Module Replacement

As it is not a perfect world there may occasionally be failures in the amplifier modules of systems which will require a complete
swap-out of the module. This is perfectly straightforward back in a workshop but if it has to be done at an event or in an installed
system it will be necessary to restore the settings that had been uploaded to the module being replaced. This chapter deals with
each step in detail to make sure that this is accomplished successfully.

Replace the module

The module needs to be disconnected and removed from the cabinet. This is a straightforward process even with a cabinet
deployed in a flown array as long as you can access the rear of the cabinet safely. See the specific section in the MLA and MLA
Compact chapters for more details.

Reconnect the module

Reconnect all connections, ensure that the module powers up, the fan will briefly run at full speed and the red power LED will
light. Connect U-Net cables to the two ports and ensure that both U-Net LEDs light green. Connect audio input and if required
output connections.

Discover the array

The cabinet can be discovered by using the Device Discovery button in Vu-Net however it will be found as an individual cabinet,
essentially a single box array but in most cases it will be part of an array so the entire array will need to be re-discovered.
First select the array in which the module has been replaced by click and dragging around it so all cabinets are selected;-
Note that all cabinets are shown red as for the purposes of this guide the project is off line.
