7-2 Installing the disk drives and tape drive

Overview

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Overview

Introduction

This chapter provides instructions on how to install disk and

tape drives. You need to install drives in each module of the

system.

Overview of disk

drives

Your system comes with one disk drive for each unshadowed

node and two drives for each shadowed node. Every drive is

labeled for the node it belongs to, and mounts on a disk drive

carrier which also holds the connector to the backplane. Disks

that are in the top disk drive mass storage unit (MSU) slots

(MSU3 and MSU5) contain an auxiliary power pack. This

includes the secondary disk in a shadowed node and the disk in

node 3 of an unshadowed 3-, 4-, or 5-node system.

The system supports 300 Mbyte, 1.0 Gbyte, 2 Gbyte, and

4 Gbyte disk drives. The disk drives, manufacturer model

number, and Nortel Networks Product Engineering Codes

(PEC) are shown in the table “Modular Option EC disk drives”

on page 7-3.

You must verify jumper settings before you install drives. Disk

drive jumper settings are shown in the disk drive illustrations in

this chapter. See “Disk drive diagrams” on page 7-13.

Note: Diagrams of the disk drives are for reference only. These

diagrams are not drawn to scale and do not include details of the

disks that are not relevant to the procedure described.
