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, redundant cooling, 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 describes the major hardware features of the system and identifies front- and back-panel components and LED
indicators.
