If the 2104 disk enclosure has already been installed in the rack:
v
Go to “Connecting the 2104 Model DL1 to the Power Source” on page 21 if the
power cables for the 2104 have not been installed.
v
Go to “Connecting the 2104 to the Using System” on page 23 if the power cables for
the 2104 have been installed.
Notes:
1. Each rack-mounted 2104 disk enclosure requires an airflow of 1.1 m
³
per minute
(40 ft
³
per minute). When racks containing many 2104 disk enclosures are to be
installed together, the following requirements must be met to ensure that the 2104
disk enclosures 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 m
³
per minute (400 ft
³
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 2104 disk enclosures.
2. The recommended operating temperature is 22°C (72°F) or lower.
