(Optional) Installing power trays
The device comes with four power trays installed. You can install more power trays on it.
To install a power tray:
1. As shown in Figure 3-21 and Figure 3-22 , remove the front and rear filler panels from the
target power tray slot.
2. As shown by callout 1 in Figure 3-23 , hold both sides of the power tray with two hands, and
insert the power tray into the slot along the guide rails slowly and steadily.
3. As shown by callout 2 in Figure 3-23 , close the ejector levers when the ejector levers touch the
slot edges tightly.
4. As shown by callout 3 in Figure 3-23 , use a screwdriver to fasten the screws on the power tray.
As a best practice, use a torque of 5 kgf-cm (0.49 Nm) to fasten the screws.
