I've been looking more at these; APC offers an 8-sensor controller/hub ($800) and a 2-sensor controller/hub. But in both cases, the total cable length for the sensor bus is 132 feet. That's pretty short. I'll need to use several controller/hubs to reach around my datacenter. They can be wall-mounted, but then I need to run power to each wall-mounted unit. That's why I'm interested in PoE.
I may have several powered Horizontal Distribution Areas where I can place three controllers, then control the sensors from there. But I'm wondering what a TIA-942 audit will think of that solution (putting environmental monitoring systems in Distribution Areas).
