Safety Precautions
Precautions and Instructions
•Prior to powering on the subsystem, ensure that the correct power range is being used.
•The GalaxyNASLX22 RAID subsystem may come with up to twenty four (24) drive bays.
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.
•If a 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.
•Be sure that the rack cabinet into which the subsystem chassis will be installed provides
sufficient ventilation channels and airflow circulation around the subsystem.
•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.
•Dual redundant controller models come with two controller modules that must be installed
into the subsystem. Single controller models come with a single controller module and a
metal sheet is placed over the lower controller bay at the rear of the subsystem. Since
single controller models cannot be upgraded, this metal sheet should NEVER be removed.
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.

1.3.3 Raid storage specifications
The GalaxyNASLX2 has a sophisticated built in SATA II Raid controller and drives that was
pre-configured and prepared for you so it would be plug and play for most users. By default,
the SATA RAID has been configured into 2TB RAID 6 logical volumes with the guest account
activated and one root level share named galaxynas1[unless otherwise instructed].
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 to fail
and all data would be lost.
LImportant : the RAID controller must be setup to notify the administrator in cases
where errors occur. RAID errors are not posted to the GalaxyNASLX2. Certain RAID
controllers have an audible alarm but the most reliable way to be notified is with email.
This means that the RAID controller’s email notification needs to be setup to warn the
administrator. Follow the procedure in the attached RAID controller’s user guide for
email notification.

GALAXYNASLX2 CONFIGURATION AND SYSTEM INTEGRATION GUIDE
17 Section 1 Intro and Overview
1.3.4 Embedded OS features
LImportant: The GalaxyNASLX2 EULA restricts you, the user, from loading any
other software, such as application software, onto the GalaxyNASLX2. Loading or use
of any software voids the license agreement.
Each GalaxyNASLX2 is preloaded at the factory with its base operating system, installation
and administration software. The code is loaded onto the system's Flash module, a highly
reliable solid state Memory module that is directly connected to the NAS IDE port on the
server board.
In addition to the operating system and basic 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:

1.4 Mounting / Securing GalaxyNASLX2
1.4.1 Rack Mounting the GalaxyNASLX2
The GalaxyNASLX2 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.

GALAXYNASLX2 CONFIGURATION AND SYSTEM INTEGRATION GUIDE
18 Section 1 Intro and Overview
Rack Equipment Precautions
These precautions and directions should be used only as an information source for
planning your GalaxyNASLX2 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.
Rorke Data recommends 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.

GALAXYNASLX2 CONFIGURATION AND SYSTEM INTEGRATION GUIDE
19 Section 1 Intro and Overview
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 GalaxyNASLX2 chassis’ in the top of the
rack.
A brief overview of GalaxyNASLX2 installation follows:
1. Select an appropriate site for the rack.
