ras-1is image 2.

 

 

 

You can store up to two images, or firmware files of the same device model, on the Switch. Only one image is used at a time.

•Run the boot image <12> command to specify which image is updated when firmware is loaded using the web configurator and to specify which image is loaded when the Switch starts up.

•You can also use FTP commands to upload firmware to any image.

The Switch supports dual firmware images, ras-0and ras-1. You can switch from one to the other by using the boot image <index> command, where <index> is 1 (ras-0) or 2 (ras-1). See the CLI Reference Guide for more information about using commands. The system does not reboot after it switches from one image to the other.

44.8.1.1 Example FTP Commands

ftp> put firmware.bin ras-0

This is a sample FTP session showing the transfer of the computer file "firmware.bin" to the Switch.

ftp> get config config.cfg

This is a sample FTP session saving the current configuration to a file called “config.cfg” on your computer.

If your (T)FTP client does not allow you to have a destination filename different than the source, you will need to rename them as the Switch only recognizes “config”, “ras-0”, and “ras-1”. Be sure you keep unaltered copies of both files for later use.

Be sure to upload the correct model firmware as uploading the wrong model firmware may damage your device.
