Verifying the Installation

When power is applied to the switch, power-on self-tests are run. You can verify
proper operation of the BayStack 410-24T switch by observing the front-panel
LEDs or by viewing the self-test results as displayed in the BayStack 410-24T
switch Self-Test screen.

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

Figure 2-10.

Description

LED indication

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

The Power LED turns on within 5 seconds (

Figure 2-10

). If the

Power LED does not turn on, verify that power is available at the
AC power outlet and that the power cable is fastened securely at
both ends. If the Power LED remains off, contact the sales agent
or the customer service representative from whom you
purchased the switch.

The switch initiates a self-test.

As subroutines are initiated by the self-test, the port status LEDs
flash various patterns. When the switch passes the self-test
(within 10 seconds), the Status LED turns on (

Figure 2-10

If a nonfatal error occurs during self-test, the Status LED blinks.

If the switch fails the self-test, the Status LED remains off.
Contact the sales agent or the customer service representative
from whom you purchased the switch.
