VeRB2 GPU Replacement

Prerequisites

Overview

This procedure describes and illustrates the steps necessary to replace the Volume Reconstruction Box Computer (VeRB2) 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 VeRB2 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 VeRB2 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 VeRB2 Computer chassis.
  4. Remove the four (4) 5mm socket cap mounting screws and washers from the front of the VeRB2 Computer chassis, holding the chassis to the Operator Console rack.

    Figure 3. VeRB2 Computer Mounting

  5. Slide the VeRB2 Computer chassis forward (out the front of console) and set aside.

3 Remove GPU Card from VeRB2 Computer

Procedure

  1. At the rear of the VeRB2 Computer Chassis, release the Chassis Cover Lock using a Phillips screwdriver. Back out lock screw at least two (2) full turns.

  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.

4 Install Replacement GPU Card in VeRB2 Computer

Procedure

  1. Carefully install the replacement GPU Card in the same location (slot) in the VeRB2 Computer. Make sure all cables are clear of the GPU Card and the card seats firmly in the Systemboard.

    Figure 8. VeRB2 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 VeRB2 Computer Chassis.

    Figure 9. VeRB2 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 VeRB2 Computer Chassis Cover and lock the cover in place.
    note:

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

5 Re-Install the VeRB2 Computer

Procedure

  1. Slide the replacement VeRB2 Computer into the Operator Console from the front.
  2. Replace the four (4) 5mm socket cap mounting screws and washers to secure the VeRB2 Computer chassis to the Operator Console rack. Torque to 4.6 N-m.
  3. Mount the power cord to the rear of the VeRB2 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 VeRB2 Computer front panel Power LED is illuminated. If not, press the VeRB2’s front panel power switch to apply power to the VeRB2 Computer.

7 Verify Replacement VeRB2 Computer GPU Card Operation

Procedure

  1. Verify that the VeRB2 Computer has powered up and is not displaying or sounding any POST Errors.
    note:

    See the VeRB2 Troubleshooting procedure if any errors appear.

  2. No other verifications steps required.

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.
