Configuring Remote Access for AN and Passport ARN Routers
B-18 308614-14.20 Rev 00
Restoring a Local File System
If the AN/ANH or ARN router’s local file system becomes corrupted, you must
restore it by upgrading the software image.
If the router resets, reboots, or loses power while restoring or compacting its flash
memory card, it automatically netboots the configuration file and software image.
(You must already have the network set up for Netboot or Directed Netboot to
succeed.)
After the router netboots successfully, you can use TFTP to restore the software
image and configuration file on the local file system.
Note: If the AN/ANH or ARN router reboots while writing to or compacting
partitioned flash memory, the file system becomes corrupted and the router
will not start after rebooting.
Caution: Compacting the file system on a flash mem ory card can take up to
15 minutes. When you compact an AN/ANH or ARN router’s file system,
allow the compaction to complete before resetting the router.
