2. Push in the locking latch of the desired hard drive slot and then pull the ejector handle
toward you.
3. Pull the ejector handle to slide the hard drive carrier out of the slot.
4. Assemble the hard drive and the carrier. The carrier consists of a rail, a PCA cover, and
two support bars. The two support bars should be removed before installing the hard
drive. Refer to Figure 2-9.
a. Remove the two support bars by removing two screws on each side of the carrier.
b. Place the drive inside the carrier.
c. Replace two screws to each side of the carrier.

5. Slide the drive into the slot until you feel resistance, and then press firmly until the drive
is fully seated into the connector on the back plane.
6. Verify the hooks behind the pivot end of the handle engage the hole in the edge of the
cage.
7. Press the ejector handle in until you feel the latch click into place.
Closing the ejector handle engages the drive with the electrical connector in the hot swap
drive cage and seats the drive.
8. If the drive is unseated in the cage after closing the ejector handle, remove the drive and
insert it once again.
The handle was probably not pulled out far enough, and the locking latch failed to engage
the hot swap mass storage cage.
