Chapter 1 Overview
How to Use This Guide
This guide provides information and assistance to system or network administrators
preparing for the installation of a SnapServer storage system on their network. Every
network topology is different, and every administrator works with different goals and
resources. Using this guide, administrators can determine what additional hardware
components or software packages to acquire before the server arrives.
Hardware Components
SnapServers come with the hardware required to install the server into an EIA-
compliant rack (if applicable), as well as the cables required to connect the server to a
power source and to an Ethernet network. Other hardware required for a basic
installation, such as Ethernet switches, racks, and UPS devices, must be supplied by
the administrator from third-party vendors.
Some advanced configurations involving expansion arrays or direct-attached tape
backup may require the separate purchase of SAS, SCSI, or FC-HBA cards from an
authorized Overland Storage reseller. The hardware checklists in this guide show the
required and optional hardware components available for each SnapServer model.
Software Components
SnapServers also come with native support for partner-vendor software packages that
enhance or extend the functionality and security of SnapServers. These packages
include antivirus, backup, and administrative software. SnapServers are also
compatible with a number of widely-used third-party backup solutions.
This guide briefly describes these software packages and provides information on
upgrade procedures. For full descriptions and specifications, see the SnapServer,
partner-vendor, or third-party vendor Web sites as appropriate.

Chapter 2 Hardware Components
All rack-mountable SnapServers and expansion arrays come with the cables and
hardware required to install them into a rack and connect them to the network or
other SnapServer storage products. Customers supply the rack, Ethernet switches,
UPS devices, and any backup devices such as a tape library.
The performance and functionality of the SnapServer can be enhanced through the
installation of additional hardware components. A SCSI card can be installed in the
SnapServer 410, 510, 620, and N2000 for attaching tape backup devices. Additional
RAM can also be installed to the SnapServer 510, 520, 550, 620, 650, and N2000. Your
SnapServer 520, 550, 620, 650. and N2000 capacities can be increased through the
attachment of one or more expansion arrays (SAS cards need to be installed in the 520
and 620 to allow for expansion). If your SnapServer N2000, SnapDisk E2000, or Snap
Expansion S50 came with less than the maximum number of drives, it can be
upgraded to increase available capacity. The number of Ethernet ports on the
SnapServer 520, 550, 620, and 650 can be increased to four with the installation of the
Ethernet PCI adapter. The SnapServer N2000 can increase the number of Ethernet
ports to six.
•Use only internal hardware components qualified by Overland Storage –
Overland Storage strongly recommends that you use only qualified components
from authorized Overland Storage resellers. Qualified means that Overland
Storage technicians have tested and verified that the component operates properly
with the SnapServer and other network components. Failure to use qualified
components may seriously impact data availability, could potentially lead to data
loss and corruption, and will void your warranty.
•Standardize on a single vendor for external hardware components – Not
only will standardization on a single vendor minimize the chance of unforeseen
interoperability failures, it will also simplify troubleshooting procedures.
Notes:
• For a complete list of qualified components, including replacement parts and
installation instructions, go to http://www.snapserver.com and navigate to your
server model
• To find an authorized reseller in your area, go to http://www.snapserver.com and
click the How to Buy tab.

SnapServer GuardianOS 6.5 Setup Guide Safety Precautions
Safety Precautions
•Environmental Conditions – Make sure the physical environment in which the
unit resides falls within the specifications for your model as described in this guide.
•Installing the Server or Expansion Array – During installation, make sure the
unit is always placed on a secure surface capable of supporting its weight.
•Connecting to the Main Power – Install the unit near an easily accessible power
source. Make sure the source is the proper voltage for your model. Place the power
cords out of the way of traffic; do not place any object over the power cords. If the
unit is taken offline for an extended period, disconnect it from the power source to
avoid possible damage from a power surge.
•Enclosure Openings – The openings in the enclosure ensure proper airflow and
prevent overheating; do not cover these openings. Never place liquids on or near the
unit to avoid spillage; liquid entering an enclosure opening could cause fire or
electrical shock.
•Cleaning the Unit – Before cleaning the unit, be sure to disconnect all cabling. Do
not use any liquid or spray cleaning agents to clean the unit; use only a damp sheet
or cloth.
•Servicing the Unit – If one of the following situations arises, do not attempt a
remedy:
• The power cord or plug is damaged.
• Liquid has penetrated the server.
• The unit has been exposed to moisture.
• The unit continues to operate in an unexpected manner even after suggested
solutions in the Administration Guide have been followed.
• The unit is dropped or otherwise physically damaged.
• The unit has obvious signs of damage.
If one or more of these situations exist, contact Overland Storage technical support.

Basic Hardware To Be Acquired from Third-Party Vendors
The hardware components listed in the following table are to be supplied by the
customer from third-party vendors.
Component Description
Ethernet Switches For optimal performance, use only switches that support GbE.
APC-Brand UPS
Devices
Overland Storage recommends that you use a UPS with SnapServers.
SnapServers are compatible with USB-based and network-based APC-
brand uninterruptible power supplies that allow you to take advantage of
the automatic shutdown capability. Visit the APC website for a listing of
optimal APC models for use with your SnapServer.
Rack for 1U Units
SnapServer 410
SnapServer 510
SnapServer 520
SnapServer 550
SnapServer 620
SnapServer 650
You can use either a two-post telco-style rack or a four-post rack to mount
the SnapServer 410. Non-EIA compliant racks may not be able to support
the server using only the front posts. If you are using a non-EIA rack,
Overland Storage recommends that you secure the server using slide
rails, available from an authorized Overland Storage reseller.
The SnapServer 410 comes with two L-shaped rack mount brackets
(ears). You can attach them in one of two ways: (1) to the front of the
server for mounting to the front posts of a four-post rack; or (2) to the
middle or front of the server for mounting to both posts of a Telco rack.
The SnapServer 510, 520, 550, 620, and 650 come with two (left and
right) slide rails and must be installed in a four-post, 32” deep (or greater)
EIA-compliant rack.
Note: Mounting the SnapServer 510, 520, 550, 620, or 650 into a two-
post rack is not supported.
Rack for 2U units
SnapServer N2000
SnapDisk E2000
Snap Expansion S50
The SnapServer N2000, E2000, and Snap Expansion S50 come with two
adjustable (left and right) slide rails for attaching the server to a 32” deep
(or greater) four-post EIA-compliant rack.
Note: Mounting the SnapServer N2000, E2000, or S50 into a two-post
rack is not supported.
The rails for the SnapServer N2000 and SnapDisk E2000 are designed
for square-hole racks. To use the units with round-hole racks, attach the
adapters included in the kit. The rack depth must be a minimum of 29
inches if you are using adapters. If you have adjusted your rack to under
29 inches, you will need to reset it before installing the N2000 or E2000.
For threaded-hole racks, Overland Storage suggests using a shelf.
