Configuring External CompactFlash on SRX650 Services Gateways

The SRX650 Services Gateway includes 2 GB CompactFlash (CF) storage devices as listed below:

• The Services and Routing Engine (SRE) contains a hot-pluggable Compact Flash (external compact flash) storage device used to upload and download files.
• The chassis contains an internal compact flash used to store the operating system.

By default, only internal compact flash is enabled and an option to take a snapshot of the configuration from internal compact flash to external compact flash is not supported. This can be done only by using a USB storage device.

To take snapshot on external compact flash:

1. Take snapshot from internal compact flash to USB using request system snapshot media usb CLI command.
2. Reboot the device from USB using the command request system reboot media usb.
3. Go to the U-boot prompt. See Accessing the U-Boot Prompt.
4. Stop at U-boot and set following variables:

   set ext.cf.pref 1
      save
      reset
   

5. Once the system is booted from USB, take snapshot on external compact flash using the command request system snapshot media external.

   Note: Once the snapshot is taken on external compact flash, it is recommended to set the ext.cf.pref to 0 in U-boot prompt.
