Use another system (4500) to add the new IOS to a flash card, then insert it back in the 4510R you are upgrading. If the flash card is in slot0: then from rommon enter the following;

rommon > boot slot0:<new_ios_image_here>

If you do not have another 4500 you may have to do this from xmodem, this could take aawhile;

Hello,

Thanks for the quick answer.

The rommon bios doesn't recognized the tftpdnld command.

I think ( because didn't tryed yet ) it will accept the dnld command.

I think this command will download the image using the rs232 interface. How do i prepare the rommon to use the dnld command and the TFTP Server ( my laptop with solarwinds ) ?

Hmmm... what version rommon are you using?
One other thing - try the tftpdnld command several times - sometimes rommon is funny and doesn't take it the first few times.
Cheers!

I have tryed that. Doesn't work. I read it that if i do a reboot it will download the IOS..

rommon 2 >IP_ADDRESS=10.255.0.18
rommon 3 >IP_SUBNET_MASK=255.255.0.0
rommon 4 >TFTP_SERVER=10.255.0.17
rommon 5 >TFTP_FILE=cat4500-ipbase-mz.122-46.SG.bin
rommon 6 >tftpdnld

 monitor: command "tftpdnld"  not found
rommon 7 >TFTPDNLD

 monitor: command "TFTPDNLD"  not found
rommon 8 >tftpdnld

 monitor: command "tftpdnld"  not found

I'm connecting to one supervisor with a console cable and to the management ethernet port to my laptop that have the TFTP server. Is this the correct procedure ?

That definitely sounds like the right procedure...
If you have active SmartNET, contact Cisco TAC and ask for a rommon upgrade for your sups.
Cheers!

And using the Xmodem command ?

CERTIFIED EXPERT

Commented:
I suppose you could try using the xmodem command, but I'll tell you right now that tftpdnld should be supported on a 12.2 rommon image bootstrap... It's worked ever since 12.0... there's no reason it shouldn't work on your sup.
