As I spend a good hour trying to figure out how to upgrade an AP through the console port in apboot mode. Although I could find bits and pieces searching the web and this forum it took me some time to figure it out. Below the steps:
Step 1: Hit <Enter> to stop autoboot: 0
enter
Step 2: Set Static IP address
setenv ipaddr 10.254.254.7
Step 3: Set subnet mask
setenv netmask 255.255.255.0
Step 4: Set next hop
setenv gatewayip 10.254.254.1
Step 5: Set boot parameter to TFTP
setenv bootcmd tftpboot
Step 6: Set IP address of TFTP server
setenv serverip 192.168.25.250
Step 7: Print your settings to validate
printenv
Step 8: Upgrade the OS replace OS file with whatever you require
upgrade os ArubaOS_Draco_10.4.1.3_90100
Reload and you are done
Below an old article, which did only partially suffice for me
