Incorrectly wired or installed cabling is the most common cause of
communications problems for local area networks. HP recommends that you
work with a qualified cable installer for assistance in your cabling
requirements.

CAUTION
The unshielded twisted-pair cables you use with the PCI 10/100Base-TX card
must comply with the IEEE 802.3u 100Base-TX standards in order to meet
emissions requirements. These standards support cabling up to 100 meters
only.

PCI 10/100Base-TX Card Twisted-Pair Connector
The same connector on the card is used for either 10Base-T or 100Base-TX
operation. The operating mode is determined by the setting of the hub or
switch to which the card is connected.
