SM5000, front view showing the four hard disk drive bays
Hardware Configuration
On the SM5000 and WS5000, the disks are mirrored using RAID 10, so only one disk can be
replaced or not be working at a time.
Failure Identification
Remove the front bezel to expose the disk drives. On a failed disk drive, the red LED on the front
of the drive is illuminated (the bottom LED of the two drive-specific LEDs) and the appliance’s
audible alarm is sounding.
Static-Sensitive Devices
CAUTION:
Electrostatic discharge (ESD) can damage electronic components.To prevent damage to any
printed circuit boards, it is important to handle them very carefully. The following measures are
generally sufficient to protect your equipment from ESD damage.
■
Be sure that the appliance chassis is properly grounded through the AC power cord or enclosure
frame.
■
Touch a grounded metal object before removing the drive from the antistatic bag.
■
Put on the grounding wrist strap, handle the drive by its edges only, and do not touch
components on the bottom.
Single Hard Drive Replacement Procedure
As the disks are mirrored using RAID 10, only one disk can be replaced or not be working at a
time.
CAUTION: Disk drives are static-sensitive devices. Please make proper use of the wrist strap
included in the disk field-replaceable unit (FRU) ship kit.
CAUTION: Removal of the other drive during this procedure or during the rebuild of the RAID
10 mirror will result in system failure.
