Connect the appropriate network cables to the module's ports as shown

in the table on the next page. The table shows the supported cable types

for the 10/100-TX GL Module and the 100/1000-T GL Module. The cabling

that you would use for the transceivers that are installed in the Gigabit

Transceiver GL Module depends on the types of transceivers you are

using. Please see the manual that came with the transceivers for informa-

tion on the appropriate cabling.

For more information on the cable specifications, see "Cables" on page 17.

Automatic Cable Sensing:

When the ports for the 10/100-TX GL Module and the 100/1000-T GL Module

are in their default configuration, Auto, both modules automatically negotiate

whether the ports operate as MDI or MDI-X, depending on the cable type and

the connected device's operation. As a result, you can use either "straight-

through" or "crossover" twisted-pair cable for all network connections to

these modules.

On the 10/100-TX GL Module, this feature is identified as HP Auto-MDIX; on

the 100/1000-T GL Module, it comes with compliance with the IEEE 802.3ab

standard, and is identified as Auto MDI/MDI-X. Both features operate the

same.

Operation of this feature depends on the port configurations being kept at Auto.

If the configuration is changed to one of the available fixed options though

(for example, 100-Full Duplex), the port operates as an MDI-X port. In that

case, to connect the module to another switch or hub, use a crossover cable;

to connect to an end node, use a straight-through cable.
