6-24 July 2004 Wide Bank 28 DS3 - Release 2.4

Figure 6-3C: A NetworkValet management session connected to the Ethernet, and the Ethernet
port on the unit connected to an IP network. The TFTP server on which the new level of firmware
resides must be reachable through an IP network as well, and you must know the IP addresses for
both the Wide Bank and the server.
 An SNMP session connected to the Ethernet, and the Ethernet port on the Wide Bank connected
to an IP network. A TFTP download is initiated via SNMP using the enterprise MIB.
 An SNMP or Telnet session operating via the DS3 PPP link. The PPP link must be active and the
device on the other end of the PPP link must be connected to an IP network.
Protocol Options for Downloading Firmware
The protocol options for downloading software are:
 Xmodem protocol: This protocol can be used when the management PC is connected to the
RS-232 port of the unit (Figure 6-3A) and the new control code resides on the same
(management) PC.
 Trivial File Transfer Protocol (TFTP): This protocol can be used when the management PC
is connected to either the RS-232 port in which file transfer occurs over the Ethernet port
(Figure 6-3B) or is connected with a Telnet session through the Ethernet port (Figure 6-3C).
There must be a TFTP server that can store and transfer the new control code. The TFTP
protocol is usually faster than the Xmodem protocol.
