SRX345 Installation Overview

 

SRX345 Services Gateway Installation Overview

After you have prepared the site for installation and unpacked the SRX345 Services Gateway, you are ready to install the device. It is important to proceed through the installation process in the following order:

  1. Review the safety guidelines explained in General Electrical Safety Guidelines and Warnings.
  2. Prepare the services gateway for installation as described in Preparing the SRX345 Services Gateway for Rack-Mount Installation.
  3. Install the services gateway as described in Installing the SRX345 Services Gateway into a Rack.
  4. Connect cables to external devices.
  5. Connect the grounding cable as described in Connecting the SRX345 Services Gateway Grounding Cable.
  6. Power on the services gateway as described in Powering On the SRX345 Services Gateway.

SRX345 Services Gateway Autoinstallation Overview

The autoinstallation process begins any time a services gateway is powered on and cannot locate a valid configuration file in the internal 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 internal flash. The autoinstallation feature enables you to deploy multiple services gateways from a central location in the network.

If you are setting up many devices, autoinstallation can help automate the configuration process by loading configuration files onto new or existing devices automatically over the network. You can use either the J-Web interface or the CLI to configure a device for autoinstallation.

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 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.

Note

If the USB autoinstallation feature is enabled (the default configuration), removal of a USB storage device immediately after insertion is not supported.

After you insert a USB storage device, Junos OS scans the device to check whether it contains the USB autoinstallation file. This process might take up to 50 seconds to complete depending on the quality of the USB storage device and the number and size of the files in the device. Removing the USB storage device while this process is running might cause the services gateway to reboot, the USB port to stop working, and data loss on the USB. We recommend that after inserting a USB storage device, you wait for at least 60 seconds before removing it.

By issuing the set system autoinstallation usb disable command (which disables the USB autoinstallation feature) before you insert the USB device, you can reduce the waiting interval between insertion and removal of a USB storage device from 60 seconds to 20 seconds.
