The rear-door heat exchanger adds more weight to the rack. For information about
the weight of an empty and filled door, see “Rear-door heat exchanger” on page
15.
To ensure that all requirements are met, obtain the service of a qualified structural
engineer to prepare the floor.
Important: If you do not know or are not certain about the floor-load rating of the
installation site, you must check with the building engineer or another appropriate
person.
Rack dimensions and service clearance requirements
The installation site must accommodate the rack dimensions and minimum service
clearance for the FlashSystem A9000R system.
The IBM service representative must have enough space to open the front and rear
covers to service the FlashSystem A9000R system, including removing components
and other assemblies from the FlashSystem A9000R system.
Notes:
v You can position racks no closer than 45 cm (17.7 in.) to a wall.
v You can position racks alongside (next to) other racks.
v Because several rack designs are available from IBM and other vendors, space
between adjacent racks might be required to open the door for service. You must
determine the space requirement at the time of installation.
Table 6 and Figure 11 on page 23 describe dimensions and minimum service
clearance for the FlashSystem A9000R system.
