Table 21: Cabinet Requirements and Specifications

Cabinet
Requirement Guidelines
Cabinet size You can mount the Junos Pulse Gateway in a cabinet that contains a 19-in.
rack as defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Industry
Association (http://www.eia.org).
NOTE: The rack must meet the strength requirements to support the weight
of the Junos Pulse Gateway.
The minimum cabinet size must be accommodate the maximum external
dimensions of the Junos Pulse Gateway.
Cabinet The outer edges of the mounting brackets extend the width of the chassis to
clearance 19-in. (48.3-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 When you mount the Junos Pulse Gateway in a cabinet, ensure that ventilation
airflow through the cabinet is sufficient to prevent overheating.
Ensure adequate cool air supply to dissipate the thermal output of the Junos

Pulse Gateway.

Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet
without recirculating into the Junos Pulse Gateway. An open cabinet (without
a top or doors) that employs hot air exhaust extraction from the top allows
the best airflow through the chassis. If the cabinet has a top or doors,
perforations in them can help remove the hot air exhaust.
Install the Junos Pulse Gateway in the cabinet in a way that maximizes the
open space on the side of the chassis with the hot air exhaust. This maximizes
the clearance for critical airflow.
Route and dress all cables to minimize the blockage of airflow to and from
the chassis.
Ensure that the spacing of rails and adjacent cabinets allows for proper
clearance around the Junos Pulse Gateway and cabinet.
A cabinet larger than the minimum required provides better airflow and
reduces the chance of overheating.

When planning the installation site for the Junos Pulse Gateway, you need to allow
sufficient clearance around the rack or cabinet where you are planning to install the
device.
