The system LED is amber on a Cisco Catalyst 2950 series switch. What does this indicate?

A.
The system is not powered up.

B.

C.

D.

E.

Explanation:
While the switch powers on, it begins POST, a series of tests. POST runs automatically to verify
that the switch functions properly. When the switch begins POST, the system LED is off. If POST
completes successfully, the LED turns green. If POST fails, the LED turns amber.
Note : POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
