N/A You may encounter warnings similar to the following on the Network page of the Data Manager Appliance Configuration UI if you do not have the cable connections to the DM5500 NIC ports properly configured:

Warning: Recommended uplinks in PCIe slot 4:1, PCIe slot 1:2 for appliance are not connected. For optimal performance and redundancy, all 4 uplinks must be connected. Make sure all 4 uplinks are connected and then refresh the page to resolve the warning. For more information on cable connectivity to appliance, refer to the Install guide. You can ignore the warning and proceed with the configuration, however you may experience degraded performance.

Critical: Mandatory uplinks in PCIe slot 4:1, PCIe slot 1:2 for appliance are not connected. Make sure required uplinks are connected to network switch with appropriate cables and then refresh the page to resolve the critical error. It is recommended to connect all 4 uplinks to appliance for optimal performance and redundancy. For more information on cable connectivity to appliance, refer to the Install guide. You cannot proceed with the configuration until the required uplinks are connected.

  • Make sure the four cable connections to the NIC ports on the DM5500 are configured as follows:
    • Two links go to port 1 and port 2 on PCIe slot 1.
    • Two links go to port 1 and port 2 on PCIe slot 4.
