WARNING!
Never disconnect a Wireless AP from its power supply during a firmware upgrade. Disconnecting a Wireless AP from
its power supply during a firmware upgrade may cause firmware corruption rendering the AP unusable.
The table below assumes the software uses a timer and multiple phases to simulate LED blinking on all
three LEDs. For example, an LED status of Red indicates the LED is solid colored Red, an LED status of
Off/Green/Off indicates that the LED is Off for the first phase, Green for the second phase, and Off for
the third phase.
NOTE
Random delays do not occur during normal reboot. A random delay only occurs after vulnerable period power-down.
The Wireless AP can be reset to its factory default settings. For more information, see “Resetting the AP to Its
Factory Default Settings” on page 199.
