6 Replace the plexiglas cover.
7 Turn on the DC supply at both the wall breaker and at the power supply breaker.
8 Leave the ESD strap permanently connected to the chassis so that it is always available when you
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, and
the MGMT LED flashes. 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.
