Setting Up the Expansion Enclosure
Consider the following best practices before setting up an SC400 series expansion enclosure.
• Before connecting any cables between the expansion enclosure and storage system, 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) specied by the manufacturer.
Other Information You May Need
To install the expansion enclosure, you may need the following additional information:
•Dell Storage Center SC400, SC420, and SC420F Expansion Enclosure Owner’s Manual
Provides information about an SC400 series expansion enclosure, such as hardware features, replacing hardware components,
and technical specications.
•Dell Storage Manager Administrator’s Guide
Provides instructions for using the Data Collector Manager and the Dell Storage Manager Client.
Installation and Conguration
Before you begin the installation, make sure that the site where you plan to install the expansion enclosure has standard power from
an independent source or a rack power distribution unit with a UPS.
Unpacking Storage Center Equipment
Unpack the expansion enclosure and identify the items in your shipment.

Installing the Expansion Enclosure in a Rack
Install the 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 that were 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.
4. Mount the expansion enclosure chassis on the rails.
Figure 2. Mount the Expansion Enclosure Chassis in the Rack
5. Secure the expansion enclosure chassis to the rack using the mounting bolts.
For more information about installing the expansion enclosure, contact Dell Technical Support Services.
Install 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.
4

Connecting the Power Cables
Connect the power cables to the expansion enclosure.
1. Before connecting the power cables, make sure that the power switches on the expansion enclosure are in the OFF position.
2. Connect the power cables to the power supplies in the expansion enclosure chassis.
Figure 4. 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).
