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.
Figure B-1. 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.
Twisted-Pair Cable/Connector Pin-Outs
The 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-through twisted-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 oper-
ates the same way.
