how to configure a uc540 from scratch

I am a complete noob to cisco cli, I have purchased a uc540 from ebay that appears to be defaulted.

Cisco UC540W-BRI-K9 (MPC8358) processor (revision 0x100) with 249856K/12288K bytes of memory.Installed image archive

Processor board ID FHK1420775Q
MPC8358 CPU Rev: Part Number 0x804A, Revision ID 0x20
14 User Licenses
10 FastEthernet interfaces
2 ISDN Basic Rate interfaces
2 terminal lines
1 Virtual Private Network (VPN) Module
4 Voice FXS interfaces
1 Voice MoH interface
1 802.11 Radio
1 cisco service engine(s)
128K bytes of non-volatile configuration memory.
254464K bytes of ATA CompactFlash (Read/Write)

         --- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]:

and after a week of reading blogs i cannot get this unit back to factory default so i can connect to with the cli

There is no dhcp on the interfaces and it will happily pass data from my lan when plugged into expansion port


What i am trying to do is connect the WAN port to a public ip of

and a lan side of for the UC540

and have the box run firewall, voip dhcp etc.

I have a box full of Cisco 7941G phones with SCCP firmware on aswell

every time i have tried to configure the box based on bloggs i get errors in relation to integrated-service-engine0/0.



Since you are new to CLI I

Since you are new to CLI I would suggest using CCA to configure the UC500. It is pretty straightforward and you could go back after and review what it did in the CLI. If you would prefer to do CLI you could post your running config and the errors related to ISE0/0 would be helpful.

I cant get to the cca that

I cant get to the cca that where i aiming for :) how do i get the running config

can you get console access on

can you get console access on UC500? What does it look like? If still asking for initial configuration dialog I would say no. Then you may have to type enable and show run will get you the running config. Sounds like if you are not getting DHCP from the UC500 then the base config is no available. Once you get an IP on an interface you should be able to use CCA.
