Connecting Fiber Optic Ports
Connect devices to the fiber optic ports as shown in Figure 2-6.
The BayStack 450-12F switch and the 400-4FX MDA are 100BASE-FX devices.
Both products use MT-RJ port connectors with 62.5/125-micron multimode fiber
optic cable. The 400-2FX MDA is also a 100BASE-FX device but uses standard
SC port connectors with 62.5/125 micron multimode fiber optic cable.

The 1000BASE-X MDAs (the 450-1SR/SX and the 450-1LR/LX) and the ATM
MDAs (the 450-2M3 and 450-2S3) use standard SC port connectors but special
consideration is required for 1000BASE-LX connections (see “1000BASE-LX
Multimode Applications” on page C-22).
