■100/1000-T xl module ports

■10/100/1000-T xl module ports

Using the above ports:

■If you connect a copper port using a straight-through cable on a switch to a port on another switch or hub that uses MDI-X ports, the switch port automatically operates as an MDI port.

■If you connect a copper port using a straight-through cable on a switch to a port on an end node, such as a server or PC, that uses MDI ports, the switch port automatically operates as an MDI-X port.

ProCurve Auto-MDIX was developed for auto-negotiating devices, and was shared with the IEEE for the development of the IEEE 802.3ab standard. ProCurve Auto-MDIX and the IEEE 802.3ab Auto MDI/MID-X feature are completely compatible. Additionally, ProCurve Auto-MDIX supports operation in forced speed and duplex modes.

If you want more information on this subject please refer to the IEEE 802.3ab Standard Reference.

For more information on MDI-X, refer to the appendix titled “Switch Ports and Network Cables” in the Installation and Getting Started Guide for your switch.

Manual Override. If you require control over the MDI/MDI-X feature you can set the switch to either of two non-default modes:

■Manual MDI

■Manual MDI-X

Table 10-2shows the cabling requirements for the MDI/MDI-X settings.
