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.

Twisted-Pair Cable/Connector Pin-OutsThe HP Auto-MDIX Feature In the default configuration, “Auto”, the 10/100Base-TX ports on the 10/100-TX and PoE zl Modules used in the Series 8200zl Switch all automatically detect the type of port on the connected device and operate as either an MDI or MDI-X port, whichever is appropriate. So for any connection, a straight-throughtwisted-pair cable can be used --you no longer have to use crossover cables, although crossover cables can also be used for any of the connections. The 100/1000-T zl Module supports the IEEE 802.3ab standard, which includes the “Auto MDI/MDI-X” feature, which operates the same way.
