Preparing to Install VME Options
1-2
014–001867
1. Plan your system configuration and work site. Chapter 1 provides step-by-step
instructions and worksheets to help you with this process.
2. Configure the board. Chapter 2 describes how to set jumpers and switches; it
also contains tables indicating how to correctly jumper the boards for a
DG/UX

operating system environment only. To determine how to configure
the boards for computers that do not use the DG/UX system, you must refer to
the device-specific technical manuals and the operating system documentation.
3. Remove the air dam or cover plate covering the assigned slot in your VME card
cage, and install the option board. Chapter 3 contains the hardware
instructions you need for this step. To complete an installation, you must refer
to your operating system documentation. In addition, for some boards you will
need the appropriate communications software manuals.
4. If necessary, install backplane jumpers. Chapter 3 includes instructions on
backplane jumpering. Your system’s maintaining and/or expanding manuals
describe how to open or remove any panels that prevent access to the rear of the
VME backplane.
5. Connect your external devices to the board in the computer card cage. The
instructions in Chapter 4 of this manual assume that your basic computer
system is already set up, and that all of your external devices are also set up
and ready for installation.
6. If you are adding a VME board to an AViiON computer currently running the
DG/UX operating system, you must rebuild the operating system kernel. Refer
to your DG/UX operating system documentation. If your computer does not run
the DG/UX system, you must refer to the operating system documentation for
your system.
Before you begin any procedure, you should read the relevant sections of this manual to
determine what additional documentation you will need to complete your task. Then
make certain you have all the proper manuals, updates, and Release Notices at hand.
Overview of Pre-Installation Steps
The rest of this chapter covers the following procedures, all of which you should
perform before unpacking or installing a VME option board or assembly:
1. Review your system specifications to ensure hardware and software support for
any planned additions to your computer system.
2. Calculate your system’s power requirements to ensure that the configuration
you plan doesn’t exceed the limits of your power supply.
3. Assign VME card cage slots to your VME boards.
4. Prepare a safe environment for working on delicate electrical components.
The next three sections in this chapter provide rules and guidelines to help you plan
and review the type, number, and arrangement of the various elements that make
up your computer system. We refer to these combined factors as your system
configuration.
The section “Avoiding ESD Damage,” which concludes this chapter, describes
measures you should take to avoid damaging your equipment.
