I have a UC540 connected to a ESW520 24 Port POE with SPA504G phones.
I have connected a small 5 port switch to the PC connector on the back of the phone. I then have a PC and a Network printer connected to the 5 port switch. Under this configuration I am having trouble with the PC being able to renew its IP Address. I am using DHCP on my Windows server for IP address distribution.
How can I fix this problem and do I need to change a setting for the port on the Cisco 24 Port Switch?
