SPARC T5-8 Server Service Manual

Remove a Card Carrier

The server supports single-wide and double-wide card carriers. The removal steps are the same for both carrier widths. This topic includes illustrations only for the single-wide carrier.

PCIe expansion cards with their carriers are hot-service components that can be replaced at any time if the card is not in use.

---

Caution  -  To remove a PCIe card that is assigned to an I/O domain, first remove the device from the I/O domain. Then, add the device to the root domain before you physically remove the device from the system. These steps enable you to avoid a configuration that is unsupported by the Direct I/O or SR-IOV feature. For more information about making hardware changes to an I/O domain, refer to the Oracle VM for SPARC documentation.

For the location of the PCIe card carriers, see Rear Panel Components (Service).

---

Caution  -  This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause server components to fail.

---

1. Take the necessary ESD precautions.

   See Prevent ESD Damage.

2. Start this procedure with the primary domain at the Oracle Solaris prompt.

   ---

   Note - Removing a PCIe card carrier while the primary domain is at the Open Boot prompt is not supported.

   ---

3. Locate the PCIe card carrier at the rear of the server.
   • See Rear Panel Components (Service) for the locations of the carriers in the server.
   • See Determine Which PCIe Card Is Faulty to locate a faulty PCIe card.
4. Determine if you are removing a card carrier from a running server.

   • If you are removing a PCIe card from a server that is running (that is, if you are hot-swapping the card), go to Step 5.

   • If you are removing a card from a powered-down server, go to Step 7.

5. Take the card offline.

   You can use the Attention button or the CLI to hot-swap the card from the server.

   • Attention button:
     1. Press the button to bring the card offline.

        The Power OK LED should go off, indicating that the card is ready to be removed.

     2. Go to Step 7.
   • CLI:
     1. At the Oracle Solaris prompt, list all of the PCIe devices in the device tree:

        # hotplug list -l | grep PCIE

        This command lists dynamically reconfigurable PCIe resources and shows their operational status. In this case, look for the status of the card you plan to remove.

        Example:

        /pci@300/pci@1/pci@0/pci@6 [PCIE1] EMPTY
        /pci@340/pci@1/pci@0/pci@6 [PCIE3] ENABLED
        /pci@380/pci@1/pci@0/pci@a [PCIE9] EMPTY
        /pci@3c0/pci@1/pci@0/pci@e [PCIE11] EMPTY
        /pci@400/pci@1/pci@0/pci@c [PCIE2] EMPTY
        /pci@440/pci@1/pci@0/pci@c [PCIE4] EMPTY
        /pci@480/pci@1/pci@0/pci@4 [PCIE10] EMPTY
        /pci@4c0/pci@1/pci@0/pci@8 [PCIE12] EMPTY
        /pci@500/pci@1/pci@0/pci@e [PCIE5] EMPTY
        /pci@540/pci@1/pci@0/pci@e [PCIE7] ENABLED
        /pci@580/pci@1/pci@0/pci@a [PCIE13] EMPTY
        /pci@5c0/pci@1/pci@0/pci@8 [PCIE15] EMPTY
        /pci@600/pci@1/pci@0/pci@8 [PCIE6] EMPTY
        /pci@640/pci@1/pci@0/pci@8 [PCIE8] EMPTY
        /pci@680/pci@1/pci@0/pci@4 [PCIE14] EMPTY
        /pci@6c0/pci@1/pci@0/pci@4 [PCIE16] EMPTY

     2. Disable the PCIe card.

        Example:

        # hotplug disable /pci@340/pci@1/pci@0/pci@6 PCIE3

6. Power off the PCIe card.

   Example:

   # hotplug poweroff /pci@340/pci@1/pci@0/pci@6 PCIE3

7. Disconnect any transceivers, if applicable, and all of the cables connected to the PCIe card.

   ---

   Tip  - Label the cables to ensure proper connection to the replacement card.

   ---

8. Pull the carrier's handle down to disengage the carrier from the card cage.
   
9. Remove the carrier from the server.
