First you need to get a key-card from Object #21WS.

First of all, we go to the substation and turn on the lewer.

Find the lewer on the Interchange map.

Next we go to the warehouse in the direction of the transit to the Customs, we are interested in a closed container in the center. We open it with a card, take a case (see below on the floor or on the shelf).
