When planning the installation site for the SRX210 Services Gateway, you need to allow
sufficient clearance around the rack or cabinet where you are planning to install the
device.
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. Allow at least 24 in. (61 cm) both
in front of and behind the device.
