*1 Clearance (a+b) is based on the floor load rating and the clearance (c). Floor load rating and
required clearances are shown in Table 19 (page 36).
*2 Clearance (d) is required over 300mm to open the front door. In the case that the clearance
(d) is less tan the clearance (a), give priority to clearance (a).

Notes:
1. Actual clearances for installation should be determined after consulting with construction specialist responsible
for installation building, as they could vary depending on the size/layout of the system and building conditions.
2. When various configurations of disk arrays are arranged in a row, clearance values based on the largest disk
array configuration should be used.
3. From the viewpoint of maintenance operations, it is suggested that Clearance (c) be made as large as possible.
