1)  Wear an ESD-preventive wrist strap and loosen the captive screws on the power module (see 

callout ① in 

2)  Grasp the handle of the power module with one hand to pull out a part of it. Then hold the module 

bottom with the other hand and take out the module slowly (see callout 

 in

Since the power module of the S7900E series is heavy, you are recommended to grasp the handle of 

the power module with one hand and hold the bottom with the other while pulling out a power module 

slowly. 

If you are not going to install a new power module after removing a power module, you should install a 

blank panel for the heat dissipation and dust-proof purpose. 

 

Install a power module in the opposite order you remove it: 

1)  Put on an ESD-preventive wrist strap and take a new power module out of its package. Check that 

the input mode of the power module is as required.
