Change Telnet/Web Manager Password
Setting the Telnet/Web Manager password prevents unauthorized access to the setup menu
through a Telnet connection to port 9999 or through web pages. Please protect your device
from unauthorized access and follow the instructions below:
 Always select Y to enable Telnet/Web Manager password
 Enable the enhanced password setting and create a strong 16-character password.
For details, see Security Settings (Option 6) on page 69.
Note: We do not recommend that you only use the 4-character basic password as it
does not offer sufficient security. Using no password is very dangerous.

DHCP Name
If a DHCP server has automatically assigned the IP address and network settings, you can
discover the unit by using the DeviceInstaller network search feature.
There are three methods for assigning DHCP names to the unit.
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 defaults 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. In other words, if you do
nothing and leave the IP address set to 0.0.0.0, the UDS1100 will supply the DHCP name
Cxxxxxx to the DHCP server, where xxxxxx is the last 6 digits of the MAC address.
Custom DHCP Name: You can create your own DHCP name. If you are using an IP
address of 0.0.0.0, then the last option in Server configuration is Change DHCP device
name. This option allows you to change the DHCP name to an alphanumeric name (LTX in
our example). For instance, if you type a 'Y' when asked if you want to change the DHCP
name, you will be prompted for a new DHCP name. The example uses "LTX" as the DHCP
name sent to the DHCP server, but you can type in anything you want, e.g. "Test_Lab",
"Accounting", "Radiology" or any other string you want to use.
Change DHCP device name (not set) ? (N) Y
Enter new DHCP device name : LTX
Numeric DHCP Name: You can change the DHCP name by specifying the last octet of the
IP address. When you use this method, the DHCP name is LTXYY where YY is what you
chose for the last octet of the IP address. If the IP address you specify is 0.0.0.12, then the
DHCP name is LTX12. This method only works with 2 digit numbers (01-99). For instance, if
you specify a two digit number for the last octet of the IP address, leaving the first three
octets set to 0, then the DHCP name will be the name you provided with that number
appended. I.e. if you specify IP address 0.0.0.43 and change the DHCP name to "Test_Lab"
the name the UDS1100 sends to the DHCP server will be "Test_Lab43".
Note that this has no effect on the IP address assigned to the UDS1100 by the DHCP server,
it is only a method to add a two-digit number to the DHCP name specified.
