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 Chapter 5,
"Diagnostics," and Chapter 3, "Statistics: Received and
Transmitted Ethernet Frames," in the "AT-S20 User's Guide" for
further details concerning Omega.
If the management software has failed, and the switch
continues to forward packets, when convenient power on/off
or reboot the switch.
If problems still persist, for example, the Fault LED remains on,
call Allied Telesyn's Technical Support or visit Allied Telesyn's
website at www.alliedtelesyn.com.
