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.

4

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).
