SRX 210 Services Gateway Autoinstallation Overview
Autoinstallation provides automatic configuration for a new services gateway that you connect to the network and turn on, or for a services gateway configured for autoinstallation. The autoinstallation process begins anytime a services gateway is powered on and cannot locate a valid configuration file in the compact flash. Typically, a configuration file is unavailable when a services gateway is powered on for the first time, or if the configuration file is deleted from the compact flash. The autoinstallation feature enables you to deploy multiple services gateways from a central location in the network.
For the autoinstallation process to work, you must store one or more host-specific or default configuration files on a configuration server in the network and have a service available—typically Dynamic Host Configuration Protocol (DHCP)—to assign an IP address to the services gateway.
Autoinstallation takes place automatically when you connect an Ethernet or serial port on a new services gateway to the network and power on the device. To simplify the process, you can explicitly enable autoinstallation on a device and specify a configuration server, an autoinstallation interface, and a protocol for IP address acquisition.
