7.Make sure that the transmit and receive cables are:

❑Clearly marked or color coded.

❑Connected to the appropriate ports on the 10BASE-FL Module.

❑Properly cleaned with an appropriate fiber optic cleaning solution before installation.

Note: Do not exceed the bend radius for the fiber cable when directing the cables under the concentrator. Refer to the cable manufacturer's specifications for minimum bend radius.

8.Attach the other ends of the cables to either:

❑Another ONline 10BASE-FL Module.

❑An ONline 10BASE-FL Transceiver.
