Dell™ PowerVault™ 220S and 221S systems are reliable, flexible, external SCSI expansion enclosures designed to support

multiple Dell storage environments and RAID configurations. Each system offers maximized drive-spindle count, hot-plug hard

drives, optional redundant power supplies, redundant cooling modules, rackmount capability, systems management features,

and a modular design for easy upgrades. Most major components, including hard drives and power supply/cooling modules

are hot-pluggable and can be removed and replaced easily. The enclosure management module (EMM), split-bus module, and

SCSI terminator card are "warm-pluggable." This means they can be removed or inserted while the power is on, but all I/O

activity has ceased. This section identifies front- and back-panel components and LED indicators. For more information on

system features and specifications, see your User's Guide.
