U320 SCSI Enablement and Conversion
Procedures

Introduction

This chapter explains how to upgrade the SCSI cards to enable U320 operation and how to optionally change
the SCSI configuration (duplex to simplex) in your hp Server. The U320 enablement process involves
replacing the duplex PCA card (duplex configuration only) and the SCSI backplane (simplex and duplex
configurations). Refer to the hp Integrity rx4640 Server Installation Guide for instructions to convert your
server from simplex to duplex operation. After preforming these procedures, you will be directed to start up
your server and resume operation.
The embedded backplane for internal SCSI hard disks drives in the hp integrity rx4640 server may be
configured in either simplex or duplex mode.
In simplex mode, both embedded internal hard disks are on SCSI channel A. SCSI channel B may be used for
external devices. Remove the cover from channel B prior to connecting external devices. Do not connect
external devices to SCSI channel A.
In duplex mode, each hard disk is on a separate SCSI bus. Do not connect external devices to either SCSI
channel A or B.

Time Required

Upgrading your hp Server may require several hours, depending on preparatory time, but you should plan for
an hour of system downtime. Preparatory time includes checking the upgrade kit, preparing an ESD-safe
work station, and backing up your data.

Upgrade Tasks

Upgrade tasks depend on whether the server is configured for simplex or duplex operation. The upgrade
procedures are accomplished as follows:
Simplex Configuration Upgrade
• Back up your data
• Shutdown your server (disconnect AC power)
• Remove server components
• Replace SCSI backplane board
• Install Server Components
• Verify the upgrade installation
Duplex Configuration Upgrade
• Back up your data
• Shutdown your server (disconnect AC power)
• Remove server components
• Remove the SCSI duplex board
• Replace SCSI backplane board
