Installing a Circuit Card (MAP/5PV4)


Damage from electrostatic discharge is possible. See Protecting Against ESD Damage for more information.

For the location of the circuit card cage cover and the ISA and PCI circuit card slots, see Internal Layout (MAP/5PV4) and Motherboard Connections (MAP/5PV4 Only). See Platform Circuit Card Assignments (MAP/5PV4) for information about circuit card slot assignments.

To install a circuit card:

  1. Verify that the replacement equipment is on site and appears to be in usable condition, with no obvious shipping damage.
  2. If the system is in service, perform the following Steps a and b:
    1. Stop the voice system.
    2. Shut down the system.
  3. Remove the incoming power.
  4. Remove the dress cover.
  5. Remove the new circuit card from its ESD protective wrapping.
  6. Verify the circuit card switch settings and jumper settings. If you are replacing a defective circuit card, ensure address switches and jumpers are set to match the old circuit card.

    Note: See Circuit Cards for instructions for each type of circuit card being installed, and then continue with Step 7.

  7. Holding the circuit card by its upper corners, carefully slide the circuit card's edge connector into the slot and the circuit card's slot retainer bracket into the slot guide. Apply pressure to only the top of the circuit card, until the edge connector is firmly seated in the slot connector.

    8. Note: It is very important that you properly seat the circuit card in the slot. If the circuit card is not properly seated, the system will not recognize it.

  8. Secure the circuit card into position by replacing and tightening the slot faceplate retaining screw.
  9. Attach all cables to the new circuit card. Make sure these cables are attached to their proper terminations.
  10. Attach all cables that were removed from other circuit cards, if necessary. Make sure these cables are attached to their proper terminations.
  11. Replace the card cage cover.
  12. Replace the dress cover.
  13. Apply power to the system.

Removing the Hard Disk Drive (MAP/5PV4)


Damage from electrostatic discharge is possible. See Protecting Against ESD Damage for more information.

The system contains one hard disk drive, which is located in bay 7. For the location of bay 7 and the peripheral frame, see Internal Layout (MAP/5PV4), Peripheral Frame Location (MAP/5PV4), and Peripheral Frame Removed (MAP/5PV4).

To remove the hard disk drive:

  1. Verify that the replacement equipment is on site and appears to be in usable condition, with no obvious shipping damage.
  2. If the system is in service, perform the following Steps a and b:
    1. Stop the voice system.
    2. Shut down the system.
  3. Remove the incoming power.
  4. Remove the dress cover.
  5. Remove the diskette cable from the back of the diskette drive.
  6. Remove the power cable from the back of the diskette drive.
  7. Remove flat ribbon cable 1 from the back of the hard disk drive. See Flat Ribbon Cable 1 (MAP/5PV4).
  8. Remove the power cable from the back of the hard disk drive.
  9. Locate the peripheral frame and the peripheral frame thumb-tab lock. See Peripheral Frame Location (MAP/5PV4) for more information.
  10. Remove the peripheral frame from the chassis. See Removing the Peripheral Frame (MAP/5PV4) for instructions about how to remove the peripheral frame.
  11. Locate the screws that secure the hard disk drive to the peripheral frame.

    Note: Pay close attention to the location of the screws in both the peripheral frame and the hard disk drive.

  12. Holding the back of the hard disk drive, remove these screws.
  13. Place the hard disk drive assembly, with the printed circuit board facing up, on an ESD-protected surface.
  14. Continue with the next procedure, Installing the Hard Disk Drive (MAP/5PV4).

Installing the Hard Disk Drive (MAP/5PV4)


Damage from electrostatic discharge is possible. See Protecting Against ESD Damage for more information.

The system contains one hard disk drive, which is located in bay 7. For the location of bay 7 and the peripheral frame, see Internal Layout (MAP/5PV4), Peripheral Frame Location (MAP/5PV4), and Peripheral Frame Removed (MAP/5PV4).

 

To install the hard disk drive:

  1. Remove the new hard disk drive from its ESD-protective wrapping.
  2. Set the jumpers. See Hard Disk Drive Jumper Settings (MAP/5PV4) for information about the jumper settings.
  3. Place the hard disk drive into bay 7. Make sure you correctly align the screw holes.
  4. Use the four screws that you removed in Step�12 of Removing the Hard Disk Drive (MAP/5PV4) to secure the hard disk drive to the peripheral frame. See Peripheral Frame Removed (MAP/5PV4) for more information.
  5. Place the front of the peripheral frame into the system. Make sure the guides at the top of the peripheral frame are aligned with the guides on the bottom of the upper peripheral bracket. Peripheral Frame Removed (MAP/5PV4) for the location of the peripheral frame guides.
  6. Slide the peripheral frame towards the front of the chassis. Make sure the peripheral frame locks into place.
  7. Attach the power cable to the hard disk drive.
  8. Attach flat ribbon cable 1 to the hard disk drive. See Flat Ribbon Cable 1 (MAP/5PV4).
  9. Attach the diskette cable to the back of the diskette drive.
  10. Attach the power cable to the back of the diskette drive.
  11. Replace the dress cover.
  12. Apply power to the system.
