Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 59)

NOTE: You should only use drives that have been tested and approved by the system manufacturer for use with the
SCSI backplane board.
You may need to use different programs than those provided with the operating system to partition and format hard drives.
See "Installing and Configuring SCSI Drivers" in the User's Guide for information and instructions.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.
When you format a high-capacity hard drive, allow enough time for the formatting to be completed. Long format times for
these drives are normal. For example, an exceptionally large drive can take over an hour to format.
SCSI Backplane Board Configuration
The hard-drive bays provide space for up to five 1-inch SCSI hard drives. The hard drives connect to a controller on the
system board or a RAID controller card through the SCSI backplane board.
The system provides several options for hard drive configurations:
SCSI backplane daughter card (see " Installing the SCSI Backplane Daughter Card "):
1 x 5 configuration, without the SCSI backplane daughter card installed
2 x 3 split configuration, with the SCSI backplane daughter card installed
SCSI controller:
Integrated SCSI controller
Integrated RAID controller (see " Activating the Integrated RAID Controller ")
RAID controller card (see " Installing a RAID Controller Card ")
An integrated RAID controller card is installed by default; no cables are required to use the integrated RAID controller
in either a 1 x 5 or 2 x 3 split configuration.
See Figure 5-5 to locate the connectors on the SCSI backplane board.
Removing a Hard Drive
1. Remove the bezel (see " Removing the Bezel ").
2. Take the hard drive offline and wait until the hard-drive indicator codes on the drive carrier signal that the drive may
be removed safely (see Table 3-6 ).
If the drive has been online, the drive status indicator will blink green twice per second as the drive is powered down.
When all indicators are off, the drive is ready for removal.
See your operating system documentation for more information on taking the hard drive offline.
3. Open the hard-drive carrier handle to release the drive (see Figure 4-18 ).
4. Slide the hard drive out until it is free of the drive bay (see Figure 4-18 ).
If you are permanently removing the hard drive, install a blank insert.
