Switch Ports and Network Cables Twisted-Pair Cable/Connector Pin-Outs Installing the Patch Cord As shown in the illustration below, connect the patch cord to the Gigabit-LX mini-GBIC with the section of single-mode fiber plugged in to the Tx (transmit) port. Then, connect the other end of the patch cord to your network cabling patch panel, or directly to the network multimode fiber. If you connect the patch cord directly to the network cabling, you may need to install a female-to-female adapter to allow the cables to be connected together.

In the default configuration, "Auto", the 10/100Base-TX ports on the 10/100-TX and PoE xl Modules used in the Series 5400zl Switches all automatically detect the type of port on the connected device and operate as either an MDI or MDI-X port, whichever is appropriate.

Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the Gigabit-LX
mini-GBIC with the section of single-mode fiber plugged in to the Tx (transmit)
port. Then, connect the other end of the patch cord to your network cabling
patch panel, or directly to the network multimode fiber.
If you connect the patch cord directly to the network cabling, you may need
to install a
female-to-female adapter
to allow the cables to be connected
together.

Mode Conditioning Patch Cord
Make sure you purchase a patch cord that has LC connectors on the end that
connects to the Gigabit-LX mini-GBIC, and has multimode fibers that match
the characteristics of the multimode fiber in your network.
