# Replace all Expected Racks

`PUT /v2/org/{org}/nico/expected-rack`

Replace the full set of Expected Racks for a Site with the provided list. All existing Expected Racks for the Site that are not in the request body will be deleted, and any new Expected Racks in the request will be created. Existing Expected Racks with matching `rackId` values will be updated.

Every entry in `expectedRacks` must reference the same `siteId` as the top-level `siteId`. `rackId` values must be unique within the request. The `expectedRacks` array may be empty to clear all Expected Racks for the 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 replace Expected Racks if they have an account with the Site's Infrastructure Provider.
