RECOVERING SOFTWARE
This recovery process returns the Campus-REX2 to a working state after a file system failure. If, upon bootup of the Campus-REX2, it is determined that the file system is corrupted, the unit performs the process described below. The potential for file system failure occurs if the unit loses power during a code upgrade or during a configuration save.
For the recovery to occur, you must have the following installed and available to the Campus-REX2:
•A BOOTP server must be configured and available to respond to the MAC address of the Campus-REX2 with the following information:
–IP address and subnet mask
–Gateway IP address, if required
–TFTP server IP address
–recovery image filename
•A TFTP server must be active and available and contain the recovery image file (name provided to Campus-REX2 by BOOTP server).
The Campus-REX2 automatically performs the following when recovering software:
1After internal processing, the Campus-REX2 sends a BOOTP request out both the LINE and LAN interfaces. These requests are transmitted until a reply is received.
2After the BOOTP response is received by the Campus-REX2, it attempts to download code from the TFTP server (TFTP server IP address provided to Campus-REX2 by BOOTP server).
3After the new image is downloaded, the Campus-REX2 automatically boots the new image.
Your Campus-REX2 is now in a normal operating state and you can manage it as appropriate.
