need to handle ESD-sensitive components.

Verifying a Successful Installation

After you supply power to the Alpine switch, the switch performs a power-on self test (POST).
During the POST:
• All ports are temporarily disabled
• The packet LED is off
• The power LED is on
• The MGMT LED flashes until the switch successfully passes the POST.
If the switch passes the POST, the MGMT LED blinks at a slow rate (one blink per second). If the switch
fails the POST, the MGMT LED shows a solid yellow light.
NOTE
See Chapter 9, "Alpine 3800 Series Switch Management Module" for more information about switch
management module LED activity and Chapter 10, "Alpine 3800 Series I/O Modules" for more
information about I/O module LED activity.
