9176/D173 D
ISK SUBSYSTEM - SITE PREPARATION GUIDE 15
S
IXTH EDITION
StorageTek™ 9170 Disk Array and D173 Disk Controller Array
Weight
Ensure that the site’s floor can support the total weight of all drive trays and associated
equipment. The 9170/D173’s weight depends on the number of drive modules installed in
the tray. Table 6 lists the unit and shipping weights for individual modules and for the
following drive tray configurations:
NOTE A maximum configuration means the weight of a drive tray containing 10 drive
modules, two channel/controller modules, two fan modules, and two power
supply modules, and one address card module (9170 only). A minimum
configuration only has four drive modules, and an empty chassis has all FRUs
and motherboard removed.
If you have the original steel chassis, just add 9.5 kg (21 lbs) to the weights shown above.
New orders will be shipped with the new aluminum chassis. The total weight of the Disk
Subsystem depends on the number of 9176 Disk Controllers, D173 Disk Controller
Arrays, and 9170 Disk Arrays in the cabinet. A typical StorageTek 9176 Disk Subsystem
may weigh approximately 227 kg (500 lbs) or may weigh as much as 550 kg (1200 lbs).
Refer to the M03 Rackmount Cabinet User’s Guides for more information. These manuals
are online at gandalf.stortek.com/ctp/9176/index.html.
