We just installed a uc520, an ESW-520 48P and 26 SPA502G phones. The phones are all PoE and we have a limited number of drops around our location, so there are multiples places where the PoE port is the only data port in the vacinity. However there are times when multiple network devices need to be attached at that location (printers, computers) and I am attempting to run the data port out of the SPA502G to a simple switch which is then connected to multiple network devices. (Because the phone is PoE, it has to be the first device inline from the data port.)
However, I have found that only one of the network devices (which one is generally a crapshoot) is able to have connectivity with the network.
The only change that has been made to the data section of the system is that a Cisco rep turned off DHCP for the data port so that our W2k3 DHCP server could still be the one to lease out the IP addresses for the data side.
Anyone know how I can get multiple devices connected through the phone without resulting to purchasing PoE switches for each location that needs one, or buying the 5V adapter?
