12 Troubleshooting
C
Verify the data link Check the Ethernet
LEDs on the PC and
EUM Ethernet
connectors. The Link LED is ON solid
green, and the Traffic
LED is flashing
occasionally with traffic. Cable connection is
good, and the Ethernet
interfaces are active. Go
to Test D.
• Check the type of cable. The cable
between the EUM and PC should be a
crossover cable.
• Check connector pins. Make sure none
of the pins have been damaged.
• Check for a pinched cable.
• Check for possible hardware problems
at the PC.
• Change to a different PC, with a shorter
cable.
• If none of the above resolves the
problem, you might suspect a defective
EUM.
D
Verify the logical data
connection between the
PC and EUM Through the DOS
command line on the
end-user’s PC,
<ping>
the EUM with short and
long packets.
No failures or time-outs. Confirms the physical
and logical connection to
the EUM, and basic IP
addressing. Go to Test
E.
• Verify the IP address in the PC, by
entering
<ipconfig>
in the DOS
command line. If the IP is bad, enter the
appropriate IP set (PC’s IP, gateway IP,
and DNS IP).
• If using DHCP, renew through
<ipconfig>
.
• If DHCP fails, enter a valid IP set for
remaining tests
• Change to a different PC, using shorter
cable.
• If none of the above resolve the reported
problem, you might suspect a defective
EUM.
E
Through the DOS
command line on the
end-user’s PC,
<ping>
the CCU with short and
long packets.
No failures or time-outs. Confirms data
transmission over the
radio link, and completes
the 900MHz network-
specific troubleshooting.
Go to Test F. If no pings are successful:
• Verify the EUM ID in the CCU
Authorization Table.
• Reboot the EUM.
• Reboot the PC.
• Refer to
If You Have an Interferer on
page 149.
If pings are successful but have errors:
• Refer to If You Have an Interferer on
page 149.
