2 System Information
Introduction
This chapter provides information on mass storage, connector pin-outs, accessory guidelines and system
specifications.
Mass Storage
The HP Netserver LP 2000r 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 6 total SCSI drives.
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.
◊ Do not stack drives.
◊ The Netserver may have up to 6 Hot Swap SCSI hard disk drives (HDD). A flexible disk
drive and CD-ROM drive are standard on all models of the HP Netserver LP 2000r.
◊ If a backup tape drive is used, it should be connected externally using the external 68-pin
SCSI connector at the rear of the Netserver.
• 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. (Only IDE-1 is used.)
◊ The IDE CD-ROM has only one connector on the cable from the primary channel (IDE-1)
connector.
◊ A secondary IDE connector (IDE-2) is available on the system board, but is not used.
• SCSI Device Selection
◊ Use only HP LVD low profile (1 inch) SCSI 3.5-inch hard disk drives in the Hot Swap drive
slots.
◊ Ensure the SCSI devices you install in Hot Swap slots do not have terminations installed.
The Hot Swap backplane provides automatic termination for any unused slots. The HP Hot
Swap SCSI drives come set without device ID or termination. Do not change these settings.
◊ Do not use high voltage differential (HVD) SCSI devices on either of the SCSI channels.
Using these devices will damage the backplane and render the SCSI drive slots inoperable.
◊ The embedded dual-channel Ultra-160M SCSI controller includes connectors for SCSI
channels A and B.
◊ Channel A is used for connecting to the two SCSI backplane boards. The standard SCSI
cable has one 68-pin, high-density connector for connecting to SCSI backplanes.
