Safety notices
This guide covers the Nexsan E60 and Nexsan E48 Storage Systemss 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
Computer components and disk drives are sensitive to static discharge. Take precautions to discharge
any electrostatic charge from your person before and while handling components with your hands or any
tools. Use an anti-static wrist-strap.
Ensure correct lifting methods are used when removing the storage system from its packaging and
positioning it into its required location. When lifting the system, two people at either end should lift slowly
with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.
When removing the storage system from the packaging, DO NOT lift the enclosure by any plastic parts
or module handles on the chassis. Doing so may cause damage to the chassis or to internal
components, or both. Lift the enclosure ONLY by the bottom edges of the chassis, using safe lifting
practices.
The storage system should only be installed in a clean, dry environment. The operating temperature is 5º
to 35º C (41º to 95º F), with operating relative humidity at 20 to 80%, non-condensing.
Do not install the storage system in an enclosed cabinet or other small area without ventilation.
When installing the storage system as a rack-mounted component, ensure that all Nexsan-supplied
mounting fixtures are secure. All bolts and screws should be fully tightened. Failure to comply with this
may result in the storage system not being fully supported in the rack and could lead to the product falling
from the rack, causing personal injury or damage to other rack components.
Ensure that the rack is sufficiently stable by having wall anchors and/or stabilizing legs, and that the floor
supporting the rack has sufficient strength for the overall weight loading.
The cordset specification for the Nexsan E60 and Nexsan E48 in North America is USA IEC C13 to IEC
C14, rated 250V/10A. 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.
Nexsan E-Series Storage Systems do not have power switches. Do NOT attach the power cords until
the storage system is fully installed, with all disk drives in place.

14. Controller status LED (STAT) Indicates the status of the RAID Controller.
For Nexsan E48V/VT and Nexsan E60V/VT
controllers:
Solid blue indicates that the controller is operating
within specifications and that there is no user data
in the cache.
Solid green indicates that the controller is
operating within specifications and that there is
user data in the cache, which will be retained in
flash memory upon power-down and then restored
when the Nexsan Storage System is powered up
again.
Flashing red (once per second) indicates that the
controller is offline due to a fault being detected.
Flashing green (twice per second) indicates that
the controller is operating in battery-backup mode
and is backing up cached data to flash memory.
This can take several minutes.
Alternating blue and red indicates that the
controller is booting in Emergency mode (see
Switches on the facing page).
For Nexsan E48P and Nexsan E60P controllers:
Solid green indicates that the controller is
operating within specifications.
Flashing red (once per second) indicates that the
controller is offline due to a fault being detected.
Solid red indicates that the controller has been
deliberately stopped.
Flashing green (twice per second) indicates that
the controller is operating in battery-backup mode
and is backing up cached data to flash memory.
This can take several minutes.
Alternating red and green indicates that the
controller is booting in Emergency mode (see

Table 1-12: Switches
Number Component Description
16. SW0 Switch This switch can be used to turn the RAID Controller off or on, boot the
controller in Emergency mode, or silence an audible alarm.
With the Nexsan Storage System powered on:
Briefly press the SW0 switch to silence the audible alarm. This can also
be done via the graphical user interface (GUI) (see the Nexsan Nexsan
High-Density Storage User Guide).
Press and hold the SW0 switch for approximately 8 seconds to power
down the RAID Controllers. If there is data in the cache, it will be stored
in flash memory. This is the same as performing a System Shutdown via
the graphical user interface (GUI) (see the Nexsan Nexsan High-
Density Storage User Guide). On dual-controller systems, both SW0
switches must be held simultaneously for 8 seconds.
With the Nexsan Storage System powered off:
Press and hold the SW0 switch on either RAID Controller for
approximately 4 seconds to power up the Nexsan Storage System.
Release the SW0 switch to boot normally.
Continue pressing the SW0 switch after the Nexsan Storage System
powers up to put the RAID Controllers into Emergency mode (see the
Nexsan Nexsan High-Density Storage User Guide). Emergency mode
is indicated by the controller status LED alternating between blue and
red (see LEDs on page14).

Host port options
The RAID Controllers can be configured (with one or two optional Host Bus Adapter (HBA) cards) for one of
four different host port options: 16Gb/s Fibre Channel, 8Gb/s Fibre Channel, 10Gb/s iSCSI (10GbE), or
SAS-to-Host.
Figure 1-13: Host port options
Fibre Channel 10gb Ethernet, Optical 10gb Ethernet, Copper SAS-to-Host
Depending on the RAID Controller configuration, the host port connectors are one of the following:
Host port type Description
Two or Four Fibre Channel ports (0and 1) per
HBAcard
16Gb/s or 8Gb/s Fibre Channel optical SFPs.
Two or Four 10Gb iSCSI (10GbE) ports (0and
1) per HBA card
10Gb/s Ethernet optical SFPs or copper SFP sockets
for iSCSI.
Two or Four SAS ports (0and 1) per HBA card Mini-SAS 26 pin I-Pass (8088) connectors, each with
four 6GB/s SAS links.
Depending on the RAID Controller configuration, the host port LEDs are one of the following:
Host port LED Description
16Gb/s Fibre
Channel port
LEDs (speed
and activity)
The top LEDis amber when there is a 4Gb/s connection and flashes amber when there
is activity. The middle LEDis green when there is an 8Gb/s connection and flashes
green when there is activity. The bottom LEDis amber when there is a 16Gb/s
connection and flashes amber when there is activity. All three LEDs light up during the
power-up sequence.
8Gb/s Fibre
Channel port
LEDs (speed
and activity)
The upper LED is orange when there is a 2Gb/s connection and green when there is a
4Gb/s connection. The lower LED flashes yellow for data activity, but also lights up
yellow when there is an 8Gb/s connection. When there is an 8Gb/s connection, the
upper LED is off. During the power-up sequence, both Fibre Channel port LEDs are solid
yellow. If both LEDs are flashing yellow, the Fibre Channel connection has been lost.
10Ge iSCSI
port LEDs
(connection
and activity)
For each 10Ge iSCSI connection (left and right), the lower LED lights up green when
there is a 10GbE connection and the upper LED flashes green when there is activity.
When there is no connection, these LEDs are off.
