Equipment Rack Configuration
The chassis is designed for installation in a standard 19-inch (48.26 cm) equipment rack. Additional rack
hardware, such as extension brackets, may be used to install the chassis in a standard 23-inch (58.42 cm) rack.
Each chassis is 24.50 inches (62.23 cm) high. This equates to roughly 14 Rack Mount Units (RMUs: 1 RMU
= 1.75 in (4.45 cm).
You can mount a maximum of three chassis in a standard 48 RMU (7 ft.) equipment rack or telco cabinet
provided that all system cooling and ventilation requirements are met. A fully-loaded rack with three chassis
installed has approximately 5.5 inches (13.97 cm, 3.14 RMUs) of vertical space remaining.
When planning chassis installation, take care to ensure that the equipment rack or cabinet hardware does
not hinder air flow at any of the intake or exhaust vents. Additionally, ensure that the environmental control
system (HVAC) allows the system to function within the required limits.
