When the unit is in a standard operating state, the LEDs behave in a defined
manner. The standard operating states are defined in Table 4.3.
An 8400 platform that shows no light on the Activity LED during regular
operations is functioning normally. For information about a green solid
Activity LED on an 8400 platform, see Green solid Activity indicator LED,
on page 4-4.
