The following table shows the performance characteristics of the NOE771xx’s
MODBUS/TCP Server.
NOTE: NOE771xx MODBUS/TCP performance measurements are made with

FTP and HTTP Server
The following information describes services provided by the FTP and HTTP
servers.
FTP Server
The NOE771xx’s File Transfer Protocol (FTP) Server is available as soon as the
module receives an IP address. Any FTP client can log on to the module, if the client
uses the correct user name and password.
The FTP Server provides the following services:
z Update the NOE’s firmware by downloading a new Exec
z Provides error log visibility by uploading error log files
z Upload/download BOOTP Server and SNMP configuration files
The default user name is USER, and the default password is USERUSER. Both the
user name and password are case sensitive. Refer to the Quantum NOE 771 xx
Ethernet Modules User Guide for instructions about how to change the password,
and how to add or delete user names to the FTP Server.
There should be only one FTP client per module.
HTTP Server
The NOE771xx’s HyperText Transport Protocol (HTTP) Server is available as soon
as the module receives an IP address. It can be used with version 4.0 or greater of
either the Internet Explorer or Netscape browser.
