2.2 Preparing the Expander Box
Caution
To prevent damage to equipment, take the following precautions:
• Only qualified service personnel should remove the cover or install
drives.
• Static electricity can damage integrated circuits. Always use a
grounded wrist strap and a grounded work surface (29–26246)
when working with the internal parts of a computer system.
• Shut down the operating system in an orderly fashion before you
remove or install drives; the procedures in this document assume
that the operating system has been shut down first.
• Turn off the system power before you remove or install drives (see
Section 2.2.1).
Prepare the expander box for the addition of a drive:
1. Turn off all power (Section 2.2.1).
2. Remove the cover (Section 2.2.2).
2.2.1 Turn Power Off
Turn off power first to all expander boxes, then to the system unit, and remove
the power cord from the expander box to be upgraded.
2.2.2 Remove the Cover from the Expander Box
Loosen the two cover release screws on the back of the expander. Grasp each
side of the cover and pull it toward you (see Figure 2–1). Then pull the cover
up and away from the box.
