The RPS is a 675. Customer reported power issues on 2 x attached 3560'S. 1 did not recover so eng tried to repatch to the second switch which housed 12 x Mitel 5010 IP Phones.. The 2nd switch did not supply POE to any new attached devices even though looking at power allocation for switch all should be fine I.E 374 watt total allocation 12 x IP phones which draw 15.4 w totalling only 184 w.

Any thoughts?

The 675 is only supporting one switch at time. The second 675 is dead in the water. Customer repatches one of the phones away from it onto the switch being powered by the RPS and phone added does not receive power. In essence only 12 phones are being powered should only 184 W being drawn.

Were the switch port connected to any non PoE devices before repatching?

There is a bug in the 3560 IOS.

The Bug ID is CSCsc10999

Problem: Switch does not power PD when non-PD device previously plugged into port

The resolution is to upgrade the switch to atleast Upgrade to 12.2.25SED or higher

Maybe you are running into this issue
