HP Insight Control Server Provisioning 7.2 Administrator Guide

NOTE: The appliance TFTP server required to allow target servers to PXE boot from the appliance
will always run regardless of whether the DHCP server you use is internal or external to the
appliance.
2.1.2 Setting up a DHCP server external to the appliance
The Insight Control server provisioning appliance can support either using the DHCP server internal
to the appliance, or using an external DHCP server set up at your facility.
If you require more control or more features from your DHCP server than are available via the
appliance UI, you should disable the DHCP server on the appliance and configure your own server.
See “Deciding whether to use a DHCP server internal or external to the appliance” (page 10) for
details.
Below are instructions for configuring an external Windows DHCP server or an external Linux ISC
DHCP server.
NOTE: HP recommends setting the lease time on your DHCP server to at least one day to prevent
issues caused by time synchronization.
NOTE: These instructions are for configuring the extended DHCP options required for PXE booting
target servers from the appliance. If you do not require extended options, no special configuration
of your DHCP server is necessary beyond the ability to provide an IP address to target servers and
possibly extending the lease time.
NOTE: If you decide to use an external DHCP server, make sure Service provided by appliance
is set to None on the appliance Settings DHCP page.
NOTE: You can find the deployment IP address on the Settings Appliance page under Deployment
IP.
