Initial Fabric Interconnect Configuration
The initial configuration for a Fabric Interconnect can be done by using the serial console when the Fabric Interconnect boots for the first time. This can happen either during factory install, or after the existing configuration is cleared. The configuration wizard enables you to select the management mode and other parameters such as the administrative subnet, gateway, and DNS IP addresses for each Fabric Interconnect. For the management mode, you can choose whether you want to manage the Fabric Interconnect through Cisco UCS Manager or Cisco Intersight.
You can change the management mode for the Fabric Interconnects between Cisco Intersight and Cisco UCS Manager. However, this is a disruptive process because it will cause all endpoint configurations to be reset, and will result in the loss of the current configuration.
Note |
All the discovered servers, chassis, and Fabric Extenders (FEX) must be decommissioned before changing the management mode. |
The erase configuration option, which is available in both management modes, allows you to clear the existing configuration and reboot the Fabric Interconnects. After the Fabric Interconnects are rebooted, the initial configuration screen appears, and you can configure the Fabric Interconnects with the appropriate management mode.
Note |
Cisco UCS 6500 Series Fabric Interconnects support UCSM Managed Mode (UMM) from firmware version 4.2(3b) onwards. |
To configure the Fabric Interconnects in a cluster:
After completing the initial configuration of the Fabric Interconnects, you must claim them for use with the Cisco Intersight platform. For more information about claiming devices in Cisco Intersight, see Target Claim in Intersight Managed Mode.
After you claim the Fabric Interconnects, they appear in the list of available devices. The device type for Fabric Interconnects managed through Cisco Intersight is Intersight Managed Domain. The Device IP field shows the IP addresses of both the Fabric Interconnects, and the Device ID field shows the serial numbers of both the Fabric Interconnects. The Fabric Interconnects now appear in the Fabric Interconnects table view.
After you claim the Fabric Interconnects, you must configure the ports on the Fabric Interconnect to discover the connected chassis and servers. For each Fabric Interconnect, you can view the properties, and an inventory of its components, including ports, fan modules, and power supply units (PSUs).
