Using the Business Policy Switch 2000 Version 2.0
The 10BASE-T/100BASE-TX port connectors are configured as MDI-X
(media-dependent interface-crossover). These ports connect over straight cables
to the network interface card (NIC) in a node or server, similar to a conventional
Ethernet repeater hub. If you are connecting to an Ethernet hub or Ethernet switch,
use a crossover cable unless an MDI connection exists on the associated port of
the attached device (see “Appendixes).
The Business Policy Switch uses autosensing ports designed to operate at 10 Mb/s
(megabits per second) or at 100 Mb/s, depending on the connecting device. These
ports support the IEEE 802.3u autonegotiation standard, which means that when a
port is connected to another device that also supports the IEEE 802.3u standard,
the two devices negotiate the best speed and duplex mode.
The 10BASE-T/100BASE-TX switch ports also support half- and full-duplex
mode operation (refer to
Installing the Business Policy Switch 2000 ).
The 10BASE-T/100BASE-TX RJ-45 ports can connect to 10 Mb/s or 100 Mb/s
Ethernet segments or nodes.
See Appendixes for more information about the RJ-45 port connectors.
Note:
Use only Category 5 copper unshielded twisted pair (UTP) cable
connections when connecting 10BASE-T/100BASE-TX ports.
