156 Installing the Disk Array FC60
Table 21 EIA Spacing for Racks and Array Enclosures
Note IMPORTANT: When installing an enclosure in a rack, if there is a space between
enclosures that space must be filled with a filler panel to maintain proper air
flow. This is a requirement for proper cooling.
When installing the array in the cabinet, install the enclosures from the bottom up (to
prevent the cabinet from becoming top heavy and avoid a potential tipping hazard). Refer
to the document supplied with the rack for proper installation information. Typically, disk
enclosures are installed from the bottom of the rack up, with the controller enclosure
installed directly above the disk enclosures.
Figure 54 shows EIA rack locations for installation of six disk enclosures and one
controller enclosure FC60 in a System/E rack. Special rails for the System/E racks allow
installation of enclosures at either full EIA or mid-EIA (1/2-EIA) position. This allows the
