IBM 2104 Model DU3 - Manual (Page 17)

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:
v Install a 2104 Model DU3 into an RS/6000 ™ or IBM ™ ERserver pSeries rack
(system rack or expansion rack)
v Connect the 2104 Model DU3 to a power source
v Connect the 2104 Model DU3 to the using system
v Switch on and test the installation
The instructions assume that:
v The rack has already been set up
v A 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.)
v You have access to:
– Preinstallation planning information for the system
– 2104 configuration information
If the 2104 Model DU3 has already been installed in the rack:
v Go to “Connecting the 2104 Model DU3 to the Power Source” on page 29 if the
power cables for the 2104 have not been installed.
v Go 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:
v The 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.
v The 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).
v Where 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.
v To 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.
