Master Troubleshooting Process
Introduction
Use this Master Troubleshooting Process if one or more of your PortServer devices are not
functioning.
Note: This procedure assumes that you are not using the Digi RealPort driver to control your
PortServer ports. RealPort is software that can be installed on one or more host servers to provide
local serial port functionality.
In many of the steps, you will be sent to another procedure that you need to complete. Once you
have completed the procedure, continue with where you left off in the master troubleshooting
process. Otherwise, you might be directed to contact Digi Technical Support.
