Using the BayStack 450 10/100/1000 Series Switch
2-14 302401-D Rev 00

Verifying the Installation

When power is applied to the switch, power-on self-tests run. You can verify

proper operation of the BayStack 450 switch by observing the front-panel LEDs

or by viewing the self-test results as displayed in the BayStack 450 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. Observing LEDs to Verify Proper Operation
Table 2-1. Power-Up Sequence
Stage Description LED indication
1 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
Pow er LED d oes n ot turn on, ve rify tha t power is avail able at the
A C po w er o utlet and that the po w er cab l e is fastened s ecurely a t
both ends . If the P o wer LED remai ns off , contact the sales agent
or the customer service representative from whom you
purchased the switch.
2 The switch initiates a self-test. As subroutines are initiated by the self-test, the port statu s 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.
