HP 830 Series Configuration Manual page 78

By default, the aggregate interfaces between the access controller engine and the switching engine on
an 830 switch are Access interfaces in VLAN 1. When configuring the two aggregate interfaces, make
sure their permitted VLANs are the same. HP also recommends setting their link type to be the same.

Configuration procedure
In this example, the PC and the AC can reach each other.
1. Configure the PC (TFTP server):
Enable the TFTP server. (Details not shown.)
Configure a TFTP working directory. (Details not shown.)
2. Configure the AC (TFTP client):
# Examine the storage medium of the AC. If the free space is insufficient, use the
delete/unreserved file-url command to delete unused files. (Details not shown.)
# Download system software image file newest.bin from the PC.
<AC> tftp 1.2.1.1 get newest.bin
# Upload a configuration file config.cfg to the TFTP server.
<AC> tftp 1.2.1.1 put config.cfg configback.cfg
# Specify newest.bin as the main system software image file for the next startup.
<AC> boot-loader file newest.bin main
IMPORTANT:
The system software image file used for the next startup must be saved in the root directory of the storage
medium. You can copy or move a file to the Flash root directory.
# Reboot the AC and the software is upgraded.
<AC> reboot
