Chapter 2. Installing the system hardware
After verification that you have all of the hardware components that you require, you can install them.
You completed the initial steps of verifying the shipping contents and becoming familiar with the
hardware components. You verified that the power and environmental requirements are met and 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 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 system enclosures, this connection is made by using the front enclosure mounting screws that are
part of the standard installation that is described in “Installing support rails for 2U enclosures” on page
15 and “Installing enclosures” on page 19. 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:
• 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.
• 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 system is required to be NEBS-compliant, some system configuration settings must be made.
For details, see “Configuring a system to be NEBS-compliant” on page 135.
2. For the latest information about configuration guidelines and possible restrictions, go to the following
website; then, enter the product name and release in the search the field: http://www.ibm.com/

3. If a Storwize V5000 Gen2 system is clustered with a Storwize V5000 Gen 2 system, NEBS compliance
cannot be enabled. NEBS compliance is not supported on Storwize V5000 Gen 2 systems.
Installing support rails for 2U enclosures
Before you install a control enclosure or a 2U expansion enclosure in to the rack, you must first install the
support rails. The same rails for are used for the control enclosures and the 2U expansion enclosures.
About this task
Note: For NEBS compliant installations, more requirements are placed on the rack into which the support
rails and enclosures are to be installed. Before you proceed, ensure that the rack meets the requirements
that are listed in “NEBS-compliant earth connection” on page 15.
Procedure
To install the support rails for an enclosure, complete the following steps.
1. Locate the enclosure rails (Figure 11 on page 16).
The rail assembly consists of two rails that must be installed in the rack cabinet.
