I have three ESW-540-48 switches and we are currently moving our office to VoIP telephony. The main reason we bought these switches was VoIP however I'm not really sure what I'm doing wrong but I can configure PoE on those switches.
Everytime I try to open PoE Settings on this switch I get the following information:
System currently contains no POE supporting units
For test purpose I have conecte one of the Cisco VoIP SPA504G phone directly to the switch on eth0/40, phone doesn't turn on and it looks like power signal is not sent to the phone.
Do I need any additional PoE module for this switch or is there anything else I miss there?
