Removing and replacing a network adapter

Use this procedure to remove and replace a network adapter, such as a host interface adapter or SAS adapter, in a FlashSystem 7300 system with a new one received from stock.

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 control enclosure that requires servicing by its MTM and serial number (S/N), which are labeled on the enclosure front left cover and also on the enclosure 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 enclosure 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. The orientation, slot numbers, and port numbers of node canister 1 (top canister) differ from node canister 2 (bottom canister)

3. Remove the node canister, as described in Reseating a node canister in the control enclosure.
4. Remove the cover and set it aside, as described in Removing and replacing the cover of a node canister.
5. 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 Figure 1.

6. If applicable, remove each SFP from each adapter port, as described in Removing and replacing an SFP transceiver.

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

7. Lift the adapter and PCIe riser from the canister.
8. 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 host interface adapter

9. Review Table 1 to ensure that you are using the correct replacement adapter.

   Table 1. Summary of network adapters and SFP devices

   Type	Adapter	SFP device
   4-port 16 Gbps Fibre Channel
   4-port 32 Gbps Fibre Channel
   2-port 25 Gbps Ethernet (iWARP)
   2-port 25 Gbps Ethernet (RoCE)
   4-port 12 Gbps SAS		Not applicable
   Notes: Although it is a 4-port adapter, only ports 1 and 3 are supported for SAS connections to expansion enclosures.

10. 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.

    

11. Ensure the bracket of the PCIe riser is aligned correctly, as shown in Table 2.

    Table 2. Aligning the brackethost interface adapter

    Correct Alignment	Incorrect alignment

12. Insert any SFP devices that were removed in step 6 into the adapter. See Table 1 to ensure that you are using the correct SFP device.
13. 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.
14. Carefully press the PCIe riser into place.
15. Replace the canister lid, as described in Removing and replacing the cover of a node canister.
16. Reinsert the node canister, as described in Reseating a node canister in the control enclosure, and reconnect the power cables.

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

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