I am upgrading the Comware 5 firmware on HP 5120 switches HP 5120-48G-PoE+ EI Switch Product # JG237A. In the past I have upgraded them with they are offline. I would use my laptop as a TFTP server, connect it to a port on the switch, and put my laptop IP address and switch management IP address on the same subnet. I would use the following commands (for example):
delete /unreserved flash:/<firmware>
tftp <IP Address> put flash:/<firmware>
boot-loader file flash:/<firmware>
Would I be able to do this with a live HP 5120 switch connected to the production network and grab the firmware off a live tftp server on the production network?
Please help. Thank you.
