ESW 520 24-Port switch with POE not working???

We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system.  We installed them all after configuring with static IP.  Deployed... and all but two work fine.  Can someone assist with tips for troubleshooting why two of them do not work?  There are a couple other switches in the building.   Could it be that a switch "upstream" from the two non-functioning switches is causing an issue?  If so, how do I find out?  When we put back the two "dumb" switches all was fine.  Any tips to help would be much appreciated.

Hi Rachel,

Thank you for posting. You may need to change the Smartport role of the ESW switch port to match what you are connecting to. If you are connecting to another switch, the role should be switch. This is usually what causes the ports to block traffic.
