Safety notices
This guide covers the Nexsan E32X/Nexsan E18X Storage SystemsStorage Expansions only. Refer to the
relevant product manuals for information on other Nexsan Storage Systems or Storage Expansions and
other Nexsan products mentioned in this guide.
Always observe the following precautions to reduce the risk of injury and equipment damage:
WARNING: There is a risk of ELECTRIC SHOCK if Nexsan E-Series components are removed or
tampered with when a Nexsan Storage System power is on. Only a trained operator may remove
certain FRUs. The Nexsan E-Series Storage Systems include the following FRUs:
Power Supply modules
RAID Controller and Expansion modules
Disk drives
Fan modules
The storage system should only be installed in a clean, dry environment. The operating temperature is 5º
to 30º C (41º to 86º F), with operating relative humidity at 20 to 80%, non-condensing.

vi Part Number: P0450137, Rev. B
www.nexsan.com
Nexsan BEAST™ and E-Series™

The cordset specification for the Nexsan E32X/Nexsan E18X in North America is USA IEC C13 to IEC
C14, rated 125V/15A. When applying power to the storage system, use ONLY the IEC power cords
originally supplied with it. Do NOT use other power cords, even if they appear identical to the supplied
cords.
Only a fully-trained Service Engineer is authorized to disassemble any other part of the storage system,
and then only when the storage system is powered off.
All Nexsan E-Series Storage Systems have multiple power connections; as a result, you must remove all
power leads to completely remove power from the storage system.

3. Power LED(PWR) Indicates the status of power to the components in the drawer.
Green indicates that all power levels are within specifications. Red
indicates that one or more power levels are outside of
specifications. The Environmental Information page (under
System Information) in the graphical user interface (GUI) displays
details (see the Nexsan High-Density Storage User Guide).
If the PWR LED on the left drive drawer is amber and all other front
panel LEDs are off, this means that the Nexsan Storage System
has been powered down through the GUI. It can be powered back
up using the SW0 switch (see Rear panel on the next page).
4. Disk LED (DSK) Indicates the status of the disk drives in the drawer. Green indic-
ates that all disk drives are operating within specifications. Red
indicates that one or more disk faults have been detected. The

interface (GUI) displays details (see the Nexsan High-Density Stor-
age User Guide).
5. Environment LED
(ENV)
Indicates the temperature and fan status for the drawer. Green
indicates that the drawer temperature is within specifications and
that all fans are operating properly. Red indicates that the
temperature exceeds specifications or that one or more fans are
not operating properly. The Environmental Information page
(under System Information) in the graphical user interface (GUI)
displays details (see the Nexsan High-Density Storage User
Guide).
6. Status LED (STAT) Indicates overall status. Green indicates that the Nexsan Storage
System is operating within specification. Amber indicates that the
drawer is unlocked. Red indicates a fault in the drawer.
If all STAT LEDs are red, this indicates that there is an issue with
the Nexsan Storage System that is not drawer-specific. The
Environmental Information page (under System Information) in
the graphical user interface) displays details (see the Nexsan
High-Density Storage User Guide).

Chapter 2:Adding Modules
Nexsan E18X and Nexsan E32X Storage Expansions are designed so that adding data disks can be
performed while the system is powered on and operating normally.
CAUTION: Computer components and disk drives are sensitive to electrostatic discharge (ESD).
Always ground any electrostatic charge from your person before touching components with your
hands or with any tools. Always use an anti-static wrist strap (one ships with each Nexsan Storage
System) while installing or performing maintenance on any Nexsan Storage System. See Take
proper ESDprecautions on the next page for detailed instructions.

Take proper ESDprecautions
CAUTION: Computer components and disk drives are sensitive to electrostatic discharge (ESD).
Always ground any electrostatic charge from your person before touching components with your
hands or with any tools. Always use an anti-static wrist strap (one ships with each storage system)
while installing or performing maintenance on any Nexsan Storage System.
►To protect the storage system from electrostatic discharge:
1. Ground any electrostatic charge from your person by touching a metal part of the rack or any properly
grounded conductive object (such as the ground point at an anti-static workstation).
2. Attach the clip end of the anti-static wrist strap to the rack’s ESD grounding pin or to any bare metal part
of the rack (for a racked storage system) or to any proper grounding point (for an unracked storage
system). Secure the loop end around your wrist.
Figure 2-1: Attaching and putting on the anti-static wrist strap
CAUTION: Do not attach the anti-static wrist strap to any powder-coated part of the equipment
rack or storage system. The powder coating can interfere with the transmission of current,
resulting in improper grounding which can allow a static charge to build.
3. When working on unracked storage systems or components, place the storage system or component
on an anti-static surface.

Adding disk drives
CAUTION: Computer components and disk drives are sensitive to electrostatic discharge (ESD).
Always ground any electrostatic charge from your person before touching components with your
hands or with any tools. Always use an anti-static wrist strap (one ships with each Nexsan Storage
System) while installing or performing maintenance on any Nexsan Storage System. See Take
proper ESDprecautions on the previous page for detailed instructions.
Systems that are not fully populated with disk drives can have disk drives added to them at a later time.
Note The Spare Mode that the Nexsan Storage System is set to determines whether or not newly-inserted
disks are automatically assigned as pool spares. To check or set the spare mode, go to Configure RAID >
Spare Mode in the graphical user interface (GUI). See the Nexsan High-Density Storage User Guide for
more information.
►To add disk drives to the Nexsan Storage Expansion:
1. Turn the drawer lock clockwise to unlock the drive drawer.
Figure 2-2: Unlocking the drive drawer
The STATLEDturns amber to let you know that the drive drawer is unlocked.
CAUTION: Only open ONE drawer at a time. Fully close and lock each drawer before opening
another one. Failure to do so may overbalance the rack, causing equipment damage or injury
to personnel.
2. Carefully slide the drawer all the way out until the side rail locking tab clicks into place.
Figure 2-3: Sliding the drive drawer out
CAUTION: Do not lean on or place any heavy object on an open drive drawer. Doing so may
damage the drawer slide mechanism or overbalance the rack.

CAUTION: Disk drives are shock sensitive. Perform all actions involving disk drives carefully
to avoid damage and data loss.
3. Using the drive guides to help you orient the disks, carefully load the new disk drive into a drive slot.
Make sure that each disk is fully seated and that the drive ejection handles are flat against each drive.
Figure 2-4: Loading a new disk drive (Nexsan E18X top; Nexsan E32X bottom)
The drive status LED lights up green to inform you that the disk is connected and functioning properly.
CAUTION: For Nexsan E32X Storage Systems, if the drive drawer contains fewer than 16
drives, the slots without drives MUST have blank drive carriers in them in order to maintain
optimal drive and Nexsan Storage System cooling efficiency.
CAUTION: For Nexsan E18X Storage Expansions, where possible, always load disk drives in
stacks of three. Leaving large gaps between disk drives decreases cooling efficiency and may
result in some disk drives overheating.
