Safety Precautions
Precautions and Instructions
•The Aurora LS weights over 80 pounds. It is recommended that 2 people are required to
properly move and mount it due to its size and weight.
•Be sure that the rack cabinet into which the subsystem chassis will be installed provides:
sufficient strength and stability and
ventilation channels and airflow circulation around the subsystem.
•INSTALL AURORA IN RACK MOUNTING BEFORE INSTALLING DISK DRIVES
•The Aurora LS RAID subsystem will come with up to twelve (12) drive bays. NOTE: a 13th
drive slot is available but is not used in the present configuration. This drive slot, the
furthest right slot for all drives, must have a empty drive canister in its place. Leaving any
of these drive bays empty will greatly affect the efficiency of the airflow within the
enclosure, and will consequently lead to the system overheating, which can cause
irreparable damage.
•Prior to powering on the subsystem, ensure that the correct power range is being used.
•If a disk or power supply module fails, leave it in place until you have a replacement unit
and you are ready to replace it.
•Airflow Consideration: The subsystem requires an airflow clearance, especially at the front
and rear.
•Handle subsystem modules using the retention screws, extraction levers, and the metal
frames/faceplates. Avoid touching PCB boards and connector pins.
•To comply with safety, emission, or thermal requirements, none of the covers or
replaceable modules should be removed. Make sure that during operation, all enclosure
modules and covers are securely in place.
•Provide a soft, clean surface to place your subsystem on before working on it. Servicing
on a rough surface may damage the exterior of the chassis.
•If it is necessary to transport the subsystem, repackage all disk drives separately. If using
the original package material, other replaceable modules can stay within the enclosure.
•
ESD Precautions
Observe all conventional anti-ESD methods while handling system modules. The use of a
grounded wrist strap and an anti-static work pad is recommended. Avoid dust and debris or
other static-accumulative materials in your work area.

Introduction and Overview
1.0 Introduction and Overview
1.1 Product Specifications
1.1.1 Overview
The Aurora LS model the newest member of the Galaxy family of RAID Storage System
products. It is a (4U) rack mount solution that is designed for your ultra high speed data
storage needs.
As with the earlier Galaxy® RAID products, the Galaxy® Aurora LS is characterized by many
of the same outstanding features and attributes as those of other RAID family members. The
most noticeable feature is that this RAID is blazingly fast while being surprisingly affordable.
Other features include a preloaded Linux operating system and RAID Engine Software called
EOS, or NumaRAID , which does all the work of a normal RAID controller without the cost and
dependency of other ASIC based controllers. Of course speeds that exceed 1000Mbytes/
second would be no good without the host connectivity which is built into the unit. Aurora LS
is capable of supporting 1/2/or 4 port 8Gb Fibre Channel HBA [ host bus adapter ] with
connections to 1,2, 4 hosts directly or with SAN connectivity connect to many more. Optical
cable connectivity is available in various lengths to make direct or SAN switch connections
easy. Other features include, easy to use GUI storage management tools, integrated software
functions that help ease configuration and use, ease of deployment in the network, as well as
built-in tools to facilitate remote management and systems management. Our ultra quiet “dark
space” design gives a very low noise signature. The innovative approach to fast RAID rebuild
translates into a 100% of the rebuild occurring in 20% of the time a hardware based RAID
would take. A major feature is only seen during the rebuild: no bandwidth performance loss.
1.1.2 Basic Features and Advantages
Galaxy® Aurora LS RAID products provide these important features and advantages:
Compact 4RU Steel and Aluminum Alloy enclosure with rack mount kit.
1000+ MB/s sustained bandwidth over 8Gb Fibre cables

the AC outlet. To remove a power supply module, you will have to gain access to the mounting
screws inside the chassis. Contact Tech support for help with the removal procedure.
The two round connectors [K] [L] are for a PS/2 keyboard or a mouse. The green connector is
for a mouse, and the purple connector is for a keyboard. To the right of these two connectors
are USB connectors. These can be used for USB drive(s), memory key(s), hub(s), and/or a
USB keyboard or mouse. To the right of the USB connectors is a green serial connector. It is
not used. To the right of the serial connector is an analog VGA connector. You may attach a
console monitor here. To the right of the VGA connector are two gigabit Ethernet ports. The
left port (if you are facing the rear) is port 1, the right port is port 2.
The vertical slits on the right (called slots) hold the host adapters which are inside the system.
Going from left to right, we see an empty slot, then the Fibre Channel host bus adapters [used
to connect to your host system], with two LEDs associated with each connector; one LED
indicates 4Gb host connectivity, two LEDs indicate 8Gb connectivity. Each Fibre connector
can be connected to a unique host system. Next to the Fibre HBA are empty slots, followed
by a SAS RAID Controller card that the 12 Disk drives are connected to. Be aware that a
green LED blinks continuously indicating the processor on the adapter is functioning. The
other blinks during activity.

