How to thread the electrical cable through the dividers. Step 2. Note the point where the power wire meets the rear hole in the divider. Measure back 6" toward the power brick and fold the wire in half to create a loop in the center of the wire. This loop will be used in Step 3, page 11. Unplug the power wire from the netbook and remove the netbook from the divider. Figure 4-4. Loop the electrical cord and push it through the circular hole at the top rear of the divider. Page 10 724-746-5500 | blackbox.com NBC20S Chapter 4: Configuration and Setup Step 3. Insert the loop created in Step 2 through the rear small hole at the top of the divider (Figure 4-4). Then, place the plug end of the wire through the loop (Figure 4-5). Make sure that the loop is on the side of the divider (not on top of it—see Figure 4-6). This will ensure that the divider will slide back into the cart. Then, tighten the loop down to the divider, tightening the knot. Figure 4-5. Insert the plug end of the wire through the loop. Keep the loop here Power brick end Figure 4-6. Make sure the loop is on the side of the divider, not on top of it. Step 4. Run the wire along the top of the divider and repeat the process of creating a loop in the power cord. Place this loop through the small hole at the front of the divider (Figure 4-7). Now place the plug end of the wire through the loop (Figure 4-8). Pull the end of the cable, tightening the loop (Figure 4-9). Figure 4-7. Create a loop from the power cable and feed it through the hole at the top front of the divider. NBC20S 724-746-5500 | blackbox.com Page 11 Chapter 4: Configuration and Setup Figure 4-8. Insert the plug end of the wire through the loop. Keep the loop on top Figure 4-9. Pull the cable taught to secure the loop. Step 5. Wrap the remaining length of power cord around the power brick (see Figure 4-11, page 13. Step 6. Wrap the plug wire around the brick. Leave at least 7" of extra cable if the divider will be inserted into the bottom shelf, or at least 21" of extra cable if the divider will be inserted into the top shelf. Lower shelf: 7" Upper shelf: 21" Figure 4-10. Wrap the remaining electrical cable around the power brick. Leave 7" of extra cable if the divider will be inserted into the bottom shelf, or at least 21" of extra cable if the divider will be inserted into the top shelf.

Strap Figure 4-11. Strap the brick and cord in place using a zip tie or hook-and-loop tie (not included). Step 8. Install the assembled divider into the cart using the following steps. Figure 4-12. A divider with a power brick properly attached. NBC20S 724-746-5500 | blackbox.com Page 13 Chapter 4: Configuration and Setup NOTE: For proper installation, make certain that all power bricks are installed on the same side of every divider. 4.3 Inserting Dividers Into the Cart Step 1. Beginning with the top row, insert a divider into the cart. Figure 4-13. Begin to insert dividers into the top row of the cart. Step 2. Then from the back of the cart, insert the power brick plugs hanging from the dividers on the left side of the cart into the power receptacles located on the bottom left of the cart. Repeat with the power brick plugs on the right side of the cart into the power receptacles located on the bottom right of the cart. Figure 4-14. Netbook Cart dividers with attached power bricks. Step 3. Plug the power cord from the bottom left receptacles into one of the timer’s receptacles and the power cord from the bottom right receptacles into the timer’s other receptacle.

In the back of the NBC, insert the power cord from the 10 or 16 electrical outlet unit into the LEFT outlet on the timer and plug the other electrical outlet unit into the RIGHT outlet on the timer. Push the timer tabs (located at the edges of the timer dial) inward towards the center of the dial. This will turn one side of the outlets on while turning the other off. 4.4 Routing the Power Cords at the Back of the Netbook Cart Step 1. Plug the netbook outlet strips into the timer unit Step 2. Feed the cord from the timer through the grommet hole on the side nearest the handle and wrap the cord around the handle itself or around the cord wrap below the handle. Step 3. Plug the timer into a wall outlet. NOTE: The outlet strips are only to be used for chargin...
