What to Do If You Have Problems

This chapter helps you identify and correct problems you may encounter during
and after the installation of the Access Server 316 hardware. The troubleshooting
procedures are for diagnosing and correcting hardware-related problems only.

Notify the network manager if the troubleshooting procedures indicate the
problem is software related or if the procedures do not correct the problem.
Additional software troubleshooting information is provided in the Network
Access Software Problem Solving guide.

Use the following to diagnose and troubleshoot the Access Server 316 problems:

•

Seven-segment display

•

System OK LED

•

Console port messages

A full list of seven-segment display codes are shown at the end of this chapter.
Refer to the Network Access Software Management guide for the procedure to
configure a terminal to receive console port messages.

This chapter includes the following sections:

•
