DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual 
clients to obtain TCP/IP configuration at start-up from a server. You can configure the Prestige 
as a DHCP server or disable it. When configured as a server, the Prestige provides the TCP/IP 
configuration for the clients. If set to None, DHCP service will be disabled and you must have 
another DHCP server on your LAN, or else the computer must be manually configured.

Use the upgrade tool file with a *.exe extension  found in the ZIP file and follow the 
steps to begin the firmware upgrade.
17.4.1  Preparing your Prestige for Firmware Upload
1Change the login password of the Prestige to the factory default password of “1234”.
2Change the IP address of the Prestige to the factory default IP address of “192.168.1.1” 
and make sure that your computer can connect to the Prestige.
• If your computer’s IP address is dynamically assigned by the 
Prestige, release your computer’s IP address and renew it.
• If your computer’s IP address is statically assigned, make sure that 
the IP address is in the same subnet as the Prestige, for example: set 
your computer’s IP address to 192.168.1.33.
3Logout of the Prestige.
