a. Touch the static-protective package that contains the hard disk drive to any
unpainted surface on the outside of the enclosure; then, remove the hard
disk drive from the package.
b. Make sure that the tray handle is open; then, slide the hard disk drive into
the hot-swap bay.
c. Push the tray handle to the right into the closed (latched) position.
a. When a drive is ready for use, the green activity LED and the amber status
LED on the drive are off.
b. If the amber status LED is lit and not flashing, remove the drive from the
unit and wait 10 seconds; then, reinstall the drive. If the amber LED is
flashing, the drive is rebuilding.
Controller management information: In some cases, the RAID controller automatically
resets the drive to the Hot Spare or Rebuild state. If the drive state does not change
automatically (the amber LED stays lit), see your RAID controller management
documentation for information about manually changing the state of the drive from the
current state to another state, such as Hot Spare or Ready. The amber LED should turn off
within 10 seconds after the drive state changes.
