Setting Up the Storage System
Consider the following best practices before setting up your SC7020 storage
system.
• Dell recommends that you use a dedicated SAN network for data
transmission when using a Fibre Channel or iSCSI storage system.
• Always configure redundant data paths to provide alternate paths to and
from the host server should one of the data paths become disabled.
• Before connecting any cables between the storage system and host server
or expansion enclosure, physically label each port and connector.
• Always follow proper power-up and power-down procedures when
cycling power across the network. Verify that critical network components
are on separate power circuits.
NOTE: This product is intended for restricted access locations, such as a
dedicated equipment room or equipment closet.
WARNING: 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.
Safety Warnings
Electrical disconnection
Indicates that all electrical supply connections to
the storage system must be disconnected before
proceeding.
The following information only applies to Fibre Channel storage systems.
Laser Radiation for Fibre Channel Storage Systems
CAUTION: Class I laser radiation when open, avoid
exposure to beam.
3

WARNING: Laser radiation, avoid direct exposure to
beam.
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.
Locating Your Service Tag
Your storage system is identified by a unique Service Tag and Express Service
Code.
The Service Tag and Express Service Code are found on the front of the
system by pulling out the information tag. Alternatively, the information may
be on a sticker on the back of the storage system chassis. This information is
used by Dell to route support calls to the appropriate personnel.
NOTE: The Quick Resource Locator (QRL) code on the information tag
is unique to your system. Scan the QRL to get immediate access to your
system information using your smart phone or tablet.
Other Information You May Need
To install the storage system, you may need the following additional
information.
NOTE: See the safety and regulatory information that shipped with your
Storage Center components. Warranty information is included as a
separate document.
• The Dell Storage Center SC7020 Storage System Deployment Guide
provides information about cabling storage controller hardware
components and configuring a new storage controller using the Storage
Manager Client.

Installation and Configuration
Before you begin installation, make sure that the site where you plan to install
the storage system has standard power from an independent source or a rack
power distribution unit with a UPS.
In addition, verify that there is space in the rack to install the storage system.
Unpacking Storage Center Equipment
Unpack the storage system and identify the items in your shipment.

Install the Storage System in a Rack
Install the storage system and other Storage Center system components in a
rack.
Mount the storage system and expansion enclosures in a manner that allows
for expansion in the rack and prevents the rack from becoming top‐heavy.

The SC7020 storage system ships with a ReadyRails II kit. The rails come in
two different styles: tool-less and tooled. Follow the detailed installation
instructions located in the rail kit box for your particular style of rails.
NOTE:
• The storage system and expansion enclosures each require 3U of
rack space for installation.
• Dell recommends using two people to install the rail, one at the front
of the rack and one at the back.

Follow this procedure to install the storage system in a rack.
1. Position the left and right rail end pieces labeled FRONT facing inward
and orient each end piece to seat in the holes on the front side of the
vertical rack flanges.
2. Align each end piece with the top and bottom holes of the desired U
space.
3. Engage the back end of the rail until it fully seats on the vertical rack
flange and the latch clicks into place.

4. Repeat these steps to position and seat the front end piece of the vertical
flange.
If the Storage Center system includes expansion enclosures, mount the
expansion enclosures in the rack. See the instructions included with the
expansion enclosure for detailed steps.
Connect the Power Cables
Connect power cables to the storage system.
1. Make sure that the power switches are in the OFF position before
connecting the power cables.
2. Connect the power cables securely to both power supply/cooling fan
modules in the storage system chassis.

Figure 6. Connect the Power Cables
3. Fasten the velcro strap to the power supply handle to prevent accidental
pulling of the power cable.
4. 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).
