Warranty Information
None
System Overview
The DPS8 46/70 is a distributed computer system designed for various applications. It comprises a host system (CPU-E, SCU, IOM) connected to remote systems via a network processor and local data bases. The system supports multiple users and features advanced storage management with virtual memory capabilities. Maintenance is facilitated through a Distributed Maintenance Services (DMS) approach, including remote and on-site contracts.
Key Components
- CPU-E: Central Processing Unit.
- SCU: System Control Unit, managing main memory.
- IOM: Input/Output Multiplexer, handling data interfaces.
- FEP: Front End Network Processor, managing communication.
- Virtual Memory: Disk-based storage for extended address space.
- Real Storage: Main frame memory.
- DPU: Diagnostic Processor Unit for maintenance.
System Operation
The system operates using the GCOS 8 operating system, featuring multidimensional, multi-processing design and dynamic memory management. It supports various peripherals and communication protocols. Maintenance operations include remote diagnostics and on-site support.
Troubleshooting and error codes
| Error Code | Description |
|---|---|
| SOFTWARE "CMD" MODULE ERRORS (R1 = 13XX) | |
| R1 = 1301 | Command Directive invalid |
| R1 = 1302 | Command argument required decimal digit |
| R1 = 1303 | Command argument requires smaller digit |
| R1 = 1306 | Command includes an argument error |
| R1 = 130F | Command error due to missing or faulty argument |
| R1 = 1324 | Command specifies invalid device type |
| R1 = 132A | Command specifies duplicate channel |
| R1 = 1339 | Command device error, cannot read label |
| R1 = 13XX | Other codes (See footnote at bottom of this page.) |
| SMTCS COMMAND PROCESSOR INIT ERRORS (R2 = CDXX) | |
| R2 = CDOC | Fatal I/O error |
| R2 = CDOD | Non-fatal I/O error |
| R2 = CDXX | Other codes (see footnote below.) |
| This is the final stage of bootload. Failures detected during this init phase will halt the DPU with error codes in R1 and R2. To retry, clear R1 and press RUN. (Ref. CMD Error Retry Section 1.8.) | |

| OEC = 06XX | MEMORY MANAGEMENT ERRORS All codes (See footnote or page B-5.) |
| OEC = 08XX | EXEC SERVICE ERRORS OEC = 081E: Unrecoverable media error on roll in/out. OEC 0821: Error loading system overlay. OEC 08XX: Other codes (See footnote on page B-5.) |
| OEC = 16XX | LOADER ERROR OEC 1607: Unrecoverable media error OEC = 16XX: Other codes (See footnote on page B-5.) |
| OEC = DXXX | DYNAMIC MAINTENANCE PANEL ERROR OEC D108: DMP Read task disabled - fatal error OEC D108: DMP Read terminated - DMP unavailable OEC D110: DMP connect timeout; check cables OEC D204: Expected response from DMP not received OEC D801: DMP Read or Write is busy - fatal error OEC DDXX: Unexpected response from DMP |
| OEC = XXXX | OTHER OEC ERRORS REPORTED BY EXEC |
