# Create Expected Switch

`POST /v2/org/{org}/nico/expected-switch`

Create an Expected Switch to pre-register network switches expected to be discovered at a Site.

Org must have an Infrastructure Provider entity. User must have authorization role with `PROVIDER_ADMIN` suffix.

Alternatively, Tenant Admins with `TargetedInstanceCreation` capability can also create Expected Switches if they have an account with the Site's Infrastructure Provider.

- ExpectedSwitchCreateRequest — Request data to create a new Expected Switch. Note: BMC and NvOS credentials (username/password) are only accepted during creation and updates but are not returned in responses.
  - `siteId` string, uuid, required — ID of the site the Expected Switch belongs to
  - `bmcMacAddress` string, required — MAC address of the Expected Switch's BMC (Baseboard Management Controller)
  - `defaultBmcUsername` string, nullable — Username for accessing the Expected Switch's BMC
  - `defaultBmcPassword` string, nullable — Password for accessing the Expected Switch's BMC
  - `switchSerialNumber` string, required — Serial number of the Expected Switch
  - `nvOsUsername` string, nullable — NvOS username for the Expected Switch
  - `nvOsPassword` string, nullable — NvOS password for the Expected Switch
  - `nvosMacAddresses` string[] — MAC addresses of the Expected Switch's NvOS management interfaces
  - `rackId` string, nullable — Optional rack identifier for this component
  - `bmcIpAddress` string, nullable — Optional BMC IP address (IPv4 or IPv6). When set, pre-allocates a reserved IP for the BMC.
  - `name` string, nullable — Display name for this component
  - `manufacturer` string, nullable — Manufacturer of this component
  - `model` string, nullable — Model of this component
