Note: Before beginning the rack installation of your library, read the information
on Rack Safety in the Safety and Environmental Notices chapter. Also, verify
that no foot pads are installed on the bottom of your library. If foot pads are
installed, perform "Removing Library Foot Pads" on page 12-28, then return
here.
Important: Because of the weight of a multi-module library, it is strongly
recommended that you install it in the lowest position in a rack. Without
drive sleds and power supplies, a control module weighs approximately 50
18-32 kg (39.7-70.5 lbs)
lbs. Without drive sleds and power supplies, each expansion module
weighs approximately 65 lbs.
The following table gives the amount of rack space required for each library,
measured in Electronics Industry Association Units (EIA units or U). One EIA is
equal to 4.45 cm (1.75 inches).
An industry-standard rack will have 3 mounting holes for each EIA increment (see
Figure 3-14 on page 3-16.
