the enclosure maintain all system components below their
maximum temperature.

Prepare for Enclosure Installation
Note: 2U enclosures are delivered with all dummy drive carrier modules installed.
The enclosure together with all its component parts is too heavy for one person to easily install into a rack
cabinet.
CAUTION:
Make sure that you wear an effective anti-static wrist or ankle strap and obey all conventional ESD
precautions when you touch modules and components. Do not touch midplane, motherboard and
module connectors, etc.
This section gives important preparation requirements and good handling procedures. We encourage you to
use these procedures for a successful installation.

• A standard AC power supply from an independent source or a rack power distribution unit with an UPS
(uninterruptible power supply).
