# Chapter 2
Installing and Configuring the DAS

This chapter provides the information you need to install the DAS for OMNI software and to configure your system.

# 2.1 Installation Requirements

Review the following hardware and software requirements to ensure that your system is prepared for the DAS for OMNI software installation.

Note Back up the disks on your system before installing this software. This will provide a method to restore your system in the event of an installation problem. The procedure for backing up disks is described in the OpenVMS System Management Utilities Reference Manual.

## 2.1.1 Hardware Requirements

The DAS for OMNI software communicates to MMS devices over a full ISO/OSI seven layer stack using an 802.3 Ethernet Bus network. SINEC-S7/AP/H1 devices communications uses the first four layers of the ISO/OSI stack over an 802.3 Ethernet network. SINEC-S7 also supports communnications using RFC-1006 (OSI over TCP/IP). You will require the appropriate OpenVMS communications network interface and/or bridges to connect the OpenVMS system and MMS/SINEC-S7/SINEC-AP/SINEC-H1 devices together. The same OpenVMS 802.3 Ethernet interface may be used for both DECnet and MMS/SINEC-S7/SINEC-AP/SINEC-H1 communications.

The hardware requirements for the DAS for OMNI software are the same as those for BASEstar Classic. For specific hardware requirements, see the BASEstar Classic Installation Guide.

## 2.1.2 Software Requirements

Before installing the DAS for OMNI software, the following software must already be installed: 1

- OpenVMS Version 5.5-2 or higher (VAX)
- OpenVMS Version 6.1 or higher (Alpha)
- DECnet/OSI (DECnet-Plus) Version 5.6B or higher (VAX)1
- DECnet/OSI (DECnet-Plus) Version 5.7 or higher (Alpha)1
- OSI Session Application Kernel (OSAK) Version 3.0
- OMNI for OpenVMS Version 2.0A or higher (VAX)
- OMNI for OpenVMS Version 2.1 or higher (Alpha)
- BASEstar Classic for OpenVMS, Version 3.4 or higher

If BASEstar Classic for OpenVMS is not already installed on your system, see the BASEstar Classic Installation Guide.

Note Before using this product on a system, you must first register a License Product Authorization Key (License PAK) using the License Management Facility (LMF). For more information about the License Management Utility, refer to the License Management Utility Manual for OpenVMS.

## 2.1.3 Additional Software Requirements

In order to support the Siemens SINEC-S7, SINEC-AP or SINEC-H1 functions, the following software must also be installed: 1

- OSAP/S7 Version 3.1 or higher
- OSAP/AP Version 2.0B or higher1
- OSAP/H1 Version 2.0B or higher1

If using OMNI software version 3.0 or later, the following software must also be installed to support MMS functions:

- OMNI-MMS Version 3.0 or higher

## 2.1.4 Disk Space Requirements

Table 2-1 lists the disk space required to install the DAS for OMNI software. The space requirements are approximations; actual sizes may vary depending on your system environment, configuration, and software options installed.

Table 2-1 Disk Space Requirements
Usage | Approximate Space Requirements
--- | ---
Peak (during installation) | 1000 blocks (VAX)
| 2250 blocks (Alpha)
Net (after installation) | 650 blocks (VAX)
| 1100 blocks (Alpha)

Note #### 1 Refer to the DECnet-Plus for OpenVMS Installation and Configuration to determine the minimum version of DECnet-Plus required for the version of OpenVMS software installed. #### 1 Refer to the OSAP/VMS Installation Guide to determine the minimum version of OMNI or OMNI-API required for the version of OSAP software installed.
