JSA3800 Appliance Rack Requirements
The JSA3800 appliance can be installed in a four-post or two-post rack.
Table 9 on page 27 provides the details of requirements for rack size, clearance, airflow,
spacing of mounting brackets and flange holes, and connecting to the building structure.
Table 9: Rack Requirements for JSA3800
Specifications Rack Requirement
A 19 in. (48.3 cm) rack as defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310-D) published by the Electronics
Industry Association (http://www.eia.org). Size
• The outer edges of the mounting brackets extend the width of either
chassis to 19 in. (48.3 cm).
• The front of the chassis extends approximately 1.5 in. (3.81 cm) beyond
the mounting ears.
Clearance
• The holes within each rack set are spaced at 1-U [1.75 in. (4.5 cm)]. The
device can be mounted in any rack that provides holes or hole patterns
spaced at 1-U [1.75 in. (4.5 cm)] increments. The holes within each rack
set are spaced at 1-U [1.75 in. (4.5 cm)].
•
The device can be mounted in any rack that provides holes or hole
patterns spaced at 1-U [1.75 in. (4.5 cm)] increments.
• The mounting brackets and front-mount flanges used to attach the
chassis to a rack are designed to fasten to holes spaced at rack distances
of 1-U (3.5 in.).
•
The mounting holes in the mounting brackets provided with the device
are spaced 1.25 in. (3.2 cm) apart (top and bottom mounting hole).
Spacing of
mounting bracket
and flange holes
Always secure the rack in which you are installing the JSA3800 appliance
to the structure of the building. If your geographical area is subject to
earthquakes, bolt the rack to the floor. For maximum stability, also secure
the rack to ceiling brackets. Connecting to the
building structure
