2 System Information
Introduction
This chapter provides information on mass storage, connector pin-outs, accessory guidelines and system
specifications.
Mass Storage
The HP NetServer E 800 comes standard with an IDE CD-ROM and a flexible disk drive with some
configuration of SCSI hard disk drives. The internal mass storage cage can hold up to 5 additional SCSI
drives (including a tape back up drive).
Mass Storage Guidelines
•
General Guidelines
◊
Use care when unpacking and handling the SCSI disk drives.
The hard disk drives are very susceptible to mechanical shock and can be easily damaged
by a drop as short as one-quarter of an inch. If the drop would crack an egg, it will damage
the drive.
◊
Do not stack drives.
◊
The NetServer is internally limited to 7 mass storage shelves.
The flexible disk drive and CD-ROM drive, which are standard on all models of the HP
NetServer E 800, occupy shelves 1 and 2 respectively.
◊
If a backup tape drive is used it will occupy shelf 3.
◊
Shelves 4, 5, 6, and 7 are available for SCSI hard drives and one is required for the boot
drive.
•
IDE Devices
◊
The embedded IDE controller is an Enhanced-IDE dual channel controller and provides two
connectors (IDE-1 and IDE-2) for IDE devices.
◊
The IDE CD-ROM uses only one connector on the cable from the primary channel (IDE-1)
connector.
◊
A secondary IDE connector (IDE-2) is available, but is not supported by Hewlett-Packard.
•
SCSI Device Selection
◊
Use only low-voltage differential (LVD) SCSI devices.
◊
Do not use high voltage differential (HVD) SCSI devices on either of the SCSI channels or
damage will occur.
◊
Ensure the SCSI devices you install do not have terminations. The SCSI drives are
connected to a terminated cable and don't require termination on the SCSI drive.
◊
Use only HP LVD SCSI 1-inch low-profile 3.5-inch hard disk drives for the removable hard
disk drive cage.
