Two- to three-node expansion (shadowed)

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Two- to three-node expansion (shadowed)

Introduction

Determine where the expansion module should be placed,

according to Meridian Mail Modular Option EC Site and

Installation Planning (NTP 555-7061-200).

Expanding from a

2-node to a 3-node

shadowed system

To expand from a 2- to a 3-node shadowed system, follow these

steps.

Step Action

1 Configure the switch for the TNs that correspond to the added

ports. See Chapter 12, “Configuring the Meridian 1,” for details.

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 Insert the CEPS, Enhanced MMP40 board (module MM1,

slot 6), and disk drives (module MM1, slots MSU2 and

MSU3) into node 3 (Node X/Y) as indicated in

“Adding node 3 to a shadowed system” on page 14-24.

Note:

Before you install the disk units, verify their jumper

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

drive.”

4 If you need extra RS-232 ports, install a utility card (module

MM1, slot 5).

5 Install the EVB cables as shown in “Intermodule cabling for a

two-module system” on page 14-25. If you did not install a utility

card, install an EVB terminator on shroud S7 in module MM1.

See Chapter 9, “Installing intramodule and intermodule

cabling,” for details.
