Troubleshooting

If a fiber connection cannot be established, perform the following to make sure that
the fiber transceivers on the IE-MultiWay are not over/under driving the fiber
receivers:
1. Make sure the fiber wavelength on both connected devices match (i.e. both are
1310 nm single-mode fiber).
2. Make sure the twisted-pair port speed on the IE-MultiWay matches that of the
end devices connected to the IE-MultiWay. Configure the IE-MultiWay and its
link partner to Auto Negotiation or, if using Force mode, be sure speed and
duplex match.
3. IE-MultiWay allows the end user to assign a VLAN tag to all management traffic
(SNMP and telnet). It is important to understand that IF using telnet or iView
assign a VLAN tag to management traffic then as soon as this setting is saved the
connectivity will be lost until the PC becomes a member of the VLAN which was
assigned to management traffic.
If a VLAN tag has been assigned to management traffic and the end user cannot
re-establish a connection to the device via iView
to the device via the serial cable and review/modify the changes made (reference
section on serial port config).
