So it appears that this has been factory provisioned with Zero-Touch
From the Provisioning Guide...
Obihai ZT is a proprietary technology for “late customization” for service provider customers. Customization is finalized when the unit is first plugged in at the end-user’s location. This allows service providers to ship devices in their original packaging to end-users without any pre-configuration.
When a service provider customer places an order with Obihai for ZT devices, it must also define a ZT profile (or re-use an existing one previously defined). A ZT profile is just a device configuration profile with a small number of customized device parameter values. The ZT profile must be validated and approved by Obihai Technology. When ZT units are shipped from the factory, Obihai records vital information (such as MAC and Serial#) for each device and links it in a database to the ZT profile already defined for that shipment. ZT-enabled devices leave the factory in the “pre-customized” state. While in this state, the device will continuously attempt to complete customization by downloading its ZT profile from the ZT Server at Obihai.com. Its functionality is otherwise very limited in this state: end-user may change some basic network parameters such as DHCP and IP address, but may not set up a service provider’s service for example. A very basic ZT profile would include a ConfigURL that points to a provisioning server managed by the service provider.
When a ZT profile is successfully downloaded and stored, the device operates in the “customized” state. It is in this state that the device can operate normally under the management of the service provider. The service provider should bear in mind the following points regarding their ZT devices:
As the ZT profile is defined, each parameter specified in the profile may be permanently locked down. No one can change the value of a locked down parameter after the unit is customized.
Factory resetting the device restores all the customized parameters to the values defined in the original ZT profile; other parameters are restored to their corresponding factory default values
