Caution: Do not turn on the power of the IDU leaving cableconnection between the PC and RA PORT of the IDU.

    Step Procedure

    4. MAINTENANCE

    This section provides instructions for periodic maintenance and correctivemaintenance of the IDU. Included is information on precautions, testequipment and accessories, periodic maintenance and correctivemaintenance.

    4.1 Precautions

    The following precautions must be carefully observed duringmaintenance.

    Danger: The 43 V DC power is superimposed on the centerconductor of the coaxial cable between the IDU and ODU.Connecting a measurement set may damage that set and

    touching the coaxial cable core may cause electrical shock.So, turn off the power switch on the IDU before

    disconnecting coaxial cable between the IDU and ODU.

    Caution: To protect the internal circuits against electrostaticdischarge, engineers are requested to wear a wrist band andconnect it to the frame ground terminal (FG) forElectrostatic Protection (ESP) before detaching the shieldcover (see Fig. 4-1).

    Caution: Do not turn on the power of the IDU leaving cableconnection between the PC and RA PORT of the IDU.

    Fig. 4-1 Location of the ESP Terminal.

    (a) Before beginning maintenance, notify the opposite station thatmaintenance is about to begin.

    (b) After equipment start-up, allow the equipment to warm up for at least30 minutes.

    (c) After completing the maintenance operation, restore all connectionsto normal.

    (d) During maintenance, the IDU is set to maintenance condition using aPC as follows:

    Connect the wrist strap.IDU(FG to be used as ESP)

    Note: The range of DC power input depends on system requirement.

    4.4 Corrective Maintenance

    Corrective maintenance in the field is described, and covers fault isolation,equipment replacement and alignment. When the equipment is faulty, itshould be replaced with a spare. Replacement for the IDU is at the

    equipment-level. During corrective maintenance, carefully observe theprecautions given in paragraph 4.1 until alignment is completed.
