Hub Problems and Solutions
Note: Hub hardware failure is not likely, if it has passed its self-test at startup or reset
• After changing hub configuration, part of
the network does not work.
Restore hub to the initial factory settings (see
“Default Settings” in this manual. Make
changes one at a time and check network
performance after each change.
• Link Integrity is enabled on a port
connected to a pre-10Base-T device.
Disable Link Integrity on that port through
AsantéView (Port Control window) or a local
terminal.
• Other workstations connected to the hub
are disrupting communication of
workstations being brought up.
Remove the disrupting workstations, or
disable (partition) their links through
AsantéView (Port Control window) or a local
terminal.
• Fan has failed. The fan should be running while power is on.
• Miscellaneous problems; you want to run
hub diagnostics.
Reset the hub. This does not affect traffic. Use
a narrow tool (or paper clip) to push the reset
button.
Traffic Patterns
• General network performance degradation
or abnormal statistical indications.
An erratic network traffic pattern (high traffic,
low traffic. Plan network usage so that bursts
of traffic do not occur.
