is ON
This might indicate problems with the network management
software, such as:
# Unsuccessful software downloads
# Loose RS232 interface connection
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 System 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 ( System
administration>Diagnostics ).
5. Contact Allied Telesyn’s technical support.
