Facility requirements
The facility where the SAN384B is in use must meet the following requirements to
provide for correct operation:
v Adequate supply circuit, line fusing, and wire size, as specified by the electrical
rating on the chassis nameplate
v An air flow of at least 425 cubic meters per hour (250 cubic feet per minute),
available in the immediate vicinity of the SAN384B
v The power specifications listed in Table 25 on page 124
v The environmental specifications listed in Table 24
v If the SAN384B will be installed in an EIA rack, ensure the following:
– All equipment installed in the rack has a reliable branch circuit ground
connection, and does not rely on a connection to a branch circuit, such as a
power strip.
– The rack is balanced and mechanically secured to provide stability in the
event of an earthquake.
– Additional equipment does not exceed the rack's weight limits.
Environmental requirements
Table 24 lists the environmental operating ranges for the SAN384B. The
requirements for non-operating conditions are also provided for acceptable storage
and transportation environments.
CAUTION:
For CA residents only: IBM recommends installing this product in a room size
of 2190 cubic feet (62 cubic meters) or larger at 0.4 ACH ventilation rate to
reduce the concentrations of any chemicals emitted by the product.
