Let's see .. where to begin.
1- Is this a New i5 system?
2- Can you ping it from the desktop?
3- Is it a direct connect or through at network?
4- Access? Rumba? Mocoa? OpsNav? Telnet?
5- Is i5 IP'd?
6- Can other machines see/run jobs on the i5?
7- Does it already have a console now?
8- Are you replacing the 5250 console with a PC?
9- Will Joanie and Chachie ever get back together?
Otherwise ... your best bet is...
