Chapter 2 Installation Connecting to 100BASE-FX and 1000BASE-SX Ports Connecting to 100BASE-FX and 1000BASE-SX Ports The 100BASE-FX and 1000BASE-SX ports operate only in full-duplex mode. You can connect a 100BASE-FX or 1000BASE-SX port to an SC or ST port on a target device by using one of the MT-RJ fiber-optic patch cables listed in Table 2-1. Use the Cisco part numbers in Table 2-1 to order the patch cables that you need. Table 2-1 MT-RJ Patch Cables for 100BASE-FX and 1000BASE-SX Connections Type 1-meter, MT-RJ-to-SC multimode cable 3-meter, MT-RJ-to-SC multimode cable 5-meter, MT-RJ-to-SC multimode cable 1-meter, MT-RJ-to-ST multimode cable 3-meter, MT-RJ-to-ST multimode cable 5-meter, MT-RJ-to-ST multimode cable Cisco Part Number CAB-MTRJ-SC-MM-1M CAB-MTRJ-SC-MM-3M CAB-MTRJ-SC-MM-5M CAB-MTRJ-ST-MM-1M CAB-MTRJ-ST-MM-3M CAB-MTRJ-ST-MM-5M Caution Do not remove the dust plugs from the fiber-optic ports or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the fiber-optic ports and cables from contamination and ambient light. Follow these steps to connect the switch to a 100BASE-FX or 1000BASE-SX device: Step 1 Step 2 Remove the dust plugs from the 100BASE-FX or 1000BASE-SX port and the rubber caps from the MT-RJ patch cable. Store them for future use. Insert the cable in a 100BASE-FX or 1000BASE-SX port. (See Figure 2-36.)
