Fault LED is ON
This might indicate problems with the AT-S26 management
software, such as:
# An unsuccessful software download
# A failure of the power-on diagnostics
Perform the following steps in sequence; you need not proceed to
the next step if the problem is resolved:
1. Reset the switch either by:
— Pressing the RESET button on the front panel, or
— Selecting
Administration>Reset and restart the
system
from Omega, if you can.
2. Make sure the RS232 connection from the local terminal or PC to
the switch is secure; change the cable if necessary.
If you cannot access
Omega Local
because of a faulty RS232
connection, use
Omega Remote
via Telnet or manage the
switch using SNMP until the problem is fixed.
3. Unplug the switch from the power source, then plug it back in
again.
4. Try to log on to Omega and run diagnostics
(
Administration>Diagnostics
).
5. Download software using the
Administration
menu.
