Terminator LED
The Terminator LED, located on the rear panel of the hub, indicates that the built-in terminator in that
hub is active. When two or more hubs are cascaded together in a stack, the Terminator LED on the
top-most hub and the LED on the bottom-most hub should be lit to indicate that the terminator is
active in those hubs. The Terminator LED on the center hubs should not be lit. Use Table 2-2 to
determine which hubs in a stack should have the terminator active (LED on).
