Originally we used just POE but now each of the 3 panels has its own PSU

We have a strange a strange issue at a client they have 3 panels on their
phone and every so often the panels reboot themselves yet the phone stays
We decided to replace the T26 for a T28 to see if it fixes the issue and
still have the exact same issue.
Has anyone seen this before?
I frequently use the newer T48G and T46G phones with the EXP40 expansion
module. There are issues, if you are logged into the phone via the
webinterface as an admin. Among other things, the display is not properly
updated and wrong numbers may get dialed. Some time ago, there was a
firmware update and I am not aware of any stability issues at the moment.
How do you supply power? 3 expansion modules + the phone and a cheap POE
switch could be critical. It may not be the power itself, but the correct
handling of energy saving states.
