Hardware
Dimensions
AS2000 shelves require a mounting surface that can support the
weight of the shelf and all associated plug–in modules. A 19–inch
(49 cm) or 23–inch (59 cm) equipment rack, cabinet, or desktop can
support the weight of Access System 2000 shelves. Multi-line,
Quint-line, and Dual-line shelves can be front or mid-mounted into
a 19– or 23–inch (49 to 58.5 cm) rack.
