About this guide

Introduction

This guide provides information about initial hardware installation and setup, as well as removal and installation of
customer-replaceable units (FRUs) for the Seagate Exos E 4U106 enclosure. The Exos E 4U106 is a high-capacity
expansion enclosure designed for use in cloud and enterprise environments. The Exos E 4U106 measures 4 Electronic
Industries Alliance (EIA) units of rack height (7") and fits a 1.2 m rack. It conforms to Common Form Factor (CFF) for
canister bay support, and it integrates with Seagate controller enclosures for storage management. The integral cable
management arm (CMA) allows the enclosure to be withdrawn from the rack for servicing, while remaining connected
and powered in this mode.

The Exos E 4U106 is designed for use as an expansion enclosure. This 4U106 enclosure can either be used as a
server-attached Just a Bunch of Disks (JBOD), or it can be cabled to an RBOD (RAID Bunch of Disks) as an Expanded
Bunch Of Disks (EBOD) for adding storage.

Intended audience
