Normal Power-Up Sequence

In a normal power-up sequence, the LEDs appear as follows:

1.After power is applied to the switch, the Pwr (Power) LED turns on within 5 seconds.

2.The switch initiates a self-test, during which the port LEDs display various patterns to indicate the progress of the self-test.

3.Upon successful completion of the self-test (within 10 seconds after power is applied), the Status LED turns on.

4.The remaining port LEDs indicate their operational status, as described in Table 4-2.
