11.Grasp the handle on the power supply faceplate and pull firmly. Slide it halfway out of the chassis (see Figure 12 on page 21).

CAUTION: Each two-input 160-A power supply weighs approximately 23 lb (10.5 kg). Be prepared to support the full weight of the power supply as you remove it from the routing platform.

12.Place one hand underneath the power supply to support it and slide it completely out of the chassis.

CAUTION: Do not leave a power supply slot empty for more than a short time while the routing node is operational. For proper airflow, the power supply must remain in the chassis or a blank panel must be used in an empty slot.
