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 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 bottom lip of the canister.
   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. Before you can remove the faulty adapter, power down the node canister, as described in Procedure: Powering off a node.
3. At the rear of the enclosure, the adapter is located in a cage. There may be another adapter in the same cage. Label each network cable connection or record all cables that are connected to each adapter in the cage, using a table such as shown in Table 1

   Table 1. Cable identification for adapters in the cage being serviced

   Slot numbers contained in cage
   Adapter in slot 1 of the cage				Adapter in slot 2 of the cage
   Port 1 cable:				Port 1 cable:
   Port 2 cable:				Port 2 cable:
   Port 3 cable:				Port 3 cable:
   Port 4 cable:				Port 4 cable:

4. Use the management GUI to shut down the node canister containing the adapter that requires replacement.
5. Wait for the node to shut down. Refer to the status LEDs to determine that the node has shut down before proceeding to replace the adapter.

6. If applicable, remove each SFP from each port of the failed adapter , 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, to ensure they can be returned to the same port in the replacement adapter.
7. Locate the eject handle on the left side of the cage containing the failed adapter. Release the cage from the canister by pulling the blue end of the cage release lever downwards.
8. Slide the adapter cage from the canister. Ensure other cables allow for removal of the adapter cage containing the adapter.
9. Press the adapter out of the PCIe socket of the adapter cage.
   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

10. Review Table 2 to ensure that you are using the correct replacement adapter.

    Table 2. Summary of network adapters and SFP devices

    Type	Adapter	SFP device
    Quad-port 64 Gbps Fibre Channel
    Quad-port 32 Gbps Fibre Channel
    Dual-port 25 Gbps Ethernet (iWARP)
    Quad-port 12 Gbps SAS		Not applicable
    Dual-port 100 Gbps Ethernet

11. Align the replacement adapter with the PCIe socket of the adapter cage and press the adapter into place. Ensure that the adapter is fully seated in the riser, as shown in Figure 1.

    

12. Ensure the both adapters or PCIe card filler are well seated.
13. Insert any SFP devices that were removed into the adapter.
14. Align the adapter cage so that the adapter SFPs face out of the canister and the adapter cage lever is fully open.
15. Push the adapter cage into the proper slot until the lever begins to move, the press the handle up and in until it clicks into place.
16. Reconnect the network cables to the rear of the canister, by using the information that you collected at step 3.
17. Verify that the error is cleared from the Event Log.
