Troubleshooting
This chapter provides information on how to detect and resolve
problems with your switch.
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 read statistics and run diagnostics. Refer to the
AT-S21 Software Management User’s Guide for further
details on gathering Ethernet statistics and running
diagnostics using the Omega menus.
" 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 Reset; or
power ON and OFF the switch by disconnecting and
reconnecting the power cord.
" 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.
