Table 21: SRX210 Services Gateway Cabinet Requirements
Specifications
Cabinet
Requirements
19 in. (48.3 cm) as defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310–D) published by the Electronics
Industry Association (http://www.eia.org).
You can mount the services gateway horizontally in the cabinet.
Cabinet size
■
The cabinet is at least 1 U (1.75 in. or 4.5 cm) high.
■
The outer edges of the mounting brackets extend the width of either
chassis to 19 in. (48.2 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: The holes for the mounting brackets chassis are spaced 1.25 in. (3.2
cm) apart, measured from the center of the hole.
Clearance
requirements
■
Ensure sufficient ventilation through the cabinet is sufficient to prevent
overheating.
■
Ensure adequate cool air supply to dissipate the thermal output of the
device.
■
Install the device 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.
■
Route and dress all cables to minimize the blockage of airflow to and
from the chassis.
NOTE: A cabinet larger than the minimum required provides better airflow
and reduces the chance of overheating.
