Troubleshooting a TCP/IP Network Using A Ping Utility
(Enter the appropriate information where indicated by the quotation marks below. Do not enter the quota- tion marks.)
To see if a unit in your network can be reached, try to ping your unit by typing the following command in a DOS window:
c:\>ping ‘unit IP address’
If it is reached, there will be a response like the following:
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the LAN path is malfunctioning, the ping command will time out. If so, you could have one of the following problems:
•Wrong physical connections. Make sure the LAN Link LED is on. See the Basic Functioning section above for more information.
•Wrong network connection. Verify the IP address is entered correctly and that subnet mask and gate- way address are set properly.
Otherwise, ask your network administrator.
