CAUTION
Sharp edges, corners, or joints nearby.
Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

Procedure

  1. Install the riser assembly into chassis.
    Figure 1. Front high watts GPU riser assembly installation

    1. Carefully slide the riser assembly into the chassis until the riser assembly is seated in place.
    2. Fasten two screws to secure the riser assembly.
    3. Fasten the two thumbscrews at the rear of riser assembly.
  2. For PCIe riser assembly 7, connect cables to the system board assembly. Make sure to complete the following procedure to route the cables.
    Note
    SR650a V4 supports up to two high watts GPUs (up to 600W) installed in Slot 21 and Slot 23 of PCIe riser assembly 7. In configuration with high watts GPUs, PCIe riser assembly 6 comes without riser cards.
    1. Connect the signal cable of Slot 23 riser card (the lower riser card in the riser cage) to PCIe connector 1 and PCIe connector 2 on the system board. Then, route the cable between the bracket and the chassis wall as shown in the illustration. Press the cable down to the bottom of chassis.
      Note
      If necessary, bend the cable to make sure it is fully secured in the space between the bracket and the chassis wall.

    3. Bend the GPU power cable from the upper GPU adapter downwards. Then, route the two GPU power cables along the wall at chassis bottom as shown in the illustration.
      Note
      When routing the GPU power cables along the wall, do not let the cables cover each other.
