Chapter 1- Introduction
A. Safety Guidelines
A-1 Electricity Safety
General Electrical Safety Guidelines!

•

Use the exact type of power cords as required.

•Be sure to use power cord(s) that came with safety certiﬁcations.

•

The power cord(s) must be compliant with the AC voltage requirements in your region.

•

Plug the Power cord(s) into a socket that is properly grounded
before turning on the power.

•

Take extra precautionary measures when working with high voltage
components. It is not recommended to work alone.

•

Before removing or installing chassis components, be sure to
disconnect the power ﬁrst. Turn off the system before you disconnect the power supply.

A-2. ESD Safety Guidelines!

Electric Static Discharge (ESD) can damage electronic components. To
prevent damage to your system board, it is important to handle it very
carefully. The following measures are generally sufﬁcient to protect yourequipment from ESD.

•Use a grounded wrist strap designed to prevent static discharge.

•

Keep all components and printed circuit boards (PCBs) in their antistatic bags
until ready for use.

•

Touch a grounded metal object before removing chassis components or themotherboard from the antistatic bag.

•Do not let components or PCBs come into contact with your clothing, which
may retain a charge even if you are wearing a wrist strap.

•

Handle a motherboard by its edges only; do not touch its components, peripheral
chips, memory modules or contacts.

•

When handling processors, chips or modules, avoid touching their pins.

•

Put the motherboard or components back into their antistatic bags when not
in use.

•For the grounding purpose, make sure that your chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners andthe motherboard.

1-4

Chapter 1: Introduction

A-3. General Safety Guidelines!
•

Warning!! Follow the guidelines below to avoid possible
damage to the system or injury to yourself:

To avoid injuries to your back, be sure to use your leg muscles, keep yourback straight, and bend your knees, when lifting the system.

•

After removing the components or chassis covers from the system, placethem on a table for safeguard.

•

Avoid wearing loose clothing to preventing it from coming into contact withelectrical circuits or being pulled into a cooling fan.

•The handles are for sliding the chassis in and out of the racks only. Do
not carry the chassis by the handles.

A-4. Operation Safety Guidelines!

Warning: For proper cooling, make sure to install all chassis covers
before turning on the system. If this rule is not strictly followed, warranty
may become void. Do not open the casing of a power supply. Powersupplies can only be accessed and serviced by a qualiﬁed technician of
the manufacturer. Be sure to follow the steps below to install the chassis
covers:1. Make sure that all components and devices are securely fastened on the chassis
and there are no loose parts/screws inside the chassis.
2. Make sure that all cables are properly connected to the connectors and ports.
3. Use the original screws or fasteners to install the covers to the chassis.
4. Be sure to lock to the chassis or the system to prevent unauthorized access.
5. Please follow the procedures listed in Chapter 2 to install or remove components
to or from the SC818.

A-5. An Important Note to the User:
All images and graphics shown in this manual were based upon the latest chassis Revision available at the time of publishing. The chassis you’ve received may
or may not look exactly the same as the graphics shown in this manual.

Section 2: SCSI (Super) GEM Driver Installation

Instructions for the Windows Operating System
Please refer to the following instructions to install the SCSI GEM Driver
for the Windows operating systems.

(*Note: This driver is not necessary for other Operating Systems. If you
have two HDD backplanes, you will need to install the driver twice.)
The driver is located on the Super Micro motherboard driver CD or is available fordownload from our FTP site: ftp://ftp.supermicro.com/driver/Qlogic/
Follow the instructions below to install this driver to your system.

Installing the driver:
1) Right click on “My Computer” and choose “Property”.
2) Select “Hardware” tab and click on “Device Manager”.
3) Open “Other Devices” or wherever “GEM318” is on.
4) Right click on this device and choose “Property”.
5) Click on “Driver” tab and choose “Update Driver”.
6) Click “Next” 2 times, uncheck both “Floppy disk drives” and “CD-ROM drives”.
Then, select the item- “Specify a location,” and choose “Next”.
7) Click on “Browse” and choose D drive or wherever Supermicro Setup CD isin.
8) Choose “Qlogic” folder and click on “Open”.
9) System will automatically detect GEM318 and install the drive from this pointon.
or,1) Right click the "My Computer" icon on your desktop and choose Properties.
2) Click on the Hardware tab and click on "Device Manager" to bring up the listof system devices.
3) You may see one or two yellow question marks (?) that read QLogic GEM354
or GEM318 SCSI Processor Device. Right click on these, and choose touninstall. If two such question marks are present, uninstall both.
4) Click on Action tab and choose "Scan for Hardware Changes". The Hardware Wizard program should start up. Click "Next".
5) At the ﬁrst prompt, choose “Display a list of known device drivers for thedevice so that I can choose a speciﬁc driver” and click "Next".
6) Choose “Other Devices” and click Next.
7) Choose “Have Disk”, and specify your ﬂoppy drive location in the options
box. Then, click "Next".
8) Highlight “Enclosure Services Device” and click "Next".
9) Ignore the warning prompt by clicking "Yes".

Safety Information and Technical Speciﬁcations
1. Safety Guidelines
To avoid personal injury and property damage, please carefully
follow all the safety steps listed below when accessing your systemor handling the components:

ESD Safety Guidelines
Electric Static Discharge (ESD) can damage electronic components. To prevent damage to your system, it is important to handle it very carefully. The following measures
are generally sufﬁcient to protect your equipment from ESD.
•Use a grounded wrist strap designed to prevent static discharge.

•

Touch a grounded metal object before removing a component from the antistaticbag.

•

Handle the RAID card by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.

•

When handling chips or modules, avoid touching their pins.

•

Put the card and peripherals back into their antistatic bags when not in use.

General Safety Guidelines•

Always disconnect power cables before installing or removing any components
from the computer, including the SCA818S Backplane.

•

Disconnect the power cable before installing or removing any cable from the
SCA818S Backplane.

•

Make sure that the SCA818S Backplane is securely and properly installed on
the motherboard to prevent damage to the system due to power shortage.

An Important Note to the User•

D: GEM 318 (SAF-TE: SCSI Accessed Fault-Tolerant Enclosures)This chip allows the system to use a set of pre-deﬁned SCSI commands to monitor
the status of disk drives and provide disk drive information to the user throughLED indicators and buzzers. (*Note: This function is available only when a RAID
controller with a RAID set is present and enabled. Please refer to the table below
for the information on SAF-TE LED Indicators.)
