To update via telnet,
- setup a TFTP server. I used Solarwinds TFTP
- place firmware file at the TFTP's root
- telnet into the switch
2 ways from here,
1. - use the commands,
copy tftp flash TFTPSERVERIP FILENAME.swi primary
reload
2. - type menu
- use arrows to go down to Download OS
- enter the IP of the TFTP server
- enter the filename of the file you placed at the TFTP server's root
- execute
