Step 4 Turn off the DC power source that is providing power for each DC PEM. All LEDs on the DC PEM
should turn off.
Tip Separate DC power sources should be used for each DC PEM. This allows you to turn off the power
source for one DC PEM without affecting the power source for the online DC PEM.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.
To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC
circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit
breaker in the OFF position. Statement 7
Step 5 Loosen the captive screws on each DC PEM and pull each DC PEM from the chassis using the handle
on the faceplate (see
Figure 5-12). Set the two DC PEMs aside.
