Converting from an existing Modular Option EC system

Introduction

If you are converting to Release 13 from an existing Modular

Option EC 68K or MMP40 system, run Comprehensive

upgrade.

Conversion to Release 13 requires replacement of the 68K CPU

card with the Enhanced MMP40 card on all nodes. The

Enhanced MMP40 card allows the system to be upgraded to run

at 9600 bps. This upgrade is optional as the system will run at

2400 bps. The most important aspect of the decision to run at

either speed is to ensure that you set the console/administrative

terminal and modems to match the speed of the installed

BootROM.

Tandberg tape drives are available (but not mandatory) for

Release 13. They provide greatly enhanced speed and storage

capacity. The Archive Viper tape drives are still supported, but

if you decide to use the new Tandberg drive, refer to Chapter 7,

“Installing the disk drives and tape drive,” for replacement

instructions.

Before you begin the system installation and modification

procedures, unpack and inspect the new hardware as described

in Chapter 4, “Unpacking and inspecting the equipment.” Then

refer to the System Installation and Modification Guide to begin

the conversion to Release 13. When the System Installation and

Modification Guide instructs you to “install the new hardware,”

refer to Chapter 15, “Converting from an existing Modular

Option EC system to Release 13,” for instructions.

Note: You cannot revert to an earlier version of the Modular

Option EC system once you have converted the system to

Release 13.

Node expansion on an

existing system

To perform a node expansion (add nodes to an existing system),

you need to use the system installation and modification

program on the Install/data tape. The “Comprehensive

Upgrade” chapter in the System Installation and Modification

Guide (NTP 555-7001-215) discusses all the necessary steps for

node expansion. When necessary, the System Installation and
