Rack Size and Strength
The PTX5000 is designed for installation in a rack that complies with either of the following standards:
• A 19-in. rack as defined in
EIA-310-D) published by the Electronics Components Industry Association
www.ecianow.org/).
• A 600-mm rack as defined in the four-part
telecommunications standard for equipment practice (document numbers ETS 300 119-1 through
119-4) published by the European Telecommunications Standards Institute
horizontal spacing between the rails in a rack that complies with this standard is usually wider than
the mounting brackets, which measure 19 in. (48.3 cm) from outer edge to outer edge. Use approved
wing devices to narrow the opening between the rails as required.
