Optical ILA Cabinet Requirements

You can mount optical ILA models in a cabinet that contains a two-post 19-in. or four-post rack as defined
in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-E) published by the
Electronics Components Industry Association (http://www.ecianow.org/).
Cabinet requirements consist of:
Cabinet size and clearance
Cabinet airflow requirements
Table 17 on page 48 provides the cabinet requirements and specifications for the optical ILA.
Guidelines
The holes in the mounting brackets are spaced at 1.25 in. (or 3.17 cm), so that the optical
ILA can be mounted in any rack that provides holes spaced at that distance.
Ensure that the rack complies with the standards for a 19-in. or 23-in. rack as defined
in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D)
published by the Electronics Components Industry Association
(http://www.ecianow.org/).
Ensure that the rack rails are spaced widely enough to accommodate the optical ILA
chassis. The outer edges of the front-mounting brackets extend the width to 19 in.
(48.26 cm).
Ensure that the front and rear rack rails are spaced between 28 in. (71.1 cm) and 36 in.
(91.4 cm) front-to-back.
Ensure that the rack is strong enough to support the weight of the optical ILA.
Ensure that the spacing of rails and adjacent racks allows for proper clearance around
the optical ILA and rack.
Secure the rack to the building structure.
If earthquakes are a possibility in your geographical area, secure the rack to the floor.
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum
stability.
