Observing The Power Status Leds - Extreme Networks ExtremeSwitching CES 2000 Series Hardware Installation Manual

Operation verification
4. Verify proper operation by observing the LEDs.
All the port LEDs should flash momentarily, usually in sequence, while the device performs diagnostics. After the diagnostics
are complete, the LEDs will be dark except for the ones that are attached by cables to other devices. If the links on these cables
are good and the connected device is powered on, the link LEDs will light.
