Table 20 on page 48 provides the details on cabinet size, clearance,and airflow requirements.Table 20: J-SRX210 Services Gateway Cabinet RequirementsSpecificationsCabinetRequirements19 in. (48.3 cm) as defined in Cabinets, Racks, Panels, and AssociatedEquipment (document number EIA-310–D) published by the ElectronicsIndustry 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 chassisto 19 in. (48.2 cm), and the front of the chassis extends approximately 0.5in. (1.27 cm) beyond the mounting brackets.• The minimum total clearance inside the cabinet is 30.7 in. (78 cm) betweenthe 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. (3.2cm) apart, measured from the center of the hole.Clearancerequirements• Ensure sufficient ventilation through the cabinet is sufficient to preventoverheating.• Ensure adequate cool air supply to dissipate the thermal output of thedevice.• Install the device as close as possible to the front of the cabinet so thatthe cable management system clears the inside of the front door. Installingthe chassis close to the front of the cabinet maximizes the clearance inthe rear of the cabinet for critical airflow.• Route and dress all cables to minimize the blockage of airflow to and fromthe chassis.NOTE: A cabinet larger than the minimum required provides better airflowand reduces the chance of overheating.Cabinet airflowrequirementsRelated Topics General Site Guidelines for Installing the J-SRX210 Services Gateway on page 47•• Site Preparation Checklist for the J-SRX210 Services Gateway on page 45• J-SRX210 Services Gateway Rack Requirements on page 4948PowerConnect J-SRX210 Services Gateway Hardware Guide
