• Segment LEDs — flash yellow, then change to the color
indicating the position of the Segment switch.
• Port Status LEDs:
• 10BASE-T and Dual ST LEDs flash yellow and then
go off. Once testing is complete, these LEDs indicate
port activity.
• AUI and BNC LEDs turn green after the power-on
sequence and remain on until a data packet has been
passed successfully. If the BNC port is not termi-
nated, the BNC LED will light yellow and the port
will partition due to excessive collisions.
• Collision LEDs — turn yellow for a fraction of a sec-
ond, then go off. Once testing is complete these LEDs
indicate network activity.
Refer to Chapter 5, “Troubleshooting,” for more information
about the LEDs.
