Your Image

The Oracle® Enterprise Session Border Controller arrives with the most recent, manufacturing-approved run-time image installed on the flash memory. If you want to use this image, you can install the Oracle® Enterprise Session Border Controller as specified in the Acme Packet Hardware Installation Guide , establish a connection to the Oracle® Enterprise Session Border Controller, and begin to configure it. On boot up, the system displays information about certain configurations not being present. You can dismiss these displays and begin configuring the Oracle® Enterprise Session Border Controller.

If you want to use an image other than the one installed on the Oracle® Enterprise Session Border Controller when it arrives, you can use the information in this section to obtain and install the image.

Obtaining a New Image

You can download a software image onto the Oracle® Enterprise Session Border Controller platform from the following sources.

• Obtain an image from the SFTP site and directory where you or your Oracle customer support representative placed the image. For example, this may be a special server that you use expressly for images and backups.
• Obtain an image from your Oracle customer support representative, who will transfer it to your system.

Regardless of the source, use SFTP to copy the image from the source to the Oracle® Enterprise Session Border Controller.

Copy an Image to the Oracle® Enterprise Session Border Controller using SFTP

The /boot directory on the Oracle® Enterprise Session Border Controller has 32mb available, and operating system files of approximately 9mb each. Oracle recommends storing no more than two images at a time in this location. One of these should be the latest version. The /boot directory is used for the on-board system flash memory. If you do not put the image in this directory, the Oracle® Enterprise Session Border Controller will not find it.

To copy an image on your Oracle® Enterprise Session Border Controller using SFTP:

1. Go to the directory where the image is located.
2. Check the IP address of the Oracle® Enterprise Session Border Controller’s management port (wancom0). (You might think of this as a management address since it is used in the management of your Oracle® Enterprise Session Border Controller.)
3. Create the connection to the Oracle® Enterprise Session Border Controller.
   There is a wide variety of methods to establish SFTP access to your system. For example, Linux systems allow SFTP operation from a terminal. For a windows system, there are many GUI applications that provide SFTP.
   Using your SFTP application, start an SFTP session to the IPv4 address of the Oracle® Enterprise Session Border Controller management port (wancom0). An SFTP username and SFTP password is required to start the session. The username is always user, and the password is the your User mode login password.
4. Set your SFTP application to copy the image to the /boot folder using binary transfer mode.
5. Invoke and confirm your SFTP file transfer to the device.
6. Boot the Oracle® Enterprise Session Border Controller using the image you just transferred.

   In the ACLI, change any boot configuration parameters that need to be changed. It is especially important to change the filename boot parameter to the filename you used during the SFTP process. Otherwise, your system will not boot properly.

   Alternatively, from the console you can reboot to access the boot prompt and then configure boot parameters from there.

7. In the ACLI, execute the save-config command in order to save your changes.
8. Reboot the Oracle® Enterprise Session Border Controller.
9. The Oracle® Enterprise Session Border Controller runs through its loading processes and returns you to the ACLI logon prompt.

System Image Filename

The system image filename is a name you set for the image. This is also the filename the boot parameters uses when booting your system. This filename must match the filename specified in the boot parameters. When you use it in the boot parameters, it should always start with /boot to signify that the Oracle® Enterprise Session Border Controller is booting from the /boot directory.

If the filename set in the boot parameters does not point to the image you want sent to the Oracle® Enterprise Session Border Controller via SFTP, then you could not only fail to load the appropriate image, but you could also load an image from a different directory or one that is obsolete for your purposes. This results in a boot loop condition that you can fix by stopping the countdown, entering the appropriate filename, and rebooting the Oracle® Enterprise Session Border Controller.
