Use a null-modem serial cable when connecting to aworkstation (see “Appendix C. Cable Pinout Diagrams” on page 79). Use aVT100 terminal emulator program to configure your terminal’s attachedCOM port as follows:v 19 200 baudv 8 data bitsv 1 stop bitv No parityv Hardware flow control OFFSee “Chapter 2. Accessing the 8275-416” on page 11 for more informationabout connectivity.Ethernet 10/100BASE-TX PortsThe 8275-416 has 16 Ethernet 10/100BASE-TX ports. Each port has twoLEDs located at the lower right and left of the connector. Status indicationsof the Port LEDs are explained later in this chapter.Feature Module Slots 1 and 2These feature modules are available to expand port connections to your8275-416 :Figure 1.
