LAN Troubleshooting Overview

LAN troubleshooting guidelines follow. However, the first step is to check for

normal operation, as shown in Checking for Normal Operation

Checking for Normal

Operation

Before beginning LAN troubleshooting steps, you should first check to see

what symptoms appear when you attempt to connect to instruments via the

LAN. To see if your PC has network access to an instrument, open the Web

Browser on the PC and type in the instrument’s IP address (or Hostname,

if known) on the web browser’s address line.

If the instrument’s

Welcome Page appears, this PC has network connection

to the instrument. Repeat this step for each instrument on the network.

An example for the Agilent 33220A follows. If normal operation cannot be

established, go to Troubleshooting Flowchart

for a suggested sequence of

troubleshooting steps.
