Installation IP Configuration The AT-HDR-SW-51 is shipped with DHCP enabled. Once connected to a network, the DHCP server (if available), will automatically assign an IP address to the unit. If the AT-HDR-SW-51 is unable to detect a DHCP server within 15 seconds, then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx/16.
Installation Using the Web Server The IP mode of the AT-HDR-SW-51 can also be set using the built-in web server. In order to access the web server, the IP address of the AT-HDR-SW-51 must be known. 1. Open the desired web browser and enter the IP address of the AT-HDR-SW-51. 2.
Installation • Setting DHCP mode 1. Connect to the AT-HDR-SW-51 using RS-232 or Telnet. 2. At the command line, execute the IPDHCP command using the on argument, as shown.
