But the danger is, you are going to loose link.
I suspect these devices will be like most other modern systems and typically not consume anything like their peak current most of the time, for networking hardware I'd imagine this will only be when the link is saturated and could depend on factors like how long the physical links are. If it's anything like other similar hardware you may also be making power requests with a very low resolution specification of the consumption so have conservative allocation end up rejecting systems that should work.
