Cabling 1000BASE-SX Ports To cable one of the 1000BASE-SX ports with SC connectors: 1 Read the Caution at the beginning of "Cabling Gigabit Ethernet Ports" earlier in this chapter. 2 Remove the dust covers and save them for future use. 3 Examine the port and connector pair for dust. Verify that nothing blocks the light transmission between the port and its connectors. 4 Attach one male connector of the SC cable connector pair to the right side of a fixed Gigabit Ethernet port. 5 Attach the remaining connector of the SC cable connector pair to the left side of the Gigabit Ethernet port. 6 To cable another port, repeat steps 1 through 4. When you cable GBIC transceivers, notice that the SC Receive (RX) port is on the left and the SC Transmit (TX) port is on the right. See Figure 9.
