82 Agilent 7697A Troubleshooting
7 Communications
Check the end in the hub/switch and the one in the
network card of the PC or instrument. When properly
connected and working, network cards provide green and
yellow LEDs as a visual indicator of network connectivity.
Look on the back of the NIC adapter of the PC and the
back of the instrument.
• If there is no green LED, there is no connectivity. Look
for a hardware problem such as a disconnected cable,
dead network, defective switch/hub, router, or defective
NIC.
• If there is a red LED lit, there is a problem with the
NIC.
• If the green LED is lit, with a flashing yellow or orange
LED, the network card is properly connected and
working. This condition indicates an active network,
and verifies that the jack in the wall is working.
Disconnect the network cable and confirm that the
network reports it is disconnected. Re- connect the
network cable and confirm the PC reports the connection.
Power cycle the router.
6 Check your firewall settings and make sure that the
firewall is not blocking the incoming and outgoing traffic.
7 You can test to see if the wall jack is having trouble by
plugging your cable into another jack you know is
working. You can also plug another device with a working
network connection, such as a laptop, into the same jack
as the HS.
8 If you see the error message “Service Control Manager
reported an error” when you logon to Windows, this could
indicate a bad NIC card or corrupt software driver for the
NIC card. If this occurs, check the Windows Event Viewer
program for details.
9 Check if the computer's network card is functioning
properly and that TCP/IP is installed correctly as follows:
a Click Start > Run, then type cmd and click OK.
b Type ping 127.0.0.1 and press [Enter]. You should see four
lines that read something like this “Reply from 127.0.0.1:
bytes=32 time<10ms TTL=64”. If you are getting anything
else, there is a problem with your NIC card. Reinstall
the driver of the NIC adapter and if the problem is
still there then change the NIC adapter and reconfigure
it.
