Possible Solutions

Probable Cause

Problem

Main CPU1 Err
displayed - The
master cpu on the
Main Control Board
(CPU Board on
A04/A06 drive)
malfunctioned.

1. Verify that EPROM chip on Main Control Board (CPU Board on

A04/A06 drive) is inserted correctly.

2. If problem remains, replace Main Control Board (CPU Board on

A04/A06 drive).

Hardware malfunction.

Main CPU2 Err
displayed - The
slave cpu on the
Main Control Board
(CPU Board on
A04/A06 drive)
malfunctioned.

1. Verify that EPROM chip on Main Control Board (CPU Board on

A04/A06 drive) is inserted correctly.

2. If problem remains, replace Main Control Board (CPU Board on

A04/A06 drive).
