Position hands under the chassis to pull it free
from the foam insert. Do NOT lift out the US 316
chassis from its packaging using the controller
handles or attached rails.
B Place the components on an anti-static surface
until you are ready to use them.
US 316 Expansion package contents
One US 316 Expansion and front bezel
Rack-mounting hardware:
2 outer-rack rail assemblies (inner-chassis rails
are already installed)
4 mounting screws with 4 washers to attach
outer-rack rails to the rack
(1 on the front and 1 on the back for both the
left and right rail assemblies)
FASTier, SSD, and HDD drives. Check that the
components included in your shipment
correspond to your packing slip.
SAS cables (HD Mini SAS to HD Mini SAS)
Two power cords
1 electrostatic discharge (ESD) wrist strap
Rack the US 316 Expansion
CAUTION: Physical installation requires
two people.
Step 1: Remove the front bezel
A Turn the key lock at the right end of the bezel to
the unlock position.
B Unhook the left end of the bezel from the chassis.
Step 3: Install the inner rails on the chassis
(if necessary)
A Extend the inner rail toward the front of the rail
assembly as far as possible, then depress the
locking tab to pull it completely out.
B Place the inner rail on the side of the chassis
aligning the hooks of the chassis with the rail
extension holes.
C Slide the extension toward the front of the chassis.
D If desired, secure the chassis with screws.
E Repeat for the other inner rail.
Step 4: Install the US 316 on the rack
A Lift the US 316 chassis from each side—not from
the front and back.
B Line up the inner-chassis rails with the front of the
outer-rack rails.
C Slide the inner-chassis rails into the outer-rack
rails, keeping the pressure even on both sides;
you have to depress the locking tabs when
inserting.
Step 2: Install the outer-rack rails on the
rack
A Attach the RIGHT and LEFT outer-rack rails to the
rack by inserting the hooks included on the rails
into the holes provided on the rack.
The hooks should be located in the TOP holes of
the rack units selected.
B Extend rail assemblies to fit the depth of the rack.
Pull on the rear of the assembly until the hooks
reach the back of the rack.
C Screw the rail to the rack using the mounting
screws provided. The screws should be secured
in the BOTTOM hole on the front and back of
each rail assembly.
2 — US 316 Expansion Quick Start Guide
D Push the US 316 fully into the rack; you should
hear the locking tabs click into position.
E Tighten the thumbscrews that hold the front of the
US 316 to the rack.
Step 5: Install the data drives
CAUTION: Put on the ESD wrist strap
before starting:
A Slip the wrist loop over your hand (left or
right), then tighten the loop against your
wrist.
B Attach the clip end of the anti-static wrist
strap to a properly grounded metal
surface.
Installation order
A Install the FASTier SSDs in the slot as indicated
on the label on the drive.
B Install the disk drives in any order in the remaining
slots.
The half-populated drive configuration includes
empty drive carriers for expansion.
Page 3
To install the drives
A Slide the release
button on the front of
the drive carrier and
open the handle.
B Insert the drive carrier
into the drive bay until
the carrier contacts the
backplane.
C Close the drive carrier
handle to lock the
drive in place.
D Repeat these steps for each drive.
Connect the US 316 Expansion
Step 1: Connect the storage expansion to
the storage system
Connect from the add-on SAS OUT ports on each
storage system controller to the on-board SAS IN
ports on the storage expansion controllers, as
shown.
CAUTION: Do not connect to the Unity
Storage System from the on-board SAS
ports on either the Unity 4400 or the
Unity 6900.
Unity 4400 cascaded to US 316s
NOTE: The Unity Storage System is hot pluggable:
Once in service, powering down is not normally
required to add a Unity Storage Expansion. We
strongly recommend that you use an uninterruptible
power supply (UPS).
Power on the US 316 Expansion
The US 316 Expansion is hot-pluggable.
Step 1: Power on the US 316
A Press and hold the power button located on
the right front panel of the chassis until the power
LED lights up.
B Wait approximately 1 minute for the drives to all
become ready. All drive carrier activity LEDs
should be illuminated in green.
If a drive carrier activity LED does not light up,
check to make sure the corresponding drive is
properly seated in the chassis.
Step 2: Reattach the front bezel
If all LEDs indicate normal operational status,
reattach the front bezel to the US 316 Expansion:
A Hook the left end of the bezel onto the chassis.
B Fit the right side of the bezel onto the chassis.
C Turn the key lock at the right end of the bezel to
the lock position to secure the bezel to the chassis.
Step 2: Connect the power cables
A Plug the power cords into their respective power
supplies on the rear of the US 316 Expansion.
B Plug the power cords connected to the power
supply units into a high-quality strip that offers
protection from electrical noise and power surges.
Use only the power cords supplied with the
US 316 Expansion. Do not use another
type of cord or extension cords. For
additional power cords, please contact
Nexsan sales or reseller.
Monitor the US 316 Expansion
This section describes the front panel LEDs that help
you monitor the Nexsan US 316 Expansion.
Control panel LEDs
The two control panels located on the front left and
right sides of the US 316 Expansion have several
LEDs. These LEDs provide you with critical
information related to the corresponding node.
If the Fan fail LED or Power fail LED illuminates,
replace the component as described in the Nexsan
Unity Storage Expansion Reference Guide.
Drive carrier LEDs
Each drive carrier on the US 316 Expansion has two
LEDs. If a drive fails, replace the drive as described
in the Nexsan Unity Storage Expansion Reference
Guide at www.nexsan.com/ (see Support > Unity >
Documents & Downloads).
LED Indication
Power
Indicates power is being supplied to
the system’s power supply units. This
LED is illuminated when the system is
operating.
Heartbeat
This is a server board heartbeat LED
and indicates that power is being
supplied to the server board.

LED Indication
Safety notices
.
Drive
LED
Green
Red
NIC1
Indicates network activity on the LAN1
port when flashing.
NIC2
Indicates network activity on the LAN2
port when flashing.
Power fail
Indicates a power supply module has
failed. The second power supply
module takes the load and keeps the
system running, but the failed module
should be replaced as soon as
possible.
This LED should be off when the
system is operating normally.
Fan fail
When flashing, this LED indicates a
fan failure.
When lit continuously, this LED
indicates an overheat condition, which
may be caused by cables obstructing
the airflow in the system or the room
temperature being too high.
Check the routing of the cables and
make sure all fans are connected and
operating normally. You should also
check to make sure that the chassis
covers are installed.
Indication
A steady green LED indicates the drive is
powered on.
If this LED is not lit, the drive is not
getting power.
If this LED is flashing, the drive is being
accessed (read or write).
A steady red LED indicates a drive
failure.
This equipment must be installed and operated in
compliance with local laws and regulations.
Ensure that the ambient temperature at the
installation is between 5°C (41°F) and 30°C
(86°F). If the temperature at the site is not actively
regulated, ensure that daily and seasonal
temperature changes will not result in the ambient
temperature going outside these limits.
Always fully stabilize racks with wall anchors or
stabilizing legs, or both, before mounting the
Nexsan storage unit or any other components on
the rack.
Situate the rack so that full air flow at both the
front and the rear of the Nexsan storage unit is
possible.
Ensure that the floor beneath the mounting rack
has enough load-bearing capacity to support the
rack and all mounted components.
Always fully secure all rack-mounting hardware
when installing the Nexsan storage unit in a rack.
Insufficient rack-mount support may allow the unit
to fall onto other rack-mounted hardware or onto
the floor, potentially damaging equipment or
causing injury to nearby personnel.
