Sorry if I'm resurrecting an old thread, I'm new here.
I can't speak for those specific switches, but with most PoE switches you can disable PoE except for the ports you'll use, and up the max power draw on those ports (sometimes called a poe profile)
Edit: After logging into a customers switches, I found the option:
Port, POE, Setup, and from there selectively enable or disable the power per port.
From that point, under "PoE Mode for selected & enabled ports", select "Guarantee", which does the following: "This will allocate 25 Watts to the selected port(s)
from the overall power budget available. This setting will override the "Auto" port PoE
priority based on port numbers."
Also this is on that page, to the right:
"Guarantee Power Summary
Total PoE Available = 180W
Guaranteed PoE = 0W
Remaining (Available - Guaranteed) = 180W "
So you're guaranteed full wattage up to 25 watts for 7 ports, (7 * 25.5 = 178).
There's a 2.00.01 firmware update from HP, but it merely says "first hp release" in the release notes, with no changes mentioned, so it may merely rebrand the admin interface as HP.
