on the ELS100-24TXG.
Figure 2-6. Inserting a Dual SC Connector into a Port
The 1000Base-X Gigabit Ethernet ports interfac e to differen t media types
depending on the GBIC module installed. The 1000Base-SX standard
over multi-mode fiber uses dual SC fiber connectors. The 1000Base-LX
standard over single mode or multi-mode fiber also uses dual SC fiber
connectors. The dual SC connectors are configured as a receive(RX)/
transmit(TX) pair with the RX connector positioned on the left side of the
port and the TX connector on the right side of the port.
Copper connections are also supported on the Gigabit Ethernet ports.
The 1000Base-CX standard over shielded, balanced copper uses High
Speed Serial Data Connectors (HSSDCs).
