Standalone Switch and Port LED Behavior
Meaning
The switch is receiving power.
The switch is NOT receiving power.
The normal state; indicates there are no fault conditions on the switch.
A fault has occurred on the switch, one of the switch ports, a module in the rear of the
switch, or the fan. The Status LED for the component with the fault will blink
simultaneously.
On briefly after the switch is powered on or reset, at the beginning of switch self test.
If this LED is on for a prolonged time, the switch has encountered a fatal hardware
failure, or has failed its self test. See chapter 4, "Troubleshooting" for more information.
The Locator LED is used to help you identify a specific in your network equipment
installation. The LED can be set to be on solid or to blink, and for a specified number of
minutes (1-1440). The default is 30 minutes. Use the command "chassislocate" to
control this LED.
The normal operational state; the switch is not undergoing self test.
The switch self test and initialization are in progress after the switch has been power
cycled or reset. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you "hot swap" a mini-GBIC into the switch; the mini-GBIC
is self tested when it is hot swapped.
A component of the switch has failed its self test. The status LED for that component,
for example the Fan LED, and the switch Fault LED will blink simultaneously.
For non-PoE or PoE-disabled ports:
Displays port link information:
• On – The port is enabled and receiving a link indication from the connected device.
• Off – The port has no active network cable connected, or is not receiving link beat
or sufficient light (fiber-optic port). Otherwise, the port may have been disabled
through the switch console, the web browser interface, or network management.
• Blinking orange* – The corresponding port has failed its self test. Blinks simultane-
ously with the switch Fault LED.
For PoE-enabled ports, see the LED mode information for PoE mode below.
The operation of the port Mode LED is controlled by the LED Mode select button, and
the current setting is indicated by the LED Mode indicator LEDs near the button. Press
the button to step from one view mode to the next. The default view is Activity (Act).
If the Save Power LED feature has been enabled on the switch (savepower led
command), then that becomes the default view - all port LEDs are Off when the switch
is operating according to that feature.
