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 GL Module that is used in the Series

4100GL 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.

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 GL Module, and the

100/1000-T Transceiver supports the IEEE 802.3ab standard, which includes

the “Auto MDI/MDI-X” feature, which operates the same way.

Note HP Auto-MDIX was developed and shared with the IEEE for the development

of the IEEE 802.3ab standard. HP Auto-MDIX and the IEEE 802.3ab Auto MDI/

MDI-X are completely compatible.

100Base-FX 62.5/125 mm or 50/125 mm (core/cladding) diameter, graded-

index, multimode fiber-optic cables, complying with the

ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a respec-

tively, fitted with MT-RJ connectors

Gigabit-SX 62.5/125 mm or 50/125 mm (core/cladding) diameter, graded-

index, low metal content, multimode fiber-optic cables,

complying with the ITU-T G.651 and ISO/IEC 793-2 Type

A1b or A1a respectively, fitted with SC or LC connectors,

depending on the transceiver used

Gigabit-LX 9/125 mm (core/cladding) diameter, 1310 nm, low metal

content, single mode fiber-optic cables, complying with the

ITU-T G.652 and ISO/IEC 793-2 Type B1 standards, fitted

with SC or LC connectors, depending on the transceiver

used

62.5/125 mm or 50/125 mm (core/cladding) diameter, graded-

index, low metal content, multimode fiber-optic cables,

complying with the ITU-T G.651 and ISO/IEC 793-2 Type

A1b or A1a respectively, fitted with SC or LC connectors

Note: Multimode fiber-optic cabling may be used for a

Gigabit-LX application, but a mode conditioning patch

cord may be needed. See the Installation Guide that came

with your module for more information.
