SRX300 Services Gateway Cabinet Size and Clearance Requirements
You can install the SRX300 Services Gateway in a 19 in. (48.7 cm) cabinet as defined in
Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D)
published by the Electronic Industries Alliance (http://www.ecaus.org/eia/site/index.html).
You must mount the services gateway horizontally in the cabinet using appropriate rack
adapters.
When selecting a cabinet, ensure that it meets the following specifications:
The cabinet is at least 1U (3.50 in. or 8.89 cm) and can accommodate the services
gateway.
The outer edges of the mounting brackets extend the width of either chassis to 19 in.
(48.7 cm), and the front of the chassis extends approximately 0.5 in. (1.27 cm) beyond
the mounting brackets.
The minimum total clearance inside the cabinet is 30.7 in. (78 cm) between the inside
of the front door and the inside of the rear door.
NOTE: A cabinet larger than the minimum required provides better airflow
and reduces the chance of overheating.
