Thought 1: Everything I've seen regarding the initial CCA-driven configuration of a UC520 says to:
- connect a PC (with a DHCP directly up to any switch port on the UC520
- fire up CCA
- tell CCA to 'add a new customer site', specifying IP address 192.168.10.1
Thought 2: Everything I've seen regarding resetting a UC520 to its factory configuration says says to do:
- copy flash:UC520-8U-4FXO-K9-factory-7.0.3.cfg to startup-config
Problem: Performing the factory reset as described doesn't put the UC520 in a state whereby the router has 192.168.10.0/28 configured on its native vlan. Instead, immediately after the router is reloaded, the console displays the "----System Configuration Dialog----". Answering 'N', doesn't assign an IP address to the vlan (or enable ip http secure-server or setup a dhcp pool for that matter). Answering 'y' requires me to enter in some minimal configuration, which kind of defeats the purpose of using CCA for an initial configuration?
How do I configure the UC520 so that it is in the initial condition that CCA expects it to be in?
Best way is to let CCA do this for you.
Download CCA 2.2.1 (the latest) from www.cisco.com/go/configassist
Install it on your PC. Make sure you do not have dual NIC enabled on your PC and no FTP or TFTP servers are running on it.
COnnect the ethernet from your PC to the UC500 LAN port.
Navigate to the MAINTENANCE Drawer on CCA and go to RESTART/RESET.
Select the UC500 and FACTORY RESET
This will take care of IOS/CME and CUE (which must also be reset)
BTW, if you have new code to install (the 8-0-0 bundloe zip is the latest), you can accomplish BOTH a factory reset and an upgrade at the same time using the same Maintenance drawer, but the SW Upgrade tool. Just check both both boxes (format flash and apply factory default).
