Appendix D:Booting from the Network
If you're experiencing issues with your appliance, you can perform a Netboot Recovery and load
new factory default appliance firmware or restore a previously saved backup image file to the
appliance.
The Netboot Recovery file can be obtained from Avocent Technical Support and it must be placed
onto an FTPserver in order for the Netboot Recovery process to function. Abackup image file can
also be supplied as the Netboot Recovery file on the FTPserver.
To perform a Netboot Recovery:
1. Turn on or reboot the appliance.
2. Select Netboot Recovery.
3. Enter udhcpc to request a DHCP address for the appliance via GB1 (eth0).
-or-
If a static IP needs to be assigned to either GB1 (eth0) or GB2 (eth1), enter the following
command:
NETBOOT> ifconfig eth<x> <IP address> NETBOOT> route add default gw
<gateway_ip> eth<x>
4. After the appliance has been assigned an IP [and optional gateway], the firmware can be
downloaded by entering the following command:
NETBOOT> nboot ftp://<username>:<password>@<ftp server>/<path/filename>.
