Troubleshooting

If a fiber connection cannot be established, perform the following steps to confirm

that the fiber transceivers on the Mini FiberLinX-II are not over- or under-driving the

fiber receivers:

1 Make sure that 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 a Mini

FiberLinX-II to another IMC Networks media converter with the FiberAlert

feature.

3 Make sure that the twisted-pair port speed on the Mini FiberLinX-II matches that

of the end devices connected to the Mini FiberLinX-II. Configure the Mini

FiberLinX-II and its link partner to Auto-Negotiation or, if using Force mode, be

sure that the 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 Mini FiberLinX-II as a powered device, establish power first,

check the LEDs to confirm, and then connect the serial port to configure the

device via a console session.

Note: If you perform these steps in reverse order, the unit will appear non-

functional. The same is true if connecting a DC terminal block.

To Restore Factory Defaults

To restore the unit to factory default settings, use the cleandb function from the

serial port management feature.
