Unique Situations
Customer Cabinets In the event that you are installing into existing customer
cabinets, make sure that they are 19 in. (482.6 mm) rackmount cabinets that conform to
EIA-310-D. Also ensure that mounting rails accommodate a minimum internal width of
45 cm (17.72 in.) and a depth of at least 51.5 cm (20.3 in.). At this minimum depth, you
need unobstructed rear cabinet access for the removal of FRUs (otherwise you will have to
remove the 9176 controller or 9170 disk array to allow room to remove FRUs from the
back of the units). Ideally, it is more practical to have at least 66 cm (26 in.) of depth to
allow adequate space to remove FRUs.
NOTE StorageTek’s adjustable mounting rails require 450 mm (17.72 in.) width
between front-facing vertical mounting flanges. Also the depth from the front to
the back mounting flange must be between 660 mm (26 in) to 787 mm (31 in).
Most cabinets have their own custom mounting rails, which may be used, provided they
have enough shelf support to accommodate weight, device widths from 445 mm to 450
mm (17.5 to 17.7 inches), and depths of at least 660 mm (26 in.) without obstructions.
Floor and Ceiling Mounting In some customer sites, the cabinet may be required to
be secured to the floor. The M03 rackmount cabinets has a total of eight weld-nuts
underneath the baseplate. You may use 1/2-13 bolts to secure a mounting bracket to the
baseplate. At least four holes are available to secure the cabinet to the floor, and two holes
are available to secure to the ceiling. Refer to the M03 Rackmount Cabinet User’s Guide
for hole locations and more information about this feature.
