Chapter 3. Installation
This chapter discusses how to plan and install your IBM COS small disk enclosure into an industry
standard 19 inch rack cabinet.

Installation planning
You must be familiar with the configuration requirements of your IBM Cloud Object Storage Small Disk
Enclosure system before you start installation. See the previous section for the correct locations of each
of the plug-in modules.

Prepare for installing the small disk enclosure
The IBM COS Small Disk Enclosure is delivered with all drive carrier modules installed.
Warning: The enclosure together with all its component parts is too heavy for one person to easily
install into a rack cabinet.
CAUTION: Make sure that you wear an effective anti-static wrist or ankle strap and obey all
conventional ESD precautions when you touch modules and components. Do not touch midplane,
motherboard and module connectors, etc.
Before beginning the enclosure installation, familiarize yourself with the system configuration
requirements. The figures listed below show the locations for each plug-in module:
This section gives very important preparation requirements and good handling procedures. We encourage
you to use these procedures for a successful installation.
How to prepare the site and host server
Before you start, make sure that the site where you will install and use your IBM COS small storage
system has:
• A Standard AC power from an independent source or a rack power distribution unit with an UPS
(Universal Power Supply).
• IBM COS Controller node
