Prepare for installing the small disk enclosure

Edit online

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

How to unpack the small disk enclosure

  1. Examine the packaging for crushes, cuts, water damage or any other evidence of mishandling during transit. If you suspect that damage has happened, photograph the packaging before you open it: this is for possible future reference.
  2. The following figure shows the sequence for how to unpack.

How to plan and configure your installation

You should become familiar with the configuration requirements of your small disk enclosure system before you begin installation. Refer to the section on system configurations for more information.

Requirements for installation of the racks

You can install the small disk enclosure in an industry standard 19 inch cabinet that is capable of holding such enclosures.
  • Minimum depth: 707mm (27.83 inches) from rack posts to maximum extremity of enclosure (excludes rear cabling).
  • Weight: up to 29kg (64lb), dependent upon configuration, per enclosure.
  • There must be a minimum gap of 25mm (1 inch) clearance between the rack cover and front of drawer; and 50mm (2 inches) rear clearance between the rear of the drawer and rear of the rack. This is to make sure there is correct air flow around the enclosure.
  • The rack should cause a maximum back pressure of 5 pascals (0.5mm water gauge).
