Chapter 1 Introduction The Compaq KZPEA adapter is a 64-bit/66 MHz PCI, dual-channel Ultra3 SCSI controller that interfaces directly with a Peripheral Component Interface (PCI) local bus. It supports both external Compaq StorageWorks or internal storage devices on AlphaServers and workstations, per LVD Ultra3 SCSI channels. The adapter supports no more than 15 SCSI drives per channel or 30 SCSI drives per adapter.
Physical Description The KZPEA adapter components are mounted on a 4-inch by 7-inch printed circuit board that is inserted in a PCI expansion slot on the host computer motherboard. Figure 1–1 KZPEA Adapter Wide Wide Channel B Channel A End View...

The KZPEA adapter has the following features: • Self-resetting term power. • Multiple Logical Unit Numbers (LUNs) for robotics control commands. • Onboard NVRAM and SCSI Utility. • PCI 2.2 compliant. • Supports universal 32-bit PCI and universal 64-bit PCI.
Fast-SCSI-2 devices. The KZPEA adapter can support several different SCSI devices at one time. The KZPEA adapter interface to the server processor is the PCI local bus. The PCI bus is a high-performance, 64-bit bus with multiplexed address and data lines.
1.3.1 SCSI Channel Assignments SCSI channel 1/A and SCSI channel 2/B of the KZPEA adapter each support one external VHDCI connector or internal 68-pin HD SCSI connector. SCSI channel 1/A also has a 50-pin SCSI connector for CD-ROMs and tape support.
1.3.3 Multiple Adapter Installation The following considerations apply when you install more than one KZPEA adapter: • Each adapter has two independent SCSI channels. Each channel supports up to 15 drives. • Each SCSI channel has its own set of unique SCSI IDs (from 0 to 6 and 8 to 15).
Cables are provided with most Compaq server products that require cabling. If you find that you need an additional cable or that one was not provided with your server product, you can order the necessary cables from your local Compaq Reseller or authorized Compaq Service Provider. See Table 1-2 for external cable part numbers.
1.3.6 SCSI Cable Connectors To identify the various SCSI cables required for installing a KZPEA adapter in various configurations of Compaq AlphaServers and workstations, see Figure 1-2. Figure 1–2 SCSI Cable Connectors External 68-pin wide SCSI connector (Not used on KZPEA) ...
Chapter 2 Installing the KZPEA Adapter This chapter describes installing the KZPEA adapter in AlphaServer systems or workstations. This chapter covers the following topics: • Installation Preparation • Install the KZPEA • Cable the KZPEA WARNING: Many servers are capable of producing energy levels...
Installation Preparation Check system requirements and verify that you have received all items in the KZPEA adapter kit. Perform an orderly shutdown of the system. Prepare the system and adapter for installation. Install and cable the adapter. 2.1.1 System Requirements Table 2–1 KZPEA Requirements...
Each device and host adapter on the SCSI bus must have a unique SCSI ID. It is recommended that the KZPEA adapter be left at its default ID of 7. If it is necessary to change the KZPEA adapter ID, refer to Table 3-1, SCSI Options.
On a 16-bit SCSI bus, each device must have a unique SCSI ID from 0 to 15. Since the KZPEA default ID is 7, all other devices on the bus should be given IDs from 6 to 0 and 15 to 8, with 6 being the highest priority and 8 being the lowest priority.
1. Use an ESD ground strap when handling the adapter module. 2. Locate an available PCI bus expansion slot. Make certain there are no restrictions for the PCI slot into which you will install the KZPEA. See the documentation that came with your AlphaServer or workstation for the location.
5. Install the KZPEA adapter into the PCI slot and press it firmly into place. The contacts on the adapter edge should be fully seated in the system board connector. 6. Depending on your AlphaServer or workstation model, secure the adapter by replacing the retaining screw or by closing the slot latch.
NOTE: With the LED cable connected to the SCSI card, the LED disk activity light may not indicate disk activity on non-SCSI disk drives. Figure 2–3 J3 and J5 Jumpers Installing the KZPEA Adapter...
Cable the KZPEA Each KZPEA adapter channel can be connected to external SCSI devices (located in outside units) or to internal SCSI devices (located in the server). Figure 2–4 SCSI Cables Table 2–3 SCSI Cabling Connector Description VHDCI - VHDCI cable ...
5. Proceed to Section 2.3.2. Replacing the Integrated SCSI Controller If you are replacing the integrated SCSI controller with the KZPEA adapter, proceed as follows: 1. Unplug the original SCSI cable from the system board or original SCSI adapter.
6. To verify your internal/external SCSI devices are available at the console, enter the show config command at the SRM console prompt. Example 2-1 shows a typical show configuration command. See Chapter 4 for a description of the command output. 2-10 KZPEA User’s Guide...

NOTE: The KZPEA must be installed in PCI hose 0 in order to use the Configuration Utility. If your configuration requires having the KZPEA in another PCI hose, install and configure the adapter on hose 0 and then move it to the final PCI position.

This chapter provides some common solutions to problems that can occur when installing the KZPEA adapter. If you experience difficulty in installing or verifying the KZPEA, use the information in this chapter to isolate and diagnose the problem. The troubleshooting techniques described in this chapter do not identify all possible problems with your KZPEA adapter, nor will the actions suggested remedy all problems.

The "Slot" column lists the logical slots seen by the system. These are not necessarily the physical slots into which devices are installed. The Adaptec AIC–7899 is the device used on the KZPEA. Refer to your system documentation for device specifics.

Note that one of the entries, Hose 0, Bus 0, slot 16, consists of two AIC-7899 devices. This entry is the KZPEA host adapter in this system. For later identification of the module, write down the SCSI port names (in this example pkc0 and pkd0).

Determining Which Drives are Connected to the KZPEA Host Adapter Issue the show device dk command and identify all devices on the KZPEA controller. The format for disks is dkcn, where c = controller letter matching pkc0 port, and n = the SCSI ID times 100. For example: DKC0, SCSI DISK on controller port C at SCSI ID 0 and DKD300, SCSI DISK on controller port D.

Appendix A Electrostatic Discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static- sensitive devices.
Page 50
Use a portable field service kit with a folding static-dissipating work mat. If you do not have any of the suggested equipment for proper grounding, have an Authorized Compaq Reseller install the part. NOTE: For more information on static electricity, or assistance with product installation, contact your Authorized Compaq Reseller.
