Table 10–2: Installing the KZPSA-BB or KZPBA-CB for Radial Connection to a DWZZH UltraSCSI Hub (cont.)

Step	Action	Refer to:
2	Power down the system. Install a KZPSA-BB	KZPSA PCI-to-SCSI
	PCI-to-SCSI adapter or KZPBA-CB UltraSCSI host	Storage Adapter
	adapter in the PCI slot corresponding to the logical	Installation and User’s
	bus to be used for the shared SCSI bus. Ensure	Guide and KZPBA-CB
	that the number of adapters are within limits for	PCI-to-Ultra SCSI
	the system, and that the placement is acceptable.	Differential Host Adapter
		User’s Guide
3	Install a BN38C cable between the KZPBA-BB	—
	or KZPBA-CB UltraSCSI host adapter
	and a DWZZH port.

_____________________ Notes _____________________

The maximum length of a SCSI bus segment is 25 meters, including the bus length internal to the adapter and storage devices.

One end of the BN38C cable is 68-pin high density. The other end is 68-pin VHDCI. The DWZZH accepts the 68-pin VHDCI connector. The number of member systems in the cluster has to be one less than the number of DWZZH ports.

4	Power up the system, and update the system	Firmware release
	SRM console firmware and KZPSA-BB host	notes for the system
	bus adapter firmware from the latest Alpha	(Section 4.2) and
	Systems Firmware Update CD-ROM.	Section 10.1.4.5

______________________ Note ______________________

The SRM console firmware includes the ISP1020/1040-based PCI option firmware, which includes the KZPBA-CB. When you update the SRM console firmware, you are enabling the KZPBA-CB firmware to be updated. On a powerup reset, the SRM console loads KZPBA-CB adapter firmware from the console system flash ROM into NVRAM for all Qlogic ISP1020/1040-based PCI options, including the KZPBA-CB PCI-to-Ultra SCSI adapter.

5Use the show config and show device console commands to display the installed devices

and information about the KZPSA-BBs or KZPBA-CBs on the AlphaServer systems. Look for KZPSA or pk* in the display to determine which devices are KZPSA-BBs. Look for QLogic ISP1020 in the show config display and isp in the show device display to determine which devices are KZPBA-CBs.
