7. Check that network traffic can be routed between the workstation and
the frame.
a. If the workstation supports a network ping, ping the frame. For
example, using Windows NT:
Open a command prompt (DOS window)
In the DOS window, enter:
C:\> PING FRAME'S IP ADDRESS
The results will indicate if the ping reached the frame.
b. If the workstation does not support a network ping, ping the
workstation for the frame serial interface:
In the frame serial command window, enter:
->PING "WORKSTATION'S IP ADDRESS"
The workstation's IP address must be inside the double quotes. The
results will indicate if the ping reached the workstation.
c. If the network ping failed, there may be a network problem
between the frame and the workstation. To ensure it is not the
frame, check the frame with a point-to-point connection:
Using a crossover Ethernet cable, connect the frame directly to a
workstation. The workstation should be assigned an IP Address on
the same Subnet as the frame. Attempt to load the frame's web page
from a Browser on this workstation.
8. If the point-to-point connection attempt fails call Customer Service. If
the point-to-point connection attempt succeeds, the problem is
somewhere in the network between the original workstation and the
frame.
a. Check the connectivity to the frame from different locations in the
network to attempt to isolate physical disconnect problems.
b. Check the connectivity to the frame from inside and outside the
frame's subnet to isolate IP Gateway routing problems.
