LAB 7A: Security on UC500 and SR520
Your Internet/WAN connection might be an ADSL or an Ethernet connection, depending on the Cisco
SR520 chassis type.
1 Enter the SR520 LAN IP address in the Connect to field in Cisco Configuration Assistant.
If your connection is rejected, it might be necessary to manually release and renew your DHCP lease to
obtain an IP address from the Cisco SR520, by doing the following:
1. To open a Run window, select Start > Run
2. Enter CMD in the Open field to launch a Windows Command window.
3. Enter ipconfig /release at the Windows command prompt.
4. Enter ipconfig /renew at the Windows command prompt. You should get an IP address that is in the
192.168.75.xxx network.

C:\temp>ipconfig /renew
