B-4 APPENDIX B: REMOTE SOFTWARE UP/DOWNLOADING PROCEDURES
Telnet This method allows you to telnet into the target AccessBuilder’s
command line user interface as a superuser and issue the "load"
command to perform the desired transfer function. Although you telnet
into the AccessBuilder, the load command uses TFTP as the transfer
mechanism (requires a TFTP server to be available for either the upload
or download functions). The IP address of the TFTP server and the
target AccessBuilder must be known, as well as the SuperUser
password for the AccessBuilder.

The header file name selected dictates the action that occurs (direction
of flow). Refer to Table B-1 for filenames.
Telnet Procedures Be sure you have set up a TFTP server. Refer to Table B-1 for filenames.
CAUTION: Whenever an image or configuration file download transfer
occurs, the remote AccessBuilder suspends any user session in progress
and automatically resets upon completion, thus disconnecting any
active users. For this reason, maintenance downloads should be
announced to the system users well in advance of the event, and
scheduled at a time that minimizes network disruption.

AccessBuilder distribution diskette to the TFTP host's TFTP directory.
