Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 67)

This subsection describes how to configure and install an external SCSI tape drive.
Installing an External SCSI Tape Drive
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System
Information document.
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Prepare the tape drive for installation.
Ground yourself by touching an unpainted metal surface on the back of the system, unpack the drive (and controller
card, if applicable), and compare the jumper and switch settings with those in the drive documentation.
See " SCSI Configuration Information ," for information on setting the drive's SCSI ID number and enabling termination
(if required). Change any settings necessary for your system's configuration.
3. Connect the tape drive's interface cable to the external SCSI connector on the controller card.
4. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
5. Perform a tape backup and verification test with the drive as instructed in the software documentation that came with
the drive.
SCSI Hard Drives
This subsection describes how to install and configure SCSI hard drives in the system's internal hard-drive bays.
Before You Begin
Before attempting to remove or install a drive while the system is running, see the documentation for the RAID controller
card ensure that the system is configured correctly to support hot-pluggable drive removal and insertion.
SCSI hard drives are supplied in special drive carriers that fit in the hard-drive bays.
NOTE: You should only use drives that have been tested and approved 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 SCSI 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 SCSI 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 a SCSI Backplane Daughter Card "):
1x5 configuration, without the SCSI backplane daughter card installed
2x3 split configuration, with the SCSI backplane daughter card installed
