Troubleshooting
If a fiber connection cannot be established, perform the following to make sure that
the fiber transceivers on the IE-MiniFiberLinX-II 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 that FiberAlert is enabled on only one unit when connecting an IE-
MiniFiberLinX-II to another IMC Networks media converter with the FiberAlert
feature.
3. Make sure the twisted-pair port speed on the IE-MiniFiberLinX-II matches that of
the end devices connected to the IE-MiniFiberLinX-II. Configure the IE-
MiniFiberLinX-II and its link partner to Auto Negotiation or, if using Force mode,
be sure speed and duplex match.
4. Management (VLAN tagged or Untagged) traffic will not be allowed to pass
through the DATA port and will only pass through the FIBER port.
5. When using the IE-MiniFiberLinX-II as a PD device, establish power first, check
the LEDs to confirm this, and then connect the serial port in order to configure
the device via a console session. If performing the steps in the reverse order, the
unit will appear non functional. The same is true if connecting a DC terminal
block.
To restore the unit to factory default settings, use the cleandb function from the serial
port management feature.
