All the modern enterprise ones will support network management, but the thing to keep in mind is a UPS is essentially an insurance policy - you've got to keep up with the premiums (maintenance, replacing the batteries as they age out, testing, ...) if you want to be able to trust that they'll work on the one day a year that you need them.

Related anecdote - I know of a company that spent several million dollars installing a backup diesel generator in their secondary DC. Several years later, a new CIO came in and decided that they should actually be practicing the DR plans that they had in place, and one of those plans involved shifting all their load off DC A onto DC B, then switching DC A onto backup power for half an hour or so. Test day came and they managed to switch the load over with minimal issues, then they switched the power over to backup and... nothing. UPS batteries were several years out of life and lasted less than a minute, and the generator failed to start because it had never been maintained - turns out fuel goes bad if you leave it sitting in a tank in the sun for years, and trying to start a large engine with no lubricant really messes stuff up. Cost them mid-6-figures to get the generator torn down and rebuilt - manufacturer laughed them out of the room when they tried to claim warranty. Don't know if they tried to start the generator at the primary DC, but I suspect some bricks were shat thinking about how far in breach of contract they could be with some of their clients
