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 enclosures. You are now ready to begin installing the hardware components
and connecting the data cables and power cords.
NEBS compliant earth connection
When installing 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 V3700 enclosures, this connection is made via the front enclosure
mounting screws that are part of the standard installation described in “Installing
the support rails” and “Installing the enclosures” on page 24. To provide a reliable
electrical earth connection, the upright mounting rails of the racks into which
enclosures are installed must meet the following requirements prior to 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.
Note: If the Storwize V3700 system is required to be NEBS compliant, some
system configuration settings must be made. For details, see “Configuring a
Storwize V3700 system to be NEBS compliant” on page 62.
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.”
Procedure
To install the support rails, complete the following steps.
