An unrecoverable Ethernet fault (reported as event code 433) is indicated. The event
code is not reported to the switch Event Log or the embedded web server event log,
and must be verified through the switch maintenance port. A maintenance terminal
(desktop or notebook PC) and asynchronous RS-232 modem cable are required to
verify the reporting of event code 433. Both tools are provided by installation or
service personnel. To verify the event code:
a. Remove the protective cap from the 9-pin maintenance port at the rear of the
switch (a flat-tip screwdriver may be required). Connect one end of the RS-232
modem cable to the port.
b. Connect the other cable end to a 9-pin communication port (COM1 or COM2) at
the rear of the maintenance terminal PC.
c. Power on the maintenance terminal. After the PC powers on, the Windows
desktop displays.
d. At the Windows desktop, click the Windows Start button. The Windows
Workstation menu displays.
NOTE: The following steps describe inspecting event code 433 using HyperTerminal serial
communication software.
e. At the Windows Workstation menu, sequentially select Programs, Accessories,
and HyperTerminal. The Connection Description dialog box displays.
