When the switch is powered on, it performs its diagnostic self test and
initialization. This boot process takes approximately 50 seconds to
complete.
LED Behavior:
During the switch boot:
•The Power, Fault, Test, and Locator LEDs, other Status LEDs, Mode
indicator LEDs, and port LEDs are on for most of the duration of the
test.
• Most of the LEDs go off and may turn on again during phases of the
boot.
When the switch boots successfully, Status LEDs display:
• Power and Tmp LEDs (and the PoE LED for PoE+ switches) remain on.
• Fault, Test, and Locator LEDs are off.
• Other status LEDs may be on or off depending on the switch
configuration and the hardware installed.
