  • Page 9: System Overview

    2 System overview The Exos CORVAULT storage enclosure mounts to a rack cabinet, occupying four EIA rack space units (4U) and contains up to 106 hot-swappable drive modules. CAUTION Make sure you are not connected to power at any time during installation procedures. CAUTION Only operate the storage enclosure in a dust-free environment to meet temperature control and airflow requirements.

  • Page 10: Storage Enclosure Modules

    Figure 1 Storage enclosure with rails Storage enclosure modules The storage enclosure contains a number of field-replaceable units (FRUs). Modules or components that require Seagate- authorized warranty and repair personnel to replace them are not identified. CAUTION If you partially populate the storage enclosure with drive modules, you must populate from front to back, filling an entire lateral bay before populating the next bay.