1.3.3 RAID storage specifications
The Aurora LS has a sophisticated built in RAID software and drives that are pre-configured
and prepared for you so it would be plug and play for most users. By default, the Aurora LS
RAID has been configured into one RAID 6 logical volume. For 32 bit Windows XP
configurations, multiple 2TB volumes would have been created for you.
RAID 6 with its dual parity drive protection has been found to be the most protective and least
costly way of guarding against not only initially failed SATA disk drives but primarily against
the total loss of the RAID data because a second SATA drive detects an error during the RAID
rebuild process. A RAID 5 configuration in that scenario would cause the RAID not to rebuild
properly.
1.3.4 Embedded OS features
Important: The Aurora LS EULA restricts you, the user, from loading any other software,
such as application software, onto the Aurora LS. Tampering with, loading or using any
other software voids the license agreement.
Each Aurora LS is preloaded at the factory with its base operating system, RAID application,
installation, administration and optional SAN software. The code is loaded onto the system's
boot drives.
In addition to the operating system and basic EOS embedded application software, each unit
contains a web based browser interface which simplifies remote configuration and
administration tasks.
Specifically, the units come preconfigured with the following functions:
EOS: Linux based RAID application and User configuration / troubleshooting interface
Remote system administration:
Administrative tasks can be performed in the Web-based GUI
Alternate administrative task performed using Windows Terminal Service
Advanced management functions available via Windows Terminal Service
Optional SAN Management Software
1.4 Mounting / Securing Aurora LS
1.4.1 Rack Mounting the Aurora LS
The Aurora LS is a rack mounted chassis. Mounting holes on the front panel are set to
RETMA spacing and will fit into any standard 19” equipment rack.
Rack Equipment Precautions

GALAXY® AUROURA LS CONFIGURATION AND SYSTEM INTEGRATION GUIDE
18 Section 1 Intro and Overview
These precautions and directions should be used only as an information source for planning
your Aurora LS deployment. Avoid personal injury and equipment damage by following
accepted safety practices.
Floor Loading
CAUTION: Ensure proper floor support and ensure that the floor loading specifications are
adhered to. Failure to do so may result in physical injury or damage to the equipment and the
facility.
Deployment of rack servers, related equipment, and cables exceeds 1800 pounds for a single
42U rack.
External cable weight contributes to overall weight of the rack installation. Carefully consider
cable weight in all designs
Installation Requirement
CAUTION: Be aware of the center of gravity and tipping hazards. Installation should be
such that a hazardous stability condition is avoided due to uneven loading. We recommend
that the rack footings extend 10 inches from the front and back of any rack equipments 22U or
higher.
Adequate stabilization measures are required. Ensure that the entire rack assembly is properly
secured and that all personnel are trained in proper maintenance and operation procedures.
Tipping hazards include personal injury and death.
Power Input and Grounding
CAUTION: Ensure your installation has adequate power supply and branch circuit
protection.
Check nameplate ratings to assure there is no overloading of supply circuits that could have
an effect on over current protection and supply wiring. Reliable grounding of this equipment
must be maintained. Particular attention should be given to supply connections when
connecting to power strips, rather than direct connections to the branch circuit.
Thermal Dissipation Requirement
CAUTION: Thermal dissipation requirements of this equipment deployment mandate
minimum unrestricted airspace of three inches in both the front and the rear. The ambient
within the rack may be greater than room ambient. Installation should be such that the amount
of air flow required for safe operation is not compromised. The maximum temperature for the
equipment in this environment is 122°F (50°C). Consideration should be given to the
maximum rated ambient.
1.4.2 Installation Sequence
CAUTION It is strongly recommended to securely fasten the mounting rack to the floor or
wall to eliminate any possibility of tipping of the rack. This is especially important if you decide
to install several Aurora LS chassis’ in the top of the rack.
A brief overview of Aurora LS installation follows:
1. Select an appropriate site for the rack.
2. Unpack the Aurora LS and rack mounting hardware.
3. Attach the rack mounting hardware to the rack and to the Aurora LS.

GALAXY® AUROURA LS CONFIGURATION AND SYSTEM INTEGRATION GUIDE
19 Section 1 Intro and Overview
4. Mount the Aurora LS into the rack.
5. Connect the cables.
Decide on an appropriate location for the Galaxy Aurora LS . It is best if the unit is kept away
from heat or from where high electromagnetic fields that may exist. If you are installing the unit
into a rack, make sure the rack is in the proper location prior to installation. Moving the Galaxy
Aurora LS while it is installed into the rack is not recommended.
The Galaxy Aurora LS , requires 4 rack units of vertical clearance (7 inches), and a depth of
28 inches. It is recommended that you mount it in a rack which is at least 30 inches deep.
Airflow for the unit comes in through right side and the front. Heat exhaust is from the rear of
the unit. It is important that airflow at the front or the rear not be blocked.
The rack slides permit the unit to slide out of the front of the rack. There are latches on the
sides of the slides, and if you are planning on removing the unit from the rack to service or
transport it, sufficient clearance should be available to allow you to activate the latches and
unlatch the slides.
If the rack is on wheels, be sure to use the wheel locks when installing or removing the Galaxy
Aurora LS from the rack. If the rack does not have wheel locks, place something against the
wheels to prevent movement, or if your rack is equipped with leveling jacks, extend the jacks
to make sure the rack stays level during installation. Always make sure the rack is completely
immobile before installing or removing any components. Never extend more than one
component from the rack at the same time.
There is a set of slides included with the Galaxy Aurora LS . The slides are required for rack-
mounting the unit, and the slides must be mounted with the rear extensions installed into the
rack. The weight of the unit is sufficient that if this were not performed, damage would result to
the unit, the slides, or the rack if installed.
When installing the slides, loosely attach the rear end of the slide to the front end, then screw
the front and rear rack portions of the slides into the rack. Finally, tighten the screws between
the two ends. Repeat this process for the other side. Once the slides are installed in the rack,
slide the unit into the slides. Slide extensions are included in case the rack is deeper.
1.4.2.1 Ball Bearing Slide Rail Rack Installation
Unpack the package box and locate the materials and documentation necessary for rack
mounting. All the equipment needed to install the server into the rack cabinet is included.
Follow the instructions for each of these illustrations
