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.
CAUTION: Load the rack from the bottom up to ensure rack stability. Empty the rack from the top
down.
Procedure
To install an enclosure, complete the following steps.
1. On either side of the drive assemblies, remove the enclosure end caps by grasping the handle and
pulling the bottom of the end cap free, then clearing the tab on the top of the enclosure.
