For more information on cable and connector pinouts, refer to Appendix B,
PathBuilder S21x Switch Cabling or to the Daughtercard Installation Guide for
information on the optional daughtercards.
Control Terminal
Port Cable
Use an RJ45 (male) to DB25 (female) cable that comes with the PathBuilder S21x
switch to connect to the Control Terminal Port (CTP). The PathBuilder S21x switch
defaults this port to 9.6 kbps, 8 bits, no parity, 1 stop bit.
Note
If you plan to use a personal computer to configure the PathBuilder S21x switch,
you may need to purchase a DB25 (male) to DB9 (female) adapter for the serial
port of your personal computer. The serial ports on most personal computers
require DB9 connectors.
10BaseT Ethernet
Cable
Follow these guidelines for 10BaseT cable connections:
• If you are connecting to a 10BaseT Hub, use a standard UTP cable
(RJ45 to RJ45).
• If you are connecting directly to a personal computer or Workstation LAN
card, use the 10BaseT crossover cable shipped with your PathBuilder S21x
switch.
