Mounting Requirements
Each 24.5 in. (62.23 cm.) height chassis requires 14 Rack Units (RUs) of space. You can mount the system into any 19-
inch (482.6 mm) equipment rack or telco cabinet with the mounting brackets supplied with the chassis. Additional
hardware (not supplied), such as extension brackets, may be used to install the chassis in a standard 23-inch (584.2 mm)
cabinet or rack. Both front and mid-mount installations are possible, depending on the position of the mounting brackets
on the chassis.
You can mount a maximum of three ASR 5000 chassis in a 2- or 4-post equipment rack or telco cabinet, provided that
all system cooling and ventilation requirements are met. Three stacked chassis will occupy a minimum of 42 RUs.
Caution: When planning chassis installation, ensure that equipment rack or cabinet hardware does not hinder
air flow at any of the intake or exhaust vents. Also, make sure that the rack/cabinet hardware, as well as the ambient
environment, allow the system to function within the required limits. For more information, refer to Environmental
Specifications in this guide.
Rack mounting requires the use of industry-standard (EIA-310-D, IEC 60297) equipment racks and cabinets, as well as
supplier-recommended fasteners. The following figure depicts how three chassis can be mounted in a 42 RU equipment
rack.
