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.
# Press the Reset button so the switch can run self-diagnostics.
Use Omega to run diagnostics and read statistics. Refer to AT-S20
User’s Guide, Chapter 5, Diagnostics, and Chapter 3, Statistics:
Received and Transmitted Ethernet Frames, for further details
concerning Omega.
# If the management software has failed, check the LEDs to see
if the switch continues to forward packets. Then, at a
convenient time, reboot the switch by pressing the Reset
button or power OFF/ON the switch.
# If problems still persist, for example, the Fault LED remains on,
contact Allied Telesyn’s Technical Support or visit Allied
