About the A5159B Adapter

The A5159B PCI Dual Port Fast/Wide/Differential (FWD) SCSI host bus adapter is a PCI (peripheral component interconnect) controller card that provides an interface between HP servers or workstations and SCSI storage devices. The adapter supports bootable devices and can be used with disk drives, tape drives, and other SCSI devices.

	NOTE: The A5159B adapter is a High Voltage Differential (HVD) type and cannot support single-ended (SE) mechanisms.

This guide is for qualified personnel who maintain or service HP servers or workstations. Installing the adapter requires proficiency in both hardware configuration and software administration.
