Chapter 1. Introduction
The 5194 Network Attached Storage Model EXU Storage Unit is a compact unit that
provides high-capacity, small computer system interface (SCSI) disk storage. It
supports 14 36.4 GB 10K rpm Ultra160 SCSI drives on a single logical bus. It
delivers fast, high-volume data transfer, retrieval, and storage functions across
multiple drives. The storage unit is designed for continuous, reliable service; the
modular, redundant disk drives, power supplies with built-in fans, and environmental
services monitor (ESM) boards use hot-swap technology for easy replacement
without turning off the engine to which the storage unit is attached, and in some
cases, without turning off the storage unit.
The storage unit supports IBM Ultra160 SCSI for the host and drive interfaces and
is designed for easy installation and integration into a variety of system
environments.
After you review the introductory information provided in this chapter, see
“Chapter 2. Installing the storage unit”on page 9 to begin the installation process.

unit. Therefore, you can maintain the availability of your system while a hot-swap
device is removed, installed, or replaced. See “Chapter 3. Installing and replacing
devices”on page 21 for more information.
Hot-swap drive bays
The following illustration shows the location of the hot-swap drive bays accessible
from the front of your storage unit. The storage unit supports 14 IBM Ultra160 SCSI
hard disk drives. These drives come pre-installed in a drive tray. The drive and tray
assembly is called a drive CRU (customer replaceable unit). You can install the
drive CRUs in the 14 drive bays on the front of the storage unit.
Attention: Never hot-swap a drive CRU when its green activity light emitting
diode (LED) is flashing. Hot-swap a drive CRU only when its amber fault LED is lit
(not flashing) or when the drive is inactive with the green activity LED off (not
flashing).
Bridge card bay
The bridge card is accessible from the front of the unit. You can replace the bridge
card CRU, but you must turn off the storage unit before doing so. See “Replacing a
bridge card”on page 23 for step-by-step instructions.
Attention: Never remove the bridge card while the storage unit is turned on. See
“Turning the storage unit on and off”on page 17.
ESM and power supply bays
The following illustration shows the location of the environmental services monitor
(ESM) bays (for the hot-swap ESM boards) and the power supply bays where the
hot-swap power supplies are located.

Hot-swap power supply/fan bays
Hot-swap ESM bays
25194 Network Attached Storage Model EXU Installation and User’s Guide

Hot-swap power supply/fan bays
Your storage unit comes with two 500 Watt hot-swap and redundant power
supplies with built-in fans. The power supplies are redundant in that a single
power supply can provide adequate power and cooling for the entire
storage unit. A single power supply supports 14 hard disk drives; however,
both power supplies must be installed, even if one power supply is not
operational. See “Working with hot-swap power supply/fan units”on
page 26 for step-by-step instructions.
Switch card bay
Your storage unit comes with a switch card that contains five external option
switches and four internal option switches. The switch card is located on the back
of the storage unit between the two power supplies. The switch card contains
switches that control how power is supplied to the storage unit and what storage
unit services are enabled. The internal option switches are preset to the default
position (Off). To access the four internal option switches, you must turn off the
storage unit; then remove the switch card. See “Replacing the switch card”on
page 24 for step-by-step instructions.
Attention: Never remove the switch card or change the switch card settings
while the storage unit and host server is turned on. Refer to “Turning the storage
unit on and off”on page 17.
In addition to the internal and external option switches, the switch card also has a
10-position unit ID switch for setting the storage unit ID using values 0 through 9.
System-management software, such as IBM Netfinity Manager
™
, uses the ID when
it provides data and alerts for the storage unit.
For more information on option switch settings, see “Setting the interface options
and ID settings”on page 11.
The following illustration shows the location of the switch card on the storage unit.

–IBM Safety Book
–Template for installing the storage unit in a rack
If an item is missing or damaged, contact your IBM reseller or your IBM marketing
representative.
If you have not already done so, take a moment to review the information in this
chapter and record your storage unit serial number in the table in “Identification
numbers”on page 35. Then, return to this chapter to begin the installation process.
Getting started
Before you begin, review the following assumptions:
vIf you are installing the storage unit in a rack, you have already installed the
other components in the rack and moved the rack to its permanent operating
location.
vThe installation site meets all area, environmental, power, and site requirements
for the storage unit. See the storage unit requirements listed under “Operating
specifications”on page 9.
Preparing the storage unit
This section explains how to remove the CRUs and set the option switches to
prepare the storage unit for installation.
Removing CRUs
Attention: Static electricity, though harmless to you, can seriously damage
storage unit components or options. See “Handling electrostatic discharge-sensitive
devices”on page 54 for details.
Attention: If you have data stored on the drives, label the drives before you
remove them. Then, when you replace the drives, install each one in the same
drive bay from which you removed it. Failure to do so could result in a loss of data.
See “Chapter 3. Installing and replacing devices”on page 21 for information on
removing the CRUs.
It is easier to lift the storage unit and install it in a rack if you remove all CRUs (disk
drives, power supplies, and ESMs) first. A fully loaded storage unit with 14 hard disk
drives and two power supplies installed weighs 36.1 kg (79.5 lb). If you remove all
the CRUs, you can reduce the overall weight.
