Preparing The Rack Enclosure - IBM xSeries 240 81Y Hardware Maintenance Manual

Before you begin
Before you begin to install the server in the rack,
review the safety and handling guidelines
specified under "Safety information" on
page 224.
To ensure rack stability, plan the installation of
servers in the rack starting from the bottom. If
you are installing different server models in the
rack enclosure, install the heaviest models in the
lower part of the rack enclosure. For more
information, refer to the IBM Rack Configurator
program provided with the ServerGuide CDs.
Refer to ServerGuide information provided with
the server section of this Server Library.
Review the documentation that comes with the
rack enclosure for safety or cabling
considerations. Ensure that the planned
installation is within the rack's guidelines for heat
generation, electrical requirements, air flow, and
mechanical loading.
Verify that the rack can meet the operating
parameters, as detailed in "Specifications" on
page 52.
Turn off the server, if it is on.

management arm on the mounting rails of the rack
enclosure.

using the dots supplied with the template. Also
mark the holes for the chassis bracket cage
nuts.
