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 described in Installing the support rails and Installing a Storwize V7000 Gen2 for Lenovo and Storwize V7000 Gen2+Lenovo Storage V series control enclosure. 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:
  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.
  2. For more information about configuration guidelines and restrictions, see the following website:
  3. If a Lenovo Storage V series system is clustered with a Lenovo Storage V series system, NEBS compliance cannot be enabled. NEBS compliance is not supported on Lenovo Storage V series systems.
