At the First Sign of a Problem

66
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.
# Reset the stack so that the switches can run self-diagnostics.
For instructions, refer to the section Resetting a Stack on
page 3-62.
# Use Omega to read statistics and run diagnostics. Refer to the
AT-S25 Management Software 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, reset the stack, as explained in the section
Resetting a Stack on page 3-62.
# If problems still persist, for example, the Fault LED remains ON,
call Allied Telesyn's Technical Support or visit Allied Telesyn's
web site at www.alliedtelesyn.com.
