Clearance Requirements for Airflow and Hardware Maintenance on the J-SRX240
Services Gateway
When planning the installation site for the J-SRX240 Services Gateway, you need to
allow sufficient clearance around the rack.
When planning the installation site for the services gateway, consider the following:
• For the cooling system to function properly, the airflow around the chassis must be
unrestricted.
•
For service personnel to service the device, there must be adequate space at the front
and back of the device. Allow at least 24 in. (61 cm) both in front of and behind the
device.
•
If you are mounting the device in a rack with other equipment, or if you are placing it
on the desktop near other equipment, ensure that the exhaust from other equipment
does not blow into the intake vents of the chassis.
Table 20 on page 40 provides information on the clearance requirements for maintaining
the optimum airflow and the distances for facilitating easy maintenance of the device.
