This means you can use a "straight-through" twisted-pair cable or a "cross
over" twisted-pair cable for any of the connections—the port makes the
necessary adjustments to accommodate either one for correct operation. The
following port types on your switch support the IEEE 802.3ab standard, which
includes the "Auto MDI/MDI-X" feature:
ProCurve Series
ProCurve Series
2600 Switch
2800 Switch
10/100-TX ports
10/100/1000-T ports
10/100/1000-T ports
Using the above ports:
If you connect a copper port using a straight-through cable to a port on
■
another switch or hub that uses MDI-X ports, the switch port automati
cally operates as an MDI port.
■
If you connect a copper port using a straight-through cable 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.
HP Auto-MDIX was developed for auto-negotiating devices, and was shared
with the IEEE for the development of the IEEE 802.3ab standard. HP Auto-
MDIX and the IEEE 802.3ab Auto MDI/MID-X feature are completely compat
ible. Additionally, HP 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 Auto-MDIX Override on the Series 2600/2600-PWR
and 2800 Switches
This feature is supported only on the Series 2600, 2600-PWR, and 2800
Switches. If you require control over the MDI/MDI-X feature you can set the
switch to either of two non-default modes:
Manual MDI
