Limit Your Use of Manual Registration

Caution	In addition to our support for Medianet features to autoregister your DMPs, DMM includes an efficient, timesaving
		feature of its own to autoregister your DMPs. Despite the presence of two robust and largely automated methods, you
		can register a DMP manually for testing purposes.
		We recommend that you never use the method to register a DMP manually, except in a lab for testing purposes. Manual registration
		is neither suitable for, nor scalable in, a production network.
		Eventually, when autoregistration finds and adds a DMP that you registered manually, the device inventory database develops
		multiple records for the one device. We see this duplication as an IP address conflict, which interferes with normal operation and
		triggers an alarm in DMS-Admin.

General Best Practices for Non-Medianet Autoregistration

Choose Network Ranges Cautiously

When you autoregister DMPs that are new to your DMM appliance, they restart immediately even when they are known already to another DMM appliance, and even when they are running an event. Therefore, when your organization uses more than one DMM appliance, be careful to autoregister only those DMPs that you are not already managing centrally elsewhere. Otherwise, you might temporarily disrupt media playback for the signs in your network.

Best Practices to Schedule Non-Medianet Autoregistration Events

Stagger Deployment Schedules

DMP autoregistration operations that are native to DMM (as opposed to the superficially similar operations in a Medianet) occur in a sequence that does not tolerate disruption.

•You can schedule multiple DMP autoregistration operations to run simultaneously only when they will all search the same one subnet.

•However, when you define DMP autoregistration operations to search more than one subnet, you must not schedule them to run simultaneously, or even to overlap. When they overlap, only the first of them can run at all. Furthermore, DMM does not show any error message to explain why the similar operations all failed.
