Removing and replacing a network adapter: 2145-SV2 and 2145-SA2

Use this procedure to remove and replace a network adapter system with a new one received from stock.

About this task

Notes:
  • When a node canister is removed, do not operate the system for more than 16 minutes. Operating the system for longer than this period might cause the node to shut down due to overheating.
  • No tools are required to complete this task. Do not remove or loosen any screws when you remove or replace an adapter. The adapter is not attached to the PCIe riser by screws.

Procedure

  1. Identify the node with the faulty adapter.
    1. Identify any dependencies on the node canister by using the management GUI. Understand the impact of any dependencies and resolve them if necessary.
    2. Locate the node that requires servicing by its MTM and serial number (S/N), which are labeled on the node front left cover and also on the node rear. At the rear of the enclosure, locate the node canister by finding its serial number on the release handles.
    3. Use the Event Log to identify the location of the adapter that requires replacement. Location information includes the node MTM and S/N, node canister (slot number/serial number), and the adapter slot number.
  2. Label each network cable connection or record all cables that are connected to the node canister. This information is used to reconnect the cables to the node canister.

    Use the following table to summarize the type of adapter that is used in each PCIe slot and the port configurations of the node canister.

Removing the host interface adapter

  1. Remove the node canister, as described in Removing and replacing the node canister in the node: 2145-SV2 and 2145-SA2.
  2. Remove the cover and set it aside, as described in Removing and replacing the cover of the canister: 2145-SV2 and 2145-SA2.
  3. At the back of the node canister, locate the PCIe slot of the adapter that is to be replaced.

    When the node canister is removed, the PCIe adapter slots are numbered 1 - 3, bottom to top, as shown in the following figure.

  4. If applicable, remove each SFP from each adapter port, as described in Removing and replacing a Fibre Channel SFP transceiver: 2145-SV2 and 2145-SA2.

    Record the serial number of each SFP device as you remove them from the adapter ports.

  5. Lift the adapter and PCIe riser from the canister.
  6. Press the adapter out of the PCIe socket of the riser.
    Important: Adapters with a large SFP cage, such as the 4-port Fibre Channel adapter, might have limited clearance between the external edge of the SFP cage and the slot of the PCIe riser. When you remove or insert an adapter, you might need to start the removal at the bracket end of the adapter, so that the adapter is removed at a slight angle.

Replacing the adapter

  1. Review the following table to ensure that you are using the correct replacement adapter. See SAN Volume Controller 2145-SV2 and 2145-SA2 parts for the applicable part numbers.

  2. Align the replacement adapter with the PCIe socket of the riser and press the adapter into place. Ensure that the adapter is fully seated in the riser, as shown in Figure 2.

  3. Ensure the bracket of the PCIe riser is aligned correctly, as shown in Table 3.

  4. Insert any SFP devices that were removed in step 6 into the adapter. See Table 2 to ensure that you are using the correct SFP device.
  5. Align the riser so that the adapter SFPs face out of the canister and the PCIe connector of the riser faces down into the PCIe socket of the canister.
  6. Carefully press the PCIe riser into place.
  7. Replace the canister lid, as described in Removing and replacing the cover of the canister: 2145-SV2 and 2145-SA2.
  8. Reinsert the node canister, as described in Removing and replacing the node canister in the node: 2145-SV2 and 2145-SA2, and reconnect the power cables.

    If the node canister does not start, check that the canister is fully inserted into the enclosure.

  9. Reconnect the network cables to the rear of the canister, by using the information that you collected at step 2.
  10. Verify that the error is cleared from the Event Log.
