Some examples of powerman targets:
Power on hosts bar,baz,foo01,foo02,...,foo05: powerman --on bar baz foo[01-05] 
Power on hosts bar,foo7,foo9,foo10: powerman --on bar,foo[7,9-10] 
Power on foo0,foo4,foo5: powerman --on foo[0,4-5] 
As a reminder to the reader, some shells will interpret brackets ([ and ]) for pattern matching. \
Depending on your shell, it may 
be necessary to enclose ranged lists within quotes. For example, in tcsh, the last example above should...

15.14  Zero Touch Provisioning
Zero Touch Provisioning (ZTP) was introduced with firmware release 3.15 to\
 allow appliances to be provisioned during their 
initial boot from a DHCP server.
15.14.1 Preparation
These are typical steps for configuration over a trusted network:
1. Configure a same-model appliance.
2. Save the configuration as a backup (.opg) file under System: Configuration Backup in the web UI, or via config -e in the 
CLI. Alternatively, you can save...

15.14.4 How it works
This section explains in detail how the Appliance uses DHCP to obtain it\
s initial configuration.
First, an appliance is either configured or unconfigured. ZTP needs \
it to be in an unconfigured state, which is only obtained in 
the following ways:
• Firmware programming at factory
• Pressing the Config Erase button twice during operation
• Selecting Config Erase under System: Administration in the web UI, and rebooting
• Creating the file /etc/config/.init and then rebooting...

• The system checks to see if it is still in an unconfigured state. If i\
t is, then the network interface mode is set to DHCP. This 
effectively forces the system into a configured state, preventing a fu\
ture reboot loop.
• The system reboots
Note: If all the URLs were skipped or failed, the system will wait for 30 sec\
onds before retrying again. It will retry all the URLs 
up to 10 times. After the 10th retry, the system reboots. If the system has been manually...

 Configure lighttpd
