Safety notices
This guide covers the Nexsan E60™/E60V™/E60VT™/E60P™ and Nexsan
E48™/E48V™/E48VT™/E48P™ digital storage units only. Refer to the relevant product manuals for
information on other Nexsan storage or expansion units 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 unit power is on. Only a trained operator may remove certain customer-
replaceable units (CRUs). The Nexsan E-Series™ storage units include the following CRUs:
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 unit 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 unit from the packaging, DO NOT lift the unit 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 unit
ONLY by the bottom edges of the chassis, using safe lifting practices.
The unit 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 unit in an enclosed cabinet or other small area without ventilation.
When installing the unit 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 unit
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™/E60V™/E60VT™/E60P™ and Nexsan
E48™/E48V™/E48VT™/E48P™ in North America is USA IEC C13 to IEC C14, rated 250V/10A. When
applying power to the unit, 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 unit, and then only
when the unit is powered off.
All Nexsan E-Series™ storage units have multiple power connections; as a result, you must remove all
power leads to completely remove power from the unit.
Nexsan E-Series™ storage units do not have power switches. Do NOT attach the power cords until the
unit is fully installed, with all disk drives in place.

Nexsan E60™/Nexsan E48™
Installation Guide

The Nexsan E60™/E60V™/E60VT™/E60P™ and Nexsan E48™/E48V™/E48VT™/E48P™ units are 4U,
rack-mountable RAID storage systems which can hold up to 48 or 60 SATA, SAS, or SSD data disks.
The base models of the Nexsan E60™ and Nexsan E48™ use 3Gb/s SAS for internal communication
between the RAID Controllers and hard disks. The V VT and P variants use 6Gb/s SAS for internal
communication. The VT variants also have a turbo card installed in each RAID Controller which optimizes
sequential writes in parity-based RAIDs. There is no upgrade path between the base models and either the V
or VT variants. It is possible to convert a V or VT variant to P specification.
Aside from the difference in internal communication speed and the presence of the turbo card in the VT units,
there is no operational difference between the base models and the V and VT variants. The P variant provides
more host ports and uses different serial and expansion connectors.
Note Unless otherwise specified, “Nexsan E60™/Nexsan E48™” is assumed to refer to all variants (base
model, V, and VT) of the Nexsan E60™ and Nexsan E48™ storage systems. Where information applies to
only one variant, that variant is specified.

Information) in the graphical user interface (GUI) has more information. See the Nexsan RAIDStorage
User Guide.
11. PSU fan LED: Indicates the status of the PSU fans. Green indicates that all fans are operating within
specifications. Red indicates that one or more fans are either running too slowly or have failed. When the
PSU is in standby mode, this LED is off. The Environmental Information page (under System
Information) in the graphical user interface (GUI) has more information. See the Nexsan RAIDStorage
User Guide.

12. Expansion port LEDs
For E60/E48/V/VT controllers:
There are two LEDs (L0 and L1), each indicating the connection status for an expansion port. Green
indicates that the SAS cable is properly connected. Flashing amber indicates that the cable is improperly
connected. If no cable is connected, this LED is off.
For E60P/E48P controllers:
Each connector has two LEDs below it. If neither is lit the port is disabled or disconnected. A green light
indicates that the connection is healthy, a flashing red light indicates an incorrectly attached cable, and a
flashing red light indicates that the connection may be faulty.
13. Management port LEDs (activity and speed): The left LED flashes green when there is port activity. The
right LED lights up green when there is a 100Mb/s connection. When there is only a 10Mb/s connection,
the right LED is off.
14. Controller status LED (STAT): Indicates the status of the RAID Controller.
For E60/E48/V/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 unit 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
below).
For E60P/E48P 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 Switches
below).
15. iSCSI port LEDs (activity and status): For 1Gb/s connections, the left LED illuminates green when the
power is connected, and both LEDs flash green when there is activity.
Switches
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 unit 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 RAID 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 RAID Storage User Guide). On dual-
controller systems, both SW0 switches must be held simultaneously for 8 seconds.
With the unit powered off:
Press and hold the SW0 switch on either RAID Controller for approximately 4 seconds to power up
the unit. Release the SW0 switch to boot normally.
Continue pressing the SW0 switch after the unit powers up to put the RAID Controllers into
Emergency mode (see the Nexsan RAID Storage User Guide). Emergency mode is indicated by the
controller status LED alternating between blue and red (see LEDs on page6).
Turbo cards (VT units only)
17. Turbo card LEDs: The LEDs on the turbo card indicate the status of the card. The LEDs are:
SP: Currently unused.
PAR: Indicates the status of the parity engine. Green indicates that the parity engine is active. If the
parity engine is inactive, this LED is off.
MEM: Indicates the status of the turbo card’s cache memory. Green indicates that data is in the
cache that needs to be written to disk. If there is no data in the cache, this LED is off.
STAT: Indicates the status of the turbo card. Green indicates that the card is operating normally.
Orange indicates that the card is initializing its cache memory. Red indicates a fault in the turbo card.
If the turbo card has been deactivated, this LED is off.
Host port options
Figure 1-5: Host port options
Fibre Channel 10gb Ethernet, Optical 10gb Ethernet, Copper SAS-to-Host
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.
Note Because of the presence of the turbo card (see Turbo cards (VT units only) above), Nexsan E60VT™
and Nexsan E48VT™ units can only have one HBA card installed.
1. Depending on the RAID Controller configuration, the host port connectors are one of the following:
Two Fibre Channel ports (0and 1) per HBAcard: 16Gb/s or 8Gb/s Fibre Channel optical SFPs.
Two 10Gb iSCSI (10GbE) ports (0and 1) per HBA card: 10Gb/s Ethernet optical SFPs or copper SFP
sockets for iSCSI.
Two SAS ports (0and 1) per HBA card: Mini-SAS 26 pin I-Pass (8088) connectors, each with four
6GB/s SAS links.
