Dell SC5020, SC5020F Manual

Notes, Cautions, and Warnings
NOTE: A NOTE indicates important information that helps you make better use of your product.

A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.

A WARNING indicates a potential for property damage, personal injury, or death.

Setting Up the Storage System

Consider the following best practices when setting up an SC5020 series 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.

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

Two person lift required

A fully configured SC5020 series storage system weighs approximately 43 kg (95 lb). Use appropriate lifting methods when installing the storage system.

Laser Radiation for Fibre Channel Storage Systems


Class I laser radiation when open, avoid exposure to beam.

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 might 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:

• SC5020 and SC5020F Storage Systems Owner's Manual
  Provides information about an SC5020 series storage system, such as hardware features, replacing hardware components, and technical specifications.
• Dell Storage Manager Administrator's Guide
  Provides instructions for using the Dell Storage Manager software.
• Unisphere and Unisphere Central for SC Series Administrator's Guide
  Provides instructions and information for managing storage systems using Unisphere and Unisphere Central for SC Series.

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 a 3U space in the lower 20U of the rack to install the storage system. If you plan to install the storage system above the lower 20U of a rack, a customerprovided mechanical lift must be used to avoid injury.

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.

About this task
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 SC5020 series 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: Dell recommends using two people to install the rails, one at the front of the rack and one at the back.

Steps

1. Position the left and right rail end pieces labeled FRONT facing inward.
2. Align each end piece with the top and bottom holes of the appropriate U space.
   
   Figure 2. Attach the Rails to the Rack
3. Engage the back end of the rail until it fully seats and the latch locks into place.
4. Engage the front end of the rail until it fully seats and the latch locks into place.
5. Align the system with the rails and slide the storage system into the rack.
   
   Figure 3. Slide the Storage System Onto the Rails
6. Lift the latches on each side of the front panel and tighten the screws to the rack.
   
   Figure 4. Tighten the Screws

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.

Install the Front Bezel

Install the bezel on the front of the storage system.

Steps

1. Hook the right end of the bezel onto the storage system.
   
   Figure 5. Front Bezel
2. Insert the left end of the bezel into the securing slot until the release latch snaps into place.
3. Secure the bezel with the keylock.

Next step
Install the expansion enclosures in the rack. See the instructions included with the expansion enclosure or in the expansion enclosure Service Guide 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. Use the straps to secure the power cables to the storage system chassis.
   
   Figure 7. Secure the Power Cables
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).
