Clearance Requirements for Airflow and Hardware Maintenance on the SRX240 Services Gateway
When planning the installation site for the 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 remove and install hardware components, there must be adequate space at the front and back of the device.
- If you are using an SRX240 Services Gateway High Memory with DC Power Supply model, ensure that you follow the NEBS recommendation — The NEBS GR-63 recommends that you allow at least 30 in. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the rack.
- 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 1 provides information on the clearance requirements for maintaining the optimum airflow and the distances for facilitating easy maintenance of the device.
