  • Page 8: Introduction

    1 Introduction The Exos E 4U106 storage enclosure product is a high-capacity expansion enclosure designed for cloud and enterprise environments, using ADAPT software features. It supports high-demand storage applications that require high data availability, capacity, and performance. Each storage enclosure can be used either as a server-attached Just a Bunch of Disks (JBOD), or cabled to a RAID bunch of disks (RBOD) as an Expanded Bunch of Disks (EBOD) for added storage.

  • Page 9: System Overview

    2 System overview The Exos 4U106 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 disk drives, you must populate from front to back, filling an entire lateral bay before populating the next bay.

  • Page 11: Storage Enclosure Pcbas

    The storage enclosure provides separate access to two bays:  the main bay and the auxiliary bay. The PCBAs identified in this section are all assemblies that require replacement by Seagate-authorized warranty and repair personnel, other than the SAS expander modules.

Heed all warnings and cautions on labeling and throughout this guide to reduce risk of personal injury or damage to equipment.

  • Page 14: Complete Installation Prerequisites

    To adhere to installation safety precautions: Site preparation 1. Use the installation checklist. 2. Clear the site for installation and secure a static-protected area. Before storage enclosure installation 1. Unpack the storage enclosure in a clear area, using appropriate safety precautions. 2.

  • Page 15: Unpack And Prepare The Storage Enclosure

    CAUTION The storage enclosure ships in a partially-populated state. All PCBAs and FRUs ship in the storage enclosure, but the disk drives do not. It is very heavy, so handle with care and adhere to Seagate recommendations. There are two primary packing configurations: a three-piece or a regular slotted container. Neither configuration includes the drive modules, which ship separately, based on system configuration: Single drive modules, 10-packs, or 24-packs.

  • Page 16: Figure 4 Default Belt Straps Already Around The Storage Enclosure

    To unpack the enclosure: 1. Prepare the site for the storage enclosure installation. This includes meeting all product specifications and providing a clean, clear, static-protected environment prior to unpacking the storage enclosure. 2. Examine packaging for damage. This includes cuts, water damage, or evidence of mishandling during shipment. 3.
