The following table describes the maximal card dimension supported in each slot.
Table 1. The maximal card dimension supported in each slot.

Riser-card assembly Slot number The maximal card dimension supported
Riser-card assembly 1 1 Full height, up to full length
2 Full height, up to full length
3 Full height, half length
  4 Low-profile
5 Low-profile
Riser-card assembly 2 6 Full height, up to full length
7 Full height, up to full length
8 Full height, half length

The following notes describe the types of adapters that the server supports and other information that you must consider when you install an adapter:

Attention:
  1. Do not install over 3 ServeRAID M1215 SAS/SATA controllers in one system.
  2. Do not install the NVIDIA Grid Kx/Mxx, the NVIDIA Quadro Kxxxx or the NVIDIA Tesla Kxx adapter options in systems containing 1 TB of system memory or more. If these options are installed in systems with 1 TB of memory or more, it might cause undetected data corruption and system instability. These options are only supported in systems containing less than 1 TB of memory. For more information, go to https://support.lenovo.com/us/en/documents/migr-5096047.

To replace an adapter, complete the following steps:

  1. Read the safety information that begins on Safety and Installation guidelines.
  2. Turn off the server and peripheral devices and disconnect the power cords and all external cables.
  3. Remove the server top cover (see Removing the top cover).
  4. Determine which expansion slot you will use for the adapter. If you are installing an adapter in PCI expansion slot 1, 2, or 3, remove riser-card assembly 1; if you are installing an adapter in expansion slot 6, 7, or 8, remove riser-card assembly 2. See Removing a riser-card assembly
  5. 1 Slide the retention bracket; then, 2 rotate it to the open position.
  6. Slide the expansion-slot cover out of the riser-card assembly expansion slot.
  7. Align the adapter with the PCI connector on the riser card and press the adapter firmly into the PCI connector on the riser card.

  8. Rotate the retention latch to the close position.
    Note: Fasten the screw on the retention latch to secure the adapter.
  9. If you are installing a full-height, full-length adapter, insert the shipping brackets.

  10. Connect any required cables to the adapter.
    Attention:
    • When you route cables, do not block any connectors or the ventilated space around any of the fans.
    • Make sure that cables are not routed on top of components that are under the riser-card assembly.
    • Make sure that cables are not pinched by the server components.
  11. Align the riser-card assembly with the selected PCI connector on the system board and align it with the slots on the chassis; then, lower it into the server and press down firmly until the riser-card assembly is seated correctly in the connector on the system board.
    • For half-length and low profile adapters

    • For full-height, full-length adapters
      Note: Shipping brackets are only included in the server that is pre-configured with full-height, full-length adapters

  12. Perform any configuration tasks that are required for the adapter.
  13. Reinstall the top cover (see Replacing the top cover).
  14. Slide the server into the rack.
  15. Reconnect the power cords and any cables that you removed.
  16. Turn on the peripheral devices and the server.
