Hi Folks,
We’re experiencing a significant number of problems where our PoE switches
report that Aruba AP-105s are drawing more than 15.4W. When this happens
our switches shut off the power to the offending AP. The problem is
intermittent, but seems to occur repeatedly on the same APs, while never
occurring on other APs. Our diagnostics have eliminated excessive loss in
the cabling as the culprit, which seems to leave two possibilities. Either
there are some Aruba AP-105s which are using more power than they are
supposed to, or our switches are incorrectly measuring the power consumption
of the APs. If the APs are at fault, it’s unlikely that we would be the
only ones with this problem. Is anybody else having any issues with Aruba
AP-105s drawing more than 15.4W?
Yes, We have a few ap105s sitting in a box with this exact issue.
It doesn't appear the be the switch in that we have seen it occur on both
cisco 3560-X and juniper ex3300 switches.
