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, make 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 2 to
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 2 or telnet, directly connect a PC to the
device via the serial cable and review/modify the changes made (see section on
Serial Port Configuration ).
