Functional Description

DS200VPBLG1ADD is a VME Backplane Board developed by GE. It is a part of LCI (Load Commutated Inverter) series. It is designed to serve as the backplane for the J2 and J3 sections of the equipment’s card cage, while the J1 section uses a commercially available product. The board's multilayer architecture separates analog and digital power planes, ensuring minimal interference and reliable performance.

Key Features and Capabilities

• Multilayer Design: The VPBL board uses a multilayer design that keeps analog and digital power planes separate. This ensures optimal power delivery and signal integrity. Each slot is equipped with power distribution and bypass capacitors to maintain system stability.
• Section J2 Functionality: The J2 section supports several critical boards, including
  • Digital Signal Processor Control Board (DSPC): Occupies slot J1 with its daughterboards.
  • I/O Extender Board: Located in slot J3, adjacent to the DSPC.
  • Gate Distribution and Status Boards (FCGD): Installed in slots J5, J7, and J9.
  • Exciter Board: Positioned in slot J11.
  • Two spare slots in J12 and J13.
  • Each slot, except Slot 1, has a hardwired slot ID number at the P2 connector. Digital bus control signals, like the 16 MHz clock signal, terminate at the slot ends.
• Section J3 Functionality: The J3 section facilitates external connections that cannot fit on the board front due to space constraints. Current Transformers (CTs) and their burden resistors. Voltage Scaling Feedback Board connections for the FCGD boards. Additionally, this section handles power connections to the backplane and provides stab connectors for various grounding configurations.

Replacement Procedure

Step 1: Power Down
Ensure the system’s power supply is turned off completely to prevent any electrical hazards.

Step 2: Disconnect Cables
Carefully detach all cables, handling different connector types appropriately:

• Ribbon Cables (without pull tabs): Grasp the connector and gently pull it loose.
• Ribbon Cables (with pull tabs): Use the pull tabs to disconnect.
• Fiber-Optic Connectors: Press the latch on the connector and pull it gently, avoiding direct pulling on the fiber-optic cable.

Step 3: Remove Daughter Boards
Detach all daughter boards following their respective removal procedures as outlined in their documentation.

Step 4: Unscrew and Remove the VPBL Board
Remove the screws securing the VPBL board and carefully slide it out while keeping it level to avoid damage.

Step 5: Configure the New Board
Set all jumpers on the replacement board to match the jumper settings of the removed board.

Step 6: Install the New VPBL Board
Insert the new board into the slot and secure it using the screws provided.

Step 7: Reinstall Daughter Boards
Reconnect all daughter boards by following their specific installation guidelines.

Step 8: Reconnect Cables
Reconnect all cables, ensuring they are properly seated at both ends.
