Replacing the optional PCI or ML2 adapter

Use this information to replace the optional PCI or ML2 adapter.

Read the safety information in Safety and Installation guidelines.

If you are replacing a server component in the water-cooled technology tray, you need to remove the water-cooled technology tray from the chassis enclosure and refer to the Removing a water-cooled technology tray from a chassis and Installing a water-cooled technology tray in a chassis sections.

To replace the optional PCI or ML2 adapter, complete the following steps.

註
  • If your adapter was previously configured, backup or record its configuration information, if possible, before replacing the adapter. See the documentation for your adapter for information and instructions.
  • In the legacy mode, this system has limited ROM space for installed options. At most four network interface cards (NICs) are supported for legacy PXE boot. If more than four NICs are installed, legacy PXE boot will not be attempted on some of the NICs. To enable legacy PXE boot on the desired NIC connectors, prioritize the desired NIC connectors by changing the ROM execution Order or disable the NIC connectors that you do not use from the Enable/Disable Adapter Option ROM Support menu.
  1. Turn off the water-cooled technology tray and peripheral devices and disconnect the power cords and all external cables.
  2. Remove the cover (see Removing the cover).
  3. Disconnect the cables from the adapter.
  4. Insert the adapter/ML2 card into the PCI riser-cage assembly/ML2 riser card assembly, aligning the edge connector on the adapter/ML2 card with the connector on the PCI riser-cage assembly/ML2 riser card assembly. Press the edge of the connector firmly into the PCI riser-cage assembly/ML2 riser card assembly. Make sure that the adapter/ML2 card snaps into the PCI riser-cage assembly/ML2 riser card assembly securely.

  6. Connect the cable to the newly-installed adapter/ML2 card if there is one.
  7. Reinstall the cover (see Replacing the cover).
  8. Slide the compute node into the rack.
  9. Reconnect the power cords and any cables that you removed.
  10. Turn on the peripheral devices and the compute node.
