Removing the Chassis

Grounding the Alpine 3800 Series Chassis

To ground your Alpine 3800 series chassis in accordance with NEBS standards, gather

these materials:

• Two zinc-plated steel lockwashers

• Two zinc-plated steel nuts

• One Panduit-style, standard two-hole barrel, copper compression lug

• Four AWG, high strand-count wire copper cable

To ground the chassis:

1 Strip 0.5 inch (1.2 cm) of insulation from the four AWG, high strand-count cable.

2 Insert the cable into the cable lug.

Caution: Ensure that no copper is visible between the lug and the cable

insulation.

3 Tighten the cable retention screw, using a

”

flathead screwdriver, to 20

in-lbs of torque.

4 Attach the ground lug, lock washers, and nuts (in that order) to the grounding studs

on the rear of the chassis. Tighten the nuts to 125 in-lbs of torque.

Removing the Chassis

This section describes how to remove the Alpine 3800 series chassis from the rack.

To remove the Alpine 3800 series chassis from a standard 19-inch (48.26-cm) rack:

1 Unplug the power cord from the outlet and then from the switch before you attempt

to remove the chassis components and the chassis from the rack.

2 Mount the helper bracket in the rack directly beneath the chassis using four screws

that are appropriate for your rack.

3 To reduce weight and prevent possible equipment damage:

• Remove the power supply, the SMMi, and the I/O modules from the Alpine 3808

and Alpine 3804.

• Remove the I/O modules from the Alpine 3802.
