Re: Can you copy a Catalyst 3500XL existing IOS software?
Recovering from Corrupted Software
Switch software can be corrupted during an upgrade, by downloading the wrong file to the switch, and by deleting the image file. In all these cases, the switch does not pass the power-on self-test (POST), and there is no connectivity.
The following procedure uses the XMODEM Protocol to recover from a corrupt or wrong image file. There are many software packages that support the XMODEM protocol, and this procedure is largely dependent on the emulation software you are using.
The following procedure is how I under took to recover a switch. From my limited knowledge there are slightly different ways in recovering a switch dependent upon the given circumstances.
There is a host of Cisco documentation available however may I make reference to ?Recovery From Corrupt or Missing Software Image on Cisco Catalyst 2900XL and 3500XL?.
When the Catalyst 3500 series XL, WS-C35 was handed to me the switch powered up and displayed the ?switch:? prompt.
The switch ?dir flash:? command displayed the following details;
File "xmodem:" successfully copied to "flash:c3500xl-c3h2s-mz.120-5.WC17.bin"
(When you activate the above command and if using HyperTerminal you must immediately select Transfer, then Send File and the name of the IOS image file from the HyperTerminal menu bar.)
I used Microsoft?s HyperTerminal version 5.1 to access the switch via its console port.
When configuring a switch to save having to type in each new long command into HyperTerminal I used the facility of Microsoft Word to previously save then copy and paste these command(s) from within a Word document into HyperTerminal.
You may also copy and paste information displayed in a HyperTerminal session into a Word document too.
The switch ?copy xmodem: flash:? command has a space on either side of ?xmodem:? parameter.
Xmodem transfer is a very slow procedure.
I down loaded a new Cisco IOS image file by using the following link which then directed my self to another page;
