------------------------------------------------------------ Preface Use this guide to install one or more BA42 DSSI expanders, to add a drive to a BA42 DSSI expander, and to verify that DSSI switches have been set correctly for each drive in a BA42 DSSI expander. This guide describes the following: · How to install one or more expanders · How to install new drives inside BA42 DSSI expanders · How to make sure the drives inside a BA42 DSSI expander are recognized by the system and what to do if they are not vii 1 ------------------------------------------------------------ Installing the BA42 DSSI Storage Expander This chapter covers the following topics: · Checking the shipment to make sure nothing is broken or missing · Setting up a BA42 DSSI expander · Selecting DSSI ID numbers and setting the DSSI ID switches for Digital-supplied hard disk drives installed in the BA42 expander · Attaching the expander to the system unit · Attaching one expander to another expander · Ensuring that the system recognizes the drive or drives inside the expander 1.1 Checking the Shipment When you unpack the carton that contains a BA42 DSSI expansion box, you will find all of the items shown in Figure 1-1. Installing the BA42 DSSI Storage Expander 1-1 Installing the BA42 DSSI Storage Expander 1.1 Checking the Shipment Figure 1-1 Parts of a BA42 DSSI Expander Box Shipment ! Documentation " DSSI expander box # Rubber drive shipping bracket supports (up to three) $ DSSI terminator % DSSI cable & Power cord (In Europe the power cord may not be included; it is an optional item which may be ordered from a menu.) 1-2 Installing the BA42 DSSI Storage Expander Installing the BA42 DSSI Storage Expander 1.2 Setting Up the Expander 1.2 Setting Up the Expander ------------------------------------------------------------ Warning ------------------------------------------------------------ It takes two people to unpack and set up a BA42 DSSI expander safely. ------------------------------------------------------------ ------------------------------------------------------------ Caution ------------------------------------------------------------ Standing an expander on its side blocks vents and can damage the expander and any drives it contains. ------------------------------------------------------------ Set up the BA42 DSSI expander on a flat surface as near as possible to the system unit. If you are installing more than one expander, you can stack the boxes on top of each other. Make sure the on/off switch on the expander is in the off position (see Figure 1-2). Installing the BA42 DSSI Storage Expander 1-3 Installing the BA42 DSSI Storage Expander 1.2 Setting Up the Expander Figure 1-2 On/Off Switch in the Off Position ! On/off switch 1.3 Determining Which DSSI ID Numbers Are Available A DSSI ID number must be designated for the first drive installed in a BA42 expander; the DSSI IDs for the remainder of the drives in the expander will be set automatically in increments of one, beginning with the number assigned to the first drive. Numbers that can be used range from 0 to 7 (up to seven DSSI drives can be connected to a given DSSI connector on the system unit); each number may be used only once via that connector. To find out what DSSI ID numbers are available, see the option installation instructions in the installation guide or user 's guide for the system. After determining the DSSI ID number to be assigned to the first drive, use the DSSI ID switches on the rear of the expander box to set the ID to that number (see Section 1.4). 1-4 Installing the BA42 DSSI Storage Expander Installing the BA42 DSSI Storage Expander 1.4 Setting DSSI ID Switches for Hard Disk Drives 1.4 Setting DSSI ID Switches for Hard Disk Drives The DSSI ID switch for hard disk drives installed in a BA42 expander is located on the back of the expander. If there are one to four hard disk drives preinstalled in your expander, check the DSSI ID switch setting for the first drive and change the setting if necessary. Settings for the remaining hard disks are then automatically incremented. 1.4.1 Remove the DSSI ID Switch Cover from the Expander Access the DSSI ID switches by lifting up and removing the switch cover (see Figure 1-3). Replace the switch cover after checking the switches or the drive indicator LEDs.

The DSSI IDs for additional hard drives are automatically incremented by one as they are added; no further action is necessary. 1-6 Installing the BA42 DSSI Storage Expander Installing the BA42 DSSI Storage Expander 1.4 Setting DSSI ID Switches for Hard Disk Drives Figure 1-4 LED Indicators and DSSI ID Switches for Hard Disk Drives ! LED indicators " DSSI ID switches 1.4.3 Change the DSSI ID Switch Settings if Necessary Normally the three switches are preset at the factory to the ID number zero, with all three switches set to open (down, down, and down). However, if the expander is ordered with a CPU that has storage embedded, the ID of the system disk drive in the CPU is set to zero and the first drive in the expander box is the first available ID outside of the CPU cabinet. If necessary, use a pen or small pointed object to flip the switches to set the DSSI ID of the first drive to the appropriate number (see Table 1-1).
