DIG2 GPU Replacement

Prerequisites

Overview

This procedure describes and illustrates the steps necessary to replace the Data Acquisition & Image Generation (DIG2) Computer GPU Card.

note:

Hardware Configuration control is critical for proper system operation. Mixing of different generations of GPU Cards may result in image quality issues! Example: DIG and VeRB Computers utilize NVidia GPU's. DIG2 and VeRB2 Computers utilize AMD GPU's. Like type GPU's (NVidia or AMD) must be installed in both the DIG and VeRB Computers in the same console. Mixing of first and second generations DIGs and VeRBs is not permitted.

1 Power-Off (Shut Down) the Console

Procedure

  1. Select one of the following methods to power off the Operator Console:

    • If applications are running, click the Shut Down icon and select Shut Down.

    • If applications are down, open a Unix Shell using the Toolchest. Type: {ctuser@hostname} halt. Press Enter.

    The Operator Console monitor will display a ‘System Halted’ message when it is acceptable to power off the Operator Console.

  2. Power OFF the Operator Console at the front panel switch. (See Figure 2.)

    Figure 2. Console Power Switch

  3. Perform prescribed Lockout/Tagout procedure. For added protection, disconnect the Twist-N-Lock Main Power Cable from rear of console.

2 Remove DIG2 Computer

Procedure

  1. Remove the front and rear Operator Console Covers per prescribed cover removal procedure.
  2. Remove the cable connections at the rear of the DIG2 Computer chassis.
    note:

    Verify that all cables are labeled and clearly marked. If necessary, add a label for clarity.

  3. Remove the power cord at the rear of the DIG2 Computer chassis.
  4. Remove the four (4) 5mm socket cap screws and washers from the front of the DIG2 Computer chassis, holding the chassis to the Operator Console rack.

    Figure 3. DIG2 Computer Mounting

  5. Slide the DIG2 Computer chassis forward (out the front of console) and set aside. See the Safety, Equipment Service - Console chapter of the service manual for additional information regarding Console Component Lifting.

3 Remove GPU Card from DIG2 Computer

Procedure

  1. At the rear of the DIG2 Computer Chassis, release the Chassis Cover Lock using a Phillips screwdriver. Back out lock screw at least two (2) full turns.

    Figure 4. DIG2 Computer Chassis Cover Lock

  2. Slide the Chassis Cover towards the front of the chassis and remove.
    note:

    You may need to tap on back upper edge of cover to release cover before sliding forward.

  3. Remove the Expansion Card Hold-down Clamp from DIG2 Computer Chassis.

    Figure 6. DIG2 Computer Expansion Card Hold-down Clamp Removal

  4. Disconnect the Power Supply Connector at the rear of the GPU Card.
  5. Remove the Phillips Screw holding the GPU Card in the DIG2 Computer chassis and carefully remove the card from the Systemboard.

4 Install Replacement GPU Card in DIG2 Computer

Procedure

  1. Carefully install the replacement GPU Card in the same location (slot) in the DIG2 Computer. Make sure all cables are clear of the GPU Card and the card seats firmly in the Systemboard.

    Figure 8. VDIG2 Computer GPU Card Slot Location

  2. Reinstall the Phillips Screw to secure the GPU Card to the chassis.
  3. Reconnect the Power Supply Connector to the rear of the GPU Card.
  4. Reinstall the Expansion Card Hold-down Clamp in the DIG2 Computer Chassis.

    Figure 9. DIG2 Computer Expansion Card Hold-down Clamp Placement

    note:

    The Expansion Card Hold-down Clamp must be installed as illustrated above. The Clamp should be centered over the Cooling Fan with slotted end over expansion cards.

  5. Reinstall the DIG2 Computer Chassis Cover and lock the cover in place.

5 Re-Install DIG2 Computer

IMPORTANT: IN ORDER TO MEET EMC REQUIREMENTS, THE CHASSIS COVERS MUST BE PROPERLY INSTALLED AFTER SERVICING. CHECK THAT THE COVERS ARE MOUNTED FIRMLY IN PLACE AND LOCKED DOWN WHERE APPLICABLE.

Procedure

  1. Slide the replacement DIG2 Computer into the Operator Console from the front.
  2. Replace the four (4) 5mm socket cap screws and washers to secure the DIG2 Computer chassis to the Operator Console rack. Torque to 4.6 N-m.
  3. Mount the power cord to the rear of the DIG2 Computer chassis and verify that its power supply switch is turned to the ON position.
  4. Replace the rear cable connection(s).

    For cabling details, refer to the appropriate interconnect located in the System Diagrams folder of this service methods publication.

6 Power-On the Operator Console

Procedure

  1. Reconnect the Twist-N-Lock Main Power Cable from rear of console and remove Lockout Tagout protection applied earlier.
  2. Power ON the Operator Console at the console’s front panel switch.
  3. Visually verify the DIG2 Computer front panel Power LED is illuminated. If not, press the DIG2 front panel power switch to apply power to the DIG2 Computer.

7 Verify Replacement DIG2 Computer GPU Card Operation

Procedure

  1. Verify that the DIG2 Computer has powered up.
  2. Verify that the DIG2 Computer is not displaying or sounding any POST Errors.
    note:

    See DIG2 Troubleshooting if any errors appear.

8 Finalization

Procedure

  1. Refer to System Scanning Tests in the Functional Checks chapter of this manual to confirm proper operation.
  2. Reinstall Console Front and Rear Covers.
