Chapter 2. Installing the hardware
After verifying that you have all of the hardware components that you require,
you can install them.
You have completed the initial steps of verifying the shipping contents and
becoming familiar with the hardware components. You have verified that the
power and environmental requirements are met and have planned the location of
the enclosure. You are now ready to begin installing the hardware components and
connecting the data cables and power cords.
NEBS-compliant earth connection
When you install enclosures into a Network Equipment-Building System (NEBS)
compliant installation, each enclosure must have a reliable electrical earth
connection that is separate to any earth connections provided by power supply
cables.
On Storwize V3500 enclosures, this connection is made by using the front
enclosure mounting screws that are part of the standard installation described in
“Installing the support rails” and “Installing the enclosure” on page 14. To provide
a reliable electrical earth connection, the upright mounting rails of the racks into
which enclosures are installed must meet the following requirements before
installing the support rails and enclosures:
v Upright mounting rails must not be painted, oxidized or otherwise insulated
from the enclosure flanges and mounting rails. If paint, oxidization or other
insulation is present, it must be removed and the metal must be brought to a
bright, non-corroding finish.
v Upright mounting rails must have their own NEBS-compliant connection to
earth, independent of the earth connections provided by any power supply
cables.
Notes:
1. If the Storwize V3500 system is required to be NEBS-compliant, some system
configuration settings must be made. For details, see “Configuring a Storwize
V3500 system to be NEBS-compliant” on page 40.
2. For more information about Storwize V3500 configuration guidelines and
restrictions, see the following website: http://www-01.ibm.com/support/

Installing the support rails
Before installing an enclosure, you must first install support rails.
About this task
Note: For NEBS compliant installations, additional requirements are placed on the
rack into which the support rails and enclosures are to be installed. Before
proceeding, ensure that the rack meets the requirements listed in “NEBS-compliant
earth connection.”
