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).

Overview

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 side-to-side.

As an example of a Long tray, we'll install a buck converter for the Raspberry Pi and a pair of 5 position Wago connectors.

Directions

1) Snap the two (2) Wago connectors in place.

2) Attach the buck converter to the tray with two (2) M3 x 6mm screws.

3) Position the tray in the case. Large trays are often installed in the middle of the case, out of the way of side panels or CPU trays.

4) Secure the tray in place with four (4) M3 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.

In the example below, we'll install another buck converter on a short tray.

Directions

1) Set the buck converter on the tray's standoffs and secure with two (2) M3 x 6mm screws. It is a good idea to ensure the converter's voltage level is set at this point.

2) Position 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) M3 x 6mm screws.
