Why Compact Flash Recovery Might Be Necessary

For media redundancy, we recommend that you keep a secondary storage medium attached and updated at all times. Use the request system snapshot command to perform the update. (For instructions, see the JUNOS Software Administration Guide.)

If the internal compact flash fails at startup, the Services Router automatically boots itself from the external compact flash or USB storage device. When a redundant storage medium is not available, the router is unable to boot and does not come back online. This situation can occur if the power fails during a JUNOS Enhanced Services upgrade and the physical or logical storage media on the router are corrupted.

If the primary storage medium becomes corrupted and no secondary medium is in place, you can reload the JUNOS Enhanced Services image onto the corrupted compact flash with a desktop or laptop computer running either a UNIX, Microsoft Windows 2000, or Windows XP operating system.

Caution: This procedure does not recover any router configuration files. After you reinstall JUNOS Enhanced Services, all the information on the original internal compact flash is lost.
