Unsuccessful PING options
If the PING was unsuccessful:
1Ensure you have entered the IP address, subnet mask, and default
gateway correctly.
2PING the gateway to see if it responds.
3Contact your data network administrator if the PING still does not work.
ATTENTION! It is possible to successfully PING a device on the network
and still not be able to log on to that device. If you log on to
a device (a Digital Telephone IP Adapter unit) using a
serial connection and neglect to log off, you may be able to
successfully PING the device but be unable to establish a
Telnet connection to it. (The device believes itself to be
busy.)
If you cannot log on to a device after a successful PING,
access the serial port and ensure that you are not logged on to
the device through this port.
