Screen and Control Keys on page 1-2). Use the buttons next to the display to navigate the display

Removing and Installing a Disk Drive
The FS7500 controller supports up to six 2.5 inch SAS disk drives. This section discusses how to
handle and store disk drives, as well as how to install and remove the drives and drive blanks.
Disk Drive Handling Requirements
Observe the following considerations when installing hard drives:
• Install all disk drives from the front of the system. The drives connect to the system board
through the SAS backplane board. Disk drives are supplied in special hot-swappable drive
carriers that fit into the disk drive bays.
• Protect disk drives from electrostatic discharge. When handling a disk drive, always wear an
electrostatic wrist strap or similar protective device. See Using an Electrostatic Wrist Strap on
page 2-2.
• Handle disk drives carefully. Hold a disk drive only by the plastic part of the carrier. Do not
handle a disk drive solely by the release lever.
• Insert a disk drive properly. Do not force a disk drive into a slot.
