SC200 and SC220 Overview
A Storage Center enclosure holds the physical disks that provide storage. The interface
between the controller IO cards and the enclosure is refe rr ed to as back-end con nectivity.
SC200 and SC220 Hardware
The Storage Center SC200 and SC220 are 2U size SAS enclosures. The SC200 en closure
supports up to 12 3.5-inch hard drives installed in a four-column, three- row configuration.
The SC220 enclosure supports up to 24 2.5-inch hard drives installed vertically side-byside. The SC200 and SC220 enclosures ship with two power supply/cooling fan modules
and two redundant enclosure management modules (E MMs).
SC200 and SC220 Monitoring and Diagnostics
The Storage Center OS generates alert messages for temperature, IO module, fan, disk,
and power conditions for Storage Center components. Use the Storage Center System
Manager to view these alerts.
The SC200 and SC220 enclosures also have LED indicators to notify you of a possible
problem with the enclosure.
Note: Dell OpenManage Server Administrator is not available for SC200 and
SC220 enclosures.

Safety Precautions
Always follow these safety precautions to avoid injury and damage to the enclosure.
Electrical Safety Precautions
Always follow electrical safety precautions to avoid injury and damage to the enclosure.
Warning: Disconnect power from the enclosure when removing or installing
components that are not hot-swappable. When disconnecting power, first power
down the controller(s) and enclosure(s) using the S tor age Center System Manage r
and then unplug the power cords from all the power supply/cooling fan modules in
the enclosure.
• Know the locations of the e quipment power switches and the room's emergency poweroff switch, disconnection switch, or electrical outlet.
• Do not work alone when working with hi gh voltage components.
• Do not use mats designed to decrease electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed as
electrical insulators.
