vi IBM EXP400 Storage Expansion Unit Type 1733: Hardware Maintenance Manual and Troubleshooting Guide

Chapter 1. General information
The IBM EXP400 Storage Expansion Unit, referred to in this manual as expansion
unit, provides high-capacity, small computer system interface (SCSI) disk storage. It
supports up to seven Ultra320 SCSI hard disk drives on each half of the dual bus. It
delivers fast, high-volume data transfer, retrieval, and storage functions across
multiple drives, to multiple hosts. The expansion unit is designed for continuous,
reliable service; the modular, redundant disk drives, power supply with fan units,
and SCSI Bus Expander and Enclosure Services Module (referred to in this book as
ESM) use hot-swap technology for easy replacement without turning off the
expansion unit. For more information, see “What your expansion unit offers” on
page 4.
Expansion unit models 1RU and 1RX come with two 500-watt ac power supply with
fan units, one ESM (the second ESM is optional), a filler panel to cover the empty
ESM bay, and 14 drive filler panels. Expansion unit model 2RX comes with two -48
volt dc power supply with fan units, two ESMs, and 14 drive filler panels. The drive
filler panels are replaced with hard disk drive options.
