Attaching the Cables and Supplying Power

After you install the Alpine 3802, you must attach the cables that supply power to the chassis. To attach
the cable to the lugs, and then to the DC power supply, perform the following steps:
1 Attach the ESD strap to your wrist and connect the metal end of the ESD strap to the ground
receptacle on the top right corner of the switch front panel.
2 Remove the plexiglas cover that shields the power connection on the power supply.
3 Strip 0.5 inches of insulation from the AWG, high strand-count copper cable.
4 Insert the cable into the DC ground and power cable lugs on the power supply.
CAUTION
Make sure that no copper is visible between the lug and the cable insulation.
5 Using a # 2 phillips screwdriver, tighten the cable retention screw, to a maximum of 10 inch-pounds
(1.2 Nm) of torque.
6 Replace the plexiglas cover.
7 Turn on the DC supply at the wall breaker.
8 Turn on the power supply breaker.
Leave the ESD strap permanently connected to the chassis so that it is always available when you need
to handle ESD-sensitive components.

Verifying Successful Power Installation

This sections describes how to verify successful power installation for any Alpine 3800 series switch.
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.
