Prior to adding Drive Enclosures, install rails into the rack for each Drive Enclosure that you plan to add.
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
If you are installing the rails in a rack with threaded holes, make sure you have a Torx Number 20 screwdriver.
