3. 

Connect the other end of the AC power cord to the AC power 
source, and turn on the circuit breaker. 

4. 

Examine the AC OK LED on the power module. If the LED is 
steady green, the power cord is connected correctly. If the LED 
is off, examine the installation, troubleshoot the problems, and 
try again until the LED is steady green. 

Removing the power module 

To avoid bodily injury or device damage, follow the procedure

Figure 6 Removing procedure 

 

 

To remove the power module: 

1. 

Turn off the circuit breaker at the power input end. 

2. 

Put on the ESD wrist strap and make sure the strap makes good

As shown in 

Figure 7

, press the latch towards the handle, and 

pull the power module part way out of the slot along the guide 
rails.

Holding the power module handle with one hand and supporting 
the power module bottom with the other, pull the power module 
slowly out of the slot along the guide rails. 

6. 

Put the removed power module on an antistatic mat or into its 
package. 

7. 

If you are not to insert a power module into the empty slot, insert 
the filler panel into the slot to prevent dust from entering the 
chassis.
