Hi Experts,

I have a HP Switch and want to upgrade OS to flash.  Currently the SW is not on network.  I want to use my W7 laptop to connect to the console of SW and do tftp uploading via serial-USB cable.  

During upload setting or command line, how can we point or specify the tftp server? Normally we use IP address of tftp server.

I am using tftpd64.  What other tftp server do you suggest?

Thanks

tftp is an IP based service, you cannot use it without IPs.

You should look at x-modem or y-mode serial transfer if you cannot plug into the switch with a network cable.

mattvmotas is correct.

However, since the console is limited to 115kbp/s, transferring the OS this way could take a looooong time. I would simply connect my PC to the switch with an ethernet cable, assign an IP address to the switch and upload the OS using tftp other the 100mbp/s ethernet connection.

The switch comes with USB port.  I am trying to do it with USB, but when I load the OS with copy usb flash K_XX_XXXX, I got "Cannot open dest in Ram error" error.  

Any suggestions?

Thanks

It sounds like you are trying to load an image that is too large for the flash.  Have you already removed the old image?

Isn't it able to overwrite the old one?  How do we remove the old one from the flash?  Thanks

It would only overwrite the old one if they are named the same.  You would get some kind of prompt about that.

You need to use the delete command, not sure what that is on HP, but should be something like delete flash:filename.
