The ACU is mounted in the main rack supplied with –48VDC power.

screws provided. For safe operation, follow these guidelines:
Do not mount the ACU in any orientation other than that specified in the
following illustration.
Mount the ACU so that both the front and the back are accessible.
If the mounting holes do not line up, adjust the ACU up or down until the
mounting holes line up.
Caution
Do not block the air vents on the sides or rear of the ACU.
3 Plug the ACU into main rack power source (rectifier or PDU).
4 Verify that the ACU is receiving power and that each NCU card is operational.
Each card installed in the front and back of the ACU has two LEDs: Power
and Status. All LEDs should light green.
