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:
1 After 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.
2 After 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).
3 After 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.
