Converting from an existing Modular Option EC system to Release 13 15-3
Before beginning system installation
Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999
Before beginning system installation
Introduction
Before beginning the system installation and modification
procedures, unpack and inspect any new printed circuit packs as
described in Chapter 4. Then refer to the System Installation
and Modification Guide (NTP 555-7001-215) to begin the
conversion.
Enhanced MMP40
For Release 13 of Meridian Mail, an MMP40 or Enhanced
MMP40 card is required on all nodes (one MMP40 or Enhanced
MMP40 card per node). A multi-node system can support a
hybrid of Enhanced MMP40 and MMP40 cards.
Note: If you are upgrading from Meridian Mail Release 9 or
earlier, 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 baud. The most important aspect of
deciding to run at either speed is to ensure that the console or
terminal and modems are set to match the speed of the installed
BootROM.
To facilitate the conversion, a speed change utility is available
either through the Install/data tape during installation, or
through the TOOLS level menu after installation. Use the speed
change utility to select the appropriate speed.
Hardware conversion
requirements
Hardware conversion requirements for Release 13 depend on
whether your system already has Enhanced MMP40 cards
installed. The conversion is also affected by the selected
terminal baud rate (2400 or 9600 bps). See “Hardware
requirements” on page 15-4 for an overview of the hardware
requirements for each conversion scenario.
