Installing a 2104 Model DU3

Important

The installation of this product is a customer responsibility.

Attention:

Before continuing with any of the actions described in this book, please refer to Appendix B, “Translated Safety Notices”, on page 63.

These instructions describe how to:

vInstall a 2104 Model DU3 into an RS/6000™ or IBM™ ERserver pSeries rack (system rack or expansion rack)

vConnect the 2104 Model DU3 to a power source

vConnect the 2104 Model DU3 to the using system

vSwitch on and test the installation

The instructions assume that:

vThe rack has already been set up

vA stabilizer has been correctly attached to the bottom front of the rack to prevent the rack from tipping forward while the 2104 Model DU3 is being installed into the rack. (If necessary, see the Installation and Service Guide, or equivalent, for the rack.)

vYou have access to:

–Preinstallation planning information for the system

–2104 configuration information

If the 2104 Model DU3 has already been installed in the rack:

vGo to “Connecting the 2104 Model DU3 to the Power Source” on page 29 if the power cables for the 2104 have not been installed.

vGo to “Connecting the 2104 to the Using System” on page 31 if the power cables for the 2104 have been installed.

Notes:

1.Each rack-mounted 2104 requires an airflow of 1.1 m³ per minute (40 ft³ per minute). When racks containing many 2104s are to be installed together, the following requirements must be met to ensure that the 2104s are adequately cooled:

vThe airflow enters at the front of the rack and leaves at the back. To prevent the air that is leaving the rack from entering the intake of another piece of equipment, racks should be positioned in alternate rows, back-to-back and front-to-front.

vThe front of racks should be positioned on floor-tile seams, with a full line of perforated tiles immediately in front of the racks. Each perforated tile should have an air flow of at least 11.34 m³ per minute (400 ft³ per minute). The underfloor temperature must not exceed 15°C (60°F).

vWhere racks are in rows front-to-front or back-to-back, there should be a gap of at least 1220 mm (48 in) separating the rows.

vTo ensure correct air flow within each rack, the rack filler plates must be installed in unused positions. Also, all the gaps in the front of the racks must be sealed, including the gaps between the 2104s.
