Installing an Internal Disk Drive CRU
Follow these instructions to install an internal disk drive customer-replaceable unit
(CRU).
1 Follow standard operating practices when handling the disk drive CRU.
2 Unlock and open the appearance-side enclosure door, if necessary.
Caution: Minimize the time the enclosure door is open to avoid
overheating other components in the enclosure. Refer to Safe Operating
Times With Enclosure Door Open.
3 Attach the grounding clip of the ESD wriststrap to any unpainted metal on
the enclosure frame, such as the door latch stud.
4 Check for any damaged pins on the square 24-pin power connector located
on the rear of the disk drive CRU. Do not attempt to install a disk drive CRU
that has damaged pins. For more information, see NTL Support and Service
