PoE+ switches limited to 17w by default?

I've seen this on a few vendors so far but I'm not seeing any documentation to support it.

Most recently, an Aruba 2530 (a J9772A) would drop the PoE load on a new timeclock... we initially diagnosed it as a failed timeclock and wasted weeks troubleshooting the wrong thing. This was additionally complicated because the customer uses Aruba Central, which does not report an error nor allow a method of configuring the switch to go to full power on a port.

Gotta add the following to the interface config:
poe-allocate-by value
poe-value 30

Is this a standard practice I am unaware of? Is this in hopes of preventing lawsuits for large bundles of cables lighting on fire or something?
