Configuration Via Serial Mode or Telnet Port

Set the Netmask

A netmask defines the number of bits taken from the IP address that are assigned for the host part.

Netmask: Number of Bits for Host Part (0=default) (0) _

The unit prompts for the number of host bits to be entered, then calculates the netmask, which displays in standard decimal-dot notation when the saved parameters are displayed (for example, 255.255.255.0).

Change Telnet Configuration Password

Setting the Telnet configuration password prevents unauthorized access to the setup menu via a Telnet connection to port 9999 or via web pages. The password must have 4 characters.

Change telnet config password (N) ? _

An enhanced password setting (for Telnet access only) of 16 characters is available under option 6 Security from the Change Setup menu.

Note: A password is not required to access the Setup Mode window via a serial connection.

DHCP Name

If a DHCP server has automatically assigned the IP address and network settings, 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 the DHCP name is not changed and the IP is 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.

‹Custom DHCP Name: Create your own DHCP name. If 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 the example).

Change DHCP device name (not set) ? (N) Y

Enter new DHCP device name : LTX

‹Numeric DHCP Name: Change the DHCP name by specifying the last octet of the IP address. When using this method, the DHCP name is LTXYY where YY is the last octet of the IP address. If the IP address specified is 0.0.0.12, then the DHCP name is LTX12. This method only works with 2 digit numbers (0-99).
