Verifying the Installation Using the LEDs

To verify the installation using the LEDs, check that the switch power-up sequence is as described in Table 2-1:

Table 2-1. Power-Up Sequence

Stage Description LED indication

1Immediately after AC power is applied to the switch, DC power is available to the switch’s internal circuitry.
