If not already installed, install the rear panel, screwing it to the appropriate mounting locations on the

When power is applied, the unit will perform a self-test to ensure that it is compatible with the network
management software on the system.

After the self-test is performed, check the software provisioning of the unit using either the front panel
craft interface on the front of the controller unit or the network management interface on the rear of the
controller (see the section on network management for more information on this interface).
Note:
If a Secondary T1 unit is inserted into a shelf while power to the shelf is on, the T1 controller
unit may reset.
