Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Four- to five-node expansion (shadowed)

Introduction

Determine where the expansion modules should be placed,

according to the Meridian Mail Modular Option EC Site and

Installation Planning Guide (NTP 555-7061-200).

Expanding from a

4-node to a 5-node

shadowed system

To expand from a 4- to a 5-node shadowed system, follow these

steps.

Step Action

1 Power down the system.

Note:

You must properly courtesy down the system before you

can power down. For more information on courtesy down

procedures, refer to the “System status and maintenance”

chapter in the

System Administration Guide

appropriate to your

site.

2 Install the new module. Refer to the section on “Adding a

module to a column” in

SL-1 System Installation Procedures

(NTP 553-3001-210).

3 Remove the EVB terminator, if there is one, from shroud S7 in

module MM1.

4 Insert the CEPS, Enhanced MMP40 board (module MM2,

slot 6), and disk drive (module MM1, slots MSU2 and MSU3)

into node 5 as indicated in “Adding node 5 to a shadowed

system” on page 14-31.

Note:

Before you install the disk units, verify their jumper

settings. Refer to Chapter 7, “Installing the disk drives and tape

drive.”

5 If you have a utility card in module MM1, move it to module

MM2, slot 5. Remove the EVB terminator, if there is one, from

shroud S7 in module MM2.

6 If you plan to have more than 24 ports, install a second network

loop cable from the Meridian 1 switch to the J5 connector on

the backplane of module MM0. See Chapter 11, “Installing the

Meridian Mail to PBX interface.”
