Getting a new VOIP phone system. We also just installed a new Meraki 48 port POE switch. The phone guys said that I can run the phone off of just the network cable if it is plugged into the POE switch. I do have a question about this. I have a few computers that are using a small 5 port Netgear switch. I was wondering how this will work with the VOIP phones. The network cable right now goes from the wall to the Netgear switch and then a cable comes from the switch to the existing phone (this is also a VOIP system. 3com NBX 100) and another cable comes from the switch to the computer. I did this because the 3com phones we have currently are only 10MB. The Netgear switch is 10/100/1000. So can I still use the Netgear switches I have with the new phone system and not have to use a power adapter because the phone can run power over ethernet from the switch or does the Netgear switch mess things up with powering the phone? FYI. The cable running from the wall to the Netgear switch is plugged into a POE port on the Meraki.
If the small 5 port switch is not poe, the phones will not power up without a power adapter. Just because that small swtich is getting a poe signal, it can not pass the power off to those device through the 5 port swtich.
