Figure 18. Plugging an ethernet cable into a 10/100BASE-TX port
To attach segment cables to your 10/100BASE-TX ports:
1.
For all the 10/100-Mbps ports, obtain copper cables that have the following pin assignments.
The RJ-45 connectors on the 10/100 ports are configured as Media Data Interface Crossed
(MDIX). You can use Category 3 (Cat-3) or higher wire for 10-Mbps segments. For 100-Mbps
segments, use Cat-5 or higher wire. The ports automatically sense to which type of segment
they are connected and configure themselves to transmit and receive at the appropriate
bandwidth.

The right hand column pin assignments are for the RJ-45 connector on the XP-2000. Thus, pin 1 (TXD or
“transmit data”) must emerge on the management console’s end of the connection as RXD (“receive data”) and
so on.
