Installation and Configuration
WARNING: Before performing the following procedure, review the safety
instructions that came with all Storage Center components.
WARNING: Battery pack MUST be removed before the controller is
removed from the enclosure.
WARNING: Installing an incompatible battery on the server board may
increase the risk of fire or explosion. Observe the following precautions:
• The battery should only be replaced with a battery that is the same or
equivalent as the factory installed battery.
• Do not attempt to open or service the battery. Do not dispose of the
battery in a fire or with household waste. Contact the local waste
disposal agency for the location of the nearest battery deposit site.
Laser Safety statement
The unit is certified in the U.S. to conform to the requirements of DHHS
21 CFR, chapter 1 Subchapter J for Class I (1) laser products, and
elsewhere is certified as a Class I laser product conforming to the
requirements of IEC 60825-1:2007.
Class I laser products are not considered to be hazardous. The laser
system and unit are designed so there is never any human access to
laser radiation above a Class I level during normal operation, user
maintenance or prescribed service condition.
Unpacking the System
NOTE: Unpacking, installing, and deploying your Storage Center may be
done only by a certified service technician.
CAUTION: Class I laser radiation when open, avoid
exposure to the beam.
DANGER: Laser radiation, avoid direct exposure to beam.

2 Getting Started With Your System
Before you begin, make sure the site where you intend to set up and use
the Storage Center has the following:
• Standard power from an independent source or a rack power
distribution unit with a UPS.
• Storage Center with the latest firmware, BIOS, and drivers. Contact
your supplier for the correct software versions.
Installation Overview
The installation process follows the general steps below. For detailed
information, refer to vendor documentation supplied with the equipment.
NOTE: The system is intended for restricted access location in
accordance with the National Electric Code, National Standards Institute
(ANSI/National Fire Protection Association (NFPA) 70).
CAUTION: If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater
than room ambient temperature. Therefore, consideration should be given
to installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer. For more
information, see "Technical Specifications" on page 7.
1 Assemble the rails following the safety instructions and the rack
installation instructions provided with your system.
2 Install network switches, as applicable.
3 Install the SC4020 chassis into the rack.
• Always load the rack from the bottom up for weight stability.

Getting Started With Your System 3
• You can allow room for expansion if you have fewer than the
maximum number of enclosures.
4 Unwrap and insert each drive into the enclosure one at a time.
• Protect the drive from static discharge.
• Handle drives by the edges of the frame.
CAUTION: If the enclosure system operates for more than a few minutes
with missing drives, the enclosure can overheat, causing power failure and
data loss. Such use may invalidate the warranty.

4 Getting Started With Your System
Connecting the Power Cables
1 Ensure that the power switch is in the OFF position before connecting
the power cables.
2 Connect the enclosure power cables to the rack power.
Securing the Power Cables
1 Secure the cables firmly to the bracket using the strap provided.
2 Plug the other end of the power cables into a grounded electrical
outlet or a separate power source such as an uninterrupted power
supply (UPS) or a power distribution unit (PDU).
