Hardware Installation

4.5. Connecting Remote MPC Units to the AUX Ports

If your application requires control of more outlets than are provided on your MPC unit, you can also connect up to three additional MPC units to the AUX ports on the MPC front panel. This allows you to control up to 80 outlets via a single IP address.

To connect optional, Auxiliary MPC units to your local MPC unit, proceed as follows:

1.Install Snap Adapter: Insert a DX9F-WTI-RJ snap adapter (not included) into the serial console port on the Auxiliary MPC unit. The DX9F-WTI-RJ snap adapter can be ordered from the WTI sales department. For a description of the Snap Adapter interface, please refer to Appendix C.1.

2.Install RJ-45 Cable: Connect a straight RJ-45 cable from the AUX port on your local MPC unit to the DX9F-WTI-RJ snap adapter, which has been installed in the serial Console port on the Auxiliary MPC unit.

3.Configuration and Operation: Please refer to Section 5.8.2 for additional configuration instructions for Auxiliary units, and Section 9 for additional operating instructions.

Notes:

•Once the local MPC unit and Auxiliary units have been installed and configured, you must take care when temporarily disconnecting Auxiliary unit(s) from the local unit. Prior to disconnecting Auxiliary units, note the specific AUX port that each Auxiliary unit is initially connected to, and make certain to reconnect each Auxiliary unit to the same AUX port where it was previously connected.

•If Auxiliary units are connected to a different AUX port from where they were located when previously configured, then the local MPC unit and Auxiliary units must be reconfigured in order to adapt to this change.

•When an Auxiliary unit is connected to the AUX port on your local MPC unit, the AUX ports on the Auxiliary unit will be automatically disabled.

•The AUX ports can also be used for connection to console ports on devices such as servers and other rack mount equipment. For more information, please refer to Appendix C.3 and Section 5.8.2.
