Introduction
System configuration
5
Install in racks that meet the following conditions.
≥
Use a standard 19-inch rack that conforms to EIA standards.
≥
A rack with a depth of at least 1000 mm (39.4
q
) is recommended.
≥
Use a server rack (must have front and rear panel mount
frames and square mounting holes).
≥
Use a rack with panel mount frames with universal spacing mounting holes.
≥
Use a rack with panel mount frames whose mounting holes
are of
∏
9.3 mm (0.4
q
) or more.
≥
Use a rack with panel mount frames with a flatness within
0.5 mm (0.02
q
) at the front of the rack so that connections
between apparatuses can be maintained.
≥
Use a rack with panel mount frames with mounting accuracy
(dimension D) of within ±2 mm (±0.1
q
) at the front of the rack so
that connections between apparatuses can be maintained.
≥
Use a rack with a height of at least 16U (Base Module (LB-
DH70A): 6U, Bottom Module (LB-DF81): 4U, Extension
Module (with the Writer Unit) (LB-DF72A): 6U).
≥
Use a rack with a weight bearing capacity that exceeds the
overall weight of the modules to be mounted. (Refer to the
"Cautions for regulations and safety" booklet included with the
modules for their weights. Refer to the operating instructions
for other devices to be mounted for information about them.)
≥
Install the panel mount frames so that the ones on the front
and rear sides are 660 mm (26.0
q
) to 790 mm (31.1
q
) apart.
≥
Install the drawer-side’s panel mount frames so that the
distance between an imaginary line formed by these frames
and an imaginary line extending horizontally from the
projection on the inner surface of the rack’s drawer-side
door will be 55 mm (2.2
q
) to 115 mm (4.5
q
). (The frames can
be adjusted in 3 steps at 20 mm (0.8
q
) intervals)
≥
Magazine drawers can jump out up to a maximum of 90 mm
(3.5
q
) when they open. Depending on the specifications of
the rack, it may not be possible for the door to be opened
when this happens, so this should be checked.
