# Update Expected Rack

PATCH https://nico-rest-api.nico.svc.cluster.local/v2/org/{org}/nico/expected-rack/{id}
Content-Type: application/json

Update an existing Expected Rack identified by its `id`.

Org must have an Infrastructure Provider entity. User must have `FORGE_PROVIDER_ADMIN` role.

Infrastructure Provider must own the Expected Rack.

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

        An Expected Rack represents a rack that is expected to be discovered at
        a Site. The `rackId` is an operator-supplied string identifier (not a
        UUID) that uniquely identifies the rack within the Site. Each Expected
        Rack references a Rack Profile that describes the rack's expected layout
        and capabilities.
