6: Setup Mode: Server Configuration

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 XX.XX.XX.XX (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: 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).

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).
