Switch LEDs
Meaning
The switch is receiving power.
The switch is NOT receiving power.
The normal state; indicates that there are no fault conditions on the switch.
A fault has occurred on the switch, the switch module (if installed), or a fan. The Status
LED for the device 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 3, "Troubleshooting" for more information.
The normal operational state; the switch is not undergoing self test.
The switch self test and initialization are in progress after you have power cycled or
reset the switch. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you "hot swap" a module into the switch; the module 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 a fan, and the switch Fault LED will blink simultaneously.
Indicates that the port Mode LEDs are displaying network activity information.
Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode.
Indicates that the port Mode LEDs are lit for ports that are operating at 100 Mbps.
A module is installed in the switch module slot and that the module is undergoing or
has passed self test.
A module is not installed in the switch module slot.
The module in the slot has failed self test or is not installed properly. The switch Fault
LED, and the Self Test LED may be flashing simultaneously. If the Module Status LED is
flashing by itself, a different module type has been hot swapped into the slot without
the switch being reset. See "Hot Swapping Switch Modules" on page 2-20.
The cooling fans are operating normally.
One or more of the cooling fans have failed. The switch Fault LED will be flashing
simultaneously.
