NOTE: Due to a fault in some Plug-n-Play BIOS programs, if happens occasionally that a newly installed adapter is

assigned an Interrupt Number which is already assigned to another device. In such a case, the conflict of Interrupt Number will cause faults in the behavior of both devices. Then it is necessary to run the CMOS Setup utility and manually assign a non-conflicting Interrupt Number.

Multimode (62.5/125pm or 50/125um) fiber cabling with an IEEE recommended SC connector is required for the adapter. Use either one duplex SC connector, or two simplex SC connectors, and observe the correct relationship between the receive (Rx) and transmit (TX) ports on the adapter and repeater. If there is a need to monitor the adapter faceplate LEDs, make the rear of the PC or workstation accessible and leave sufficient clearance for cabling and service.
