Typically, modules, power supplies, and fan trays are packaged in cartons. The packaging materials 
include cartons, foam cushions, and anti-static bags. 

To unpack and inspect a component: 

1. 

Use a utility knife to cut the straps on the carton. Open the carton and take the top foam cushion 
out of the carton. 

2. 

Wear an ESD wrist strap and make sure the wrist strap is reliably grounded. 

3. 

Take the component out of the anti-static bag. 

4. 

Check the items in the carton against the packing list to verify that the items are as ordered.
