Reassigning IP address PC5324

​ I am a beginner on configuring these PC5324's, I have only done what I need to do with them. We run a seperate VLAN for voice to divide our traffic so I configure that in but thats about the extent of my knowledge besides assigning an IP and username and password. I was told by my boss to reassign a different IP to a particular switch. It will not let me do this and gives me the error of " ​​“duplicated ip interface on the same subnet” I can ping the IP address that I am trying to assign with no reply so the IP Address should be available. I know I can reconfigure this switch if I get it to factory defaults or maybe someone has some ideas on how I can fix this problem? Either one would be great, thanks​​ ​

You can not have 2 ip addresses on the switch that are on the same subnet.  For example:
 
10.10.10.1 255.255.255.0
10.10.10.2 255.255.255.0
 
are on the same subnet because the corresponding numbers in the address to the 1's in the mask are the same.  i.e. the network portion of the IP address is the same.
 
The following:
 
10.10.10.1 255.255.255.0
10.10.11.2 255.255.255.0
 
can both be on the switch because the network portion is different.
 
If you can't figure it out, post you config and tell us the IP address you are trying to put on it.

Here is a running-config of what I have right now and IP address I want it to have is 172.18.1.27/255.255.0.0.  Any help is appreciated.  Thanks  I have deleted all the "exit"'s to save some space.

First, you have to delete the IP address you already have, since it is on the same network as the one you are adding (172.18.0.0).  Then add your new IP address.
 

console (config)# interface vlan 1

config (config-if)# no ip address

console (config-if)# ip address 172.18.1.27 255.255.0.0
