Before You Begin

Consider the following best practices before setting up your SC100/SC120 expansion enclosure.

• Before connecting any cables between the storage system and 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.

Other Information You May Need

Additional information you may need to install the expansion enclosure.

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 SCv2000/SCv2020 Storage System Deployment Guide provides information about cabling Storage Center hardware components and configuring a new Storage Center using the Dell Storage Client.

• The Dell Storage Center Dell Storage Client Administrator’s Guide describes how to use the Dell Storage Client to manage a Storage Center.

Installation and Configuration

Before you begin the installation, make sure that the site where you plan to install the expansion enclosure

Unpacking Storage Center Equipment

Unpack the expansion enclosure and identify the items in your shipment.

has standard power from an independent source or a rack power distribution unit with a UPS.

Installing the Expansion Enclosure in a Rack

Install the SC100/SC120 expansion enclosure in a rack.

NOTE: Mount the expansion enclosure in a manner that allows for expansion in the rack and prevents the rack from becoming top‐heavy.

1. Assemble the rails following the safety instructions and the rack installation instructions provided

with your expansion enclosure.

2. Determine where to mount the expansion enclosure in the rack and mark the location.

3. Install the rack rails at the marked location using the top mounting holes of the bottom U.

a. Insert the top locking pin in the middle mounting hole of the top U. b. Insert the bottom locking pin in the bottom mounting hole of the bottom U.

4. Mount the expansion enclosure chassis on the rails.

5. Secure the expansion enclosure chassis to the rack using the mounting bolts.

For more information about installing the expansion enclosure, see the Dell Storage Center SCv2000/SCv2020 Storage System Deployment Guide.

Installing the Front Bezel

Install the bezel on the front of the expansion enclosure.

1. Hook the right end of the bezel onto the expansion enclosure.

Figure 3. 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.

Cabling the Expansion Enclosure to a Storage System

Connect an SC100/SC120 expansion enclosure to the back-end SAS ports on an SCv2000/SCv2020 storage system

NOTE: In an SC100/SC120 expansion enclosure, the top storage controller is storage controller 1 and the bottom storage controller is storage controller 2.

1. If you are installing more than one expansion enclosure, cable the expansion enclosures in series by

connecting a SAS cable from the top EMM, port B of one expansion enclosure to the top EMM, port A of the next the expansion enclosures are connected together.

2. Connect a SAS cable from storage controller 1: port A to the first expansion enclosure in the SAS

chain: top EMM, port A.

3. Connect a SAS cable from storage controller 2: port B to the last expansion enclosure in the SAS

chain: top EMM, port B.

4. Connect a SAS cable from storage controller 1: port B to the last expansion enclosure in the SAS

chain: bottom EMM, port B.

5. Connect a SAS cable from storage controller 2: port A to the first expansion enclosure in the SAS

chain: bottom EMM, port A.

Connecting the Power Cables

Connect power cables to the expansion enclosure.

1. Make sure that the power switches on the expansion enclosure are in the OFF position before

connecting the power cables.

2. Connect the power cables to the power supplies in the expansion enclosure chassis.

Figure 5. Power Cables

3. Secure each power cable to the expansion enclosure chassis using the strain relief fasteners.

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).

Turning on the Expansion Enclosure

Turn on the SC100/SC120 expansion enclosure after racking and cabling all of the Storage Center components.

Turn on the expansion enclosure by pressing both power switches at the same time.
