Upgrading the firmware on HP Procurve switch | integrating IT

https://integratingit.wordpress.com/2014/10/05/upgrading-the-firmware-on-hp-procurve-switch

Upgrading the firmware on HP Procurve switch. October 5, 2014. I have an HP ProCurve 3500-48 POE switch that I wish to upgrade the firmware version on. ProCurve switches come with 2 boot partitions so we can upload the new firmware to the partition not currently in use. In this scenario I have setup a TFTP server (SolarWinds TFTP Server) on the local LAN; I have tested connectivity from the switch by pinging the TFTP server. Determine which partition (primary/secondary) is currently the boot partition.
