Installing the Cisco NCS 4216
DETAILED STEPS
Step 1
Ensure that the system (earth) ground connection has been made. For ground connection installation instructions, see
the Installing the Chassis Ground Connection section.
Step 2
If necessary, remove the blank power supply filler plate from the chassis power supply bay opening by loosening the
captive installation screws.
Step 3
Verify that power to the DC circuit connected to the power supply you are installing is off. To ensure that power has
been removed from the DC circuits, locate the circuit breakers for the DC circuits, switch the circuit breakers to the OFF
position, and tape the circuit-breaker switches in the OFF position.
Step 4
Grasp the power supply handle with one hand. Place your other hand underneath the power supply, as shown in the
figure below. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the
bay.

Step 5
Tighten the captive installation screws of the power supply. The recommended maximum torque is 5.5 in.-lb (.62 N-m).
If you are installing a redundant DC power supply, repeat these steps for the second power source.
