I deleted the IOS on a 3750, now I need to use xcopy to reinstall a IOS. I will be loading

c3750-ipservicesk9-mz.122-35.SE5.bin


When I put in the following command:

switch: copy xmodem: flash:c3750-ipservicesk9-mz.122-35.SE5.bin


I get the following result:


Begin the Xmodem or Xmodem-1K transfer now...

CCCCCCCCCCBB0BB0xmodem:: I/O error


Using HyperACCESS and a rool over cable I can communicate with the swich, giving me the following prompt: switch:


I also have access to 3Cdaemon.


Please start from the begining.


Thanks

The better way is to use tftpdnld. It requires that you have a tftp server with the IOS on it. You can get a free server from Kiwi or SolarWinds.

Next, plug the switch into the network using any ethernet port.

Turn on the switch and get to the ROMMON prompt.

Follow the example, this assigns an ip address to the switch, gives it a subnet mask and gateway, and tells it where the IOS is. Use all caps:

rommon 1 > IP_ADDRESS=171.68.171.0

rommon 2 > IP_SUBNET_MASK=255.255.254.0

rommon 3 > DEFAULT_GATEWAY=171.68.170.3

rommon 4 > TFTP_SERVER=171.69.1.129

rommon 5 > TFTP_FILE=c3750-is-mz.12.1.bin

rommon 6 > tftpdnld

Patrick,


Did you initialize the flash before trying the xmodem transfer?


switch: flash_init


then


switch: copy xmodem: flash:c3750-ipservicesk9-mz.122-35.SE5.bin


Also using tftp_dnld is not available on this model switch.


HTH,

Mark
