Hot-Swapping A Hard Drive - NEC HX4500 User Manual

Hot-Swapping a Hard Drive

If you are swapping out a faulty hard drive, you can pinpoint which drive to remove by
checking the status LEDs that occur in sets of three above each of the four drive bays.
See "Status LED Indicator Descriptions" in Chapter 1.
Note:
(steady yellow light), you can remove the drive and swap in a
replacement at any time when the drive is not being accessed,
without needing to power down the system. However, drive
manufacturers caution against moving a drive that is still spinning
because of possible damage to the drive.
1. If locked, unlock and open the right front door.
2. Determine which hard drive cage contains the faulty hard drive. Open the EMI
metal panel in front of the hard drive cage by turning its two thumb lock screws
counter clockwise (see Figure 4-25).
3. The hard drive cage has four hard drive slots. Check all the drive LEDs to confirm
which drive to remove. See "Status LED Indicator Descriptions" in Chapter 1.
Note:
spinning when you remove it. Follow the next step exactly when
removing drives.
4. Grasp the handle of the hard disk's carrier and press down on its thumb-release
button (see Figure 4-28). Pull the faulty drive out of the bay far enough to disengage
the drive connector from the backplane. Wait 30 seconds until the drive spins down,
then remove the drive from the drive bay.
Note:
5. Place the removed hard drive on an antistatic surface.
6. Remove the replacement drive from its protective wrapper and place it on an
antistatic surface. If a drive carrier was not shipped with the replacement drive,
remove the carrier from the removed drive.
7. Place the removed hard drive in an antistatic wrapper.
8. Position the replacement drive so its SCA connector is near the top surface of the
drive. Place drive on the antistatic surface again. Slide the drive into the carrier with
its SCA connector facing toward the front of the carrier (open end).
9. While holding the drive in the carrier with your left hand, align the drive's screw
holes with the carrier's screw holes and insert the four screws of appropriate size
and length (see Figure 4-26).
10. Pressing the lock button on the carrier handle, open the handle. Align the
drive/carrier assembly so it engages the guide rails in the hard drive cage (see
Figure 4-27).
