HP LH 6000 manual Accessory Board Guidelines, Hot Addition and Replacement of Hot Plug PCI Boards

Chapter 2 System Information

•Non-hot-swap, single-ended SCSI devices installed in the two empty trays adjacent to the CD- ROM drive

•Hot-swap Ultra-2 SCSI hard disk drives installed in the hot-swap mass storage cages

Use only high-performance, Ultra-2, hot-swap drives in the integral hot-swap mass storage cages.

You can add any Ultra/Wide, single-ended SCSI device in the non-hot-swap shelves, such as a removable hard disk or a tape backup drive. This table lists supported SCSI devices:

Location	Drive Type
Hot-swap Mass Storage	9.1, 18.2 or 36 GB, Ultra-2, 7200 or 10000 rpm drives (up to 35W)
Shelves
Non-Hot-Swap Shelves	9.1 or 18.2 GB Ultra/Wide or Single-Ended SCSI Drives, 7200 or 10000 rpm
	drives
	DAT backup systems with SCSI DDS3, or DLT Tape Drives

Accessory Board Guidelines

To install accessory boards, during initial installations, into the I/O board, perform the following procedures. The I/O board is under the top cover of the LH 6000r and under the left cover of the LH 6000.

lUse the respective NOS software utility to

◊Ensure the correct software drivers for the PCI board are loaded

◊Verify correct operation

◊Shut down power to hot plug slots

CAUTION Do not attempt to install or remove non-hot plug PCI boards with the HP NetServer in any kind of sleep state, or a system crash or hang may occur.

lSlots 1, 2, 3, and 4 are non-hot plug; slots 5, 6, 7, and 8 are hot plug.

lFor optimal performance, add PCI boards to slots 7 and 8, which at 66 MHz and 64 bit, are the fastest.

lConsider the boot priority prior to installing accessory boards, but after configuring the HP NetServer.

lSome accessory board outputs may exceed U.S. National Electrical code (NFPA 70) Class 2 or power source limits and must use appropriate interconnecting cabling in accordance with the National Electrical Code. (All Hewlett Packard boards comply with Class 2.)

lYou can configure the HP NetServer to boot from a PCI-based DAC inserted into a PCI slot. Use the Symbios Configuration Utility to select a different PCI slot when scanning for boot devices.

lSlots 7 and 8 accept universal boards. Universal boards automatically switch to accept power from a +5.0 or +3.3 VDC.

Hot Addition and Replacement of Hot Plug PCI Boards

The PCI Hot Plug option is NOS-dependent. To use the Hot Plug option, the PCI board must have a hot plug compliant driver and a Hot Plug Utility for the respective NOS. The Hot Plug Utility is used to turn power off/on to the PCI slot, while the HP NetServer continues to operate normally.
