Troubleshooting

At the First Sign of a Problem
Perform the following tasks when you first become aware of a problem
with the switch:
# Make sure the power cord is securely connected and the power
voltage is not fluctuating.
# Check the data cables for secure connections and make sure the
device at the other end of a connection is operational.
# Use Omega to read statistics and run diagnostics. For instructions,
refer to the AT-S24 Management Software User’s Guide.
# If the management software has failed, check the port LEDs to see
if the switch is continuing to forward packets. If the switch is
forwarding packets, wait for a convenient time and then reboot
the switch by pressing RESET; or power ON and OFF the switch by
disconnecting and reconnecting the power cord.
Note
Resetting the switch will clear all performance and error statistics
# If the switch is no longer forwarding packets, press the RESET
button so the switch can run self-diagnostics.
# If the problem persists, call Allied Telesyn’s Technical Support or
