prevent accidental tipping of the rack causing damage or
personal injury.
AVERTISSEMENT: soyez prudent lors de l'installation ou
de l'enlèvement du support afin d'empêcher le
renversement accidentel de la crémaillère, pour éviter
dommages et blessures.
The rail kit included with the E2000 is adaptable for
installation in the two major types of hardware racks:
squared-holed and round-holed EIA-310 racks.
NOTE: A two-post telco-style rack or any rack that is less than
29-inches in depth will not support this appliance. Also, for
threaded-hole racks, Overland Storage recommends using a
shelf.
The rails are not universal. They are stamped LH (left)
and RH (right) and must be mounted on the appropriate
side (when facing the rack front).
Attach Inner Rails to Chassis
This procedure is required for all rack types:
1. Mark the screw holes on the rack where the rails will
be installed.
NOTE: Be sure rear holes are horizontally in line with the
front holes to ensure the unit remains level.
2. Remove the inner rail (Figure 2) from the rail set:

Install the Unit in the Rack
WARNING: It is recommended that a mechanical lifter (or
at least two people) be used during rack installation or
removal to prevent injury.
AVERTISSEMENT: pour éviter toute blessure il est
recommande qu'un monte-charge (ou deux personnes
au moins) soit utilisé lors de l'installation ou de l'enlèvement
du support.
1. At the front, extend the middle rail members until
they lock (click).
2. Confirm that the ball-bearing shuttles are at the
front (Figure 9).
Figure 9. Inserting Expansion Array Into Rack
3. Using a mechanical lifter or two people, insert the
appliance into the rack rails.
Lift the appliance to its install height and engage the
inner members on the appliance with the middle
members protruding from the rack, and slide the
appliance into the rack until it stops.
4. Slide the unit in and out a few times to ensure that
the expansion array does not bind.
If binding occurs, verify that the front and rear flanges
are mounted in the correct holes, readjusting the slide
positioning as necessary.
5. Using the two screws provided, secure the expansion
array flanges to the rack (Figure 10).

Disk Drives
The E2000 comes without disk drives (they are sold
separately in singles and 4-packs) and can be configured
as noted here:
Recommended Drive Configurations
(SnapServer S2000 and N2000 only)
Before installing or adding drives to an E2000 array that
is used with either an N2000 or an S2000, the following
must be observed:
•Different capacity drives can be installed in the same
expansion array. However, they should not be
included in the same RAID array, because capacity
usage for all drives in the RAID is limited to the
capacity of the smallest drive member.
•Drives of different rotational speed (such as, SAS and
SATA drives) can be installed in the same expansion
array
(Figure 11) , but they should not be installed in
the same column or be separated from each other by a
column of different rotational speed drives
(Figure 12
on page 4)
. If you are combining drives with different
rotational speeds, use the figures below to plan where
to place the disk drives.
•Overland recommends grouping columns of drives of
the same speed next to each other when possible.

Installing Drives
NOTE: Do not remove the disk drives from their carriers. Doing
so voids the drive warranty.
Once the unit is in the rack, install the drives. Initially,
the top row is empty and the other two rows are filled
with drive blanks. Remove as many blanks as needed:
1. If a drive blank is in the slot where you are about to
install a disk drive, remove the blank by pressing the
lever release button and pulling it out.
2. Remove a drive assembly from the packaging.
3. Press the button to release the lever.
4. With the button on the right, position the drive
assembly in front of the appropriate bay and slide it
in (Figure 13) until resistance is felt.
Figure 13. Inserting Drive Carriers
5. Push the lever in to lock the assembly in the bay.
6. Repeat Steps 1–5 for each remaining drive carriers.
IMPORTANT: To maintain proper airflow and cooling, a
drive assembly or a blank drive carrier must be installed
in every slot. No empty slots are allowed.
Attach the Bezel
Once the drives and blanks are installed, attach the front
bezel (Figure 14):
Figure 14. Attaching the Bezel
1. Insert the bezel tabs into the flange holes.
2. Push the other side in until it latches (clicks).
3. If desired, lock the bezel.
Cable Attachment
All cabling and power connections are located on the rear
panel of the E2000 expansion array (Figure 15). All
cooling exhaust is handled through the rear panel.
Figure 15. E2000 Rear Panel Connections
1. Plug the supplied SAS cable into the bottom SAS
Port (HOST) of the expansion array.
2. Plug the other end of the SAS cable into the SAS port
on the server or the top SAS Port (EXP) of another
existing E2000.
NOTE: If you are connecting additional E2000 arrays, the
SAS cable from a HOST port of the first array always
connects to the upper SAS Port (EXP) of the next array.
3. Attach the power cords to the AC Power sockets.
4. Plug the power cords into a UPS appliance or AC
power source.
Power Up the E2000
IMPORTANT: Always power up your E2000 expansion
arrays before powering up your head unit (if the head unit
is running, shut it down first). This enables the head unit to
discover all the attached expansion arrays.

To turn the expansion array ON, press and hold the
Power button (Figure 16) for no more than one (1) second.
Figure 16. Power Button on Left Flange
After you turn the power ON, the system performs a
self-test process, which takes about a minute. When all
expansion arrays are ON and running, power up the
SnapServer or REO appliance.
You must leave all the expansion arrays ON while you
complete any additional configuration processes for your
application and backup media servers.
Verifying that the E2000 is Online
1. Launch a Web browser and enter the Server name
(or IP address) of the SnapServer or REO 4600 to
which the E2000 is connected.
2. Depending on your server, use the instructions in the
following table to verify that your server recognizes
the E2000 expansion array.
Your E2000 appears in the GUI as a 12-disk drive
chassis. Disk drives installed in the E2000 appear as
online disk drives in the correct physical position.
Unpopulated drive slots appear as offline disk drives
(N2000 and S2000 only).
Additional Configuration
Because the SnapServer Expansion E2000 array works
with different Overland disk products, you need to refer
to the appropriate user guide that comes with your
SnapServer or REO system for any special configuration
steps, the total number of expansion arrays that can be
attached, and for instructions on creating RAID arrays
and drive pools.
