The Black Box®LB1350A/LB1351A is equipped with either a pair of SC-type connectors ( MM or SM models ) or ST connectors ( MM models only )

Do not remove the protective covers on the fiber connectors until you are ready to connect the fiber optic cables. Power should be connected before attaching the fiber optic cables. When dealing with fiber optic cables, it is essential to ensure that the TX at one end of the link is connected to the RX at the other end of the link. Some duplex fiber optic cables are color coded to help monitor the direction of data transmission. If the fibers are not coded, special attention must be paid to ensure a proper connection.

CAUTION

11 - TWISTED PAIR CABLE CONNECTION

As each of the Black Box®LB1350A/LB1351A RJ-45 4(3) ports supports: full auto- negotiation, auto-polarity and auto-cross, you can simply connect any device to any port by using a standard straight or crossed cable. You may need to force an operation mode other than auto-negotiation; refer to section 12 ( “ Configuration Switches “ page 14 ).

Use a shielded Cable Type 5 or higher grade, up to 100m (330ft) long to ensure proper operation at 100Mbps.

On Black Box®LB1350A/LB1351A with the Auto-Cross feature, the RJ45 port has the intelligence to sense the type of cable which has been connected to it and will automatically configure itself to either MDI or MDI-X mode of operation.
