Configuring Internal Compact Flash Recovery

To recover an internal compact flash with a corrupt or missing operating system, you must remove the corrupt internal compact from the J-series Services Router, plug it into a PC with a PCMIA adapter or USB card reader, copy the JUNOS recovery software package onto it, and reinstall on the router.

Recovery software packages are available from the same location as J-series upgrade software packages. (See the JUNOS Software Administration Guide.)

To recover an internal compact flash:

1.Plug the compact flash into a PCMCIA adapter or USB card reader.

2.Plug the PCMCIA adapter or USB card reader into the host PC and verify that the compact flash is recognized by the operating system.

3.Select the appropriate recovery software package according to the size of your compact flash. The uncompressed package must have the same size as the target compact flash capacity: 128 MB, 256 MB, 512 MB or 1024 MB. The recovery software package name indicates the size of the package. For information about recovery software package names, see the JUNOS Software Administration Guide.
