C Installing and Using TFTP
Overview: What Is TFTP?
TFTP, the Trivial File Transfer Protocol, allows the HP TopTools Remote
Control card to access boot floppy images and new firmware images stored at a
LAN or modem-connected computer. TFTP is built on top of TCP/IP and is
functionally a subset of FTP. As its name indicates, this protocol is used to
transfer data between a "TFTP server" and either the HP TopTools Remote
Control or some other device that acts as the "TFTP client."
NOTE TFTP and the HP TopTools Remote Control card depend on
the TCP/IP protocol. If you are able to view the HP TopTools
Remote Control user interface on your remote computer, this
protocol is already functioning correctly. If not, modification
of either your browser or networking environment may be
required.
HP TopTools Remote Control uses the TFTP service to:
• Access boot floppy images that allow administrators to help diagnose HP
NetServer problems and update the server BIOS.
• Update HP TopTools Remote Control firmware.
TFTP file transfer consists of client-side and server-side components. Because the
HP TopTools Remote Control card has the client TFTP service built into its
firmware, you can use TFTP to transfer either firmware images or boot images
from either a local or a remote computer running a TFTP server program, see
Figure C-1.
