Lower Bay Trays

Overview

Lower bay trays can be mounted in one of six (6) locations for short trays and one of three (3) locations for long trays. This flexibility is useful when planning ahead (e.g., a buck converter can be located near the device it powers for shorter wiring).

Long Trays

Long trays can be mounted in the front, middle, or back of the lower bay. They can only be mounted with the long side oriented sideways.

Directions

1. Snap the Wago connectors in place. We leave half of the tray unoccupied for future expansion.

2. Determine the best location for the tray. Here, it is set in the center to shorten wiring.

3. Secure with four (4) M4 x 6mm screws.

Short Trays

Short trays can be mounted in any one of six (6) locations in the lower bay. Short trays do not always fit next to an occupied CPU bay.

Directions

1. Set the buck converter on the tray's standoffs and secure with four (4) M4 x 6mm screws. It is a good idea to ensure the converter's voltage level is set at this point.

2. Determine the best location for the tray in the lower bay. In this case, the tray will not fit next to the Raspberry Pi, so it is placed in the back.

3. Secure the tray to the case with four (4) M4 x 6mm screws.
