Dell PowerVault 770N (Deskside NAS Appliance) - Manual (Page 51)

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 six 1-inch hard drives, and the peripheral bay provides space for two more
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 the following options for hard drive configurations:
1 x 6 configuration
1 x 6 + 1 x 2 split configuration, with two hard drives installed in the peripheral bay (see " Replacing the Peripheral
Bay ")
RAID controller:
Integrated RAID controller (see " Integrated RAID Controller ")
RAID controller card (see " Installing a RAID Controller Card ")
Cabling:
Additional cables are not required to use either the onboard SCSI controller or integrated RAID controller in a 1 x
6 configuration.
If a RAID controller card is installed, cables can be connected from the controller card to SCSI A and/or SCSI B
backplane board connector(s). A backplane board connector that is not attached to the RAID controller card will
use the onboard SCSI controller or integrated RAID controller.
See Figure 5-4 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 two times a 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 4-20 ).
4. Slide the hard drive out until it is free of the drive bay (see Figure 4-20 ).
If you are permanently removing the hard drive, install a blank insert.
5. Replace the bezel (see " Replacing the Bezel ").
