Troubleshooting
A network is a complex combination of hardware and software,
all of which must function for data communication to work.
Problems are most likely to occur when the card is first being
installed or when someone changes something in the network. A
problem could be caused in your computer or in cabling or in
many places elsewhere in the network.
If your computer is supported by a system administrator or
network administrator, this person can often provide the most
help in resolving a problem. Allied Telesyn dealers also provide
technical support for installation problems. But if one of these
local resources is not successful solving your problem, you can
obtain assistance directly from Allied Telesyn by fax or by
telephone. See “Where To Find Us” on page 39.
Identify the Exact Symptoms
If your computer is unable to communicate across the network,
carefully observe the symptoms. Gather information about the
system and its components, such as device drivers, memory and
extensions (e.g., QEMM), other peripheral cards and the use of
I/O ports and IRQs. Log your interaction with the computer,
noting the conditions, your actions and the responses. Analyzing
this information will help you diagnose the cause of the failure.
The technical support fax order form on page 40 can help you
organize the information you need to begin resolving a problem.
