Guideline
Cabinet
Requirement
•
The outer edges of the mounting brackets extend the width of the chassis
to 19 in. (48.2 cm).
• The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between
the inside of the front door and the inside of the rear door.
Cabinet clearance
When you mount services gateway in a cabinet, you must ensure that
ventilation through the cabinet is sufficient to prevent overheating.
• Install the services gateway as close as possible to the front of the cabinet
so that the cable management system clears the inside of the front door.
Installing the chassis close to the front of the cabinet maximizes the
clearance in the rear of the cabinet for critical airflow.
• Ensure adequate cool air supply to dissipate the thermal output of the
services gateway.
• Route and dress all cables to minimize the blockage of airflow to and from
the chassis.
• A cabinet larger than the minimum required provides better airflow and
reduces the chance of overheating.

Gateways
When planning the installation site, you need to allow sufficient clearance around the
services gateway. Consider the following:
•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. See
