Configuring the Unit
4.9 Security Settings
Note: You can change these settings via Telnet or serial connections only, not on the Web-
Manager. We recommend that you set security over the dedicated network or over the serial
setup. If you set parameters over the network (Telnet 9999), someone else could capture
these settings.
Disable SNMP (N)
SNMP Community Name (public):
Disable Telnet Setup (N)
Disable TFTP Firmware Update (N)
Disable Port 77FEh (N)
Disable Web Server (N)
Disable ECHO ports (Y)
Enable Encryption (N)
Enable Enhanced Password (N)
4.9.1 Disable SNMP
This setting allows you to disable the SNMP protocol on the unit for security reasons.
4.9.2 SNMP Community Name
This option allows you to change the SNMP Community Name on the unit. This allows for
ease of management, and possibly some security. If someone tries to violate security but
doesn’t know what community to connect to, that person will be unable to get the SNMP
community information from the unit. The name is a string of 1 to 13 characters plus a null-
terminator (14 bytes total). The default setting is public.
4.9.3 Disable Telnet Setup
This setting defaults to the N (No) option. The Y (Yes) option disables access to this
Configuration Menu by Telnet (port 9999). It only allows access locally via the Web pages
and the serial port of the unit.
4.9.4 Disable TFTP Firmware Upgrade
This setting defaults to the N (No) option. The Y (Yes) option disables the use of TFTP to
perform network firmware upgrades. With this option, firmware upgrades can be
downloaded over the serial port using XPort™ Installer’s Recover Firmware procedure.
4.9.5 Disable Port 77FE (Hex)
Port 77FE is a setting that allows XPort™ Installer, Web Pages, and custom programs to
configure the unit remotely. You may wish to disable this capability for security purposes.
The default setting is the N (No) option, which enables remote configuration. You can
configure the unit by using XPort™ Installer, Web pages, Telnet, or serial configuration. The
Y (Yes) option disables remote configuration and Web pages.
Note: The Yes option disables many of the GUI tools for configuring the Device Server,
including the embedded Web Page Configuration tool.
4.9.6 Disable Web Server
This setting defaults to the N (option). The Y (Yes) option disables web server.
