3Com 3C18320 Operation , Standards

Operation Power up the chassis or hub. The FDDI MIC Media Module will operate

correctly once power is applied.

Optical Safety Under most normal viewing conditions there is no eye hazard from the Tx

launcher LED. It is recommended however, that the LED is not viewed

through any magnifying device, whilst powered on.

If the FDDI MIC Media Module powers up but no communication is

possible, check that:

■The remote unit is powered on.

■The fiber cable is continuous.

■The connectors are clean.

■If keys not fitted, the orientation of the MIC connectors is correct.

If these checks fail to cure the problem, refer to the supplier of your 3Com

FDDI MIC Media Module for further advice.
