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,
