Installation
This chapter describes:
• Before you begin
• Safety considerations
• Installation checklist
• Connectors, Jumpers, LED’s
• Controller installation
• SCSI cabling and termination
• SCSI IDs
• Limitations on mixing SCSI drive types
Mylex disk array controllers are designed to work in a variety of SCSI RAID
application environments. Certain configuration steps need to be performed
prior to installing the controller into a RAID environment. Each of the steps
described in this chapter are part of the installation process.
Manual No. 775051 2-1
Before You Begin
Before You Begin
Installing the AcceleRAID 352 Dual Channel RAID controller is no more
difficult than installing any 32-bit or 64-bit PCI adapter. The AcceleRAID
352 dual channel controller connects into any PCI slot (PCI 2.1 or 2.2
compliant) on the motherboard. Follow these steps and the installation
procedures in this chapter.
WARNING
Working with the system covers off and power
applied to the system can result in shock and
serious injury.
This controller is furnished with a nonvolatile
RAM (NVRAM) chip that uses a sealed lithium
battery/crystal module. Replace the module only
with the same or equivalent type recommended by
the manufacturer.
Dispose of the used battery/crystal module
according to the manufacturer’s instructions.
Never incinerate a battery as it could explode and
cause serious injury.
1. Power off the system and disconnect the power cables before starting
the installation. Refer to the instructions provided in your system
documentation. Do not disconnect cables or power cords while system
power is on.
2. Read all of the instructions in this chapter completely before proceeding. Follow the Notes, Cautions, and Warnings described in this manual
and marked on the equipment.
3. Follow electrostatic discharge (ESD) safe procedures. Use a grounded
wrist strap or ESD safe footwear, and work in an ESD safe area.
4. Perform a safety check of the installation before powering on the
system.
• Make sure that the cabling Pin 1 location is correct and that all
cables are firmly seated in the connectors.
• Make sure all SCSI conventions (cable type, cable length,
termination, etc.) are correct, see Table 2-5.

Installation
Safety Considerations
Be sure to observe the following precautions before beginning the controller
installation procedure:
Caution
Anti-static handling procedures are required. Leave
the controller in its anti-static bag until it is time to
plug the controller into the PCI slot. The use of a
grounded wrist strap and other ESD protective
measures are highly recommended.
WARNING
Disconnect the system from the electrical wall
outlet before opening the system cabinet. Working
with the system covers off and power applied to the
system can result in shock and serious injury.

Installation Checklist
Installation Checklist
GET READY
☛ Note
It is recommended that you wear a grounded wrist
strap when working with hardware installation
procedures.
1. ____ Power off your computer system.
2. ____ Decide which available PCI slot will be used.
3. ____ Remove the plate from the I/O access port to the PCI slot.
4. ____ Remove the AcceleRAID 352 controller from the anti-static bag.
GET SET
5. ____ Plug the AcceleRAID 352 controller into a standard PCI slot
(PCI 2.1 or 2.2 compliant--if using hotplug feature, must be 2.2).
6. ____ Tighten the AcceleRAID 352 controller into the mounting
bracket.
7. ____ Connect the SCSI cable(s) from your drive(s) and/or device(s) to
the desired SCSI channel.
8. ____ Check SCSI termination for internal and/or external devices.
9. ____ Check disk drives. Be sure termination is set to the disabled
position on any disk drive(s) that will not be terminated. For more
information, see the documentation that accompanied the disk
drives.
10. ____ Set SCSI ID on the disk drive(s).
11. ____ Enable termination power on disk drive(s).
12. ____ Safety check the installation.
☛ Note
Review Figure 2-1 and Table 2-5 to get familiar with
the layout of the AcceleRAID 352 controller and the
Connectors, Jumpers, and LED descriptions.

13. ____ Go to Chapter 3, Controller Start-up.
2-4 AcceleRAID 352 Installation Guide
Installation
Connectors, Jumpers and LEDs
There are two external Ultra 160 SCSI channels (connectors) supported on
the controller as shown in Figure 2-1.
SCSI jumpers should normally be set to their default settings, no adjustments
are needed. Default jumper locations are shown in Figure 2-2 and are
described in Table 2-1.
The AcceleRAID 352 controller has one LED on the front side as shown in
Figure 2-3 and described in Table 2-2.
There are four LEDs on the back of the controller that are mode indicators
while the controller is running, shown in Figure 2-4 and described in Table
2-3.
The LEDs indicate single ended, LVD, and FAIL modes.
In addition there is a six-pin header. Figure 2-4 identifies the location of each
pin. Table 2-4 identifies the function of each pin: 3.3V power, Channel 0
and Channel 1 SCSI activity, cache dirty status and, a ground pin.
When you have checked the termination requirements, completed the
connections of your desired SCSI devices and other possible devices such as
a CD-ROM drive or a tape drive, close your system with the cover.
PCI Hotplug
☛ Note
Please see Appendix D for information on how to
implement the Hotplug feature for your system’s
requirements.

Manual No. 775051 2-11
Installation Process
☛ Note
In order to ensure an error free environment, the
proper cable type designed for a certain SCSI
speed must be used, please refer to Table 2-5 on page
2-17.
☛ Note
It is recommended that non-RAID SCSI devices be
connected to a separate SCSI channel, either on the
system board or furnished by a SCSI host bus adapter.
☛ Note
To avoid problems caused by mixing drive types,
please refer to “Limitations on Mixing SCSI Drives”
on page 2-18.
