Guide Overview
Purpose

This guide provides general information on the ZLX graphics
accelerator modules (PMAGC–DA, and PMAGC–EA), and
specific information for servicing the modules. The information
is independent of hardware platform. For hardware installation
information, see your hardware systems documentation.

Audience

This guide is intended for anyone seeking general information
on the ZLX modules, and for Digital service personnel seeking
specific service information.

Contents

This guide provides the following information:

Conventions

•

Description of the module

•

Setting jumpers

•

Installation

•

Confirming proper installation

•

Running self-tests

•

•

Information for Digital service engineers

The following conventions are used in this guide:

lowercase

Lowercase monospaced letters indicate
a command that you must enter exactly
as shown. For example: the show config
command.

CAUTION:

Cautions provide information to prevent
damage to equipment or software. Read
these carefully.

IMPORTANT:

Important notations provide information to
allow your system to work properly.

Description of the Modules
Purpose

The ZLX graphics accelerator modules are TURBOchannel-based
2D/3D graphics accelerators. They enable the use of applications
requiring accelerated 2D or 3D graphics, such as mechanical
CAD, molecular modeling, scientific visualization, simulation,
and animation. When used with the J300 Sound and Motion
module, the ZLX graphics accelerator modules integrate graphics
with multimedia applications.

Monitors

The ZLX graphics accelerator modules support 66 Hz monitors,
such as the VRT19-D and VRT16-D, and 72 Hz monitors, such
as the VRT19-H and the VRT16-H.

Illustrations

The ZLX-L1 and ZLX-L2 modules are shown in Figure 1.
Figure 1 ZLX-L1 and ZLX-L2 Graphics Accelerator Modules

MLO-013087

Setting Jumpers
Two Jumpers

The ZLX graphics accelerator modules contain two configurable
parts, a jumper for selecting the monitor, and a jumper for
updating the EEPROM firmware. The locations of these jumpers
are shown in Figure 2, and Figure 3.

Monitor Jumper

Monitor jumpers allow the ZLX graphics accelerator module to
work with monitors that use 66 Hz and 72 Hz refresh rates. Set
the jumpers as shown in Figure 2.

EEPROM
Jumper

The jumper for the EEPROM is normally in the position shown
in Figure 3. To prevent firmware from being changed, move the
jumper to the other position.

Installation
See the system documentation, or options documentation, that
came with your workstation for installation instructions.
CAUTION: Module Damage
To avoid damage from static discharge, you must wear
an antistatic wrist strap. Instructions for use are on the
strap envelope.

IMPORTANT: Grounding Module
When installing a module inside a system, make sure
that you use the screws that came with the module to
fasten the module to the enclosure, thus grounding the
module.

Confirming Proper Installation
Procedure

To confirm that the module is installed properly, do the following:
Step

Action

Turn on the monitor.

Turn on any peripheral devices connected to the system
unit.

Turn on the system.

Enter the sho config command.

Successful Installation: PMAGC, PMAGC–DA, or PMAGC–EA
appears in the configuration display and no errors are reported.
Unsuccessful Installation: The module designation does not
appear in the configuration display. Move the module to another
slot and try again. If the module still does not appear in the
configuration display, contact your Digital service representative.

Running Self-Tests
Console Mode

Self-tests are run in console mode.
Note
References to slot numbers are used in the examples.
Although a module physically occupies 2 or 3 slots, only
one of those slots is recognized by the system. This is the
slot number that appears in the sho config display.

Command
Format

The command format for running a test is t tc# testname. For
example, for a module residing in TURBOchannel slot 2, to run
the vdac test, type the following at the prompt:
>>> t tc2 vdac

Available
Module Tests

To determine which self-tests are available, type:
>>> t tc2 ?

tc2 is the TURBOchannel slot used for the module.

1 is the test number. If the test has multiple subtests, this is
the subtest that failed.

•

yyyyyy is the specific test failure information

A "Test not found" error uses the following format:
?TNF: testname

testname is the name of the test that does not exist.
If the test generates a bus error, the following message appears:
?UEX: testname

testname is the name of the test that was running when the bus
error was generated.

Firmware
Updates

When updating firmware, the EEPROM jumper must be in the
"Program" position, as shown in Figure 3. To prevent updates,
move the jumper to the other ("Secure") position.
