I found every time I try to boot the 3600 series from a TFTP server, the boot always failed. I can confirm the image name ,the configuration and the connection between the routers and TFTP server are ok. I want to know what is the requirment for booting a 3600 series router from a TFTP server? Thanks

XBOOT (Network Boot) The 3600 series does not have XBOOT software. In order to boot from the network, the 3600 loads the first IOS image in flash and uses this image to boot an image over the network. If you don't have a valid image in flash, you can boot from an image on a PC Card (PCMCIA), or download an image over the console.
If you don't have a valid boot image on bootflash: or Flash card and require to perform this over Console via Xmodem the following are the instructions:
3600 ROMMON Image Download Via Console Port
You can download an image to the 3600 using the console port via the ROMMON command:
xmodem [-cyrx] [filename]
-c use CRC-16
-y use YMODEM protocol
-r copy image to RAM (default is first flash partition)
-x do not launch image on completion of download to DRAM (dangerous!)
Notes:
The ROMMON XMODEM /YMODEM transfer works on the console port only.
You can only download files to the router. You cannot use XMODEM/YMODEM to get files from the router.
Example:
rommon 1 > xmodem -c c3620-i-mz.0918
Do not start the sending program yet...
