Connection to the ONS 15454
Step 1 If your computer is already connected to the corporate LAN, go to Step 3. If you changed your 
computer’s network settings for craft access to the ONS 15454, change the settings back to the corporate 
LAN access settings. This generally means:
• Set the IP Address on the TCP/IP dialog box back to Obtain an IP address automatically 
(Windows 98) or Obtain an IP address from a DHCP server (Windows NT 4.0, 2000, or XP). 
• If your LAN requires that Domain Name System (DNS) or Windows Internet Naming Service 
(WINS) be enabled, change the setting on the DNS Configuration or WINS Configuration tab of the 
TCP/IP dialog box. 
Step 2 Connect a straight-through (CAT-5) LAN cable from the PC or Solaris workstation NIC card to a 
corporate LAN port.
Step 3 If your computer is connected to a proxy server, disable proxy service or add the ONS 15454 nodes as 
exceptions. To disable proxy service, complete one of the following tasks, depending on the web 
browser that you use:
• DLP-G43 Disable Proxy Service Using Internet Explorer (Windows), page 2-22
• DLP-G44 Disable Proxy Service Using Netscape (Windows and UNIX), page 2-22
Step 4 Continue with the “NTP-G21 Log into the ONS 15454 GUI” procedure on page 2-24.
Stop. You have completed this procedure.
