Chapter 1. Product information
This book provides information needed to install and configure an IBM
ServeRAID-4L Ultra160 SCSI controller (hereafter referred to as IBM ServeRAID-4x
Ultra160 SCSI controller). These high-performance, redundant array of independent
disk (RAID) controllers are ideally suited for data-storage environments that require
superior performance, flexibility, and reliable data storage. (See “Controller features”
for more information.)
You also can use the configuration and reference information in this book to
configure the IBM ServeRAID controllers provided on some IBM Netfinity and PC
Server system boards.
Option package contents
In addition to this book, the ServeRAID option package contains:
vIBM Netfinity ServeRAID-4L Ultra160 SCSI controller
Attention: Do not open the static-protective bag containing the controller until
you are instructed to do so.
vIBM ServeRAID Support CD
See “Obtaining ServeRAID updates”on page 21 and “Chapter 5. Installing
ServeRAID device drivers”on page 35 for more detailed information.
Contact your place of purchase if any items are missing or damaged.

Standard features of the ServeRAID controller are as follows.
Feature ServeRAID-4L
Arrays (max.) 8
Battery-backup cache No
Cache memory 16 MB
Hard disk drives (max.) 15
Logical drives (max.) 8
Microprocessor 100 MHz

Connector locations
This section provides illustrations of the SCSI channel connectors and cable
connectors for the ServeRAID-4L controller.
The light-emitting diodes (LEDs) on the controllers indicate activity on the SCSI
channels and provide diagnostic information for trained service technicians.

ServeRAID-4L controller
The ServeRAID-4L controller has one independent SCSI channel connector:
Channel 1. This SCSI channels supports up to 15 physical devices.
You can attach internal SCSI devices to the Channel 1 connector. You can attach
external SCSI devices to the Channel 1 connector.
Note: The ServeRAID-4L controller uses the module (P/N 38L3386) containing a
lithium battery.
Statement 2:
CAUTION:
When replacing the lithium battery, use only IBM Part Number 33F8354 or an
equivalent type battery recommended by the manufacturer. If your system has
a module containing a lithium battery, replace it only with the same module
type made by the same manufacturer. The battery contains lithium and can
explode if not properly used, handled, or disposed of.
Do not:
vThrow or immerse into water.
vHeat to more than 100 C (212 F)
vRepair or disassemble
Dispose of the battery as required by local ordinances or regulations.

Chapter 2. Installing and cabling a ServeRAID controller
This chapter provides installation and cabling instructions for ServeRAID-4x
controllers.
If you are using a ServeRAID controller on an IBM Netfinity or PC Server system
board, you will not need the information in this section. Continue with “Chapter 3.
Understanding RAID technology”on page 9.
Installing the ServeRAID controller
During the installation, you might need a small, flat-blade screwdriver and the
documentation that comes with your server.
To install the ServeRAID-4x controller:
1. Review “Safety”on page iii and the Safety Information book provided with your
Netfinity server.
2. Turn off the server and disconnect all power cords and cables from the server.
3. Remove the server cover and locate an empty PCI expansion slot for the
controller. Choose a slot that is farthest from other installed components, such
as the microprocessor. If necessary, see your server documentation for more
detailed information about the expansion slots.
Note: For Netfinity 3000 servers, the ServeRAID controllers are supported
only when installed in PCI slot 3. Do not install these controllers in PCI
slots 1 or 2. Before you can install a ServeRAID controller in a Netfinity
3000, you must first remove the standard SCSI controller that comes in
PCI slot 3. You can install and use the standard SCSI controller in PCI
slots 1 or 2, but devices attached to the standard SCSI controller will no
longer provide startup (boot) support.
4. Remove the expansion-slot cover, if applicable.
5. Touch the static-protective package containing the controller to an unpainted
metal expansion-slot cover on the server. This discharges any static electricity
from the package and from your body.
6. Remove the controller from the static-protective package holding the controller
by the edges. Do not touch any exposed components on the controller.
7. Insert the controller in the PCI expansion slot. Press the controller firmly into
the slot so that it is fully seated.

8. Secure the controller by either tightening the expansion-slot screw on the top
of the controller or closing the latch, depending on your server.
9. Connect the SCSI cables to the controller. If you intend to attach external
devices only, go to step 13 on page 7. Otherwise, continue with step 10.
10. Connect one end of a 68-pin ANSI standard cable (separately purchased or
already in your server) to the internal channel connector on the ServeRAID
controller.
Note: See “Connector locations”on page 3 for the channel connector
locations.
1. ANSI stands for American National Standards Institute.
