3.12.4 Change Telnet configuration password

Setting the Telnet configuration password prevents unauthorized access of the setup menu via a Telnet
connection to port 9999 or through Web pages. The password is limited to 4 characters. An enhanced
password setting of 16 characters is available under Security Settings for Telnet access only.
Note: No password is required to access the Setup Mode window via a serial connection.

3.12.5 DHCP Naming

If a DHCP server has automatically assigned the IP address and network settings, you can discover the unit by
using the Device Installer network search feature.
There are 3 methods for assigning DHCP names to these products.
1) Default DHCP name. If you do not change the DHCP name, and you are using an IP of 0.0.0.0, then the
DHCP name will default to CXXXXXX (XXXXXX is the last 6 digits of the MAC address shown on the
label on the bottom/side of the unit). For example, if the MAC address is 00-20-4A-12-34-56, then the
default DHCP name is C123456.
2) Custom DHCP name. You can create your own DHCP name on these products. If you are using an IP
address of 0.0.0.0, then the last option in "Server configuration" will be "Change DHCP device name". The
"Change DHCP device name" option will allow you to change the DHCP name to an alpha-numeric name.
