Removing and replacing an interface adapter

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

1. Identify the canister with the faulty interface adapter.
   1. Identify any dependencies on the canister by using the management GUI. Understand the impact of any dependencies and resolve them if necessary.
   2. Locate the canister that requires servicing by its MTM and serial number (S/N), which are labeled on the enclosure front left latch.
   3. Use the Event Log to identify the location of the adapter that requires replacement. Location information includes the enclosure MTM and S/N, 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 canister. This information is used to reconnect the cables to the canister.
   Table 1 summarizes the type of adapter that is used in each PCIe slot and the port configurations of canister 1 (the left canister).

   Table 1. Canister 1 PCIe slots and port connections

   PCIe slot 1 Adapter type				PCIe slot 2 Adapter type
   Port 1	Port 2	Port 3	Port 4	Port 1	Port 2	Port 3	Port 4

   Table 2 summarize the adapters that can be used in each PCIe slot and the port number configuration of canister 2 (the right canister)

   Table 2. Canister 2 PCIe slots and port connections

   PCIe slot 1 Adapter type				PCIe slot 2 Adapter type
   Port 1	Port 2	Port 3	Port 4	Port 1	Port 2	Port 3	Port 4

Removing the interface adapter

3. Remove the canister, as described in Removing and replacing a canister.
4. At the back of the canister, locate the PCIe slot of the adapter that is to be replaced.

   The PCIe adapter slots are numbered 1 - 2, left to right.

5. If applicable, remove the SFPs from the adapter ports, 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.

6. To remove the riser - interface adapter assembly, grasp the assembly by the inner end of the metal riser card cover and the round hole in the cover, and lift the assembly out of the canister, as shown in the following figure.

   

Replacing the interface adapter

7. Review Table 3 to ensure that you are using the correct replacement adapter. See Control enclosure replaceable units for the applicable part numbers.

   Table 3. Summary of interface 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: If used for host connections, you must install the SAS adapter in PCIe slot 1. If used for connections to expansion enclosures, you must install the SAS adapter in PCIe slot 2. Although it is a 4-port adapter, only ports 1 and 3 are supported for SAS connections to expansion enclosures.

8. Align the interface adapter assembly with the side and back of the canister and fit it into place until the riser card connector is fully seated.
9. Insert any SFP devices that were removed in step 5 into the adapter. See Table 3 to ensure that you are using the correct SFP device.
10. Replace the canister, as described in Removing and replacing a canister.
11. Verify that the error is cleared from the Event Log.
